The 4 things needed to reach Biden’s ambitious 2050 solar goal
A report on the future of solar energy from the Department of Energy paints a sunny picture, if you will, of the next three decades, at the end of which nearly half the country’s energy will be provided by the sun. But for that to happen, big pushes need to happen along four major lines: better photovoltaics, more energy storage, lower soft costs, and putting about a million people to work.
Here’s what the report says needs to happen in each of these sectors in order to meet the ambitious goals it sets out.
Better photovoltaics
The solar cells themselves will need to continue to improve in both cost and efficiency in order to achieve the kind of installation volumes hoped for by the DOE. For reference, 2020 saw 15 gigawatts worth of solar installed, the most ever — but we’re going to need to double that installation rate by 2025, then double it again by 2030.
If photovoltaics don’t improve in efficiency, that means these already ambitious numbers need to go even higher to account for that. And if they stay at today’s prices, the costs will be too high to achieve those volumes as well.
Photovoltaics have come a long way, but they also have a long way to go.
Fortunately efficiency is going up and cost is going down already. But it’s not like that just happens naturally. Companies and researchers across the globe have spent millions on new manufacturing processes, new materials, and other improvements, incremental individually but which add up over time. This basic research and advancement of the science and methods around solar must continue at or beyond the pace that they have over the last two decades.
The DOE suggests that research along the lines of making more exotic PVs cheaper, or stacking cells to minimize bandgap-related losses could be crucial. Flexible and tile- or shingle-like substrates or semi-transparent installations that pass light through to crops or building interiors may also figure. Altogether the plan calls for a reduction of the overall cost to drop by almost half from $1.30/watt today on average to $0.70 by 2030 and more after that.
Solar concentrators get their own heading in the report, and many companies are looking into these to replace industrial processes. These will not likely be used to support the grid at large but will nevertheless replace many fossil fuel based processes.
More energy storage
An unavoidable consequence of getting your energy from the sun is that at night you must rely on stored energy in some form or another, originally nuclear or coal but increasingly a form of storage that collects excess power collected during the daytime. With more of peak usage being covered by renewables, cities can safely transition away from carbon-based energy sources.
While we often think of energy storage in terms of batteries, and certainly they will be present, but the amount of energy that must be stored rules out something like lithium-ion batteries as the primary storage mechanism. Instead, the excess energy can be put towards powering energy-hungry renewable fuel production, like hydrogen fuel cells. This fuel can then be used to generate power when solar can’t meet demand.
The diagram shows how demand would normally go (purple) then how it would go with solar (orange) and how energy storage could mitigate that load (solid colors).
That’s just the “off the top of the head” answer. As the report states: “Thermal, chemical, and mechanical storage technologies are under various stages of development, including pumped thermal storage, liquid air energy storage, novel gravity-based technologies, and geological hydrogen storage.”
No doubt there will be a variety of new and old technologies working to provide the various levels of energy redundancy and storage duration needs of the country. These will go a long way towards making solar and other renewable energy sources capable of being relied on for a greater proportion of demand.
Lower soft costs
If we’re going to double and redouble the rate of solar cell deployment, the costs have to come down not just for the cells themselves, but the whole end-to-end process: assessment, accounting, labor, and of course the profit due to the companies that will be doing the actual work.
Lowering non-hardware costs is already the goal of many startups, like Aurora Solar, which clearly saw the writing on the wall and started making it as easy as possible to plan, visualize, and sell solar installations entirely online.
Right now the all-in cost of a solar roof might be twice the cost of the hardware or more. There are several contributors to this, from financing to regulations to markets, and each has its own intricacies beyond the scope of this article. Suffice it to say that if you can shave one percent off the cost of a solar installation by streamlining the time or cost involved in any of these areas, there will be more than enough volume to turn that one point into a major sum. It will take the combined efforts of many organizational and commercial minds to make this happen, just as it takes the efforts of many scientific ones to improve PVs.
A million jobs
Last but certainly not least, someone has to actually do all this work. That means a whole lot of labor — several times the quarter million people currently estimated to be attached to the solar industry in the country today.

Jobs in this sector will run the gamut, from skilled workers with construction experience to energy professionals who’ve managed grids to public-private partnership wizards who connect commerce to the government’s inevitable top-down incentives. The additional half a million to a million jobs will almost certainly comprise many brand new companies and sub-industries, but the general breakdown so far has been about 65 percent installation and project development, 25 percent sales and manufacturing, and the rest in miscellaneous roles.
It is worth noting, however, that energy concerns currently clinging with white knuckles to aging oil and coal infrastructure will need to do right by the tens of thousands they still employ, and the renewable energy sector is a perfect transition space. “Throughout the transition, certain fossil fuel companies may come under increasing financial distress,” the report reads, which is something of an understatement. The authors strongly suggest funding transition programs that cover training, relocation, and guarantees of existing financial benefits like pensions.
The report points out that the solar industry is overwhelmingly white and male, like a few others we could name, so it is probably worth putting in work on that front if the million hires are to be at all equitable.

Cruise is buying solar energy from California farmers to power its electric, self-driving fleet
Cruise, the self-driving car company under General Motors, has launched a new initiative called Farm to Fleet that will allow the company to source solar power from farms in California’s Central Valley. The San Francisco Chronicle was the first to report the news that Cruise is directly purchasing renewable energy credits from Sundale Vineyards and Moonlight Companies to help power its fleet of all-electric autonomous vehicles in San Francisco.
Cruise recently secured a permit to shuttle passengers in its test vehicles in San Francisco without a human safety operator behind the wheel. The company is also ramping up its march to commercialization with a recent $5 billion line of credit from GM Financial to pay for hundreds of electric and autonomous Origin vehicles. While this partnership with California farmers is undoubtedly a boon to the state’s work in progressing renewable energies while also providing jobs and financial opportunities to local businesses, Cruise isn’t running a charity here.
The California Independent System Operator has been soliciting power producers across the western United States to sell more megawatts to the state this summer in anticipation of heat waves that will boost electricity demand and potentially cause blackouts. Power supplies are lower than expected already due to droughts, outages and delays in bringing new energy generation sources to the grid, causing reduced hydroelectric generation. To ensure California’s grid can handle the massive increase in fleet size Cruise is planning, it seems that the company has no choice but to find creative ways to bolster the grid. Cruise, however, is holding firm that it’s got loftier goals than securing the energy from whatever sources are available.
“This is entirely about us doing the right thing for our cities and communities and fundamentally transforming transportation for the better,” Ray Wert, a Cruise spokesperson, told TechCrunch.
With droughts continuing to plague California farmers, converting farmland to solar farms is a potential way to help the state meet its climate change targets, according to a report from environmental nonprofit Nature Conservancy. Which is why Cruise saw the logic in approaching Central Valley farmers now.
“Farm to Fleet is a vehicle to rapidly reduce urban transportation emissions while generating new revenue for California’s farmers leading in renewable energy,” said Rob Grant, Cruise’s vice president of social affairs and global impact, in a blog post.
Cruise is paying negotiated contract rates with the farms through its clean energy partner, BTR Energy. The company isn’t disclosing costs, but says it’s paying no more or less than what it would pay for using other forms of renewable energy credits (RECs). RECs are produced when a renewable energy source generates one megawatt-hour of electricity and passes it on to the grid. According to Cruise, Sundale has installed 2 megawatts of solar capacity to power their 200,000 square footage of cold storage, and Moonlight has installed a combined 3.9 MW of solar arrays and two-battery storage system for its sorting and storage facilities. So when Cruise buys credits from these farms, it’s able to say that a specific amount of its electricity use came from a renewable source. RECs are unique and tracked, so it’s clear where they came from, what kind of energy they used and where they went. Cruise did not share how many RECs it plans to purchase from the farms, but says it will be enough to power its San Francisco fleet.
“While the solar power still flows through the same grid, Cruise purchases and then ultimately ‘retires’ the renewable energy credits generated by the solar panels at the farms,” said Wert. “Through data that we submit to the California Air Resources Board quarterly, we retire a number of RECs equivalent to the amount of electricity we used to charge our vehicles.”
Cruise is also working with BTR Energy to finalize a supply of RECs for its operations in Arizona, including its delivery pilot with Walmart.
Wert says using fully renewable power is actually profitable for Cruise in California due to the Low Carbon Fuel Standard, which is designed to decrease the carbon intensity of transportation fuels in the state and provide more low-carbon alternatives. Cruise owns and operates all of its own EV charging ports, so it’s able to generate credits based on the carbon intensity score of the electricity and amount of energy delivered. Cruise can then sell its credits to other companies seeking to reduce their footprints and comply with regulations.
Aside from practicalities, Cruise is aiming to set a standard for the industry and create demand for renewable energy, thus incentivizing more people and businesses to create it.
Aram Shumavon, CEO of grid analytics startup Kevala, says Cruise should be applauded for this partnership.
“What Cruise seems to be trying to acknowledge is that there is carbon intensity associated with the electricity that they’re consuming, and they’re offsetting that in some way,” Shumavon told TechCrunch. “There’s a whole category of carbon accounting, that’s referred to as Scope 3, which is trying to understand how much carbon the supply chain that you use to provide your service actually involves, and Cruise is probably, as a very deliberate decision, getting out in front of their Scope 3 requirements.”
Shumavon said that by quantifying the total carbon intensity of commercial activity, companies become more accountable to it and can then drive change by asking providers for their supply to source from renewables. For example, an automaker might ask their aluminum provider to source only from an area with hydroelectric power instead of coal power, which would ultimately bring the automaker’s carbon intensity down.
“Transportation is responsible for over 40% of greenhouse gas emissions, which is why we announced our Clean Mile Challenge in February, where we challenged the rest of the AV industry to report how many miles they’re driving on renewable energy every year,” said Wert. “We’re hoping that others follow our lead.”
This article has been updated to reflect new information provided by Cruise, as well as expert commentary from Aram Shumavon, CEO of Kevala.

Exeger takes $38M to ramp up production of its flexible solar cells for self-powered gadgets
Sweden’s Exeger, which for over a decade has been developing flexible solar cell technology (called Powerfoyle) that it touts as efficient enough to power gadgets solely with light, has taken in another tranche of funding to expand its manufacturing capabilities by opening a second factory in the country.
The $38 million raise is comprised of $20M in debt financing from Swedbank and Swedish Export Credit Corporation (SEK), with a loan amounting to $12M from Swedbank (partly underwritten by the Swedish Export Credit Agency (EKN) under the guarantee of investment credits for companies with innovations) and SEK issuing a loan amounting to $8M (partly underwritten by the pan-EU European Investment Fund (EIF)); along with $18M through a directed share issue to Ilija Batljan Invest AB.
The share issue of 937,500 shares has a transaction share price of $19.2 — which corresponds to a pre-money valuation of $860M for the solar cell maker.
Back in 2019 SoftBank also put $20M into Exeger, in two investments of $10M — entering a strategic partnership to accelerate the global rollout of its tech and further extending its various investments in solar energy.
The Swedish company has also previously received a loan from the Swedish Energy Agency, in 2014, to develop its solar cell tech. But this latest debt financing round is its first on commercial terms (albeit partly underwritten by EKN and EIF).
Exeger says its solar cell tech is the only one that can be printed in free-form and different colors, meaning it can “seamlessly enhance any product with endless power”, as its PR puts it.
So far two devices have integrated the Powerfoyle tech: A bike helmet with an integrated safety taillight (by POC), and a pair of wireless headphones (by Urbanista). Although neither has yet been commercially launched — but both are slated to go on sale next month.
Exeger says its planned second factory in Stockholm will allow it to increase its manufacturing capacity tenfold by 2023, helping it target a broader array of markets sooner and accelerating its goal of mass adoption of its tech.
Its main target markets for the novel solar cell technology currently include consumer electronics, smart home, smart workplace, and IoT.
More device partnerships are slated as coming this year.

“We don’t label our rounds but take a more pragmatic view on fundraising,” said Giovanni Fili, founder and CEO. “Developing a new technology, a new energy source, as well as laying the foundation for a new industry takes time. Thus, a company like ours requires long-term strategic investors that all buy into the vision as well as the overall strategy. We have spent a lot of time and energy on this, and it has paid off. It has given the company the resources required, both time and money, to bring an invention to a commercial launch, which is where we are today.”
Fili added that it’s chosen to raise debt financing now “because we can”.
“The same answer as when asked why we build a new factory in Stockholm, Sweden, rather than abroad. We have always said that once commercial, we will start leveraging the balance sheet when securing funds for the next factory. Thanks to our long-standing relationship with Swedbank and SEK, as well as the great support of the Swedish government through EKN underwriting part of the loans, we were able to move this forward,” he said.
Discussing the forthcoming two debut gizmos, the POC Omne Eternal helmet and the Urbanista Los Angeles headphones — which will both go sale in June — Fili says interest in the self-powered products has “surpassed all our expectations”.
“Any product which integrates Powerfoyle is able to charge under all forms of light, whether from indoor lamps or natural outdoor light. The stronger the light, the faster it charges. The POC helmet, for example, doesn’t have a USB port to power the safety light because the ambient light will keep it charging, cycling or not,” he tells TechCrunch.
“The Urbanista Los Angeles wireless headphones have already garnered tremendous interest online. Users can spend one hour outdoors with the headphones and gain three hours of battery time. This means most users will never need to worry about charging. As long as you have our product in light, any light, it will constantly charge. That’s one of the key aspects of our technology, we have designed and engineered the solar cell to work wherever people need it to work.”
“This is the year of our commercial breakthrough,” he added in a statement. “The phenomenal response from the product releases with POC and Urbanista are clear indicators this is the perfect time to introduce self-powered products to
the world. We need mass scale production to realize our vision which is to touch the lives of a billion people by 2030, and that’s why the factory is being built now.”

Use today’s tech solutions to meet the climate crisis and do it profitably
Five years ago I landed the Solar Impulse 2 in Abu Dhabi after flying around the globe powered solely by solar energy, a first in aviation history.
It was also a milestone in energy and technology history. Solar Impulse was an experimental plane, weighing as little as a family car and using 17,248 solar cells. It was a flying laboratory, full of groundbreaking technologies that made it possible to produce renewable energy, store it and use it when necessary in the most efficient manner.
The time has come to use technology again to address the climate crisis affecting us all. As we enter the most crucial decade of climate action — and most likely our last chance to limit global warming to 1.5°C — we need to ensure that clean technologies become the only acceptable norm. These technologies exist now and they can be profitably implemented at this crucial moment.
Hundreds of clean tech solutions exist that protect the environment in a profitable way,
Here are just four innovations from our solar-powered plane that the market can start using now before it’s too late.
From insulating the cabin to insulating our homes
The building sector is one of the largest energy consumers in the world. Next to a reliance on carbon-heavy fuels for heating and cooling, poor insulation and associated energy loss are among the main reasons.
Inside Solar Impulse’s cockpit, insulation was crucial for the plane to fly at very high altitudes. Covestro, one of our official partners, developed an ultra-lightweight and insulating material. The cockpit insulation performance was 10% higher than the standards at the time because the pores in the insulating foam were 40% smaller, reaching a micrometer scale. Thanks to its very low density of fewer than 40 kilograms per cubic meter, the cockpit was ultra-lightweight.
This technology and many others exist. We now need to ensure that all market players are motivated to make hyperefficient building insulation their standard operating procedure.
From propelling an electric aircraft to propelling clean mobility
Solar Impulse was first and foremost an electric airplane when it flew 43,000 km without a single drop of fuel. Its four electric motors had a record-beating efficiency of 97%, far ahead of the miserable 27% of standard thermal engines. This means that they only lost 3% of the energy they used versus 73% for combustion propulsion. Today, electric vehicle sales are soaring. According to the International Energy Agency, when Solar Impulse landed in 2016, there were approximately 1.2 million electric cars on the road; the figure has now risen to over 5 million.
Nevertheless, this acceleration is far from enough. Power sockets are still far from replacing petrol pumps. The transport sector still accounts for one-quarter of global energy-related CO2 emissions. Electrification must happen much more quickly to reduce CO2 emissions from our tailpipes. To do so, governments need to boost the adoption of electric vehicles through clear tax incentives, diesel and petrol engine bans, and major infrastructure investments. 2021 should be the year that puts us on a one-way road to zero-emission vehicles and puts thermal engines in a dead end.
An aircraft microgrid can work for off-grid communities
To fly for several days and nights, reaching a theoretically endless flight potential, Solar Impulse relied on batteries that stored the energy collected during the day and used it to power its engines during the night.
What was made possible with Si2 on a small scale should guide the way to future-proofing power-generation systems that are made up entirely of renewable energy. In the meantime, microgrids, like those used in Si2, could benefit off-grid systems in remote communities or energy islands, allowing them to abolish diesel or other carbon-heavy fuels already today.
On a larger scale, we are looking at smart grids. If all “stupid grids” were replaced by smart grids, it would allow cities, for example, to manage production, storage, distribution and consumption of energy and to cut peaks in energy demand that would reduce CO2 emissions dramatically.
Energy efficiency in the air and on the ground
Solar Impulse’s philosophy was to save energy instead of trying to produce more of it. This is why the relatively small amount of solar energy we collected became enough to fly day and night. All the airplane parameters, including wingspan, aerodynamics, speed, flight profile and energy systems, had therefore been designed to minimize energy loss.
Unfortunately, this approach still stands out against the inefficiency of most of our energy use today. Even though the IEA found energy efficiency improved by an estimated 13% between 2000 and 2017, it is not enough. We need bolder action by policymakers to encourage investors. One of the best ways to do so is to put strict energy efficiency standards in place.
For example, California has set efficiency standards on buildings and appliances, such as consumer electronics and household appliances, estimated to have saved consumers more than $100 billion in utility bills. These measures are as good for the environment as they are for the economy.
Si2 was the future; now, it should define the present
When we used all these different innovations to build Solar Impulse, they were groundbreaking and futuristic. Today, they should define the present; they should be the norm. Next to the technologies mentioned above, hundreds of clean tech solutions exist that protect the environment in a profitable way, many of which have received the Solar Impulse Efficient Solution Label.
Just as for the Si2 technologies, we must now ensure that they enter the mainstream market. The faster we scale them, the faster we will set our economy on track to achieve the Paris Agreement goals and attain sustainable economic growth.

SunCulture wants to turn Africa into the world’s next bread basket, one solar water pump at a time
The world’s food supply must double by the year 2050 to meet the demands of a growing population, according to a report from the United Nations. And as pressure mounts to find new crop land to support the growth, the world’s eyes are increasingly turning to the African continent as the next potential global bread basket.
While Africa has 65% of the world’s remaining uncultivated arable land, according to the African Development Bank, the countries on the continent face significant obstacles as they look to boost the productivity of their agricultural industries.
On the continent, 80% of families depend on agriculture for their livelihoods, but only 4% use irrigation. Many families also lack access to reliable and affordable electricity. It’s these twin problems that Samir Ibrahim and his co-founder at SunCulture, Charlie Nichols, have spent the last eight years trying to solve.
Armed with a new financing model and purpose-built small solar-powered generators and water pumps, Nichols and Ibrahim have already built a network of customers using their equipment to increase incomes by anywhere from five to 10 times their previous levels by growing higher-value cash crops, cultivating more land and raising more livestock.
The company also just closed on $14 million in funding to expand its business across Africa.
“We have to double the amount of food we have to create by 2050, and if you look at where there are enough resources to grow food — all signs point to Africa. You have a lot of farmers and a lot of land, and a lot of resources,” Ibrahim said.
African small farmers face two big problems as they look to increase productivity, Ibrahim said. One is access to markets, which alone is a huge source of food waste, and the other is food security because of a lack of stable growing conditions exacerbated by climate change.
As one small farmer told The Economist earlier this year, “The rainy season is not predictable. When it is supposed to rain it doesn’t, then it all comes at once.”
Ibrahim, who graduated from New York University in 2011, had long been drawn to the African continent. His father was born in Tanzania and his mother grew up in Kenya and they eventually found their way to the U.S. But growing up, Ibrahim was told stories about East Africa.
While pursuing a business degree at NYU Ibrahim met Nichols, who had been working on large-scale solar projects in the U.S., at an event for budding entrepreneurs in New York.
The two began a friendship and discussed potential business opportunities stemming from a paper Nichols had read about renewable energy applications in the agriculture industry.
After winning second place in a business plan competition sponsored by NYU, the two men decided to prove that they should have won first. They booked tickets to Kenya and tried to launch a pilot program for their business selling solar-powered water pumps and generators.
Conceptually solar water-pumping systems have been around for decades. But as the costs of solar equipment and energy storage have declined, the systems that leverage those components have become more accessible to a broader swath of the global population.
That timing is part of what has enabled SunCulture to succeed where other companies have stumbled. “We moved here at a time when [solar] reached grid parity in a lot of markets. It was at a time when a lot of development financiers were funding the nexus between agriculture and energy,” said Ibrahim.
Initially, the company sold its integrated energy generation and water-pumping systems to the middle income farmers who hold jobs in cities like Nairobi and cultivate crops on land they own in rural areas. These “telephone farmers” were willing to spend the $5,000 required to install SunCulture’s initial systems.
Now, the cost of a system is somewhere between $500 and $1,000 and is more accessible for the 570 million farming households across the word — with the company’s “pay-as-you-grow” model.
It’s a spin on what’s become a popular business model for the distribution of solar systems of all types across Africa. Investors have poured nearly $1 billion into the development of off-grid solar energy and retail technology companies like M-kopa, Greenlight Planet, d.light design, ZOLA Electric and SolarHome, according to Ibrahim. In some ways, SunCulture just extends that model to agricultural applications.
“We have had to bundle services and financing. The reason this particularly works is because our customers are increasing their incomes four or five times,” said Ibrahim. “Most of the money has been going to consuming power. This is the first time there has been productive power.”
SunCulture’s hardware consists of 300-watt solar panels and a 440-watt-hour battery system. The batteries can support up to four lights, two phones and a plug-in submersible water pump.
The company’s best-selling product line can support irrigation for a two-and-a-half acre farm, Ibrahim said. “We see ourselves as an entry point for other types of appliances. We’re growing to be the largest solar company for Africa.”
With the $14 million in funding, from investors including Energy Access Ventures (EAV), Électricité de France (EDF), Acumen Capital Partners (ACP) and Dream Project Incubators (DPI), SunCulture will expand its footprint in Kenya, Ethiopia, Uganda, Zambia, Senegal, Togo and Cote D’Ivoire, the company said.
Ekta Partners acted as the financial advisor for the deal, while CrossBoundary provided additional advisory support, including an analysis on the market opportunity and competitive landscape, under the United States Agency for International Development (USAID)’s Kenya Investment Mechanism Program.

The Sun Exchange raises $3M for crypto-driven solar power in Africa
South Africa-based renewable energy startup Sun Exchange has raised $3 million to close its Series A funding round totaling $4 million.
The company operates a peer-to-peer, crypto-enabled business that allows individuals anywhere in the world to invest in solar infrastructure in Africa.
How’s that all work?
“You as an individual are selling electricity to a school in South Africa, via a solar panel you bought through the Sun Exchange,” explained Abe Cambridge, the startup’s founder and CEO.
“Our platform meters the electricity production of your solar panel. Arranges for the purchasing of that electricity with your chosen energy consumer, collects that money and then returns it to your Sun Exchange wallet.”
It costs roughly $5 a solar cell to get in and transactions occur in South African Rand or Bitcoin.
“The reason why we chose Bitcoin is we needed one universal payment system that enables micro transactions down to a millionth of a U.S. cent,” Cambridge told TechCrunch on a call.
He co-founded the Cape Town-headquartered startup in 2015 to advance renewable energy infrastructure in Africa. “I realized the opportunity for solar was enormous, not just for South Africa, but for the whole of the African continent,” said Cambridge.
“What was required was a new mechanism to get Africa solar powered.”
Sub-Saharan Africa has a population of roughly 1 billion people across a massive landmass and only about half of that population has access to electricity, according to the International Energy Agency.
Recently, Sun Exchange’s main market South Africa — which boasts some of the best infrastructure in the region — has suffered from blackouts and power outages.

Sun Exchange has members in 162 countries who have invested in solar power projects for schools, businesses and organizations throughout South Africa, according to company data.
The $3 million — which closed Sun Exchange’s $4 million Series A — came from the Africa Renewable Power Fund of London’s ARCH Emerging Markets Partners.
With the capital, the startup plans to enter new markets. “We’re going to expand into other Sub-Saharan African countries. We’ve got some clear opportunities on our roadmap,” Cambridge said, referencing Nigeria as one of the markets Sun Exchange has researched.
There are several well-funded solar energy startups operating in Africa’s top economic and tech hubs, such as Kenya and Nigeria. In East Africa, M-Kopa sells solar hardware kits to households on credit, then allows installment payments via mobile phone using M-Pesa mobile money. The venture is backed by $161 million from investors including Steve Case and Richard Branson.
In Nigeria, Rensource shifted from a residential hardware model to building solar-powered micro utilities for large markets and other commercial structures.
Sun Exchange operates as an asset free model and operates differently than companies that install or manufacture solar panels.
“We’re completely supplier agnostic. We are approached by solar installers who operate on the African continent. And then we partner with the best ones,” said Cambridge — who presented the startup’s model at TechCrunch Startup Battlefield in Berlin in 2017.
“We’re the marketplace that connects together the user of the solar panel to the owner of the solar panel to the installer of the solar panel.”

Sun Exchange generates revenues by earning margins on sales of solar panels and fees on purchases and kilowatt hours generated, according to Cambridge.
In addition to expanding in Africa, the startup looks to expand in the medium to long-term to Latin America and Southeast Asia.
“Those are also places that would really benefit from from solar energy, from the speed in which it could be deployed and the environmental improvements that going solar leads to,” said Cambridge.

Panasonic is ending its solar cell partnership with Tesla
Panasonic said it will stop producing solar cells and modules at Tesla’s factory in Buffalo, N.Y., ending a four-year joint venture with the electric automaker.
Nikkei Asian Review was the first to report that Panasonic planned to end its production agreement with Tesla . Panasonic has since issued an announcement to explain its decision. Tesla did not respond to a request for comment.
Panasonic said it will cease solar manufacturing operations at the Tesla factory by the end of May. The company will exit the factory by September.
Panasonic employs about 380 people at the factory. Those employees will be given severance packages. Panasonic said it will work with Tesla to identify and hire qualified applicants from its impacted workforce. Panasonic said in its announcement that Tesla plans to hire qualified applicants to new positions needed to support its solar and energy manufacturing operations in Buffalo.
Panasonic struck a deal in 2016 to jointly produce solar cells at Tesla’s “Gigafactory 2” plant in Buffalo, N.Y. Panasonic committed to share the cost of equipment needed for the plant. The joint venture deepened the relationship between the two companies, which already had established a partnership to produce battery cells at Tesla’s factory near Reno, Nev.
Panasonic’s decision to exit the factory comes as Tesla tries to scale up its energy business as well as meet employment requirements at the state-funded factory. The Buffalo factory was built with $750 million in taxpayer funds and then leased to Tesla. Under a deal reached with the state, Tesla must employ 1,460 people there by April or face a $41.2 million penalty.
As reports of Panasonic’s exit circulated, Tesla told Empire State Development, the New York economic development authority that oversees the factory, that it has exceeded its hiring commitment.
“Tesla informed us that they have not only met, but exceeded their next hiring commitment in Buffalo. As of today, Tesla said they have more than 1,500 jobs in Buffalo and more than 300 others across New York State,” Howard Zemsky, chairman of Empire State Development said in a statement.
Panasonic’s decision to move away from global solar products has no bearing on Tesla’s current operations nor its commitment to Buffalo and New York State, according to Tesla, Zemsky said.
The development authority will verify the company’s data, Zemsky said, who added that the count does not include the Panasonic positions.
Panasonic never received incentives from the state, according to Zemsky.
As Panasonic exits New York, it still works with Tesla under a separate joint venture to produce battery cells at a massive factory near Reno, Nev. Panasonic said in a statement that the decision “will have no impact on Panasonic and Tesla’s strong partnership in Nevada.” The two companies will continue their electric vehicle battery work taking place at Tesla’s Gigafactory, according to Panasonic.
In recent years, reports have suggested the relationship between Panasonic and Tesla has become strained. Tesla’s acquisition in February 2019 of Maxwell Technologies fueled speculation that the automaker wanted to develop its own battery cells.

Nigeria’s Rensource raises $20M to power African markets by solar
Nigerian startup Rensource Energy has raised a $20 million Series A round co-led by CRE Venture Capital and the Omidyar network.
The renewable energy company builds and operates solar-powered micro-utilities that provide electricity to commercial community structures, such as open-air trading bazaars.
Launched in 2016, the startup has shifted its operating strategy. “We’ve pivoted away from a residential focus…and we’re building much larger systems to become essentially the utility for these large urban markets we have a lot of in Nigeria,” Rensource co-founder Ademola Adesina told TechCrunch.
The company has a partnership with German manufacturer BOS AG, with whom it designs specialized panels for it use case. Rensource also has developer teams in Nigeria and Europe for its software-related programs.
In addition to becoming a micro-energy provider to Nigeria’s robust SME classes, the startup aims to offer them B2B services. With the $20 million round, Rensource is launching its Spaces Offline to Online platform for supply-chain services, including business-analytics and working capital options.
“It’s a mini-ERP tool. We’re trying to bring a universe of people who are banked, but…still offline — their products are offline, they don’t track anything, and there’s no data behind their business — online,” said Adesina.
The benefit Rensource seeks to deliver to Nigeria’s SMEs — at a profit for itself — is to lower overhead costs through better business practices and free them from the bane of generators.
Across marketplaces in West Africa, noisy, fuel-guzzling and pollution-producing generators are like an unwelcome, yet necessary business partner.
Lack of affordable and reliable electricity in Nigeria creates a massive real and opportunity cost to Africa’s largest economy.
For perspective, the West African country is roughly the size of Texas, with a 200 million population larger than Russia, and generates less gigawatt hours of electricity annually than the U.S. state of Connecticut.
Nigerian businesses (and citizens) adjust for these power deficiencies by spending on diesel fuel and generators.
The IMF’s 2019 Nigeria report quoted economic losses of $29 billion in Nigeria due to unreliable electricity supply. On global Doing Business rankings, Nigeria ranked 169 out of 190 countries in the category of “Getting Electricity.”
This difficulty and cost weighs particularly heavy on Nigeria (and the continent’s) SMEs, which often operate in Africa’s informal economy — projected to be one of the largest off-the grid commercial spaces in the world.
Rensource’s micro-utility model deploys power clusters — made up of solar-panels, batteries and a power management system — adjacent to markets and commercial hubs. The energy application isn’t totally clean, as the startup still uses its own diesel backup system.
Rensourse has used this model to become an off-grid energy provider in six states in Nigeria, and powers the Sabon Gari market — one of the country’s largest, located in northern Kano State.
The company plans to expand to 100 markets within Nigeria and to additional African countries within 24 months, according to Adesina.
Rensource generates revenue from charging merchants daily, weekly or monthly fees. “In 2017, we did a few hundred thousand dollars in revenue. Last year we did about $7 million in revenue, and this year we’ll do better than that,” Adesina said.
The company doesn’t release official financials, but generated a small profit last year, according to Adesina. He named deploying more of its micro-utilities to new markets and diversifying services as the path to long-term profitability.
Rensource differentiates itself from many home-kit solar energy startups in Africa, such as M-Kopa, by becoming a renewable energy utility at scale.
The startup’s CEO sees the model as a classic leapfrog tech business, effectively bypassing Nigeria’s deficient electricity grid and providing a less capital intensive alternative to large (and often complicated) energy infrastructure projects.
Rensource is also following a trend by some Nigeria-based startups, such as trucking-logistics company Kobo360 and motorcycle ride-hail company Gokada, to shape a suite of additional services around the needs of core clients.
In Rensource’s case, those clients are SMEs and traders in the informal economy. “This informality of theirs is what we see as an opportunity in building this new business line and bringing these [merchants] into the online world,” said Adesina.

Tesla is launching version three of its solar roof tile this week
Tesla will debut a new, third iteration of its solar roof tile this week — with an official debut tomorrow afternoon. Tesla CEO Elon Musk said during the company’s earnings call on Wednesday that it’ll make an official announcement detailing the differences in generation three on Thursday afternoon.
Tesla originally unveiled its solar roof tile product back in 2016, and officially opened pre-orders in 2017. During the company’s annual shareholder meeting in June, Musk said that the product was already in its third iteration, which he said improved performance and put the product on cost parity with cheap, non-solar roofing tiles, once you factor in savings over time on utility cost plus the cost of purchase for the new roof.
It seems like that version was in testing at that point, and is now ready for general consumer sales and purchase. The solar tiles have not seemed to have seen consumer installations in any kind of significant scale to date, with existing customers with reservations in place claiming they haven’t heard much in the way of installation timeline expectations. Perhaps we’ll learn more about availability and roll-out plans along with tomorrow’s “official” launch of the version-three product.

Amazon orders 100K electric delivery trucks from Rivian as part of going carbon-neutral by 2040
Amazon will be stepping up its efforts to reduce its climate impact, CEO Jeff Bezos announced on Thursday. The company will be ordering 100,000 electric delivery trucks from Michigan’s Rivian as part of this commitment, Bezos said. The commerce giant will seek to meet its goal of becoming carbon-neutral by 2040 — 10 years earlier than is outlined by the United Nations Paris Agreement.
Bezos said at a National Press Club event in Washington where he made the announcement that the updated timeline is due to the increase in climate change, which has been more aggressive than even some of the more serious predictions had anticipated five years ago when the Paris agreement was reached.
Amazon’s overarching efforts to make the company carbon-neutral are bundled under a plan the company is calling the “Climate Pledge,” which will be open to other companies as well. In addition to efforts like the Rivian order for emission-free delivery vehicles, Amazon also will be seeking to reduce its footprint through other means, including solar energy and carbon offsets.
Rivian noted that this was the largest order to date of any electric delivery vehicles, and that they’d begin actually deploying for Amazon starting in 2021. Amazon led a $700 million investment round in Rivian in February, and the company announced a further $350 million from auto industry giant Cox Automotive earlier this month. Automaker Ford revealed a $500 million investment in Rivian in April, too.
Rivian also has plans to build and ship consumer vehicles, including the all-electric pickup truck and SUV it revealed late last year, which it aims to begin delivering to customers in 2020.
