Renewables became the second-most prevalent U.S. electricity source in 2020

U.S. Solar Panel Shipments 2021 surged to 28.8 million kW of PV modules, tracking utility-scale and small-scale capacity additions, driven by imports from Asia, resilient demand, supply chain constraints, and declining prices.

Key Points

Record 28.8M kW PV modules shipped in 2021; 80% imports; growth in utility- and small-scale capacity with lower prices.

✅ 28.8M kW shipped, up from 21.8M kW in 2020 (record capacity)

✅ 80% of PV module shipments were imports, mainly from Asia

✅ Utility-scale +13.2 GW; small-scale +5.4 GW; residential led

U.S. shipments of solar photovoltaic (PV) modules (solar panels) rose to a record electricity-generating capacity of 28.8 million peak kilowatts (kW) in 2021, from 21.8 million peak kW in 2020, based on data from our Annual Photovoltaic Module Shipments Report. Continued demand for U.S. solar capacity drove this increase in solar panel shipments in 2021, as solar's share of U.S. electricity continued to rise.

U.S. solar panel shipments include imports, exports, and domestically produced and shipped panels. In 2021, about 80% of U.S. solar panel module shipments were imports, primarily from Asia, even as a proposed tenfold increase in solar aims to reshape the U.S. electricity system.

U.S. solar panel shipments closely track domestic solar capacity additions; differences between the two usually result from the lag time between shipment and installation, and long-term projections for solar's generation share provide additional context. We categorize solar capacity additions as either utility-scale (facilities with one megawatt of capacity or more) or small-scale (largely residential solar installations).

The United States added 13.2 gigawatts (GW) of utility-scale solar capacity in 2021, an annual record and 25% more than the 10.6 GW added in 2020, according to our Annual Electric Generator Report. Additions of utility-scale solar capacity reached a record high, reflecting strong growth in solar and storage despite project delays, supply chain constraints, and volatile pricing.

Small-scale solar capacity installations in the United States increased by 5.4 GW in 2021, up 23% from 2020 (4.4 GW), as solar PV and wind power continued to grow amid favorable government plans. Most of the small-scale solar capacity added in 2021 was installed on homes. Residential installations totaled more than 3.9 GW in 2021, compared with 2.9 GW in 2020.

The cost of solar panels has declined significantly since 2010. The average value (a proxy for price) of panel shipments has decreased from $1.96 per peak kW in 2010 to $0.34 per peak kW in 2021, as solar became the third-largest renewable source and markets scaled. Despite supply chain constraints and higher material costs in 2021, the average value of solar panels decreased 11% from 2020.

In 2021, the top five destination states for U.S. solar panel shipments were:

California (5.09 million peak kW)
Texas (4.31 million peak kW)
Florida (1.80 million peak kW)
Georgia (1.15 million peak kW)
Illinois (1.12 million peak kW)
These five states accounted for 46% of all U.S. shipments, and 2023 utility-scale project pipelines point to continued growth.

Canada Renewable Energy Partnerships advance wind power and clean electricity in Alberta and Saskatchewan, cutting emissions and supporting net-zero goals through Capital Power and SaskPower agreements with Indigenous participation and 25-year supply contracts.

Key Points

Government-backed deals with Capital Power and SaskPower to deliver clean electricity and reduce emissions.

✅ 25-year renewable supply for federal facilities

✅ New Halkirk 2 Wind project in Alberta

✅ Emissions cuts with Indigenous participation

The Government of Canada has partnered with two major energy providers in Western Canada (Prairie provinces) on renewable energy projects.

Tourism Minister Randy Boissonnault appeared in Edmonton on Friday to announce a new Alberta wind-generation facility in partnership with Capital Power.

It's one of two new energy partnerships in Western Canada as part of the 2030 emissions reduction plan by Public Services and Procurement Canada.

On Jan. 1, the federal government awarded a contract worth up to $500 million to Capital Power to provide all federal facilities in Alberta with renewable electricity as part of Alberta's renewable energy surge for 25 years.

"We're proud to partner with the government of Canada to help them reach their 100 per cent clean electricity by 2025 goal," said Jason Comandante, Capital Power vice president of commercial services.

The agreement also includes opportunities for Indigenous participation, including facility development partnerships and employment and training opportunities.

"At Capital Power, we are committed to net-zero by 2045, and are proud to take action against climate change. Collaborative agreements like this help support our net-zero goals, provide us opportunities to meaningfully engage Indigenous communities, and help decarbonize Alberta's power grid," Comandante said.

Capital Power will provide around 250,000 megawatt-hours of electricity each year through existing renewable energy credits while the new Capital Power Halkirk 2 Wind facility is being developed.

Located near Paintearth, Alta., the proposed wind farm will have up to 35 turbines and generate enough power for the average yearly electricity needs of more than 70,000 Alberta homes.

The project is currently awaiting regulatory approval, within Alberta's energy landscape, with construction projected to begin this summer. When complete, it will supply 49 per cent of its output to the federal government.

"Through the agreement, the federal government is supporting the ongoing development of renewable energy infrastructure development within the province," Boissonnault said.

The new partnership will join another in Saskatchewan and complement Alberta solar facilities that have been contracted at lower cost than natural gas.

In 2022, the federal government signed an agreement with SaskPower to supply clean electricity to the approximately 600 federal facilities in Saskatchewan. That wind project is expected to come online by 2024.

Boissonnault said the two initiatives combined will reduce carbon dioxide emissions in Alberta and Saskatchewan by about 166 kilotonnes.

"That is the equivalent of the emissions from more than 50,000 cars driven for one year. So, if you think about that, that's a great reduction right here in Alberta and Saskatchewan," he said.

"These are concrete steps to ensuring that Canada remains a leader of renewable energy on the global stage and grid modernization projects to help the fight against climate change."

UK Home Solar Panel Installation drives self-consumption as PV panels, hybrid inverters, and smart meters cut grid demand, enable EV charging, and prepare battery storage, even in cloudy winters, with app-based monitoring and MCS-certified installers.

Key Points

A residential PV setup reducing grid reliance via panels, hybrid inverters, smart meters, and battery-ready design.

✅ Cuts grid use; boosts self-consumption with PV generation

✅ Hybrid inverters enable future battery storage integration

✅ Smart meter and app monitor output, EV charging patterns

In a town north of London, the weather's been cloudy over the winter months. But it didn't stop this homeowner from installing solar panels in December.

On his smart metre, Kumi Thiruchelvam looks satisfied at the "0 watts" showing up under electricity. It's about 10 am, and he's not using any electricity from the grid.

Cost of installation? Between £12,000 and £13,000 (€13,500-€14,500), a fair chunk of savings, even for Thiruchelvam, who lives on a private avenue in Luton.

The investment was common sense for him following the surge in energy prices caused by the Russian invasion of Ukraine.

According to the Office of National Statistics, electricity prices in the UK had increased by 67 per cent in January 2023 compared to January 2022, while pilots show parked EVs can earn from grids in Europe, offering some relief.

Solar power installations doubled in 2022 compared to 2021, according to MCS, the standards organisation in charge of solar installations, a shift aligned with the UK grid's net-zero transition underway today.

"We've had a combination of soaring energy prices around the world, and then also we've increased our electricity consumption in the home through a number of reasons, including electric vehicles and emerging EV-solar integration trends," says Thiruchelvam.

His family owns a big house and no less than three electric vehicles, some of which can now power a home for days during outages, so their electricity consumption is higher than the normal household, about 12,000 kWh per year.

Around two-thirds should now be provided by solar panels, and EV owners can sell electricity back to the grid in some schemes as well, diversifying benefits.

"We originally sought the configuration to be rear, which is where the sun comes up, but we went for the front because it spends more time in the front throughout most of the year than in the rear. Also, there's more shade in the rear with trees," he says.

To get a quote for the installation, Thiruchelvam used Otovo, a Norwegian company which recently launched in the UK.

Using their app, he can monitor the electricity generated by his photovoltaic (PV) installation from his phone. The data comes from the inverters installed in the attic.

Their role is to change the direct current generated by the solar panels into alternating current to power appliances in the house safely.

They also communicate with the grid and monitor the electricity generated, supporting emerging vehicle-to-building charging strategies for demand management.

"We went for two hybrid inverters, allowing me to use a battery in the future or tap stored EV energy for buildings if needed," says Thiruchelvam.

"But because battery technology is still evolving, I chose not to. And also I viewed at that time that we would be consuming everything we'd be generating. So we didn't. But most likely I will upgrade the system as we approach summer with batteries."

EPA Auto Emissions Proposal 2027-2032 sets strict tailpipe emissions limits, accelerating electric vehicle adoption, cutting greenhouse gases, advancing climate policy, and reducing oil dependence through battery-electric cars and trucks across U.S. markets.

Key Points

An EPA plan setting strict tailpipe limits to drive EV adoption, cut greenhouse gases, and reduce oil use in vehicles.

✅ Cuts GHGs 56% vs. 2026 standards; improves national air quality.

✅ Targets up to two-thirds EV sales by 2032 nationwide.

✅ Reduces oil imports by about 20 billion barrels; lowers costs.

The Biden administration is proposing strict new automobile pollution limits that would require up to two-thirds of new vehicles sold in the U.S. to be electric by 2032, a nearly tenfold increase over current electric vehicle sales.

The proposed regulation, announced Wednesday by the Environmental Protection Agency, would set tailpipe emissions limits for the 2027 through 2032 model years that are the strictest ever imposed — and call for far more new EV sales than the auto industry agreed to less than two years ago, a shift aligned with U.S. EV sales momentum in early 2024.

If finalized next year as expected, the plan would represent the strongest push yet toward a once almost unthinkable shift from gasoline-powered cars and trucks to battery-powered vehicles, as the market approaches an inflection point in adoption.

The Biden administration is proposing strict new automobile pollution limits that would require up to two-thirds of new vehicles sold in the U.S. to be electric by 2032, a nearly tenfold increase over current electric vehicle sales.

The proposed regulation, announced Wednesday by the Environmental Protection Agency, would set tailpipe emissions limits for the 2027 through 2032 model years that are the strictest ever imposed — and call for far more new EV sales than the auto industry agreed to less than two years ago, a direction mirrored by Canada's EV sales regulations now being finalized.

If finalized next year as expected, the plan would represent the strongest push yet toward a once almost unthinkable shift from gasoline-powered cars and trucks to battery-powered vehicles, with many analysts forecasting widespread adoption within a decade among buyers.

Reaching half was always a “stretch goal," given that EVs still trail gas cars in market share and contingent on manufacturing incentives and tax credits to make EVs more affordable, he wrote.

“The question isn’t can this be done, it’s how fast can it be done,” Bozzella wrote. “How fast will depend almost exclusively on having the right policies and market conditions in place.”

European car maker Stellantis said that, amid broader EV mandate debates across North America, officials were “surprised that none of the alternatives” proposed by EPA "align with the president’s previously announced target of 50% EVs by 2030.''

Q. How will the proposal benefit the environment?

A. The proposed standards for light-duty cars and trucks are projected to result in a 56% reduction in projected greenhouse gas emissions compared with existing standards for model year 2026, the EPA said. The proposals would improve air quality for communities across the nation, and, with actual benefits influenced by grid mix — for example, Canada's fossil electricity share affects lifecycle emissions — avoiding nearly 10 billion tons of carbon dioxide emissions by 2055, more than twice the total U.S. CO2 emissions last year, the EPA said.

The plan also would save thousands of dollars over the lives of the vehicles sold and reduce U.S. reliance on approximately 20 billion barrels of oil imports, the agency said.

California EV Sales 2023 show rising BEV market share, strong Tesla Model Y and Model 3 demand, hybrid growth, and ICE decline, per CNCDA Q3 data, underscoring California auto trends and ZEV policy momentum.

Key Points

BEVs hit 21.5% YTD in 2023 (22.3% in Q3); 35.4% with hybrids, as ICE share fell and Tesla led the California market.

✅ BEVs 21.5% YTD; 22.3% in Q3 per CNCDA data

✅ Tesla Model Y, Model 3 dominate; 62.9% BEV share

✅ ICE share down to 64.6%; hybrids lift to 35.4% YTD

The California New Car Dealers Association (CNCDA) reported on November 1, 2023, that sales of battery electric cars accounted for 21.5% of new car sales in the Golden State during the first 9 months of the year and 22.3% in the third quarter. At the end of Q3 in 2022, sales of electric cars stood at 16.4%. In 2021, that number was 9.1%. So, despite all the weeping and wailing and gnashing of teeth lately about green new car wreck warnings in some coverage, the news is pretty good, at least in California.

When hybrid and hydrogen fuel cell vehicles are included in the calculations, the figure jumps up 35.4% for all vehicles sold year to date in California. Not surprisingly this means EVs still trail gas cars in the state, with the CNCDA reporting ICE market share (including gasoline and diesel vehicles) was 64.6% so far this year, down from 71.6% in 2022 and 88.4% in 2018.

California is known as the vanguard for automotive trends in the country, with shifts in preferences and government policy eventually spreading to the rest of the country. While the state’s share of electric cars exceeds one fifth of all vehicles sold year to date, the figure for the US as a whole stands at 7.4%, with EV sales momentum into 2024 continuing nationwide. California has banned the sale of gas-powered vehicles starting in 2035, and its push toward electrification will require a much bigger grid to support charging, although the steady increase in the sale of electric cars suggests that ban may never need to be implemented as people embrace the EV revolution.

Not surprisingly, when digging deeper into the sales data, the Tesla Model Y and Model 3 dominate sales in the state’s electric car market this year, at 103,398 and 66,698 respectively. Tesla’s overall market share of battery electric car sales is at 62.9%. In fact, the Tesla Model Y is the top selling vehicle overall in California, followed by the Model 3, the Toyota RAV4 (40,622), and the Toyota Camry (39,293).

While that is good news for Tesla, its overall market share has slipped from 71.8% year to date last year at this time. Competing models from brands like Chevrolet, BMW, Mercedes, Hyundai, Volkswagen, and Kia have been slowly eating into Tesla’s market share. Overall, in California, Toyota is the sales king with 15% of sales, even as the state leads in EV charging deployment statewide, followed by Tesla at 13.5%. In the second quarter, Tesla narrowly edged out Toyota for top sales in the state before sales swung back in Toyota’s favor in the third quarter.

That being said, Tesla’s sales in the state climbed by 38.5% year to date, while Toyota’s actually shrank by 0.7%. Time will tell if Tesla’s popularity with the state’s car buyers improves and it can overtake Toyota for the 2023 crown, even as U.S. EV market share dipped in early 2024, or if other EV makers can offer better products at better prices and lure California customers who want to purchase electric cars away from the Tesla brand. Certainly, no company can expect to have two thirds of the market to itself forever.

Floating Solar at Fort Bragg delivers a 1 MW DoD-backed floatovoltaic array on Big Muddy Lake, boosting renewable energy, resilience, and efficiency via water cooling, with Duke Energy and Ameresco supporting backup power.

Key Points

A 1 MW floating PV array on Big Muddy Lake, built by the US Army to boost efficiency, resilience, and backup power.

✅ 1 MW array supplies backup power for training facilities.

✅ Water cooling improves panel efficiency and output.

✅ Partners: Duke Energy, Ameresco; DoD's first floating solar.

Floating solar had a moment in the spotlight over the weekend when the US Army unveiled a new solar plant sitting atop the Big Muddy Lake at Fort Bragg in North Carolina. It’s the first floating solar array deployed by the Department of Defense, and it’s part of a growing current of support in the US for “floatovoltaics” and other innovations like space-based solar research.

The army says its goal is to boost clean energy, support goals in the Biden solar plan for decarbonization, reduce greenhouse gas emissions, and give the nearby training facility a source of backup energy during power outages. The panels will be able to generate about one megawatt of electricity, which can typically power about 190 homes, and, when paired with solar batteries, enhance resilience during extended outages.

The installation, the largest in the US Southeast, is a big win for floatovoltaics, and projects like South Korea’s planned floating plant show global momentum for the technology, which has yet to make a big splash in the US. They only make up 2 percent of solar installations annually in the country, according to Duke Energy, which collaborated with Fort Bragg and the renewable energy company Ameresco on the project, even as US solar and storage growth accelerates nationwide.

Upfront costs for floating solar have typically been slightly more expensive than for its land-based counterparts. The panels essentially sit on a sort of raft that’s tethered to the bottom of the body of water. But floatovoltaics come with unique benefits, complementing emerging ocean and river power approaches in water-based energy. Hotter temperatures make it harder for solar panels to produce as much power from the same amount of sunshine. Luckily, sitting atop water has a cooling effect, which allows the panels to generate more electricity than panels on land. That makes floating solar more efficient and makes up for higher installation costs over time.

And while solar in general has already become the cheapest electricity source globally, it’s pretty land-hungry, so complementary options like wave energy are drawing interest worldwide. A solar farm might take up 20 times more land than a fossil fuel power plant to produce a gigawatt of electricity. Solar projects in the US have already run into conflict with some farmers who want to use the same land, for example, and with some conservationists worried about the impact on desert ecosystems.
