One decade ago, I was writing about the rapid growth of solar power in the United States and the exciting forecast for much more solar growth in the country. The past couple of years have again brought record solar installations in the United States, and record solar activity more broadly. Of course, this is driven in large part by record-low solar prices, but not only.

What’s Driving US Solar Power Growth?

Money, money, money — it’s hard to say that most of this growth doesn’t come down to continuous solar panel cost drops over the past decade, which as I reported last year led to an average rooftop solar power price of $2.19/watt across the USA and a Tesla rooftop solar power price of $1.49/watt across the country. Both prices are the price after the US solar tax credit, aka Investment Tax Credit (ITC), takes 26% off the consumer cost.

Related, the federal solar tax credit was on the verge of dropping from 26% of the cost of a solar power system to 22% after 2020, but it was extended at the end of the year. A desire to get the 26% credit before it was cut to 22% surely led to a solar power rush throughout the year. It turns out the tax credit was extended at the end of the year, but that doesn’t mean the systems installed due to the potential expiration are any less real.

How Much Did US Solar Power Grow In 2020?

As noted above, the big-picture view is of solar activity — or solar PV module shipments — which includes solar panel (aka solar module) imports, solar panel exports, solar panels produced, and solar panels sold domestically. (I know, it seems like a somewhat weird accumulation of different activities.) They rose to 21.8 million peak kilowatts (kW) of solar power capacity in 2020, by far their best ever. In fact, that was 5.4 million peak kW above 2019’s total, their previous best.

The U.S. Energy Information Administration adds that the COVID-19 crisis may have given rooftop solar a boost, too. “Demand for residential solar installations increased in 2020 in part because people were spending more time at home, which in turn resulted in an increased interest in home improvement.”

Though, the growth wasn’t all about rooftop solar. In fact, utility-scale solar saw an even bigger growth spurt than rooftop solar. Utility-scale solar PV installations (1 MW and above) rose by 29% in 2020, compared to 2019, whereas small-scale solar rose by 19%. The average of the two was 25% growth.

Low solar power costs combined with growing awareness and greater increase in energy self-reliance have surely led to further solar power growth in 2021, but there likely won’t be a rush induced by changes to the tax incentives again until 2022, since the 26% credit extension went through 2022, dropping to 22% in 2023 (unless it gets extended again, but that seems unlikely).

“The average value (a proxy for price) of solar shipments decreased from $1.96 per peak watt in 2010 to $0.38 per peak watt in 2020,” the EIA writes, referencing the graph above. “Lower supply chain costs and an oversupply of modules because of increased production are largely responsible for the declines in the average value of solar PV modules over the past decade.”

And here are a few more stats from the EIA team, with lead writing by Lolita Jamison: “In 2020, 89% of U.S. solar PV module shipments were imports. PV module imports in 2020 totaled 19.3 million peak kilowatts (kW), an increase of 26% from the 15.3 million peak kW imported in 2019. Vietnam was the leading importer to the United States, followed by Malaysia, South Korea, and Thailand.”

As far as where in the US all of this solar power gets installed, as could be expected, the three most populated states in the nation — each of which have more than ample solar energy resources — stand out well above the crowd. Though, #4 Virginia shows an impressively large contribution, coming out of nowhere compared to previous years (it was #14 in 2018 and #19 in 2019). North Carolina, South Carolina, and New York round out the top 7, with the first and the last in that trio very familiar with top rankings, and the middle child improving on a very solid 2019 total. Here’s a short bullet-point summary for the top 10 in 2020 since the table below is a bit hard to read (all figures in MWdc):

  1. California — 3904
  2. Texas — 3425
  3. Florida — 2822
  4. Virginia — 1406
  5. North Carolina — 785
  6. South Carolina — 617
  7. New York — 544
  8. Arizona — 503
  9. Utah — 427
  10. New Jersey — 387

2021 and Beyond

What will 2021, 2022, and 2023 bring?

The U.S. Solar Energy Industries Association (SEIA) projects that 2021 will set an even significantly stronger solar power installation record, and then will grow a bit more gradually in 2022 and 2023 before dropping off for a few years in 2024, 2025, and 2026 due to the US solar tax credit reduction.

The trends are expected to be approximately the same in both the small-scale (typically rooftop) solar PV market and the utility-scale solar PV market.

Is It Time To Go Solar?

This is always the question, and the answer is always “yes.” There are a variety of factors to consider and it’s a decision for each person, family, or business to look at closely themselves. However, year after year, it is typically the case that there’s a lot of money to be made, or saved, by going solar. If financing, the long-term savings often beat business-as-usual retail electricity purchasing. If considering a cash purchase, one can also take into account other investment opportunities and risk-reward levels. One way or another, though, going solar often makes financial sense. And when you take into account the climate catastrophe we’re facing, it’s just the right thing to do.

Considering going solar at a home or business? If so, I always recommend getting at least 3 quotes from solar installers (they’re always free), looking carefully at the terms and conditions, and consulting with someone who has already gone solar if you have the opportunity. If you end up deciding on going solar with Tesla, feel free to use my referral code — https://ts.la/zachary63404 — for a $100 discount (and a bit of a bonus for me, too). That works for either conventional solar panels or a Tesla Solar Roof (solar tiles).

OpenAI in talks with investors about share sale at 0 billion valuation

OpenAI is in talks with investors about a potential stock sale at a valuation of roughly $500 billion, according to two sources with knowledge of the matter.

The talks are in early stages and would involve a secondary sale with shares sold by current and former employees, said the people, who asked not to be named because the discussions are confidential. Thrive Capital, an investor in OpenAI, could lead the potential round, the sources said.

Bloomberg was first to report on the latest talks.

OpenAI’s valuation has been on a continuous upswing since the artificial intelligence startup launched ChatGPT in late 2022 and quickly established itself as the leader in generative AI. The company announced a $40 billion funding round in March at a $300 billion, by far the largest amount ever raised by a private tech company.

Last week, OpenAI announced its most recent $8.3 billion tranche tied to that funding round.

OpenAI released two open-weight language models on Tuesday for the first time since it rolled out GPT-2 in 2019. The models aim to serve as lower-cost options that developers and researchers can easily run and customize, OpenAI said.

The company said earlier this week that ChatGPT was about to hit 700 million weekly active users.

OpenAI rival Anthropic, meanwhile, is in talks to secure between $3 billion and $5 billion in new funding led by Iconiq Capital at a potential $170 billion valuation, up from $61.5 billion in March.

CNBC previously reported that OpenAI’s annual recurring revenue is projected to top $20 billion by year-end, up from $10 billion in June.

Chevy Bolt EUV goes full Boat Mode in Texas floodwaters [video]

Chevy Bolt EUV goes full Boat Mode in Texas floodwaters [video]

Electric cars don’t have intakes and exhausts, so they can’t get hydrolocked in deep water the way ICE-powered cars can – but that doesn’t make them amphibious. Nobody told this Texan Chevy Bolt EUV owner that, and when they got caught on the wrong side of the floodwaters, they licked the stamp and sent it!

The recent catastrophic flooding in Texas has brought unimaginable tragedies and hardships to thousands of people who unquestionably deserve better, and living through something like that can lead people to make some rash decisions (I made it through the aftermaths of Hurricanes Andrew and Katrina, AMA). Rash decisions like pulling up to a tunnel flooded in nearly three feet of water, and deciding to stand on the gas.

Think I’m exaggerating? Watch this Chevy Bolt EUV go full “Boat Mode” as its driver decides that dealing with whatever unseen obstacle or deadly live wires concealed by the floodwaters are less annoying than having to find an alternative route for yourself.

Submerging an EV that wasn’t designed for it (or even a Cybertruck, which allegedly was), isn’t exactly advisable. In addition to the underwater threats, submerging the skateboard in water could damage sensitive electrical connectors, compromise battery seals, and cause shorts in circuit boards over time.

“Even more critically, water ingress into high-voltage systems can pose serious safety risks, including electrical faults or, in rare cases, thermal events,” writes Jonathan Lopez, over at GM Authority. “Although the Bolt EUV in this instance completed its soggy journey successfully, long-term effects may still emerge.”

In other words: don’t try this at home.

Georgia launches free rooftop solar and EPA now wants to steal its grant money

Georgia launches free rooftop solar and EPA now wants to steal its grant money

Georgia BRIGHT, a statewide initiative to deliver affordable solar, kicked off its “No-Cost Solar Plan” in Atlanta yesterday, giving qualified homeowners a shot at roughly 400 fully prepaid rooftop-solar systems with zero upfront or maintenance costs. However, Georgia Bright’s No-Cost Solar Plan may lose its $156 million in grant money if the EPA steals back the Solar for All program’s entire $7 billion, which funded it.

On Earth Day (April 22) 2024, the Georgia BRIGHT Communities Coalition, including lead applicant Capital Good Fund, along with coalition member cities, Atlanta, Savannah, and Decatur, and dozens of other Georgia stakeholders, was allocated $156 million from Solar for All to bring solar to thousands of households statewide between now and mid-2029.

Families that earn 80% or less of their county’s Area Median Income can enter a drawing for the No-Cost Solar Plan now; a second drawing for another 400 systems is set for spring 2026.

“As the cost of living increases across our most vulnerable communities, this program will deliver significant savings to the households that need it most,” said Alicia Brown, director of Georgia BRIGHT.

Those savings are already showing up. Pilot participant Christine Difeliciantonio saw her power bill plunge on her Columbus home from $224 in June 2024 to $50 in June 2025 after her panels came online, and she says the added resilience eases her mind during storms.

Nonprofits are benefiting, too. Trees Atlanta had 140 panels installed on their headquarters last November in the pilot program; the rooftop array went live in March and is on track to save about $3,000 a year, the carbon equivalent of planting 28,000 trees over 25 years.

What’s next for Georgia BRIGHT …

Georgia BRIGHT’s other programs in the works include its Residential Solar Savings Plan, offering custom rooftop installs with no upfront cost and guaranteeing households at least 20% savings on day one after factoring in the modest monthly payments. Georgia BRIGHT is also developing Community Benefit Solar, which lets businesses, houses of worship, and apartment buildings go solar so long as they share part of the financial benefits – think grocery gift cards, help with utility bills, discounted daycare, or rent relief – with eligible neighbors for five years. Finally, a Utility-Led Community Solar initiative will send grants to local utilities so they can run shared-solar programs designed specifically for low-income customers.

These programs really make a difference in a state like Georgia, which doesn’t offer any other solar incentives.

… if the EPA doesn’t steal its money

The New York Times reported today that the Trump-led EPA is drafting letters to claw back the entire $7 billion Solar for All pot from 49 states, plus 11 nonprofit groups and Native American tribes. The grant money was awarded under President Biden’s 2022 Inflation Reduction Act. According to the Times‘ sources, the EPA plans to send termination notices this week, effectively erasing solar savings for nearly a million low-income families before the panels ever land on their roofs.

Legal groups are already gearing up for the fight. “If leaders in the Trump administration move forward with this unlawful attempt to strip critical funding from communities across the United States, we will see them in court,” Kym Meyer of the Southern Environmental Law Center told the Times.

If the EPA pulls the trigger on this cruel, senseless plan to steal solar from lower-income communities, it wouldn’t just kneecap Georgia’s new program – it would pull the rug out from under low-income solar projects nationwide. The fight over Solar for All is officially on. How about that energy emergency that Trump declared, eh?
