In 2014, two solar groups released a report which found that only around 3,750 schools in the US – out of a total of around 130,000 – generate electricity from solar panels. But this number is growing.
According to the fourth edition of the Brighter Future report, published last week by the clean energy nonprofit Generation180, the number of US schools using solar energy has more than doubled in the past seven years, reaching around 8,400 by the end of 2021. These so-called “solar schools” now account for nearly 1 in 10 public, independent, and charter K-12 schools, serving more than 6 million students nationwide.
Tish Tablan, program director of Solar for All Schools Generation180 and lead author of the report, called the number an “amazing milestone.” As some schools are building new solar panels on the roof and on the ground, others subscribe to community solar programs. In some cases, solar panel schools generate enough electricity to sell to their communities. Since 2015, total solar power in U.S. schools has almost tripled to 1,644 megawatts, enough to meet the electricity consumption of all households in a city the size of Boston, Denver and Washington.
California is at the forefront of the package; The Golden State has both the largest number of solar schools and the largest solar capacity. It ranks fourth in the percentage of schools that have solar energy, ahead of Connecticut in Washington state and Hawaii alone, where a full 40 percent of schools have adopted solar energy. Other states are making huge gains – between 2019 and 2021, Washington’s solar power more than eightfold, while Wisconsin, Illinois, Arkansas and Virginia at least doubled their installed solar capacity.
According to Tablan, much of this growth was made possible by third party financing models such as power purchase agreements or PPAs. Under these contracts, developers pay for the installation and operation of solar panels, while schools buy electricity for a certain period of time. Developers benefit because their deals allow them to take advantage of federal tax credits and provide a stable source of income.
In the case of schools, the agreements could cut utility bills by thousands of dollars and remove the initial costs of a solar installation – something that, according to the Generation180 report, was “critical” to solar expansion beyond the richest school districts. As of 2021, the report states that 47 percent of solar-powered public schools are eligible for federal funding under the Title I Schoolwide Program, indicating that at least 40 percent of their students come from low-income families. (As of 2019, 57 percent of all public schools nationwide are eligible for such funding.)
For example, at Denver Public Schools, Colorado, PPAs with several solar power companies have helped a school district of 90,000 students install 9 megawatts of solar power in 50 schools, at least 21 of which have Title I Schoolwide. As a result, the county achieved annual emissions reductions equivalent to the removal of 2,175 gasoline-powered cars from the roads.
As an added bonus, schools in Denver use solar panels to teach students about renewable energy. This summer, Denver public schools partnered with a solar power plant nonprofit to offer high school students hands-on engineering and career guidance – a form of early career training for aspiring electrical engineers. One of the students interviewed for the Generation180 report, Kimberly, said the program “opened my eyes and introduced me to careers I didn’t know existed.”
Despite advances in schools, Generation180 insists that there is still a long way to go, as about 90 percent of US schools still do not have solar panels. “There is still a long way to go to the goal of 100% clean energy,” the report reads, “and the speed and scale of the climate crisis require us to react faster than ever.” According to the organization’s estimates, moving all US K-12 schools to 100% of solar energy would eliminate 60 million metric tons of carbon dioxide emissions annually – roughly as much as the annual climate pollution at 16 coal-fired power plants.
Tablan says more PPAs could help push the needle forward, and a policy reversal in six states – mostly in the south – that restricts these third-party financing options could have a particular impact. Federal funding from last year’s Inter-Party Infrastructure Act and this year’s Inflation Reduction Act may also be helpful; Together, the regulations include hundreds of millions of dollars in grants to modernize schools’ energy systems and reduce climate pollution, as well as an extended tax break to help schools compensate for new solar and battery projects.

Does solar energy work at night? In short, the answer is yes. The solar energy is captured and then stored in your system, allowing it to be used after sunset.
Do solar panels still work on cloudy days?
Solar panels can use direct or indirect sunlight to generate energy, although they are most effective in direct sunlight. Solar panels will continue to function even when light is reflected or partially blocked by clouds. Rain actually helps keep the panels running smoothly, washing away all dust and dirt.
How do solar panels work when there is no sun?
