Solar power

The largest solar farm in Ohio, Fox Squirrel Solar, is now fully online and delivering clean electricity to the PJM grid.

Puerto Rico kicked off 2025 with a harsh reminder of its fragile power grid. On New Year’s Eve, nearly the entire island – 90% – lost electricity, leaving over 1.3 million customers in the dark during holiday celebrations. Power was restored on January 1, but the blackout underscored an urgent need for reliable energy solutions.

In a move to help bolster Puerto Rico’s grid resilience, Convergent Energy and Power secured a conditional commitment from the US Department of Energy (DOE) Loan Programs Office for a massive solar and battery storage initiative in December. The DOE’s backing includes up to $559.4 million in loan guarantees, paving the way for Convergent to install both solar and standalone battery systems across the island.

A new study published in the journal Renewable Energy uses data from the state of California to demonstrate that no blackouts occurred when wind-water-solar electricity supply exceeded 100% of demand on the state’s main grid for a record 98 of 116 days from late winter to early summer 2024 for an average (maximum) of 4.84 (10.1) hours per day.

Trina Solar has sold its Texas solar panel factory as the US scrutinizes Chinese companies cashing in on Inflation Reduction Act tax breaks.

The Inflation Reduction Act (IRA) is a “free electric bank account with your name on it.” It’s packed with rebates and tax credits that help Americans purchase everything from EVs to solar and electrical appliances to heat pumps. Check out this easy-to-use IRA savings calculator from Rewiring America that tells you what you get – and when.

Renewable energy is now over 30% of total US utility-scale electrical generating capacity and on track to reach 37% by the end of 2027, according to data in two new end-of-the-year reports just released by the Federal Energy Regulatory Commission (FERC) and the US Energy Information Administration (EIA) and reviewed by the SUN DAY Campaign.

A coal plant in South Texas will shut down and convert to a solar + battery electricity generation facility, with the help of a $1.4 billion grant from the US Department of Agriculture meant to help clean energy while saving rural jobs.

At 5,228 meters (17,152 feet) above sea level, phase two of the world’s highest-altitude solar plus storage project has begun generating power, setting a new benchmark for renewable energy in extreme conditions.

Ampion Renewable Energy has brought five community solar farms in Maine online, adding nearly 25 megawatts (MW) of clean energy to the grid and generating over 28 million kilowatt-hours (kWh) of electricity annually.

Walmart is working with community solar developer and operator Nexamp to build 31 community solar farms across the US.

Cambridge, Massachusetts, has signed the largest-ever virtual power purchase agreement (VPPA) by a US city to help build a utility-scale solar farm in Illinois.

The Solar Energy Industries Association (SEIA) has unveiled a “Top 10” solar and storage priorities list for President-elect Trump and the 119th Congress – here’s what it wants.

Nextracker just set a milestone in US clean energy manufacturing: It has delivered the first-ever solar trackers expected to meet 100% domestic content requirements under the Inflation Reduction Act (IRA).

Commercial rooftop solar developer Solar Landscape secured a record-breaking $847 million in 2024 to fund its largest-ever portfolio of commercial rooftop solar projects. This windfall will finance over 200 US installations and bring clean energy to the equivalent of more than 50,000 homes.

One of the US’s largest solar + battery storage projects is now online in Mojave, California. Arevon Energy’s Eland 1 Solar-plus-Storage Project combines a 384-megawatt (MW) solar farm with a 150-MW/600 MWh battery storage system.

The US’s largest proposed solar and storage project, the 2.4 gigawatt (GW) Sunstone Solar, just got the go-ahead from Oregon regulators.

The US has imposed new anti-dumping tariffs on solar panels imported from Southeast Asia, tightening restrictions on Chinese manufacturers accused of using these countries to avoid fair trade rules.

The US is on track for another record-breaking year for solar, with over 32 gigawatts (GW) of utility-scale installations expected in 2024, according to the inaugural Solar Market Monitor from the American Clean Power Association (ACP) and S&P Global Commodity Insights.

Singapore-headquartered Maxeon Solar Technologies (Nasdaq: MAXN) is restructuring to focus exclusively on the US market, but it’s put its $1 billion Albuquerque solar cell factory on ice.

During the first three quarters of 2024, renewables increased their output by almost 9% year-over-year, and solar is still leading the charge, reports the US Energy Information Administration (EIA).
