Five Puerto Rico reservoirs could host 596 MW of floating solar

Potential sites for solar in Puerto Rico include reservoirs, brownfields, closed landfills, fossil generating plants after closure, and transmission rights of way, determined analysis by the National Renewable Energy Lab.

Community solar increases energy equity, report finds

For the first time research looks at data about households adopting community solar along with policy that promotes outreach, and the results confirm that coalition efforts are beneficial.

Sunrise brief: ‘Misguided’ CPUC vote may derail California community solar

Also on the rise: Are false pretenses driving solar cell tariff case? Long-duration energy storage poised to outcompete lithium-ion batteries. And more.

Strategies to address thermomechanical instability of perovskite solar modules

A U.S. research team has investigated the thermomechanical reliability of metal halide perovskite (MHP) modules and cells in an effort to identify the best strategies to improve their stability under thermomechanical stressors. The scientists discussed, in particular, film stresses, adhesion of charge transport layers, and instability under light and heat.

Sunrise brief: Battery energy storage tariffs tripled; domestic content rules updated

Also on the rise: Bringing lithium-sulfur batteries closer to commercialization. Largest solar project in Wyoming moves forward. And more.

Perovskites move into production

Perovskites remain a great hope for the future of the solar industry, once the possibilities of tunnel oxide passivated contact (TOPCon) and heterojunction PV have been exhausted. A look at the latest perovskite research shows that industry optimism is built on a strong foundation.

Solar peaks at 123% of grid, supplies 31% of California’s April electricity

The Golden State set multiple clean energy records in April, with solar power increasingly dominating the grid, supported by robust energy storage solutions.

Research shows repaired PV modules can perform with acceptable losses

A research group has demonstrated the technical feasibility of using repaired solar modules with satisfying results. It also warned, however, that there is an urgent need to define a protocol for evaluating the features of a “viable” repaired panel.

Renewables must triple by 2030 to hit net-zero by 2050, says BloombergNEF

BloombergNEF says in a new report that solar and wind must drive most emissions cuts before 2030 to stay on track for net-zero by 2050. Its net-zero scenario targets a combined solar and wind capacity of 31 TW by 2050.

Strong state solar policies boost adoption of distributed energy

Of the 29 GW of solar installed in the U.S. in 2023, 31% was distributed solar, according to the Institute for Local Self-Reliance.
