The Solar Energy Industries Association (SEIA) has released an analysis indicating that new federal policies targeting renewable energy are placing a significant majority of planned solar and battery storage capacity in Texas at severe risk.

About 20% of planned capacity additions reported delays in Q3 2025, down from the 25% of projects reporting delays in Q3 2024.

Puerto Rico has reached 1.3 GW of residential solar and 185,000 residential batteries, with Wood Mackenzie expecting three more GWh of residential storage by 2029. Utility-scale solar and storage projects are gearing up, as described by an attorney with McConnell Valdés.

Bechtel will manage the construction of Doral Renewables’ solar and battery storage facility in Texas, underscoring the shift toward co-located storage as the standard for ERCOT projects.

The deal for the new project in Arizona comes from a lending consortium, while Plus Power secures new funding to expand its New England footprint.

First Solar has selected Gaffney, in Cherokee County, South Carolina, as the site for its fifth U.S. module manufacturing facility. The company will invest approximately $330 million in the project.

Electrical component and system manufacturer Socomec will invest nearly $10 million in a new manufacturing and distribution facility specializing in low-voltage energy performance solutions.

mPower Technology Inc. has switched on an automated production line for its silicon solar panels designed for space missions. The site currently has an annual capacity of 1 MW, set to double by the middle of 2026.

The largest U.S. solar manufacturer is temporarily scaling back production and its workforce after shipments of necessary components were held up at U.S. ports, citing enforcement of the Uyghur Forced Labor Prevention Act (UFLPA).

The U.S. solar industry has entered a high-stakes era where policy compliance and supply chain integrity are just as critical as project economics. Day 2 of pv magazine USA Week 2025 dives into this complex environment, where federal trade restrictions and the push for domestic manufacturing are radically reshaping how solar projects are financed and built.

Renewable energy firm PowerUQ advocates for the use of Uncertainty Quantification (UQ) in solar project analytics to combat the widespread issue of performance shortfalls. By incorporating a wider range of variables and providing probability scenarios like P50 and P90, UQ aims to make solar generation forecasts more useful and accurate over a project’s long lifespan.

PJM said it agrees with many of the recommendations for speeding transmission interconnection made by the nonprofit group RMI, and reported it has completed 600 interconnection studies in less than 22 months under its current interconnection study process. Even so, a GridLab report says PJM would have substantially lower capacity costs next year if a modest portion of renewable and storage projects in PJM’s queue had been set to reach operation by then.

As universities expand outdoor learning, off-grid solar furniture is emerging as a new class of campus infrastructure.

The International Renewable Energy Agency (IRENA) says solar is the only renewable energy technology where current investment levels are approaching the annual average needed through to 2030 to align with its 1.5 C pathway.

More than 50 House Republicans are urging the Trump administration to prohibit the import of solar and battery energy storage inverters manufactured by companies from “foreign entities of concern” (FEOCs).

U.S. researchers have developed a sodium-ion pouch cell that operates reliably at temperatures as low as –100 C. The battery was tested with simulated and real renewable energy sources, including wind and solar, and maintained stable performance in both laboratory and field conditions.

Engineers at the Massachusetts Institute of Technology say their polymer coating could be used to protect photovoltaic modules, due to its impermeability to gases. The team has demonstrated that a 60-nanometer-thick film can extend the lifetime of a perovskite crystal by several weeks.

A US research team has developed all-solid-state sodium batteries that retain performance down to subzero temperatures. The systems utilize a special chloride-based solid-electrolyte-coated cathode.

A team of researchers in Canada has developed the Jericho Open Resistive Data Logger—an open-access photovoltaic (PV) monitoring platform that integrates data acquisition and processing hardware, a software framework, and a comprehensive sensor array. Designed primarily for agrivoltaic applications, the system has a total estimated cost of around $2,000.

Incoming governors in New Jersey and Virginia campaigned on broad clean energy platforms, while Advanced Energy United sees underused points of interconnection as the best solar and storage opportunity in Virginia.
