As residential solar installers face the end of the Section 25D solar tax credit, they must grapple with how to reduce costs, work with new financing models, and build systems that provide new ways to capture long-term value through grid interactivity.

Revenues for ancillary services have fallen 90% since 2023. An Enverus report says market saturation is driving operators to seek other strategies.

The U.S. Consumer Product Safety Commission (CPSC) says EcoFlow is recalling about 25,030 Delta Max 2000 power stations after six reported fires caused more than USD 850,000 in property damage.

Fullmark Energy completed the $46 million Investment Tax Credit transfer for its operational 125 MW / 290 MWh Redwood Projects energy storage portfolio in California.

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.

The company produces batteries and inverters for residential and commercial applications. It secured funding for a potential U.S. manufacturing facility, pending definitive agreements.

Energy storage in urban areas make strong use case for non-flammable flow batteries.

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 U.S. Trade Representative has extended the exclusion of 178 items from the Section 301 import tariffs that were put in place by the prior administration in 2024. The still standing tariffs include a 50% increase on solar cells

A coalition of 18 California legislators has formally urged the California Public Utilities Commission (CPUC) to enforce regulations under “Rule 21” regarding the interconnection of customer-sited solar and energy storage systems.

Offered primarily as a 10 MW unit, the new product is also available in a 5.5 MW version for customers with specific requirements.

pv magazine USA spotlights news of the past week including market trends, project updates, policy changes and more.

A report from the International Renewable Energy Agency (IRENA) notes that while it is still uncertain whether sodium-ion batteries will become a disruptive alternative to lithium-ion technology, they could offer significant cost-saving opportunities in applications such as electric vehicles and large-scale energy storage.

TITAN Containers’ ArcticStore Horizon have a solar-grid power management system and cleaner refrigerants.

A study from Grid Strategies and ACORE finds evidence that priority transmission access offered by three grid operators has yielded generating portfolios “heavily weighted” to thermal resources. The study favors transmission planning followed by recruitment of projects that can use planned transmission capacity to enter the interconnection queue. A limited non-discriminatory “fast path” could meet near-term reliability needs.

Solar developer Plenitude will validate Swift Solar’s 28% efficiency perovskite-silicon tandem technology in a utility-scale project.

A research team led by Washington State University has developed a cloud-based system for trading and sharing energy from solar panels and batteries within a neighbourhood. The concept displayed potential energy cost savings of around 12% over a five-day test period.

A study finds combining wind and solar leverages their alternating peak periods, significantly boosting total generation capacity while providing a constant, predictable power curve critical for grid integration.
