Why annual GHI maps can mislead solar risk assessments
According to SolarGIS, single-year irradiance anomalies shouldn’t be used to reveal long-term trends or structural shifts in solar resource risk.
How battery deployment in the Eastern U.S. could scale as in Texas and California
A study led by two energy lawyers documents the causes of “lagging” battery energy storage deployment in the Eastern U.S. and recommends 15 policy solutions that could help scale BESS deployment.
Rethinking solar and storage ROI: Beyond old efficiency assumptions
Legacy solar models focused on daytime production, but the shift to battery-driven self-consumption is creating a performance gap that puts long-term ROI at risk.
When the sun sets, batteries rise: 24/7 solar in California
On February 1, 2026, California’s batteries bridged the solar gap with seamless precision. After discharging through the night until sunrise, they spent the daylight hours charging, then pivoted back to exporting power well past midnight—effectively sustaining the state on solar energy for a full 24-hour cycle.
Battery storage management keeps solar in the energy mix
FlexGen’s Jason Abiecunas describes how BESS is at the heart of reliable new capacity.
“Made in the USA” batteries might still fail FEOC
Even U.S.-assembled storage systems can carry FEOC exposure via upstream ownership and materials processing, which is forcing developers to rethink diligence, serviceability and replacement strategies.
People on the move: SunPower, SEIA and more
Job moves in solar, storage, cleantech, utilities and energy transition finance.
PowerBank revenue climbs to $22.3 million, announces solar-powered space-based AI computing
PowerBank Corporation, a North American developer and operator of solar and battery energy storage projects, reported $22.3 million in revenue for the first half of its fiscal year and secured new credit facilities to expand its project pipeline.
Trump signals rollback on 50% steel and aluminum tariffs: What it means for solar
The pivot toward “targeted” metal duties could offer a vital pressure-release valve for a solar industry struggling with historic hardware price spikes.
Inside Portland’s experiment that turned interconnection limits into a microgrid blueprint
A market-rate, subsidy-free solar-plus-storage microgrid in downtown Portland highlights how grid-forming buildings can overproduce clean power, island during outages and work around strict interconnection limits.
