US community solar likely peaked in 2024, says Wood Mackenzie
Wood Mackenzie says global solar installations fell 36% in the first half of 2025 and are set to contract 12% annually through 2030.
New control strategy for grid-forming inverters
Researchers in the United States have created a droop control strategy for grid-forming inverters that purportedly improves power system frequency stability. By using an exponential active power–frequency relationship, the novel technique optimizes the use of available headroom, reduces frequency deviations, and enhances overall grid resilience.
Zombie apocalypse-ready solar-plus-storage kit
JDEnergy introduced its eBlock 100C, eStation MV-6880, combined control systems, and the milestone deployment of its 20,000th energy storage block.
California enables flexible interconnection for solar and storage
California has introduced a flexible interconnection option allowing distributed solar and storage projects to connect without waiting for costly grid upgrades, though the required control hardware is not yet widely available.
Solar Servicing to acquire insolvent Mosaic
Solar Servicing LLC, a unit of Forbright Bank, will acquire insolvent Mosaic, with no plans to issue new loans but continued support for existing borrowers.
Voltage Energy releases two wiring solutions for PV projects
The US-based electrical balance of systems provider stated its new products are designed for utility-scale projects and the mid-capacity range. Both systems are IP68-tested.
US grid-scale storage leaps 63%, residential 132%
A report from the American Clean Power Association (ACP) and Wood Mackenzie indicates the utility-scale energy storage sector added 4.9 GW in the April-to-June quarter, representing 63% year-on-year growth, while residential storage increased by 608 MW.
US solar pricing needs a reality check
Sustainable projects depend on prices – and suppliers – that hold up under compliance, delivery and long-term performance requirements.
U.S. startup unveils zinc-polyiodid redox flow battery with energy density of 320 Wh/L
BESSt announced that its new redox flow battery technology delivers 20 times the energy density of conventional vanadium flow storage systems. The battery is based on a zinc–polyiodide redox flow chemistry developed by the Pacific Northwest National Laboratory.
Peak Energy announces operation of first large-scale sodium ion battery in US
