California allows flexible interconnection for distributed solar, storage to avoid grid upgrades
California is the first state to enable distributed solar or storage projects to use flexible interconnection, but the hardware required to flexibly control output may not yet be available.
Startup unveils zinc-polyiodide 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.
Voltage Energy releases two wiring solutions for solar 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.
Utilities pump the brakes on climate commitments while giving more gas to fossil fuel
Most utilities failed Sierra Club’s annual report because they are building and maintaining too many fossil fuel plants and too few clean energy projects to keep up with demand.
SPR shortens distance between solar sites and recycling facilities
The company has expanded rapidly to bring its services to all 50 states in the US and is already recycling end-of-life panels at scale, according to Brett Henderson, the CEO and co-founder of SPR.

Sustainable projects depend on prices — and suppliers — that hold up under compliance, delivery and long-term performance requirements.
Scientists break Shockley-Queisser efficiency limit for silicon solar cell in experiment
A Chinese-US research group claims to have achieved a power conversion efficiency of over 50% in an n-type single-junction solar cell by inhibiting light conversion to heat at extremely low temperatures. The result was achieved at temperatures of 30-50 Kelvin, which are a few tens of degrees above absolute zero.
