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. From pv magazine Global Researchers […]
Solar pricing needs a reality check
Sustainable projects depend on prices — and suppliers — that hold up under compliance, delivery and long-term performance requirements. At RE+ in Las Vegas, one of the dominant themes was pricing across the solar supply chain. Numbers were being shared that sounded almost too good to be true and, in many cases, were. Some offers […]
Domestic content, TPO-readiness take center stage at RE+ 2025 solar and storage trade show
Booths across the show floor in Las Vegas, Nevada touted the occupants’ onshoring bona fides. Despite headwinds from shifting federal policy, the 2025 RE+ conference was nearly as big as ever. More than 37,000 attendees walked the halls of the Venetian Expo Center and Caesar’s Forum in Las Vegas during the event. One symbol of […]
U.S. grid-scale storage leaps 63%, residential storage 132%
The utility-scale energy storage sector added 4.9 GW in Q2, representing 63% year-on-year growth, while residential storage increased by 608 MW, said a report from American Clean Power Association and Wood Mackenzie. The United States had a record quarter for battery energy storage deployment in Q2 2025, adding 5.6 GW of installations, said a report […]
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. At RE+ 2025, SPR (solarpanelrecycling.com) highlighted the company’s steady expansion to streamline the processing of end-of-life PV panels. In his interview, […]
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. Utilities are backtracking on their climate commitments and giving more gas to fossil fuels, according to Sierra Club’s annual report that evaluates utilities on their transition […]
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. From pv magazine Global North Carolina’s provider of electrical balance of systems (EBOS), Voltage Energy, has launched two new pre-assembled wiring solutions for PV projects. The Lynx product is engineered for utility-scale […]
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. From ESS News US-based startup BESSt has launched a new redox flow battery technology that reportedly achieves 20 […]
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. A flexible interconnection option for distributed solar or storage in California that was long in the works has now taken effect. The option will enable projects […]
