As States Legalize Plug-In Solar, Safety Standards Race To Catch Up

As States Legalize Plug-In Solar, Safety Standards Race To Catch Up

Uncategorized / By

On Tuesday, New Jersey Gov. Mikie Sherrill signed a bill designed to make it easier for residents to generate their own electricity by using small solar systems that plug directly into a household outlet. “Balcony solar is the ultimate win-win,” Sherrill said after plugging in a solar panel at the bill-signing ceremony. “It’s accessible, affordable, […]

FRANK LASEE: Congress must act to eliminate subsidies for wind and solar grid batteries

FRANK LASEE: Congress must act to eliminate subsidies for wind and solar grid batteries

Uncategorized / By

Congress did something right last summer. The One Big Beautiful Bill ended the open-ended tax credits for wind and solar. A project must break ground by July 4, 2026, or be operating by the end of 2027, or it gets nothing. Yet Congress left a gaping loophole. It preserved the same rich subsidy for grid

Solar seasonal storage system achieves 4.1 heat pump COP in greenhouse heating

Uncategorized / By

South Korean researchers have demonstrated a small-scale solar seasonal thermal storage system integrated with heat pumps for greenhouse heating over three years. The system achieved average thermal storage efficiency of 55.1%, while the dual-source heat pump recorded an average COP of 4.1. A research team from South Korea’s Korea Institute of Energy Research (KIER) has

Perovskite solar cell based on seed crystals achieves 23.51% efficiency

Perovskite solar cell based on seed crystals achieves 23.51% efficiency

Uncategorized / By

Researchers have developed a seed-assisted crystallization strategy to produce pure α-phase FAPbI3 perovskite without conventional chemical stabilizers. The resulting device reached 23.51% efficiency and retained 99% of its initial performance after 3,000 hours of unencapsulated operation.
