US installs 14.5 GW of large-scale solar in H1
Solar represented 75% of US grid-capacity additions in the first half of 2025, followed by wind and natural gas, according to new data from the US Federal Energy Regulatory Commission (FERC).
SEIA unveils policy agenda to expand US solar, storage and grid reforms
The Solar Energy Industries Association (SEIA) has unveiled a new policy agenda calling for US grid reforms, domestic supply chain investment, and wider solar and storage deployment to meet surging US power demand.
US residential solar hits record-low $29,000 before incentives
US residential solar averaged a record-low $29,000 before incentives in the first half of 2025, while loan rates rose to 7.5% as demand softened, says EnergySage.
All back-contact perovskite solar cell designs at a glance
Scientists from Japan, Saudi Arabia and the United States have investigated existing back-contact perovskite solar cell architectures and have proposed a strategy to help reach commercial production.
New hail test aims to more accurately measure solar panel resilience
A new test curve for determining solar panels’ breaking point from hail uses a broader spectrum of impact energies and testing products.
Finetuning 2D Dion-Jacobson perovskites for photovoltaic applications
Canadian and U.S. researchers have investigated applying pressure to a 2D hybrid organic-inorganic perovskite to tune the optical and electronic properties to suit photovoltaic applications, light emitting diodes or other semiconductor devices.
New deep learning tech for PV inverter fault diagnosis
A team of scientists in the United States has combined both spatial and temporal attention mechanisms to develop a new approach for PV inverter fault detection. Training the new method on a dataset created in MATLAB/Simulink, the group has compared it to a series of other data-driven and statistical-based methods and has found accuracy reached 97.35%.
Americans back solar tax credits as civic duty, carbon pricing tool
The American public has shown a strong willingness to fund solar and other renewable energy projects through tax credits, largely because voters trust directed infrastructure funding more than open-ended government revenue pools.
