California replacing nuclear with solar plus storage
Clearway Energy has secured financing for the 200 MW Luna Valley Solar & Storage facility and the 113.5 MW Dagget energy storage project in California. These projects have signed PPAs that are part of a collection of projects being developed across the state intended to replace the potentially retiring Diablo Canyon Nuclear Power Plant.

A path to 20 GW of distributed solar in New York
Accelerating deployment of rooftop and community solar with supportive policies would help New York meet its goal of 70% renewable power by 2030 at lower cost, says a solar trade group.
Bigger is better as module makers power ahead
Larger wafer and module sizes have had a profound influence on module power output in recent years but standardization appears to have taken hold, with no further increases evident in module data, according to Molly Morgan, a senior research analyst at Exawatt, which is now part of the CRU Group.
Perovskite-CIGS tandem solar cells have technical potential to achieve 26.69% efficiency
A Dutch and U.S. research team performed optical and electrical simulations to understand loss mechanisms in two terminal (2T) tandem cells based on perovskite and commercially available copper-indium-gallium-selenide (CIGS) cells, and subsequently established a roadmap to increase efficiency via four key modifications.
New model to identify optimal power sizing ratio for solar inverters
Researchers in Malaysia have proposed a new approach to identify the optimal power sizing ratio to balance PV energy capture with inverter costs. The calibrated model is said to accurately reflect the relationship between inverter efficiency and real-world system behavior.
