US government lab sees utility scale solar fleet degrading faster than projected at 1.2% a year, while newer and larger plants are degrading at only 0.7% a year. Older plants appear to be getting repowered in year seven, yielding lasting performance increases.

Also on the rise: 300MW Bighorn Solar Project is complete. To achieve DOE’s goal, we need 700% more community solar in the next four years. MIT scientists develop PV cleaning system based on electrostatic repulsion. Solar drone data assessment shows rise in PV anomalies. Kentucky utility adds more solar as Solar Shares Program gains customers.

Over 20GW of solar array aerial visual data was processed by RaptorMaps, and roughly 2.6% of capacity was found to have anomalies that affect power production.
