Thanks in large part to the recent influx of solar distributed energy resource (DER) generation, the California utility grid is becoming saturated much faster than anyone ever expected. Saturation in this context refers to the maximum solar capacity...

PV systems can incur undetected phantom losses, which reduce energy yield and economic performance. Aerial inspections, which capture IR and visible imagery, approach this problem from an entirely new vantage point—namely, from the air.

Owners, developers, bankers and O&M providers all want to know when it makes sense to clean a PV array to recapture revenue that it would otherwise lose due to soiled modules. It is difficult to assess soiling and to determine when to wash an...
