A thermal camera mounted on a drone finds hot spots, bypassed diodes, and cell-level defects in 20 minutes, work that takes a hand-held inspector half a day. We deliver a full thermal map, a marked photo of every problem panel, and a written report with module IDs ready for warranty claims..

El Cajon: El Cajon is one of the hottest residential zones in San Diego County. 100-115°F summers, hard-water sprinkler overspray on aging tract stock, I-8 corridor traffic film, and post-fire ash from East County wildfire events drive quarterly cleaning as the working baseline. Arrays here lose production fast without consistent cadence.
