How fast can you get to El Cajon for drone inspection?

How does El Cajon's climate affect this service?
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.. East County drone inspections during summer get the cleanest thermal data, high irradiance loads panels enough to expose any defect immediately..
Can you fly during the day?
Yes, thermal anomalies actually show better in midday sun under load. The pro schedules between 11am and 2pm with at least 600 W/m² irradiance for accurate results.
What does a hot spot mean for my panel?
A hot spot usually means a cracked or shaded cell that's drawing power from the rest of the panel. Mild hot spots reduce output a few percent. Severe ones can permanently damage the panel and create fire risk. Most are warranty-replaceable if caught early.
