Solar Panel Cleaning in Rancho Del Rey
Soiling and output vary from system to system. Check visible buildup, panel cleaning instructions, and monitoring data under similar weather conditions. Cleaning isn't guaranteed to cover its cost, and a thermal image isn't an electrical diagnosis.
Dirt and debris can block sunlight, but the effect varies with the amount of buildup, panel tilt, rainfall, shading, and equipment condition. We don't have a verified typical loss figure for San Diego homes. Compare monitoring data under similar weather conditions before and after cleaning rather than expecting a fixed percentage gain.
Why older systems benefit most
Thermal images flag unusual surface temperatures, not confirmed faults or warranty eligibility. Your installer or manufacturer may need visual checks, electrical testing, or other imaging to identify the cause and decide next steps.
