Solar Panels in Crest, CA.
Solar Panels for Crest homes, done by experienced San Diego County technicians. Dirty solar panels don't fail, they just quietly lose 10–25% of their output and most homeowners never notice because the utility bill creeps up slowly. The method to look for is deionized water (no mineral spots), a soft solar-specific brush (no scratches), and no detergents.
Why is solar panels different in Mountain San Diego?
Mountain arrays collect pine pollen in spring, oak leaves in fall, and occasional light snow dust. Spring cleaning catches pollen; fall cleaning clears leaves before winter production.

Does cleaning solar panels really matter?
NREL and independent studies put the production loss from dirty panels at 10–25% depending on tilt, location, and dust exposure. Over a year, that adds up to real lost electricity.
Will cleaning affect my panel maker's coverage?
Not when done correctly. Many panel makers prohibit high-pressure water, abrasive brushes, and solvents. Ask the pro you are matched with to use deionized water and soft brushes, and check your panel maker's cleaning guidance.
