Solar Panel Cleaning in Encinitas
We clean solar arrays from Leucadia down to Cardiff, and the coast leaves its mark on every one of them. Salt drifts off the water and settles on the glass as a fine haze. It does not rinse off with rain. It bakes on.
Last month we cleaned a 24-panel array off Quail Gardens Drive. The owner had not touched it in three years. Output was down close to 14 percent.
Why coastal arrays in Encinitas lose output
Two things work against panels here. Salt film from the marine layer, and the morning damp that lets dust and pollen stick instead of blowing off. Homes up in Olivenhain trade salt for dust off the dry hills, but the result is the same. A dull layer on the glass that costs you watts.
Rain is not a cleaning. It spreads the grime into streaks and dries it back down.
How we clean them
We never put pressure on a panel. High pressure forces water past the seals and can void the manufacturer warranty. Our crew runs deionized water through a soft brush on a water-fed pole, working from the roof edge or the ground where the pitch allows. Deionized water dries with no spots, so nothing is left behind to pull in more dust.
We check inverter output before and after. Most Encinitas arrays gain back 8 to 15 percent.
What it costs
Most residential arrays in Encinitas run $150 to $400 depending on panel count, roof pitch, and access. Ground-mount and tile-roof setups in Encinitas Ranch take longer, so they sit at the upper end. If your HOA limits roof work hours, tell us and we schedule around it.
