Solar Panel Cleaning in North Park, San Diego
We clean rooftop solar arrays across North Park using deionized water and soft brushes, no detergent and no high pressure. Most 15 to 25 panel systems take under two hours and run $150 to $300. Clean panels in North Park typically recover 5 to 15 percent of lost output after months of dust and bird droppings.

Why North Park Panels Get Dirty Fast
North Park sits inland enough to trap dust but close enough to the coast to catch the marine layer. That combination leaves a film that dries into a haze on the glass.
We see it most on the older Craftsman homes near 30th Street and University Avenue, where mature trees drop pollen and shade lets grime hold longer. Bird droppings are the bigger problem though. They bake onto the panel in the afternoon sun and create hot spots that drag down a whole string.
How We Clean Them
We do not use soap. We run deionized water through a soft-bristle brush on a pole so we can reach most single-story and two-story roofs from the edge without walking the array. Deionized water dries without spots, so there is no residue left to attract more dust.
On tile roofs common around North Park we stay off the tiles wherever we can. They crack under foot weight, and a cracked tile costs far more than the cleaning. When we do need roof access we use standoff anchors and spread the load.
What It Costs
A typical North Park home with 15 to 25 panels runs $150 to $300 depending on pitch, height, and how much bird mess has built up. Ground-mount and larger arrays we quote after a look. We check the inverter reading before and after so you can see the output change, not just take our word for it.
We also handle pressure washing and soft washing in the same neighborhood, so a lot of North Park customers add a driveway or stucco wash to the same visit. See our full solar panel cleaning page for details, and reach out for a free quote.
