Pre-clean Check
Know where your array loses power - a focused check estimates soiling loss, flags shading, and recommends next steps.
What We Do
Covers soiling loss estimates, shading notes, and basic on-site output checks of array sections.
Estimate of energy loss from dirt and shading to inform cleaning scope.
On-site comparison of expected and measured panel output per section.
Why San Diego Solar Panel Cleaning
Small amounts of dirt, shading, or access issues can mask real output losses and lead to unnecessary full-array washes.
Dust from foot traffic and pollen reduce glass clarity in Old Town, cutting production by a few percent or more if left unchecked.
Partial shading across array sections lowers local output and skews system data, making it hard to find faults without section checks.
Without targeted evaluation owners often schedule full-array cleaning that adds cost and roof access risk without proven production gains.
On-site checks compare expected vs measured output to produce a percent estimate of loss attributable to dirt and shading.
We identify which array sections need washing so you avoid full-array cleans and reduce labor, water, and roof access time.
