Find where solar cleaning could pay

SolarSoiled identifies rooftop solar and helps assess where cleaning could deliver a financial return. It brings together estimated system size, seasonal soiling, and screening for persistent residue to prioritize properties for closer assessment. Explore the public map, compare cleaning scenarios, or partner with us to evaluate your service area.

These estimates separate four distinct jobs: detecting arrays, estimating system size, screening for persistent residue, and estimating energy recovery. Regular Soiling comes from local weather records, while Persistent Soiling stays a conditional scenario until site evidence supports a loss percentage. The dollar figures use Santa Cruz rainfall and electricity assumptions; system size is estimated from the detected roof geometry.
