Professional cleaning using deionized water and soft-bristle tools delivers the best results. This method removes dust, pollen, and salt without leaving residue or causing micro-scratches that reduce efficiency. Avoid harsh chemicals, abrasive materials, and cold water on hot panels to protect your warranty.

Yes. Dust, pollen, bird droppings, and coastal salt reduce solar output by 15-25% across San Diego County. Professional cleaning restores peak efficiency and typically pays for itself in 2-3 months through increased energy production. Regular maintenance also extends panel lifespan and protects your investment.

Costs vary by array size, location, and accessibility. Residential cleaning typically ranges from $100-300 per service, while commercial installations are priced per panel. Most property owners recover costs in 2-3 months through increased energy production. Request a custom assessment for accurate pricing.

Coastal properties need cleaning every 2-3 months due to salt air exposure. Inland areas require 3-4 annual cleanings, plus additional service after wildfire season. Spring pollen and fall dust create seasonal soiling that benefits from professional maintenance. Your specialist will recommend a schedule based on your microclimate.

No, when performed correctly. Vetted specialists use manufacturer-approved methods including soft-bristle tools, deionized water, and biodegradable agents that protect warranties. DIY cleaning with harsh chemicals or abrasive materials can void coverage. Always confirm your specialist follows warranty-safe protocols.

Most San Diego properties see 15-25% efficiency restoration after professional cleaning. Actual gains depend on soiling severity, panel angle, and location.

Vetted partners use deionized water and biodegradable cleaning agents that leave no harmful residue. Water usage is minimized through efficient application methods. These eco-friendly techniques protect both your panels and the environment while delivering superior cleaning results compared to harsh chemical alternatives.

DIY cleaning risks micro-scratches from improper tools, thermal shock from cold water on hot panels, and personal injury from rooftop access. Professional specialists have proper equipment, insurance, and training to clean safely while protecting your warranty. The efficiency gains typically justify the service cost.

Residential cleaning typically takes 1-2 hours depending on array size and accessibility. Commercial installations require longer service windows based on panel count.
