We stand behind our work with documented output recovery guarantees:
Studies show solar panels in Southern California lose 15–30% of output to soiling between cleanings. A professional SAGEFLOW™ clean recovers this immediately. For a 20-panel system, that's $400–$900+ in recovered annual electricity value.
Quarterly (every 3 months) is recommended for Southern California due to vehicle exhaust pollution, wildfire ash, and hard water mineral deposits. Our SAGEFLOW™ protective coat resists re-soiling for 3–5 weeks, but quarterly service keeps output maximized year-round.
Yes. SAGEFLOW™ is non-corrosive, non-abrasive, pH mildly neutral, and safe for all photovoltaic panel types. It's compatible with all major manufacturer warranties and does not damage anti-reflective coatings.
