Q. How would I clean installed solar panels out in the field using minimum amounts of water?
A. For field cleaning solar panels and modules, we recommend using Liquinox® Critical Cleaning Liquid Detergent. This is a liquid concentrate that would be used at a 1% solution (1.25 oz/gal, or 10 mL/L). Liquinox is not harmful to discharge onto the ground in an agricultural setting, yet is a powerful emulsifier of organic and oily residues found in your everyday environment.
Liquinox detergent will not attack glass or aluminum substrates. We recommend developing a cleaning procedure that allows you to spray on the 1% Liquinox solution using irrigation water (possibly use a garden sprayer or backpack sprayer). Allow the sprayed on solution to sit for as long as is practical without excessive evaporation. Do some scrubbing with a light plastic brush to get any really tough spots loosened up. Rinse thoroughly with irrigation water, then if practical, do a final rinse. This basic procedure for cleaning solar panels will leave them clean and residue -free.
