Reduce Derating due to soiling with PURETi

Solar panels, film and mirrors all soil, blocking light and Solar panels, film and mirrors all soil, blocking light and locking in efficiency-draining heat. Dirty panels can reduce PV solar output by 5%-30%. Thermal solar can lose up to 40%. Maintenance on solar panels is never done often enough because it is often difficult to do and you don’t want to risk damaging the equipment.

PURETi is a cost-effective solution to the cleaning challenge. PURETi uses light energy to clean, saving water, energy and labor costs in maintenance, and more than paying for itself though improved output. Panels can be treated prior to application or inline at the time of the next cleaning.

PURETI’s invisible coating blocks less than 1% of light transmission. It more than offsets that minor loss through keeping the panel cleaner longer, and it seems to keep PV panels about 2 degrees cooler, too. A single application lasts for 5 years. For about $0.10 to $0.15 per square foot of product cost (initial cleaning and labor not included), you can get more out of your solar investment for years to come.
