French PV system installer Sunbooster has developed a cooling technology for solar panels based on water. It claims its solution can ramp up the power generation of a PV installation by between 8% and 12% per year. The solution consists of a set of pipes that can surround a rooftop PV system or ground-mounted plant. The pipes are used to spray a thin film of water onto the glass surface of the modules. The company's solution is a patented pipe with a number of very small holes, so special installation skills are required. Stored rainwater is pushed into a ramp at the edge of the panels. Water then flows onto the surface of the modules and immediately lowers the temperature. “The materials used to build the pipes have been chosen based on their quality, reliability and durability,” Pipes are UV-resistant and drilled with holes – their number and size are defined by our design and engineering office in respect of our patents.”The water only spreads across the glass surface of the panels and does not touch any plastic parts, such as the backsheets or other components. “It can be considered in the same way as rain, and for this reason it does not affect the warranty of the modules,” The system is set in motion by a temperature sensor which triggers the water spread when ambient temperatures exceed 25 C. Although the water may have some influence on the modules’ light absorption, this is fully compensated by the increase in power yield that can be achieved by preventing temperatures from surpassing 30 CThe cooling systems collect the water from a rainwater tank. And after the water is used, it can be recycled, filtered, and stored again. “Our Sunbooster solution works in closed circuit and doesn’t need additional water,”
