Pyron Solar has made a major breakthrough in the field of concentrated photovoltaics (CPV), after a prototype for its floating power system posted output figures nearly 20% higher than those of its commercial rivals.
“The synchronization of our modules to the daily and seasonal movement of the sun and the cooling and balance advantages delivered by our floating power-production arrays demonstrate an output-per-cell improvement of more than 19% over other commercially available CPV systems for utilities and commercial applications,” Pyron Solar’s president, Stephanie Rosenthal, said.
Generating high concentration levels while also maintaining low cell temperatures is one of the major dilemmas facing CPV project developers. Pyron's proprietary system is suspended in and cooled by water, enabling cells to produce up to 20W per cell while being maintained at relatively low operating temperature. Testing was carried out over a five-month period and under contract to San Diego Gas & Electric.
“The results show that because the cells are cooled and balanced by their water environment, multi-junction cells perform at an optimal performance level. We are very encouraged to come closer to our goal of delivering electricity for less than US$0.10 per kWh before incentives,” Rosenthal added. “The land usage efficiencies and low-profile design of Pyron's system will produce cost savings to help renewable energy become a cost-competitive and serious alternative to fossil fuels.”
