The previously separated photovoltaic and solar thermal collector systems are successfully combined to provide the advantage of two systems in one. If the surface temperature reaches 176° F, the combi-module can be quickly cooled to below 68° F using 54° F cold water. This results in an efficiency increase of up to 30 percent.
With an average ambient temperature of 84° F, the panels produce 15 percent more electricity per year.
