Cogenra Solar has developed a new rooftop solar energy system that combines solar water heating and with solar PV panels, allowing it to convert a whopping 80 percent of captured solar energy into usable energy.
The solar cogeneration array includes silicon PV cells, concentrating mirrors that track the sun and a solar thermal transfer system that captures what would be waste heat from a PV array and turns it into hot water. The system also uses the thermal system to cool the PV components, allowing the cells to have a higher energy output.
The system can produce 50 kW of electricity and the equivalent of 222 kW of thermal energy.
The great thing is that this system utilizes already-existing technology but just combines them in a way that makes them even more effective and beneficial. If all rooftop arrays were made to viagra online pharmacy generic combine the www.hasselaar.nl two forces of solar PV and solar water heating, buildings could see a much greater energy payoff.
