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 pfizer viagra discount have a higher energy output.
The system can produce 50 kW of electricity and the http://www.aldentheatre.org/where-to-get-levitra 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 combine the two forces of solar PV and solar water heating, buildings could see a much greater energy payoff.
