The U.S. government is working on photovoltaic systems active for 40 years

Photovoltaic systems able to operate for 40 years, compared to 20-25 as they do today, thanks to replaceable cells and construction of a multi-piece allowed the American company REhnu, dislodged by the University of Arizona, to be awarded grants for a million dollars from the Department of Energy of the U.S. government. The sum - awarded with the prize SunShot - is expected to bring new photovoltaic systems on the market, to make them accessible to all.
"Pretty good", according to the CEO of the company, Justin Elliott, the result was achieved thanks to the talent of Professor Roger Angel, who led to the start up of REhnu. He was able to see the possibility of achieving greater efficiency in the production of energy through the building alone photovoltaic systems breakdowns. The same Angel exepects his intuition to allow to produce the double or even more (2.5 times) of solar energy than what is obtained with existing photovoltaic and therefore the option to make solar more affordable in terms cost of the system and even more competitive compared to energy supply through traditional fossil fuels. The assignment of one of the 10 SunShot and sums certifies that the Obama administration shares this bet and tip on it to alleviate energy costs, increase supplies and continue on the path of sustainable development for the environment. The goal, stated by the same company, is time to get to an even more effective photovoltaic system - REhnu plans to put it on sale for 2015 - making full use of the possibility of an easier connection of the system to the electricity network and to accelerate the supplying of energy from the sun to the grid.
