The problem is that not all roofs are created equal. Scientists from the University of Gothenburg have launched a tool that uses the actual conditions to

Solar Energy (both photovoltaic and solar hot water, aka solar thermal) are great resources to have at your disposal. In the case of photovoltaic, you can substitute the power from your utility grid by harnessing the sun’s power and converting the sun’s rays into electricity. With rising electricity prices, photovoltaics (aka solar electric) is a great hedge against ever expanding utility bills. The photovoltaic industry is growing by leaps and bounds. You may want to get into the action.
Israeli solar energy companies such as Solel Solar, Aora, Ormat technologies, and a host of others are now world leaders in the development of sun power to produce electricity. But Israel, a small country of 7 million, with more than half its land area being desert, has been a solar energy pioneer virtually since its beginning in 1948.
What is now fondly known to many Israelis as a “dude shemesh” or sun boiler, was invented by a guy named Levi Yissar back in the early 1950’s, when electricity was very expensive due to a severe energy shortage.
