The solar constant is the radiant power of the sun before it enters into the atmosphere: average measurement of 137G W/mq. In Italy, the average value of insulation is between 1200 and 1750 KWh/mq per year, Solar panel technology has the advantage of directly transforming sunlight into electric energy, through a passive process |without the absorbing or consuming energy). In fact, it uses the sun which is en unlimited fuel and does not release noxious emissions into the atmosphere saving lulograma of carbon di-oxide (C02). The use of integrated solar pane! systems architecturally can open up new frontiers in the formation of new building designs, where the constructive element becomes an active component which increases the amount of money saved on energy.
