Photovoltaic systems can also pay off in countries with a lower number of sunshine hours per day
Thanks to innovative technologies, solar energy can be highly profitable even in countries less blessed with sunshine. A solar system performs best on sunny days. But even when the sky is cloudy, it still yields significant energy recovery, because solar cells can also efficiently transform diffuse light. In addition, the efficiency of modern solar systems – i.e. their electric output yield as related to the solar irradiation received – is constantly on the increase. Thus, at present the efficiency of modern Panasonic HIT Modules is more than 18%.
