Pannelli fotovoltaici illustrates that a photovoltaic system is an electrical system that uses solar energy to produce electricity by the photovoltaic effect. Photovoltaic systems are generally divided into two major groups: stand-alone and grid-connect systems. The power rating of a PV system is measured by the sum of the rated output of each photovoltaic module that makes up its field. The largest photovoltaic plant in operation in the world is Olmedilla de Alarcón PV Park in Spain...

Micro eolico illustrates wind turbines for domestic use. Such a turbine is primarily made up of a tower with a height of 10 to 30 feet, planted in the ground and fastened by several bolts. On top of the tower is installed a wind generator that consists of a series of blades (usually three) and an alternator. The higher the position of the turbine faster the wind, the greater the power generated...
