A photovoltaic system is able to capture and transform solar energy into electricity.
It consists in a series of electronic, electric and mechanical components that transform solar energy into electricity and supply this to consumers. It is called “grid connected” because it is linked to a distribution grid. This means that besides supplying the user, it also exchanges power with the grid.
The environmental benefits obtainable by adopting photovoltaic systems are proportionate to the quantity of power produced, supposing this replaces the energy otherwise supplied from conventional sources.
To produce 1 kWh of electricity the equivalent of 2.56 kWh is burned in the form of fossil fuels (natural gas) and consequently about 0,531 kg of CO2 enters the atmosphere.
It can therefore be said that for 1 kWh produced by the system, the emission is avoided of 0.531 kg of carbon dioxide into the atmosphere.
