Quanto costano i pannelli fotovoltaici?

Quanto costano i pannelli fotovoltaici? I dati raccolti da Enea indicano che il costo medio di 1 kW è pari a circa 3.500 - 4.000 euro. I moduli fotovoltaici alla base di questo preventivo sono moduli ordinari in silicio policristallino . E' chiaro dunque che queste cifre possono variare, in positivo e in negativo, anche del 30%, in funzione della qualità and type of modules installed. Depending on the type of the selected panels, also changes the size. Monocrystalline panels, set in approximately 8 square meters of roof per kW, while those of amorphous silicon will take up a lot more about 20 square meters per kW. Whereas for an installation for an average family of 4 includes the installation of a 3 kW, the account is easily done: it takes about 10,500 to 12,000 euro, all inclusive, turnkey. Of course this is just an example, because the size of the plant depends not so much the number of people who live in that house, or from the surface of the property, but from what the family is energy-consuming. If you're wondering if there are other costs to consider, know that maintenance is virtually non-existent, because there will only be paid the costs of cleaning the panels.
