Studio Rinnovabili is a partner of BP Solar for the design of PV plants in Italy. BP Solar is a principal world supplier of several photovoltaic technologies.

It is important to distinguish this technology from the solar thermal technology, which captures sun energy to heat water for thermal uses, or sometimes to generate electricity through a thermodynamic cycle. 

A PV solar plant transforms directly the sun energy in electricity. This a property of some materials like silicon to allow the conversion of electromagnetic energy of photon into electricity. PV plants can be classified in two categories:  

Stand-alone, which means that the system is connected to an isolated net, energy powers directly the users and charges a pack of electric batteries. During night the battery pack supplies energy.

Grid-connected, in which energy is delivered to the national net and accounted for. On a parallel connection energy flows from the national net to the users. The two systems are technically separed, and if there is a black out the system will not supply energy to the users. On the other side the electric company (Enel or whatever) will apply a net metering to its bill, discounting the production from the consumption.

In Italy actually a common grid connected PV plant can cost around  6.000 – 8.000 € (+VAT) per kW. It occupies a surface of 8 – 10 square meters, and it produces (if well installed) around 1.300 kWh / year hence allowing a domestic user a decrease in the bill of 150 - 200 € per year, apart from an eventual state subsidy (conto energia).
