The object of the project is the purchase and installation of 41 photovoltaic installations, 9 photovoltaic installations with air-conditioning heat pumps, 4 photovoltaic installations with air-containing heat pumps, 8 airborne heat pumps and 5 airborne hot water heat pumps. Photovoltaic installations will be designed for the production of electricity (generation systems with a power from 1, 8 kWp up to 4.8 kWp, consisting of 300 Wp monocrystalline modules, each to be installed directly on residential or auxiliary buildings and the electricity produced by the PV power plant will be used to cover the energy needs of buildings) and the air heat pumps will collect heat from the surrounding area and deliver it to central heating and hot water installations, either by heating water or for a ventilation system, by heating the air supplied to the household premises.
