The subject of the project is the purchase and installation of solar heating systems of central water. Solar installations will be installed on private facilities. The total number of installations will be 6. Moreover, the task includes, inter alia, the purchase and assembly of complete photovoltaic installations (including components, i.e.: photovoltaic cell panels – PV panels, inverters, electrical switchboard, security, electrical and communication connections). Photovoltaic installations will use solar energy to support the production of electricity, thereby enabling the expected environmental impact. The total number of prosumer micro-installations will be 24, i.e. 24 individual objects
