The main objective of the task is the production of electricity from renewable sources. Thanks to the investment consisting of the construction of 11 photovoltaic micro-installations on the roofs of 7 residential buildings, at least 39.75 MWh of electricity will be produced per year, of which 7.95 MWh will be used directly, while 31.8 MWh will be introduced into the network and then (in accordance with the applicable prosumer regulations) used for the Investor in the amount of 25.44 MWh. In addition, the aim of the project is to rationalise the costs of the Investor by replacing part of the energy purchased from the network by own production, reducing the consumption of fossil fuels and reducing emissions of pollutants into the atmosphere resulting from the production of electricity through the use of renewable energy sources (photovoltaic installations). The result of the task will be 11 photovoltaic installations with a total power of 39.75 kW (1x7.5kW, 2x6kW, 1x4.5kW, 1x3.75 kW, 2x3kW and 4x1.5kW).
