Popis: This paper presents the results of a one-year study investigating the efficiency of a photovoltaic system installed on a flat roof of a residential building in north-eastern Poland. The analyzed system, with a peak power rating of 4.77 kWp, comprised 18 polycrystalline photovoltaic modules and an inverter. This on-grid PV system was connected to the electrical grid in the building. In the analyzed period, the PV system generated 3966.54 kWh of energy, and the average monthly power output was 330.55 kWh. The total power output of the analyzed solar system could cover the annual electricity demand of a residential building in 94.4%. The monthly electricity gains from the analyzed PV installation would be sufficient to cover the energy needs of the building in 100% only from the beginning of April to the end of August. The electrical energy gains from the analyzed PV system were compared with those from similar PV installations in Germany, located at similar latitudes.
