The paper describes performance of the grid-connected 1-kW PV system installed on a grammar school in Warsaw after two years of operation. The system consists of twenty Millennia MST-50 MV modules and inverter Sunny Boy GCI 1200. The performance of the system is continuously monitored according to guidelines in IEC 61724. Energy production in the first year was about 740 kWh and it was slightly higher than expected with respect to the simulation done before installation. In the second year, the energy production was about 680 kWh. The measured efficiency of the PV modules is about 5%, efficiency of the inverter is about 92% and efficiency of the entire PV system exceeds 4%. The performance ratio is in the range from 0.5 to 0.8.
