COMPARISON OF MEASURED AND CALCULATED ELECTRICAL ENERGY CAPTURED BY PHOTOVOLTAIC PANELS

Abstract

The main goal of the work was the measurement of photovoltaic panels on a family house in the village of Lucka in eastern Slovakia during 4 months. The panels were mounted on the south side of the building at a slope of 26 degrees. The measurement took place every day only during sunshine. Subsequently, the comparison of these actually measured values with the calculated values from the PVGIS software, which also serves to calculate photovoltaic panels. Photovoltaic panels were measured in the months of April, May, June, July in 2021. As was mentioned, the measurement took place only during sunshine, i.e. when the sun's rays hit the photovoltaic panels. From these measurement results, we will find out how much electricity we will actually produce in these months and how much the software will "produce" if we enter the same parameters for the location and type of photovoltaic panels as for a family house.
