Abstract:
The paper presents experimental measurement of the physical characteristics of a two-axis photovoltaic system with a 50W polycrystalline solar module (energy efficiency, power, UI characteristics, temperature) under current meteorological conditions (intensity of solar radiation, ambient temperature, wind speed). Measurement of the power of solar panels was made using PV-KLA (Germany) devices, and the ambient parameters were measured using the Davis Vantage Pro (USA) automatic weather station. The paper presents the results of measurements and a comparative overview of calculated power, energy, and efficiency values in relation to fixed panels.

Key words:
