ABSTRACT
Research into photovoltaic modules in the highlands, based on the example of the Żywiec Beskids, was conducted in 2009 in the town of Stryszawa on the border between the regions of Lesser Poland and Silesia. It involved measurements of the quantity of the produced electric power in three different systems of diverse power (570 Wp, 360 Wp oraz 200 Wp) and different technical solutions (rotary modules tracing the Sun rotation and stationary modules). Efficiency of the photovoltaic modules was compared to the intensity of the solar radiation in the city of Żywiec. This way the efficiency of the solar energy processing was determined. The conducted research indicates that with the intensity of the solar radiation amounting to 890 kWh/ m2·year it is possible to produce electric power in the quantity of over 150 kWh/m2·year (rotary modules) or about 110 kWh/ m2·year (stationary modules). The highest efficiency of the solar energy processing into the electric energy has been observed in the winter season (ca. 26%).
