Research of material and power of photovoltaic panels of various types of degradation in operating conditions

Abstract

Abstract. The paper deals with the results of research on the influence of material and operating parameters on the performance characteristics and efficiency of photovoltaic panels. The disadvantage of PV panels is that their performance depends on a number of factors such as the intensity of the sun's radiation, the outside air temperature, the surface temperature of the photovoltaic panel, its pollution, shielding, etc. In the paper is analyzed the model photovoltaic power plant, from which data were obtained during the monitored period and subsequently the progress of individually measured parameters was evaluated.

“…Concerns about the environment, especially about continuous using of fossil fuels and their stocks, increased interest in low-emission transportation, such as electric vehicles, but also about harnessing wind/solar energy (1,2). It does not matter whether a battery operates in a hybrid electric vehicle (HEV) or as a backup systems.…”
