Photovoltaics panels – Economic return based on the real effectiveness

Abstract

This article examines the efficiency of photovoltaic panels in a real environment and their economic returns over their lifetime.Introductory section describes the general principle of converting sunlight into electricity and judged the system on which measurements were taken. The next part deals with the determination of the efficiency of photovoltaic panels and this issue of conversion of the direction of the solar radiation flow on a horizontal surface of a solarimeter towards the direction normal to the plane surface of the photovoltaic panels is described. On the basis of this transfer can be determined by the total global radiation falling on the surface of the PV panels and determine their true effectiveness. It is described effects of air pollution on the efficiency of PV panels. The last section deals with the economic return assessed system.
