THE EFFECT OF SOLAR IRRADIATION ON SOLAR CELLS

Abstract

Photovoltaic systems have been increasingly used in the generation of electrical energy, either as a means of providing electricity in areas where there is no grid connection (stand-alone systems), or by providing electricity to the grid (grid connected systems). In a deregulated energy market, the cost of energy produced from fossil fuels is rising and the photovoltaic energy becomes a promising alternative source. Yet it still suffers from problems that need to be resolved in order to be widely accepted as an equivalent alternative to fossil fuels. Firstly the more direct problem of efficiency and cost needs to be overcome and secondly the indirect problem of the quality of power provided by photovoltaic technology has to be addressed. In this work, the effect of irradiation of solar cell is studied, data were collected experimentally, a total of 28 data were collected in 14 days, and Microsoft Excel software was used to analyse the data. The effect of solar irradiation on solar cells was studied, and the irradiance pattern through the specific color spectrum was determined.
