Evaluation of Thin Film Amorphous Silicon Solar Energy System

Abstract

This paper focus on the evaluation of  thin film amorphous silicon solar panel and one model which is based on mathematical equations of generating photovoltaic current and efficiency of solar energy system . This model have been developed with the help of LabVIEW software. The developed model allows the prediction of generating photovoltaic current under different solar radiation, Efficiency of solar panel, efficiency of solar water pump & the efficiency of total energy system.  In order to validate the developed model, an experimental test setup was built and the results are found to be in close agreement with the observed reading of current shown by solar power conditioning unit. The analysis of graph shows that the difference between predicated current and actual current error does not exceed 5%.

Keywords: Amorphous silicon solar panel, LabVIEW, photovoltaic current, solar radiation.
