Effect of coloring covers on the electrical parameters of a photovoltaic module

Abstract

The efficiency of a photovoltaic module can be affected by different factors, including irradiance and temperature, so the environmental conditions to which it is subjected have a great impact on photovoltaic generation. The present work deals with the analysis of the electrical parameters of a photovoltaic module when it is exposed to the elements and the cells are covered with a layer of plastic material, in this case cellophane, characterized by being thin and having some transparency. The analysis was carried out with pink, red, orange, yellow, lemon green or light green, green, blue and purple cellophane. In addition, a nano-ceramic gray coating to polarize crystals was added to the tests. This with the purpose of observing if a coating is capable of filtering light for the convenience of the module's operation, improving its performance. The results obtained show that the pink coating is the one that has the least impact on the parameters, while the nanoceramic gray film has the greatest impact.
