Performance analysis of mono-crystalline and poly-crystalline silicon solar cells under different climatic conditions : a comparative study

Abstract

This study is based on dealing with two types of solar panels those are mono-crystalline and polycrystalline panels. We carried out the experiments to compare the efficiency and the cost for the two types of panels. In Bangladesh mostly polycrystalline panels are used to set up a solar energy system in a normal household where as our calculations suggested that mono-crystalline panel would be a better choice for installing in a home [9]. The main factors affecting the solar energy system that came in our concern was temperature and illumination. Depending on these two factors we saw how different cell parameters (series resistance, ideality factor, short circuit current, open circuit voltage, fill factor) varied. This in turn affects the cell performance and output. This work aims to study the effect on the behavior of both mono-crystalline and poly-crystalline silicon solar panel and develop a comprehensive model to calculate the cell output that takes into account the effect of different parameters under different environmental conditions. The model is used to calculate the cumulative cell output for over a year for the two types of solar panel.
