The Effect of Environment on Photovoltaic Module Efficiency

As a great potential renewable energy source, solar energy is going to become one of the most important energies in the world. Recently, there has been an enormous increase in the understanding of the operational principle of PV tools, which led to a sudden increase in the power conversion efficiencies of such tools. Solar modules vary under temperature changes and the change in temperature will affect the output power modules. In this paper a relation between efficiency, sun radiation and temperature is used and under cloudy climate is simulated so we can obtain desired efficiency by adjusting temperature around PV module.
