1. Introduction. Module temperature is an important factor that influences the power produced by a photovoltaic system (Ye et al., 2013, Lobera and Valkealahti, 2013).Typically, a crystalline silicon module loses about 4% of its power output for every 10 °C raise in module temperature.Since module temperatures above 45–50 °C are usual …
