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. C raise in module temperature.

Photovoltaic system performance is a function of the climatic conditions, the equipment used and the system configuration. PV performance can be measured as the ratio of actual solar PV system output vs expected values, the measurement being essential for proper solar PV facility''s operation and maintenance. The primary energy input is the global light irradiance in the plane of the solar arrays, and this in turn is a combination of the direct and the diffuse radiation.
