A low cost solar array simulator using halogen tungsten bulb with temperature control capability

This paper proposes a configuration of a low cost solar module simulator (SAS), suitable for basic studies on PV systems. The utilizes the halogen tungsten bulbs as the light source. Furthermore, water tank is placed in between the bulbs and the PV module to control the rise in temperature. The halogen tungsten bulb is powered by DC voltage rectified from a three phase supply. Its light intensity is control by IGBT using high frequency switching. The SAS is capable of generating 1000W/m <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> of irradiation. During the experiment the PV modules temperature dropped about half to 53°C after using water filters in 15 minutes exposure to the 1000W/m <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> irradiation. To test the capability of the SAS, a case study involving PV system under partial shading is carried out.
