Abstract

This research was conducted to study the effects of module orientations and operating temperature on the performance of 3 identical photovoltaic modules. The objective of the research is to study and verify how the performance of the modules varied according to the parameter changes. Additionally, the daily distribution of solar irradiance is also looked into. The modules are mono crystaline silicon modules, each with 36 cells, each with a l00cm² surface area. They are each tilted at an angle of 5.98°, 15.98° and 25.98° and faced South. A wedge shaped wooden frame is used for each panel at each tilt angle. The results show that during the period when the experiment was conducted, the module tilted at 5.98° has a higher coefficiency at low irradiance while the coefficiency of the module tilted at 25.98° has the highest increase rate when irradiance increases. The effect of temperature is inconclusive because the result contradicts the fact that monocrystaline silicon solar cells have a negative temperature coefficient. The result shows that the modules have a slightly positive efficiency increase as temperature increase
