Thermal And Electrical Performance Investigation Of Solar Photovoltaic Module With And Without Cooling System

Abstract

Electricity Generated By Commercial Solar Photovoltaic Module Is Inversely Proportional To Module Surface Temperature And Directly Proportional To Solar Radiation Intensity. Manufacturer TestPhotovoltaic Module Power Output At Constant Temperature. Actually, As Surface Temperature, Increase The Power Output And Its Efficiency Decrease. This Is Due To A Rise In Intrinsic Carrier Concentrations At Higher Temperatures, Which Tend To Increase The Dark Saturation Current Of The P?�?N Junction, Causes The Open-Circuit Voltage To Decreases. To Decrease This Effect Cooling Pv Module Surface Is One Of The Solutions Of This Problem. The Main Aim Of This Study Is To Develop And Experimentally Test The Thermal And Electrical Characteristics Of Solar Photovoltaic Module With And Without Cooling System. The Study Set Up Consisted Of Two Polycrystalline Pv Modules Of Solar Area 0.945 M ?? 0.55 M With Power Output Of 60 W Integrated With Either Air Or Water-Cooling System. Theoretically, The Tilted Surface Solar Radiation And Solar Radiation Absorbed By Photovoltaic Module Were Estimated To Compute The Thermal And Electrical Efficiencies Of The Pv Modules. Experimental Test Was Done On Bar) And Cooled Photovoltaic Modules Exposed To Sun Towards East, West, And South Axes Of Earth For Four Cases Of Cooling Arrangement: Continuous Film Water Cooling Versus Bare Module; Continuous Air Cooling Versus Bare Module, Intermittent Water-Cooling Versus Bare Module, And Continuous Film Water-Cooling Versus Continuous Air Cooling. Typical Day Experimental Results Show That The Maximum Uncooled Average Surface Module Temperature Was 50.4, 58.64 And 55.4??? For South, West And East Facing Pv Modules,Respectively. The Result Illustrated That The Photovoltaic Module Film Water-Cooling, Intermittent Water And Air-Cooling Were Decrease In Temperature 20.45, 15.5, And 9.35???, Respectively. The Maximum Average Current And Voltage Output Of The Module For Film Water, Intermittent Water, And Air Cooling Cases Were 3.38, 3.26, And 3.4 A And 19.54, 19.53 And 19 V, Respectively. For South Facing Module, 23.15% Increases In Electric Power Output And Efficiency Was Observed For Continuous Film Water-Cooled Pv Module When Compared With
