不同倾角对PV-PCM系统冷却性能的影响OA

Photovoltaic power generation technology has widespread applications,with factors affecting its efficiency including solar ir-radiance intensity,photovoltaic cell materials,and temperature.Since irradiance intensity is highly influenced by environmental con-ditions,and cell materials face challenges such as cost,stability,and technological maturity,controlling cell temperature emerges as a practical method to enhance efficiency.Using phase change materials(PCM)for cooling represents the most promising temperature control strategy.According to the influence of the inclination angle of the photovoltaic(PV)-PCM coupling system on the melting process characteristics of phase change materials in the rectangular container at the back of the battery and the thermal management issues,it studies the influence of the inclination angle of the PV-PCM system on the temperature of the solar panel and the photovoltaic electrical performance.Under simulated conditions of 600 W/m2 solar irradiance,180 minute irradiation duration,30 mm phase change material thickness,and vertical panel orientation,experiments compare temperatures of PV-PCM systems at 15°,30°,45° and 60° inclination angles against standalone PV panels.Results confirm the cooling effect of phase change materials,with panel operating temperatures decreasing as inclination angle increases.Furthermore,as the inclination angle of the PV-PCM system increased From 15°to 60°,the maximum power output,open-circuit voltage,fill factor,and maximum conversion efficiency of the panels all improve with increasing inclination angle,while the short-circuit current decrease.
