Research Progress in Cooling Technology for Solar Photovoltaic Panels
The research progress in photovoltaic panel cooling technology at home and abroad in recent years is reviewed,and the advantages and disadvanta-ges of various cooling technologies are analyzed.For the air cooling method,under the same operating condi-tions,the cooling effect of forced convection circulation cooling is better than that of natural convection circula-tion cooling.The cooling effect of the water cooling method is better than that of the air cooling method.Surface water cooling has a significant cooling effect,and the water film can reduce the loss of solar radiation reflection on the surface of the photovoltaic panel and remove dust covered on the surface of the photovoltaic panel.The cooling effect of phase change materials is better,but their thermal conductivity is lower,and the heat transfer rate is slower.Heat pipe cooling,jet in-jection cooling and micro-channel cooling have out-standing effects,but the cost is high,and the mainte-nance is difficult.
