RESEARCH STATUS AND PROSPECT OF PHOTOVOLTAIC-GREEN ROOF
The research status of photovoltaic-green roof was expounded from the following four aspects:1)Thermal and humid environment and vegetation state on the roof;2)Power generation efficiency of photovoltaic modules;3)Water balance of roof;4)Energy balance and thermal process model of roof.The results show that the interaction between PV modules and vegetation varies dynamically under different climate and spatial configuration conditions,which leads to uncertainties in the comprehensive performance of the roof.Finally,the engineering challenges faced in the application of photovoltaic-green roof and future research directions was analyzed and prospected.And it is pointed out that understanding and applying the interaction mechanism between photovoltaic modules and vegetation lays the foundation of accurate prediction and optimization of comprehensive performance of photovoltaic-green roof.
