Abstract:
This study summarizes the results of large-scale photovoltaic power plants on the yield,quality,growth,and physiological metabolism of under-panel crops. Furthermore,three integrated developing models are put forward according to the photovoltaic industrial elements,the agricultural multifunctionality theory,and recent high-tech agricultural technologies. In addition,three profit models of agrivoltaic,coupling with the upper,middle and lower reaches of agricultural industry based on the smile curve theory,are also proposed. Finally,a case study of Qizhuoqizhou in Hubei province is carried out,and results show that it could achieve an increase in the internal rate of return of the project’s own funds by 1.36% to 1.70% under complementary development of combining solar energy with farming,as well as middle reaches profit model. These results will give useful information to push Chinese agrivoltaic development,and also to optimize profit model design for agrivoltaic systems that maintain crop production,produce renewable energy and increase farm profitability.
