From December 2021 to July 2022,359 offline users were surveyed in person and 410 online users were surveyed online,and SPSS software was used to test the survey data.The survey results show that the respondents have stronger willingness to install PV because they know more detailed PV information.Most of them can accept the initial investment of PV less than 50000 RMB.Photovoltaic income and service life are their primary concerns,and it is believed that the biggest factor affecting photovoltaic investment when the initial investment is too high.Based on the research results,the photovoltaic system with an initial investment of 50000 RMB is designed.Considering the investment mode,subsidies,loans and other factors,the annual yield of photovoltaic under different investment modes is 9.73%～13.43%,and the return period of investment is 5.38-7.76 years.Combined with the policy-the proportion of photovoltaic power generation that can be installed on the roof of rural residents is not less than"20%",the average annual carbon reduction is16500～86800 tons.Meanwhile,this paper puts forward feasible suggestions for the future development of rural roof photovoltaic according to the research results.
