Outline
According to the different conditions of photovoltaic resources, ongrid price, initial total investment and light abandonment rate in various regions of China, a photovoltaic economic evaluation model is constructed to analyze the ongrid situation of photovoltaic power generation parity in various regions and calculate the minimum ongrid price and the maximum initial total investment that meet the benchmark yield in each region. The results show that there are obvious regional differences in China's photovoltaic economy. Considering the abandonment of light, a total of 15 regions in the country cannot achieve grid parity access, but most of them are close to parity access. Some regions with high photovoltaic economy can achieve parity with a price of 0.05 CNY/(kW·h) below the benchmark price. The research results of this paper are helpful to the investment decisionmaking of photovoltaic projects and the formulation of relevant policies.
