Photovoltaic power generation is the main alternative to coal power generation, in order to reflect the environmental benefits of photovoltaic power generation, this paper integrates the net carbon transaction cost and environmental protection tax in the life cycle of photovoltaic power generation into the calculation of indicators of LCOE and IRR, selects eight representative regions of China’s roof photovoltaic for economic benefit evaluation, and selects four indicators for sensitivity analysis of LCOE and IRR. The results show that the cost reduction range is 0.0083-0.0593 Yuan / kWh under the condition of measuring the net carbon dioxide, sulfur dioxide and nitrogen oxides emissions, the establishment and improvement of carbon trading market and environmental protection tax will help to improve the economic benefits of users; other regions can achieve user side parity without considering the financing cost except Chongqing; reducing the cost of photovoltaic power generation and improving the unit power generation are the main factors to improve the economic benefits.
