Power Loss Analysis and Suggestions for Efficiency Improvement of Roof Distributed Photovoltaic System

With the gradual depletion of traditional fossil energy and the increasingly prominent environmental problems caused by it, China has proposed carbon peaking and carbon neutrality goals to promote the transformation of the energy structure. Solar energy is one of the important renewable energy sources, and roof-distributed photovoltaic power generation technology has a broad market prospect. Given the efficiency analysis of the roof-distributed photovoltaic power generation system, this paper first establishes an analysis model of the roof-distributed photovoltaic power generation system, analyzes the factors affecting the power loss of each link in detail, and further clarifies the distribution characteristics of the power loss of the system through simulation. Finally, some suggestions are put forward for the efficiency promotion of the roof-distributed photovoltaic power generation system.
