To further optimize the resource structure, reduce the energy gap and alleviate environmental pollution in China, a scientific evaluation and decision-making mechanism of photovoltaic (PV) power generation projects is in urgent need of establishment, and the comprehensive performance evaluation system of PV power stations should to be improved to promote the sustainable development of the whole social energy system. Focused on the comprehensive evaluation technology for PV power generation units. Based on the basic principle of “multi-criteria, multi-level and multi-factor” decision-making, a comprehensive evaluation system and an evaluation method suitable for PV power generation units are proposed, which comprehensively consider the advantages and disadvantages of objective and subjective weight methods. The principle of minimum discriminant information is used to calculate the combined weight, and a comprehensive evaluation model for PV power generation units is established to compare and analyze the comprehensive evaluation results of a novel PV medium-voltage power generation unit and a conventional PV power generation unit, thus proving the superiority of the design indexes for the novel unit.
