Ltd.10.26689/pbes.v7i6.9117ArticleAnalysis of Investment Efficiency in New Energy Projects by Traditional Energy Enterprises: A Case Study of Rooftop Photovoltaic Power Projects in the Chongqing Regional Markethttps://artdesignp.com/journal/PBES/7/6/10.26689/pbes.v7i6.9117ZengRunqi,WenXiangyu,GouXiaochong,WangNa,ZhouZiqi,PengLin2024762024-12-23Under the “dual carbon” goals, transitioning effectively in the traditional energy industry requires investment in photovoltaic (PV) power projects as a major development direction. Accurately assessing the investment efficiency of PV projects is a crucial reference for project decision-making. This study analyzed PV power generation evaluation methods and project efficiency models, integrating national and industry reports to select an appropriate model for calculating PV project efficiency. Using facilities suitable for rooftop PV projects in certain traditional energy enterprises in Chongqing as examples, the study calculated that the internal rates of return (IRR) for all test sites exceeded the enterprises’ capital costs, confirming their investment value. Recommendations include: (1) Prioritizing projects with higher efficiency; (2) Simultaneous implementation of projects with similar efficiency in the same administrative area; (3) Maximizing surplus electricity revenue in cases of excess generation. This research aims to support traditional energy enterprises in transitioning to new energy projects and offers a reference for calculating investment efficiency in various PV power projects, including ground-mounted and wall-mounted PV systems.
