The results show that: For small rooftop photovoltaic in China, first of all, under the existing subsidy price and cost, its investment payback period is short and the risk is low. Secondly, the average internal rate of return is more than 10%, and the levelized cost of electricity is 0.2727–0.5573CNY/kWh, so the economic performance is good.
Furthermore, a system efficiency of 0.9 was considered satisfactory. This systematic technique guarantees a thorough examination of the capacity for generating solar energy from rooftop installations, enabling well-informed decision-making about efforts for energy sustainability.
By implementing rooftop solar PV systems, schools can significantly reduce their reliance on conventional energy sources, which are typically associated with higher costs and environmental degradation. This transition aligns with China's national renewable energy goals and carbon reduction targets, as outlined by the NDRC (2022).
