Longi Green Energy Technology Co. Ltd. Longi Green Energy Technology Co. Ltd. (601012.SH) is China''s largest solar wafer producer. It reported a net loss of 5.2 billion yuan ($733 million) for the first half of 2024, a reversal from a 9.2 billion-yuan net profit a year earlier.
Finally, the study presented one economic analysis model to evaluate the profitability by combining the market cost of rooftop PV systems and electricity prices in China. The economic model included four indicators: payback period (static and dynamic), net present value (NPV), and internal rate of return (IRR).
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.
The growth of Residential rooftop solar (RRS) in some western countries has predominantly been driven by individual or market behaviour and has been extensively studied. However, the development landscape of RRS in China differs, and its driving mechanisms remain unclear.
According to the data in the table, it can be found that under the existing national subsidy policies, rooftop PV in these five regions has a very good economic performance. Considering the influence of other unstable factors in a year, the radiation amount range of China's five solar resource regions is 928-2333 kWh/m 2 [ 1 ].
1. Introduction Residential rooftop solar (RRS) for electricity generation is essential in the new power system and vital during the low-carbon green energy transformation, which is being adopted globally (Moore and Bullard, 2021). In recent years, China's RRS has been expanding rapidly, with the annual growth rate ranking first in the world.
For example, Ref.6 studied the impact of solar radiation amount of rooftop PV on economic benefits, and concluded that self-use PV system with the optimal inclination and more than 1000 kWh annual radiation amount is feasible globally.
