rooftop solar storage cost vs benefit calculation in China

How to evaluate the profitability of rooftop PV systems in China?

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).

Are solar energy resources a risk factor for rooftop PV system construction?

The study revealed that areas with abundant solar energy resources and higher electricity prices have a lower economic risk for rooftop PV system construction under the current subsidy price and cost. This finding provides valuable insights and serves as a reference for constructing rooftop PV systems in different regions of China.

Can rooftop solar be deployed in China?

This study moves beyond technical estimates to assess the deployable rooftop solar potential across 367 Chinese cities, factoring in real-world constraints. The findings offer actionable insights to guide strategic deployment and support China’s ambitious solar energy goals.

Is small rooftop photovoltaic a good investment in China?

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.–0.5573CNY/kWh, so the economic performance is good.

Is rooftop PV self-consumption possible in China?

Therefore, this paper makes a comparative study on the rooftop PV self-consumption potential of industrial and commercial users in 20 regions of China, analyzed the impacts of different electric prices and shading conditions on the system's feasibility, provides advice for companies and policymakers to develop rooftop PV deployment.

Are rooftop PV systems a good investment?

For cities with rich solar energy resources (such as Mohe), rooftop PV systems can yield substantial benefits, even under high shading. However, in cities like Urumqi, despite having ample solar energy resources, the on-grid electricity prices are relatively low, leading to much lower investment returns and longer investment payback periods.
