Rooftop container solar energy

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.

Are rooftop solar photovoltaics sustainable?

Provided by the Springer Nature SharedIt content-sharing initiative Rooftop solar photovoltaics (RPV) are vital for sustainably powering cities. However, most existing studies focus on RPV’s technical or economic potential often overlook real-world electricity consumption and regulatory constraints that shape actual deployment.

How much RPV can a rooftop area generate?

Combining the suitable rooftop area with hourly PV capacity factor analysis (Methods), we estimate 2,785 GW (95% confidence interval: 2,760 GW and 2,809 GW) of technical RPV potential capacity and 4,631 TWh (95% confidence interval: 4,589 TWh and 4,671 TWh) of technical RPV annual generation across mainland China.

What role will solar photovoltaics play in China's future power portfolio?

Solar photovoltaics (PV) will play a significant role in future power portfolios in China, accounting for as much as 40% of the total installed capacities 3 and national electricity demand in carbon-neutral systems in 2060 (ref. 4).
