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.

Can a warehouse be converted into a rooftop solar site?

In Anhui, an old industrial warehouse has been converted into a 5 MW rooftop solar site. This site now powers cold storage units and feeds extra power back to the grid. China added 60 gigawatts (GW) of new solar power capacity in the first three months of 2025.

How does rooftop PV work in Guangzhou?

Residential areas contribute 50% of the total rooftop PV potential in Guangzhou, China. The rooftop PV potential in Guangzhou reaches 44.06–72.12 billion kWh per year. Rooftop PV reduces carbon emissions in the power sector in Guangzhou by 72.12–100%. Carbon price and subsidies have little impact on investment returns.

Why has rooftop PV soared in China?

Rooftop PV accounted for 60%, or 36 GW, of that total, marking the largest quarterly capacity addition for distributed PV in China’s history. The surge was largely driven by the urgency to meet policy deadlines set by the National Energy Administration’s (NEA) new guidelines, which were released in October last year and put into effect this May.
