Distributed PV Momentum Lifts China’s Rooftop Solar Market Toward $19.6 Billion by 2035

China rooftop solar panel market is estimated at $9.5 billion in 2025 and is expected to expand to $19.6 billion by 2035, registering a CAGR of 7.5% over the 2026–2035 forecast period. China’s rooftop solar segment is gaining traction as a key contributor to the nation’s ambitious clean energy transition. Distributed photovoltaic (PV) systems, including rooftop installations on residential, commercial, and industrial buildings, are reshaping how solar capacity is integrated into urban and rural energy systems. These installations help reduce grid strain, lower energy costs for end users, and support China’s broader goals of boosting renewable energy self?consumption while advancing rural revitalization and clean power equity. Government support for solar deployment and clear targets for distributed PV expansion are encouraging local authorities, corporations, and households to adopt rooftop solar at scale, reinforcing investor confidence and domestic industry growth.

According to the International Energy Agency’s Photovoltaic Power Systems Programme, China added a record 277.57 GW of new solar capacity in 2024, taking cumulative installed PV capacity to 886 GWAC. Distributed solar accounted for 43 % of new additions, equivalent to about 118.18 GWAC, reflecting strong momentum in rooftop and other decentralized installations. Growth was led by commercial and industrial systems, while residential installations moderated compared with earlier years. Data from the Institute for Essential Services Reform shows that by the end of 2024, cumulative distributed PV capacity reached 370 GW, representing 42% of total solar PV installations in China. Together, these trends highlight the expanding role of rooftop and distributed solar in shaping China’s solar deployment strategy.
