China’s Solar Installations Decline In Q1 2026 After Record-Breaking Growth Year

China’s solar energy sector has entered a phase of adjustment in the first quarter of 2026, recording its first quarterly decline in installations in five years. According to the National Energy Administration (NEA), the country added 41.39 GW of new solar photovoltaic (PV) capacity between January and March. This marks a sharp decrease compared to the 59.71 GW installed during the same period in 2025, signaling a slowdown after a period of rapid expansion.

The dip comes on the heels of a record-breaking year in 2025, when China installed more than 315 GW of solar capacity. Much of that growth was driven by developers rushing to complete projects ahead of a June 1, 2025, deadline, which marked the shift from fixed pricing mechanisms to a more market-driven system. This transition has now led to a cooling-off period as the industry adapts to new pricing structures and competitive bidding processes.

A closer look at the monthly data highlights this shift. In the first two months of 2026, China installed a combined 32.48 GW of solar capacity. However, March saw a noticeable drop, with only 8.91 GW added. This trend suggests that demand is stabilizing as stakeholders adjust to the evolving market environment.

Industry forecasts had already anticipated such a slowdown. The China Photovoltaic Industry Association (CPIA) had projected that solar demand in 2026 could fall by 24% to 43% compared to the previous year. Current estimates indicate that total installations for the year may range between 180 GW and 240 GW, reflecting a more measured pace of growth compared to 2025’s surge.

Despite the decline in quarterly installations, China’s broader renewable energy ambitions remain firmly on track. By the end of March 2026, the country’s total power generation capacity reached 3.96 terawatts (TW), representing a year-on-year increase of 15.5%. Solar energy accounts for 1.24 TW of this total, while wind power contributes 660 GW. Together, these two sources make up a significant portion of China’s growing clean energy portfolio.

Looking ahead, China continues to pursue long-term expansion through its 15th Five-Year Plan. The strategy includes the development of ten large-scale clean energy bases aimed at strengthening renewable capacity. To achieve its 2035 target of 3.6 TW of combined solar and wind capacity, the country still needs to add around 1.7 TW over the next decade.

While 2026 may reflect a period of slower growth, the overall outlook for China’s solar sector remains strong, supported by policy direction and sustained investment in renewable infrastructure.
