China Solar Equipment Exports Fall 21% as Domestic Correction Drags on Overseas Volumes
A 21.4% year-on-year drop in Chinese solar equipment exports shows the domestic post-boom correction is now suppressing overseas shipments too.
Chinese customs data for July showed solar equipment exports down 21.4% from a year earlier, Reuters reported on Tuesday (2026-08-18), extending a contraction that began with a domestic installation collapse and has since pulled down China's overseas shipments.
China controls over 70% of global solar manufacturing across the supply chain, from polysilicon and cells through finished modules, according to The Economist. A sustained Chinese export contraction carries weight for any market built on cheap Chinese supply.1
The domestic origin of the slump is well-established. Chinese developers added only a fraction of the 45 GW of solar capacity installed in April 2025, when companies rushed to connect ahead of a repricing of solar power output, the Centre for Research on Energy and Clean Air reported. Across the first quarter of 2026, new Chinese solar additions totalled 41.4 GW, a 31% year-on-year fall, according to official data cited by OilPrice.com.2
Production tracked demand lower. Solar cell output in China fell 25.6% year-on-year in April 2026, CREA said, reflecting the collapse in domestic installations alongside a pullback in exports after a surge in March 2026.2
Beijing also removed export tax refunds on solar products from April 1 (2026-04-01), a step analysts had expected would push up panel prices and slow shipments materially. Yet July customs data show the export contraction continuing. The tax removal alone does not account for the magnitude of the decline.2
The Philippines has been absorbing a growing share of what China still ships. China exported more than 3,000 MW of solar panels to the Philippines in March and April 2026 alone, pushing the country past Pakistan to become China's second-largest solar export market, according to an Ember report cited by Asian Power.3
The pull is a widening cost gap. Meralco, the dominant Philippine utility, raised residential retail prices by 17%, commercial by 18%, and industrial by 14% over the past year, while solar installation costs fell about 10%, Ember data showed. But imports are flowing in faster than installation is absorbing them.3
The Philippines took in 5,068 MW of solar panel capacity during 2025, more than five times the 800 MW of grid-connected utility-scale solar installed that year, Ember reported. Rooftop capacity grew from 721 MW in early 2025 to about 1,300 MW in early 2026. The gap between imported panels and connected systems is large, even accounting for distributed projects outside the grid-connection figures.3
Ember estimated that rooftop solar paired with battery storage in the Philippines could reach 3,500 MW of capacity and 4,500 MWh of storage within 24 months, volume on the scale of the Meralco Terra Solar project. Whether deployment accelerates fast enough to consume the existing inventory is an open test for that forecast.3
Dan Wang, an analyst at Gavekal Dragonomics, has argued China's lead in solar technology is likely irreversible. For Chinese manufacturers, though, the near-term pressure is more basic: the domestic market absorbed a record 45 GW in a single month last year and is now digesting the policy aftermath, while Southeast Asian buyers are themselves sitting on imported panel volumes that outpace their connection rates.1
Globally, 511 GW of new solar capacity was added in 2025, much of it driven by falling panel costs, The Diplomat reported.4 Still, the July export figures suggest Chinese shipments are slowing even as regional demand builds, and the 5,068 MW of panels in the Philippine supply chain above what has been connected to the grid shows how quickly import appetite stalls when deployment bottlenecks bite.3
