SPIC Passes 100 GW of Installed Solar, 200 GW of Clean Capacity

State Power Investment Corporation's installed photovoltaic capacity passed 100 million kilowatts at the end of July 2026, a more than 14-fold increase. Clean energy capacity crossed the 200 million kilowatt mark, roughly 75% of the group's fleet, generating 420 billion kilowatt-hours a year.

That annual output figure is the number that sets the scale. At 420 TWh, the group's clean fleet produces more electricity in a year than most national power systems consume, and it does so from a portfolio in which three quarters of nameplate capacity is non-fossil.

The solar buildout sits on manufacturing and research assets held inside the group. An engineer on the XBC cell pilot line, Wei Rong, said polysilicon cell conversion efficiency stood at 18.3% a decade ago, against 26.81% today for the high-efficiency N-type TBC cells the company developed, with module products sold into the European market.

On tandem architectures, the company reports 27.15% efficiency for large-area four-terminal tandem modules and 33.18% for small-area perovskite/silicon tandem cells. Those are laboratory and pilot-scale figures, not fleet averages, and they mark where the internal technology roadmap currently sits rather than what is being installed.

The XBC pilot line at Huanghe Company entered service in 2019 with an annual capacity of 200 MW, filling what the group describes as a gap in domestic mass production of IBC technology in China.

End-of-life handling has its own asset. The first domestic pilot line for module recycling built by the company reports an overall recovery rate above 95%. Recovery rates at that level matter for a fleet of this size, where the volume of panels reaching retirement is a function of installed base rather than of policy timing.

Operations are organised around what the group calls a two-hour working circle, supported by 129 regional maintenance and inspection centres and 681 intelligent new-energy stations. That density of service infrastructure is the operational counterpart to a 100 GW solar fleet spread across sites that are frequently remote.

Site-level performance data comes from the 700,000 kilowatt Fushan photovoltaic project in Qinghai, where a 100,000 kilowatt demonstration block reaches an overall system generation efficiency of 86.5%, applying new high-efficiency cell and module technology and new tracking systems.

At Talatan, in the Hainan Tibetan Autonomous Prefecture of Qinghai, more than 7 million solar panels form what the group states is the world's largest photovoltaic park by installed capacity. The desertification rate at Talatan previously reached 98.5%; vegetation coverage inside the park has since risen to 80%.

The portfolio is not solar-only. The third-generation nuclear programme Guohe No 1 has mastered more than 300 key core technologies and secured more than 14,000 intellectual property titles. In hydrogen derivatives, the Da'an green ammonia demonstration project entered trial production in 2025 and exported 3,750 tonnes of green ammonia to South Korea.

Grid-side integration shows up in the Huolinhe local network, where green power accounts for 48.57% of installed capacity, and in hydrogen fuel-cell vehicles from Guoqing Technology that have passed 130 million cumulative kilometres.

For investors benchmarking utility-scale renewables, the relevant comparison is not project size but vertical span: one operator holding a 100 GW solar fleet, a 200 MW cell pilot line, a module recycling line above 95% recovery, a third-generation reactor design, and a green ammonia export cargo. Western majors have shed or spun out most of the manufacturing and nuclear engineering layers that sit inside this single balance sheet.

The efficiency spread reported across the group's own technology stack, from 18.3% polysilicon a decade ago to 33.18% in small-area tandem cells, is the internal metric to track. Whether tandem figures migrate from small-area cells to large-area modules at scale determines how much of the next capacity increment comes from higher yield per hectare rather than from more land.
