PowerChina Launches Massive 31 GW Solar Module Tender for 2026 Projects
China Power Construction Corporation’s PowerChina solar tender
China Power Construction Corporation (PowerChina), a key player in the global energy sector, has announced a colossal tender for 31 GW of solar modules. This procurement is a central component of a wider 97 GW renewable energy equipment program designed to supply its projects scheduled for 2026. This strategic move aims to secure the company’s supply chain and signals a continued, aggressive push in renewable energy development, even as some analysts watch for a potential China solar slowdown in the broader market.
The tender specifies a clear preference for modern, high-efficiency solar technologies. The 31 GW total is divided into three distinct categories:
* 24 GW of n-type TOPCon (Tunnel Oxide Passivated Contact) modules, which have become a mainstream choice for utility-scale projects due to their high performance and efficiency.
* 4 GW of back-contact (BC) modules, a premium technology known for its superior aesthetics and power output.
* 3 GW of heterojunction (HJT) modules, another advanced technology offering excellent performance, particularly in high-temperature environments.
All prospective suppliers must provide modules that are bifacial and utilize cell sizes of 182 mm or larger. This focus on cutting-edge technology underscores the industry’s rapid evolution, which is driven by an increasingly sophisticated manufacturing process. Bids for this significant tender are due by December 24, 2025.

This solar module procurement is just one piece of a much larger 97 GW centralized program by PowerChina. The initiative also includes tenders for 35 GW of wind turbines and another 31 GW of solar inverters. The inverter tender is further segmented to cover a range of applications, from large-scale integrated cabinet inverters (8 GW) to powerful string inverters for commercial and utility use (20 GW), and smaller string inverters for distributed generation (3 GW). The sheer volume of this program highlights the immense scale of the raw materials and advanced manufacturing machines required to meet China’s renewable energy targets.
To put the scale of this tender into a global perspective, 31 GW is a monumental figure that dwarfs the renewable energy ambitions of many countries. For comparison, the entire Panama solar tender is preparing for its 2026 auction, while nations like Egypt plan for 12 GW of renewables and recent solar tenders in Algeria aim for 3 GW. PowerChina’s procurement alone for a single year’s projects exceeds the entire renewable capacity of many nations, demonstrating its dominant role in the global energy transition.
The procurement will establish framework agreements with a shortlist of suppliers, who will then be selected for specific projects through a secondary competitive process. This move provides PowerChina with supply-chain stability and pricing security for its 2026 project pipeline.
