Written summary
Huasun is a Chinese manufacturer founded in 2020 and headquartered in Xuancheng, Anhui province, built specifically around heterojunction (HJT) cell technology. It has appeared repeatedly on BloombergNEF's Tier 1 PV module manufacturer list, including the 2025 quarterly editions, and was named a Top Performer in Kiwa PVEL's 2025 PV Module Reliability Scorecard. Its HJT manufacturing base has reportedly scaled toward the 20 GW range with an announced target of 40 GW by the end of 2025, and cumulative global shipments passed 10 GW by late 2024, rising past 13 GW by mid-2025 according to company figures. Runergy is also a Chinese manufacturer, established in 2013, with a larger and more diversified footprint spanning PERC and n-type TOPCon cells and modules, plus heterojunction development; by the end of 2023 it had reported planned capacity around 63 GW for cells and 23 GW for modules, and it opened a 2 GW module plant in Alabama in 2024 to serve the US market. Runergy has maintained BloombergNEF Tier 1 status through 2024 and reports multi-year "Top Performer" and "Highest Achiever" ratings from Kiwa PVEL and RETC. On raw scale and geographic diversification, Runergy currently has the stronger institutional footprint, while Huasun's position rests more narrowly but deeply on HJT leadership.
Product-wise, Huasun concentrates almost entirely on HJT modules, marketed for both utility-scale ground mounts, such as large Chinese grid-connected HJT projects, and increasingly for premium residential and commercial rooftops in Europe, where its vertical bifacial HJT panels are positioned for high-yield, space-constrained installations. Runergy's catalog is broader, spanning budget-to-mainstream PERC modules alongside newer high-efficiency n-type TOPCon products, which it has verified through third-party labs like ISFH, making it a flexible supplier for utility-scale projects, commercial rooftops, and, through its US plant, domestic-content-sensitive American installations. Some Runergy-derived cells also appear under other sold brands, such as Hyperion, which has created some inconsistency in how its technology mix is described publicly.
For a typical 2025 buyer, the choice depends on priorities: Runergy's larger, more geographically diversified capacity and longer multi-year reliability track record make it a safer default for large-scale or US-based procurement, while Huasun is a reasonable choice for buyers specifically seeking HJT's typically higher bifaciality and low-light performance, especially in Europe. Both carry current Tier 1 and independent reliability recognitions, so neither should be considered a clearly inferior choice, but they are not simply interchangeable given their differing technology emphasis.
