## Summary

GCL is a Chinese manufacturer operating as GCL System Integration (GCL SI), the module arm of the vertically integrated GCL Group, which has been producing polysilicon wafers and cells for over two decades. The company holds consistent BloombergNEF Tier 1 status and, based on 2024 shipment data, ranks among the top ten module suppliers globally with an estimated annual module capacity in the range of 25-30 GW and a 52% year-on-year shipment increase between 2023 and 2024. Sunova Solar is a smaller Chinese manufacturer that achieved BloombergNEF Tier 1 listing in Q3 2023 and carries a CCC+ bankability rating from PV Tech, with its subsidiary Thornova Solar also appearing on the BNEF Tier 1 list in Q1 2026; its annual production capacity is reported at approximately 5.5-6.5 GW. In terms of institutional footprint and raw market scale, GCL holds a clear advantage.

GCL's product range is broad, anchored by n-type TOPCon modules under its LOTUS and GEMINI series, including large-format bifacial panels up to 700 W built on 210 mm wafers - well suited for utility-scale ground-mount and commercial C&I projects alike. The group has also commissioned a 1 GW perovskite module factory in 2025, signaling long-range technology investment. Sunova has staked its differentiation on HJT (heterojunction) technology, with modules exceeding 700 Wp that deliver a low temperature coefficient and strong bifacial performance, making them a compelling option for high-irradiance sites and projects where long-term energy yield matters more than upfront cost.

For most international buyers - particularly those procuring for utility or commercial projects - GCL is the lower-risk default given its supply-chain depth, broad distribution, and bankability track record. Sunova is a well-founded choice where HJT performance characteristics are the deciding factor. In terms of financial bankability, the two brands are broadly interchangeable for lender purposes, though GCL's larger scale reduces supply-continuity risk on large orders.
