GCL vs Waaree - solar panel manufacturer comparison

GCL, operating through its module subsidiary GCL System Integration (GCL-SI), is a Chinese manufacturer headquartered in Suzhou, Jiangsu Province, and is part of the GCL Group conglomerate founded in 1990. The company has maintained BloombergNEF Tier 1 status from 2021 through 2024, shipped approximately 16 GW of modules in 2023, and carries an annual nameplate module capacity of around 30 GW. Waaree Energies is headquartered in Mumbai, India, with roots going back to 1989 and solar module manufacturing beginning in 2007; it is now India's largest solar PV module producer and the largest solar module manufacturer outside China, with roughly 21 GW of module capacity. Waaree has held BNEF Tier 1 status for 39 consecutive quarters and in early 2025 became the first Indian manufacturer to earn PV Tech's coveted 'A' ModuleTech Bankability Rating. In production volume and established global scale, GCL holds the stronger institutional footprint, though Waaree's sustained bankability credentials have made it a fully credible alternative in supply-chain-sensitive procurement.

GCL's current product range is anchored by TOPCon technology - its GPC2.0 series offers 660 W output via a busbar-free OBB design with a notably low temperature coefficient, targeting utility-scale ground-mount installations and large commercial rooftops. The company is also pursuing perovskite cell development, positioning itself at the frontier of next-generation photovoltaics. Waaree's portfolio likewise centers on N-type TOPCon cells across several product series, but also extends into HJT modules and a back-contact TOPCon variant that reached 645 W at 23.88% efficiency - attractive for space-constrained residential and premium commercial rooftops. Waaree operates 1.6 GW of TOPCon module capacity in Texas, has added HJT capacity in Arizona, and is actively targeting Eastern European markets under the EU Net-Zero Industry Act from 2026 onward, backed by a 30-year performance warranty that exceeds the industry norm.

For procurement where volume and lowest cost per watt dominate - such as large utility tenders or cost-driven C&I portfolios - GCL's massive scale and unbroken Tier 1 history make it a reliable default. For European and US buyers navigating supply-chain diversification requirements, or seeking modules manufactured outside China, Waaree's growing international manufacturing footprint, 'A' bankability rating, and longer performance warranty represent a compelling non-Chinese option. The two brands address overlapping but distinct priorities: GCL excels on scale and price efficiency, while Waaree is better positioned where geographic manufacturing origin carries weight in the purchasing decision.
