Thornova vs AIKO - solar panel manufacturer comparison

Thornova Solar is a Chinese manufacturer headquartered in Wuxi, Jiangsu Province, founded in 2016 under the Sunova Solar name and fully rebranded to its current identity by January 2025. The company holds BNEF Tier 1 bankability status (listed since August 2023) and a B-rating in the PVTech Bankability Report. Reported module production capacity stands at approximately 6.5 GW per year, with cumulative global shipments of 7.1 GW by end of 2024. AIKO Solar is a Shanghai-headquartered Chinese manufacturer with roots going back to 1996, also holding BNEF Tier 1 status, and has scaled annual production capacity to roughly 20 GW as of early 2025 across gigafactories in Yiwu, Foshan, Zhuhai, and other Chinese cities, with an R&D center in Freiburg, Germany. By production scale and institutional depth, AIKO occupies a noticeably larger footprint than Thornova.

Thornova's lineup centers on N-Type TOPCon technology, with a large-scale HJT program slated for later years. Its panels range from roughly 400 W to 720 W and include bifacial modules suited to commercial rooftops and utility-scale ground mounts; the Tangra M Pro line earned an "Overall Highest Achiever" designation in the RETC PVMI report and a Kiwa PVEL 2025 Top Performer award, confirming solid independent lab credentials. AIKO's defining differentiator is its N-Type ABC (All Back Contact) cell architecture, which places all electrical contacts on the rear surface, eliminating front-side shading losses. This technology underpins efficiency figures that have topped global rankings - AIKO announced a 24.4% mass-production module efficiency world record in June 2025. The Neostar series targets premium residential and commercial rooftops where roof area is limited, backed by a 30-year performance warranty with a 0.35% annual degradation rate after year one.

For buyers prioritizing maximum watts per square meter and willing to pay a modest premium, AIKO's ABC technology offers a confirmed advantage backed by independent lab results and installer surveys. Thornova is the stronger choice for cost-conscious buyers in utility and commercial segments needing a bankable, well-tested TOPCon product; its PVEL recognition keeps it credible in project-financed deals. The two brands are not interchangeable - AIKO leads on efficiency and warranty depth, while Thornova competes on value-per-watt for larger ground-mount installations.
