Longi Solar vs Sunova - solar panel manufacturer comparison

LONGi Solar is a Chinese manufacturer headquartered in Xi'an, Shaanxi Province, founded in 2000 and now one of the largest solar module companies in the world by annual shipment volume. The company holds Tier 1 status on the BloombergNEF bankability list and has consistently ranked among the global top two module suppliers. In 2025, LONGi reported cumulative back-contact module shipments exceeding 14 GW, with plans for 150 GW of total module capacity by 2026 - figures that place it in a different scale category from most peers. Sunova Solar, founded in 2016 and headquartered in Wuxi, Jiangsu Province, achieved Tier 1 status on the BloombergNEF list in Q3 2023 and carries a B bankability rating from PV Tech. By end of 2024 the company had shipped approximately 7.1 GW of modules cumulatively and operates roughly 10 GW of module production capacity across six plants, including a facility in Indonesia. LONGi has a substantially stronger institutional footprint, backed by a much longer operating history and deeper presence in project-financed utility-scale markets globally.

LONGi's current product strategy centers on its Hi-MO line, which spans residential, commercial, and utility segments. The flagship Hi-MO X10 and Hi-MO S10 series deploy the company's proprietary HPBC and HIBC back-contact cell technology - a hybrid combining HJT-style passivation with a full back-contact architecture - delivering module efficiencies up to 25% and product warranties of up to 30 years. These panels are offered under the dedicated EcoLife residential brand as well as to commercial and utility buyers. Sunova, which markets its modules under the Thornova brand for the US market, offers N-type TOPCon panels reaching up to 575 W at 22.2% efficiency alongside HJT bifacial modules in the 480 W class. The company serves installers and project developers across more than 20 countries, with a particular emphasis on bifacial double-glass designs suited to ground-mounted and flat-roof installations.

For a typical international buyer, LONGi is the safer default where maximum bankability, supply-chain depth, and long-term warranty support are critical - particularly for commercial or utility projects requiring non-recourse financing. Sunova is a credible Tier 1 alternative for buyers seeking a verified bankable option at a potentially more competitive price point, especially in residential and smaller C&I applications. The two brands are not interchangeable in institutional scale, but for a standard rooftop installation the practical performance gap is modest.
