Written summary
Longi Solar is a Chinese manufacturer headquartered in Xi'an, founded in 2000 and originally focused on monocrystalline silicon materials before becoming, by most industry counts, the world's largest producer of monocrystalline wafers and solar modules. Longi has repeatedly appeared on BloombergNEF's Tier 1 PV module list through 2025 and into Q1 2026, and it operates at a very large scale, with reported annual production capacity around 120 GW in 2025 and dedicated HPBC 2.0 back-contact cell capacity exceeding 50 GW. QN-SOLAR is a newer China-based manufacturer headquartered in Shanghai, launched its global PV business in 2022, and operates six manufacturing bases in China with a reported combined capacity of roughly 69 GW of cells and 39 GW of modules as of 2024; no independent BloombergNEF Tier 1 listing for QN-SOLAR was found in available sources. Longi therefore has the substantially stronger and longer-established institutional footprint.
Longi's product range spans premium monocrystalline modules for residential rooftops through to utility-scale ground-mount projects, built around its own HPBC (back-contact) and TOPCon cell technologies, and the company markets high module efficiencies (HPBC 2.0 reaching around 25.4 percent). QN-SOLAR's portfolio, by contrast, is described as covering around 50 panel models with an average efficiency near 21.4 percent, using TOPCon technology in part of its lineup, with panels commonly in the 380-460 W residential and commercial range; the company also references early-stage work in perovskite and hydrogen technologies, signaling longer-term R&D ambitions rather than current mainstream deployment.
For a typical buyer in 2025, Longi is the safer default given its longer track record, confirmed Tier 1 bankability, larger production scale, and higher-efficiency flagship technology, making it well suited to both residential and utility-scale projects where financing and long-term brand stability matter. QN-SOLAR can be a reasonable option for cost-sensitive residential or commercial installations, particularly where its TOPCon models are competitively priced, but buyers should independently verify warranty terms and project-specific bankability, since it lacks the same length of market history and confirmed Tier 1 status as Longi.
