Written summary
LONGi Solar is a Chinese manufacturer headquartered in Xi'an, Shaanxi province, founded in 2000. The company holds BloombergNEF Tier 1 PV module status confirmed across Q2 and Q3 2025 and Q1 2026, and received its 25th consecutive AAA rating in PV Tech's PV ModuleTech Bankability Report for Q1 2026. Annual module shipments are targeting approximately 80 GW, with back-contact (BC) module shipments alone having already surpassed 14 GW, placing LONGi among the top two global module suppliers by cumulative volume. Sunlike Solar Co., Ltd is a Chinese manufacturer based in Wuxi, Jiangsu, established in 2010. The company reports a production capacity of approximately 2 GW per year across cells and modules and does not appear on BloombergNEF's Tier 1 lists, representing a substantial gap in institutional standing. On every measure of bankability and global footprint, LONGi holds a decisively stronger position.
LONGi's product range addresses residential rooftop, commercial and industrial, and utility-scale ground-mount applications. The company has been actively shifting its lineup from TOPCon toward its proprietary HPBC back-contact technology, with BC modules targeted to account for more than 65% of total shipments going forward; mainstream BC module power ratings run around 650-655 W. Sunlike Solar offers both P-type and N-type monocrystalline and polycrystalline cells and modules, covering output ranges from roughly 200 W to 750 W, primarily targeting residential and smaller commercial buyers. The availability of M10 and G12 cell formats indicates the company tracks mainstream technology directions, but its limited scale means that independent long-term field performance data is sparse.
For a typical international buyer - whether a residential installer, a C&I developer, or a project financier - LONGi Solar is the clear default choice, backed by verified bankability, a global warranty and service infrastructure, and leading cell technology. Sunlike Solar may be a viable option for cost-driven or niche procurement, but buyers should conduct thorough due diligence on warranty terms and the manufacturer's financial stability before committing to significant volumes. The two brands are not interchangeable at institutional or utility scale.
