JS Solar vs Sunlike Solar - solar panel manufacturer comparison

JS Solar is a Chinese manufacturer founded in 2004 and based in Yixing, Jiangsu Province, with production capacity reported at around 10 GW spanning solar cells, modules, and complete PV power stations. The company offers a broad catalog of panels certified to CE, IEC 61215, and IEC 61730 standards and exports to more than 100 countries, though independent sources do not place it on BloombergNEF's current Tier 1 bankable list. Sunlike Solar, also Chinese, was founded in 2010 and is headquartered in Wuxi, Jiangsu Province, with a smaller reported annual capacity of roughly 2 GW across cells and modules. Like JS Solar, Sunlike Solar does not appear on BloombergNEF's Tier 1 list, placing both brands in the broader mid-tier segment of the Chinese supply chain rather than among the most established global bankable names; JS Solar's considerably larger production scale and longer export track record give it a somewhat stronger institutional footprint.

Product-wise, JS Solar's lineup is wide-ranging, with power outputs spanning roughly 200 W to 670 W and an average panel efficiency around 20 percent (peaking near 22.4 percent), making it a flexible choice spanning residential rooftops to larger commercial installations, backed by a warranty averaging 25 years. Sunlike Solar focuses on a narrower but higher-efficiency range, with peak module efficiency reported at about 23.52 percent and output formats extending into the 700 W-plus class suited to utility-scale or large commercial arrays; it offers both legacy P-type and newer N-type cell architectures, and backs modules with a 15-year product warranty alongside a 25-year linear performance guarantee retaining at least 84.8 percent of nominal output.

For a typical buyer in 2025, the choice depends on priorities: JS Solar's larger manufacturing base, longer warranty terms, and wider certification footprint make it a somewhat safer default for buyers prioritizing long-term support and proven export history, while Sunlike Solar's higher peak efficiency and N-type cell options may appeal to buyers chasing marginally better performance in space-constrained installations. Neither brand carries full Tier 1 bankability status, so large-scale or financed projects should weigh that factor carefully regardless of which brand is chosen.
