JA Solar vs Loom Solar - solar panel manufacturer comparison

JA Solar and Loom Solar represent fundamentally different tiers of the global solar manufacturing landscape. JA Solar, founded in 2005 and headquartered in China, is one of the world's largest PV module producers, with a production capacity exceeding 100 GW, a workforce of over 37,000 employees, and a confirmed Tier 1 bankable status from S&P Global Commodity Insights. Listed on the Shenzhen Stock Exchange, the company has shipped close to 300 GW cumulatively and operates across 178 countries through 16 overseas subsidiaries. Loom Solar, by contrast, was founded in 2018 in Faridabad, India, employs between 100 and 500 people, and operates a 300 MW production facility - roughly 300 times smaller than JA Solar's capacity. Loom Solar does not hold Tier 1 status and is primarily active in the Indian domestic market and a handful of export destinations.

On the technology side, JA Solar's portfolio of over 524 panel models spans PERC (its dominant cell technology at over 52% of the lineup) and TOPCon, reaching a maximum efficiency of 24.4% and a peak output of 740 Wp, with an average temperature coefficient of -0.32%/°C. Nearly 44% of its portfolio is bifacial, making it well-suited for utility-scale ground-mount projects, commercial C&I rooftop installations, and high-density residential systems. Loom Solar manufactures mono-PERC, shingled, and bifacial panels with outputs reportedly up to 730 Wp, primarily targeting residential rooftop installs and small off-grid systems for Indian homeowners and small businesses. Its bundled inverter-plus-panel offerings and extensive domestic dealer network of over 10,000 partners are core strengths within the Indian market.

For international buyers - particularly those sourcing for European, North American, or large-scale Asian markets - JA Solar is the clear choice: it offers a mature, bankable product range, deep technical documentation, reliable supply chains, and warranties averaging nearly 28 years. Loom Solar is a credible and growing player for India-focused residential and small commercial deployments, but lacks the global infrastructure, Tier 1 certification, and product data depth required for buyers operating outside the Indian market.
