Jinko Solar vs MY Solar - solar panel manufacturer comparison

Jinko Solar, founded in China in 2006 and listed on the NYSE, is one of the world's leading solar module manufacturers with a production capacity of 130 GW and over 33,000 employees. The company holds Tier 1 bankable status under BloombergNEF classification and has been recognized as the most bankable PV brand for ten consecutive years, reaching a AAA rating in the PV Tech ModuleTech Bankability Report. MY Solar is a considerably smaller manufacturer with no Tier 1 bankable certification, offering a portfolio of 140 panels compared to Jinko's 545. While both are China-based producers, Jinko Solar's scale, financial standing, and global distribution network place it in a fundamentally different market tier, with cumulative shipments exceeding 370 GW worldwide.

From a technology standpoint, Jinko Solar leads with N-type TOPCon cells representing 39.4% of its portfolio, delivering a maximum module efficiency of 24.8% and an average efficiency of 22.0%, paired with an average temperature coefficient of -0.308%/°C. This performance profile makes Jinko panels well-suited for residential rooftop installs where roof area is constrained, large utility-scale ground-mount projects, and commercial C&I applications that require bankable suppliers for project financing. MY Solar's portfolio is dominated by PERC technology at 57.9% of panels, with a maximum efficiency of 23.82% and an average efficiency of 19.87%, along with a less favorable temperature coefficient of -0.333%/°C. MY Solar's higher share of bifacial panels - 38.6% versus 31.9% for Jinko - could appeal to buyers targeting open ground-mount installations where rear-side irradiance adds meaningful yield. However, MY Solar's lower average output of 418 Wp, compared to Jinko's 511 Wp, reflects a portfolio oriented toward smaller and mid-range systems rather than high-density commercial or utility deployments.

For international buyers - particularly in European markets requiring bankable manufacturers for project financing, insurance underwriting, or subsidy eligibility - Jinko Solar is the clearly lower-risk choice, supported by its Tier 1 status, an average warranty of 28.5 years, and a deep track record across diverse climates and project types. MY Solar may attract cost-sensitive buyers willing to accept lower average efficiency and the absence of Tier 1 certification, but due diligence on long-term financial stability and after-sales support is strongly advisable before committing to larger procurement volumes.
