Jinko Solar vs Resun Solar - solar panel manufacturer comparison

Jinko Solar, founded in 2006 and headquartered in China, is one of the world's largest solar module manufacturers, listed on the NYSE and holding confirmed Tier 1 bankable status. The company employs more than 33,800 people and operates a production capacity of 130 GW per year, supplying residential, commercial, and utility-scale markets across six continents with a portfolio of 545 panel models. Resun Solar, also founded in China a year later in 2007, operates at a considerably smaller scale with a reported production capacity of 1 GW and a focused lineup of 28 models. Resun does not appear on published Tier 1 bankability lists, but the company holds TUV and PI-Berlin certifications and has established a regional presence in Europe - including a warehouse and office in Poland, the Netherlands, and the UK - positioning itself as an accessible mid-tier supplier for the European market.

Jinko Solar's broad portfolio includes flagship N-type TOPCon modules reaching a maximum panel efficiency of 24.8% and a peak output of 735 Wp, with TOPCon accounting for 39.4% of the product range. Eleven consecutive PVEL Top Performer designations and multiple world records in TOPCon cell efficiency reinforce Jinko's suitability for utility-scale ground-mount projects and large commercial C&I installations where long-term reliability and bankability are non-negotiable. Average product warranty across the portfolio stands at approximately 28.5 years. Resun Solar has committed its entire lineup to TOPCon technology, achieving a maximum efficiency of 22.94% and a peak output of 590 Wp. Notably, Resun offers a better average temperature coefficient (-0.293%/°C vs. -0.308%/°C for Jinko), a higher proportion of bifacial panels (42.9% vs. 31.9%), and a uniform 30-year warranty across all products - a technically competitive combination well suited to residential rooftop installs and small-to-medium commercial projects.

For international buyers, the decision hinges primarily on project scale and financing requirements. Jinko Solar is the default choice wherever Tier 1 bankability, global supply chain depth, or project finance is involved - particularly for utility-scale and large C&I developments. Resun Solar offers a focused but technically solid TOPCon lineup at a smaller scale; its European distribution network makes it a practical option for cost-sensitive residential or light commercial buyers in Poland and neighboring markets, provided that local distributor availability and warranty enforcement terms can be confirmed in advance.
