Gamko New Energy vs Jinko Solar - solar panel manufacturer comparison

Jinko Solar, founded in 2006 and headquartered in China, is the world's largest solar module manufacturer by shipment volume, having delivered 92.9 GW of modules in 2024 alone and surpassing a cumulative 350 GW of global installations by mid-2025. With over 33,800 employees, a module production capacity of 130 GW, and a listing on the New York Stock Exchange, Jinko holds confirmed Tier 1 bankable status from BloombergNEF and sells into more than 190 countries. Gamko New Energy, founded in 2008 and also based in China, is a considerably smaller manufacturer - with 201 to 300 employees and an annual production capacity of 1.2 GW. It does not carry a Tier 1 bankability rating and is not publicly listed, positioning it firmly among niche second-tier suppliers.

On the technology side, Jinko's portfolio is led by N-type TOPCon cells, which account for 39.45% of its 545-model lineup. Its modules reach a maximum efficiency of 24.8%, carry an average temperature coefficient of Pmax at -0.308%/°C, and include a 31.93% share of bifacial products, with an average warranty of approximately 28.5 years. This profile makes Jinko well suited to utility-scale ground-mount projects, large commercial and industrial rooftop installations, and any project structure requiring bankable module supply for project finance. Gamko New Energy's 255-model catalog is predominantly PERC-based (50.98%), though the company achieves a peak module efficiency of 24.14%. Its most distinctive characteristic is an exceptionally high bifacial share of 81.18% - more than double Jinko's bifacial ratio - and it offers a 30-year average product warranty, longer than Jinko's. These traits make Gamko a credible option for bifacial ground-mount installations, agrivoltaic projects, and residential installs where a longer warranty period is a key commercial differentiator.

For international buyers choosing between the two, Jinko Solar is the lower-risk choice for any project requiring lender approval, EPC bankability requirements, or long-term performance guarantees backed by a financially stable, publicly traded counterparty. Gamko New Energy may appeal to cost-sensitive buyers or niche integrators seeking a heavily bifacial portfolio with an extended warranty, provided they conduct thorough due diligence on local after-sales support and supply chain continuity in their target market.
