Epax Solar vs Jinko Solar - solar panel manufacturer comparison

Epax Solar GmbH is a small, owner-managed company headquartered in Deggendorf, Germany, founded in 2019 with a reported workforce of just 1-10 employees. Critically, Epax Solar is not a panel manufacturer - it operates as a B2B wholesale distributor of photovoltaic components, supplying solar installers and project developers across Germany and broader Europe. The company holds no proprietary panel portfolio (no product data is recorded in the database). Jinko Solar, by contrast, is one of the world's largest solar manufacturers, founded in China in 2006 with over 33,800 employees and an annual production capacity of 130 GW. The company is publicly listed on the NYSE, carries Tier 1 bankable status, and offers a catalogue of 545 panel models with a maximum output of 735 Wp and a peak module efficiency of 24.8%. TOPCon is the leading cell technology in its lineup (approximately 39% of the portfolio), with an average panel efficiency of around 22% and an average temperature coefficient of Pmax at -0.31%/°C. In 2025, Jinko set a world record for n-type TOPCon cell efficiency at 27.79%, independently verified by Germany's ISFH institute.

Epax Solar's role as a European distributor may be relevant for installers or wholesalers seeking a logistics partner with access to PV components via pallet or container deliveries and a broad European supplier network - but it does not supply its own manufactured panels for end-user installations. Jinko Solar, by comparison, serves the full spectrum of deployment scenarios: residential rooftop installs benefit from its wide power range and long warranty averaging approximately 28.5 years; utility-scale ground-mount projects gain from its production scale, bankability, and low degradation rates (0.4% annually for N-type modules); and commercial C&I projects are well served by its high-efficiency TOPCon lineup reaching up to 735 Wp per module. The company has also achieved 11 consecutive years as a PVEL Top Performer and surpassed 300 GW of cumulative global installations.

For international buyers choosing between the two, the comparison is fundamentally asymmetric - Epax Solar does not manufacture panels and cannot be evaluated as a module supplier. Jinko Solar is the only party here offering a tangible product portfolio, backed by Tier 1 bankability, a proven efficiency roadmap, and global service reach. Buyers in Europe or elsewhere evaluating Jinko should focus on its TOPCon Tiger Neo series, which offers a strong balance of power output, efficiency, warranty terms, and competitive pricing relative to premium-tier competitors.
