Jinko Solar vs Solplanet - solar panel manufacturer comparison

Jinko Solar and Solplanet are both Chinese companies operating in the solar energy sector, but they occupy fundamentally different positions in the value chain. Jinko Solar, founded in 2006 and listed on the NYSE, is one of the world's largest solar module manufacturers with a production capacity of 130 GW and a workforce of over 33,000 employees. The company holds Tier 1 bankable status, reflecting strong financial standing and consistent manufacturing quality. Solplanet, by contrast, is the international brand of AISWEI Technology - a company with roots tracing back to its origins as a subsidiary of SMA and founded around 2007 - and is primarily an inverter, battery storage, and EV charger manufacturer. With only 127 employees and no solar panel portfolio of its own, Solplanet operates at a much smaller scale and in a different product category altogether.

Jinko Solar's panel portfolio of 545 models spans a wide range of applications. Its TOPCon-based modules - representing nearly 40% of its lineup - deliver a maximum panel efficiency of 24.8% and an average of 22.0%, with roughly 32% of the range consisting of bifacial designs suited to ground-mount and commercial rooftop installations. The average product warranty of approximately 28.5 years and a favorable temperature coefficient (average -0.308%/°C for Pmax) make Jinko modules competitive for residential rooftop installs, utility-scale ground-mount projects, and commercial C&I deployments worldwide. Solplanet's strengths lie in a growing inverter ecosystem - single-phase and three-phase hybrids, battery storage units, and monitoring solutions - with an increasingly active presence in European markets including Poland, where the brand distributes through partners such as Grodno SA and runs installer training programs.

For international buyers selecting between the two, the comparison is not straightforward since Solplanet does not manufacture solar panels. A buyer seeking high-efficiency, bankable modules from a volume manufacturer with a proven global track record will find Jinko Solar to be a well-established choice. A buyer building out a complete balance-of-system solution who needs an inverter brand with growing European logistics and support may find Solplanet's AISWEI-backed ecosystem worth evaluating - but not as an alternative panel supplier.
