Jinko Solar vs Top Solar - solar panel manufacturer comparison

Jinko Solar and Top Solar occupy entirely different tiers of the global solar PV industry. Jinko Solar was founded in 2006, is headquartered in China, and is listed on the New York Stock Exchange (NYSE). With a production capacity of 130 GW, a workforce of over 33,800 employees, and confirmed Bloomberg Tier 1 bankability status, Jinko ranks among the top two or three module manufacturers worldwide by shipment volume - having recorded 41.84 GW of module shipments in H1 2025 alone. The company has an extensive portfolio of 545 panel models and holds multiple world records at the cell level, including a 27.79% TOPCon cell efficiency. Top Solar, by contrast, is a small Chinese manufacturer with over 200 employees and a production capacity below 1 GW. Its catalog, as currently documented, consists of a single 150 Wp module based on back contact cell technology. Top Solar does not appear on Bloomberg Tier 1 lists and has no publicly verifiable bankability rating.

Jinko Solar's strength lies in its breadth and technical depth. Its TOPCon N-type modules - representing nearly 40% of its catalog - deliver an average efficiency of approximately 22% and a best-in-class temperature coefficient of -0.31%/°C, limiting performance losses during hot weather. Nearly 32% of Jinko's lineup consists of bifacial modules, making the brand well suited to utility-scale ground-mount projects, large commercial C&I rooftop installations, and high-yield residential rooftop installs where long warranties (averaging over 28 years) and financing security matter. Top Solar's 150 Wp back contact panel targets a narrow niche: off-grid systems, marine and RV applications, campsites, and small autonomous energy setups where low unit power and compact form factor take priority over maximum efficiency - its 18.6% module efficiency and -0.42%/°C temperature coefficient are both below the industry mainstream.

For buyers selecting between the two for grid-tied residential or commercial projects, Jinko Solar is the clear choice given its scale, verified bankability, diverse product range, and demonstrated long-term reliability. Top Solar is not a realistic alternative for mainstream grid-connected installations but may serve integrators sourcing low-wattage modules for off-grid or specialty applications where Jinko's larger format panels are simply not applicable.
