Jinko Solar vs Solarspace - solar panel manufacturer comparison

Jinko Solar and Solarspace are both Chinese Tier 1 solar module manufacturers, but they occupy markedly different positions in the global market. Jinko Solar, founded in 2006 and listed on the NYSE, is the undisputed global market leader, with a production capacity of 130 GW and over 33,800 employees. In the first half of 2025, JinkoSolar shipped approximately 41 GW of modules, securing the top spot worldwide. The company holds roughly 13% of the global module market and has surpassed 300 GW of cumulative installations. Solarspace, founded in 2011, is a mid-sized but growing manufacturer with a capacity exceeding 60 GW and a workforce of over 6,000. It maintains Bloomberg NEF Tier 1 bankable status and has been expanding its overseas presence, including participation in a notable 6.2 GW batch of international orders alongside Jinko and Arctech in late 2025. Jinko's portfolio spans 545 module models versus Solarspace's 82, reflecting the gap in scale and geographic reach.

Technologically, the two manufacturers take different approaches. Jinko Solar leads with its TOPCon cell technology - featured in about 39% of its portfolio - achieving a maximum module efficiency of 24.8% and a world-record TOPCon cell efficiency of 27.79% verified in independent testing. Only around 32% of Jinko's lineup is bifacial, making many of its products well suited to residential rooftop installations where rear-side gain is limited. Solarspace, by contrast, has built its portfolio almost entirely around bifacial modules - 92.7% of its lineup - combined with N-type cell technology covering nearly 70% of its range. Its average temperature coefficient of -0.299%/°C edges out Jinko's -0.308%/°C, a modest but measurable advantage in warm climates. Solarspace also offers a longer average product warranty at 29.6 years versus Jinko's 28.5 years, and its average module power of 539 Wp slightly exceeds Jinko's 511 Wp average.

For international buyers, Jinko Solar is the lower-risk choice for residential, commercial C&I, and large utility-scale projects where brand recognition, financing bankability, and global after-sales support are priorities. Solarspace presents a compelling alternative for ground-mount utility-scale projects where bifacial gain over high-albedo surfaces can be fully captured, and where buyers are comfortable working with a newer but financially credible brand offering competitive specifications at potentially attractive price points.
