Growatt vs Jinko Solar - solar panel manufacturer comparison

Growatt, founded in 2010 in China, is primarily recognized in the industry as a leading inverter and battery storage manufacturer rather than a solar panel producer. Its panel catalog contains a single module rated at 150 Wp using PERC cell technology, with an efficiency of 18.6% and a temperature coefficient of -0.42%/°C; the company does not hold Tier 1 bankable status. Jinko Solar, founded in 2006 and listed on the NYSE, occupies a fundamentally different position - it is currently the world's largest solar module manufacturer by shipment volume, with a declared production capacity of 130 GW and a workforce of over 33,800 employees. Tier 1 bankable and publicly traded, Jinko holds approximately 13% global market share as of 2025 and has surpassed 300 GW in cumulative shipments, cementing its standing as a benchmark supplier for project finance and large-scale procurement.

Jinko Solar's panel portfolio spans 545 modules, with an average power output of 511 Wp and a maximum of 735 Wp. The dominant cell technology is TOPCon (N-type), which accounts for roughly 39% of the portfolio and delivers a superior temperature coefficient of -0.308%/°C - a meaningful advantage over Growatt's -0.42%/°C in warm or high-irradiation environments. Maximum module efficiency reaches 24.8% against a portfolio average of 22.0%. Approximately 32% of Jinko's lineup consists of bifacial modules, and the average product warranty extends to roughly 28.5 years. These attributes make Jinko panels well suited for utility-scale ground-mount projects, large commercial and industrial rooftop installations, and residential rooftop systems where energy yield per square meter is a priority. Growatt's single 150 Wp PERC module is better aligned with off-grid, portable, or small standalone applications and does not compete meaningfully in the mainstream grid-tied segment.

For international buyers evaluating the two as module suppliers, Jinko Solar is the clear choice across virtually all project types. Its Tier 1 status, NYSE listing, proven manufacturing scale, advanced TOPCon technology, and comprehensive product range provide the performance benchmarks and financial assurances required by lenders, EPCs, and independent power producers. Growatt remains a credible and cost-competitive brand in the inverter and BESS space, but its current panel offering is too limited in scope and technology generation to serve as a viable alternative to Jinko Solar for any significant grid-connected installation.
