## Summary

ET Solar and Jinko Solar are both Chinese photovoltaic module manufacturers with nearly identical founding timelines - ET Solar was established in 2005 and Jinko Solar in 2006 - yet the two companies occupy vastly different positions in the global solar industry. Jinko Solar has grown into the world's largest solar module manufacturer by shipment volume, reporting a production capacity of 130 GW and a workforce of over 33,000 employees, with shares listed on the NYSE and a confirmed Tier 1 bankable status that underpins project financing across institutional and utility markets worldwide. ET Solar, by contrast, remains a substantially smaller manufacturer with no Tier 1 recognition, a limited product portfolio of 10 panel models, and a history of reported financial difficulties that have raised questions about long-term warranty support in some markets.

In terms of technology and portfolio breadth, Jinko Solar holds a clear advantage. Its 545-model lineup spans both legacy PERC and advanced N-type TOPCon cell technologies, with the TOPCon-based Tiger Neo series reaching a maximum efficiency of 24.8% and a portfolio average of 22.0%. A temperature coefficient of -0.308%/°C further reduces thermal losses compared to ET Solar's -0.34%/°C. Jinko's top panel output reaches 735 Wp, suited to large-format utility-scale ground-mount and commercial C&I installations where watt-per-module economics matter. ET Solar's portfolio is entirely PERC-based, with a maximum efficiency of 21.4%, an average of 20.99%, and a top output of 555 Wp - a competent but dated profile that fits smaller residential rooftop installations where cutting-edge cell technology is less critical.

For international buyers choosing between the two, Jinko Solar is the stronger option across virtually all project types. Its Tier 1 bankable status, superior TOPCon technology, higher efficiency ceiling, better temperature performance, longer average warranty of approximately 28.5 years versus ET Solar's 27.5 years, and 11 consecutive PVEL Top Performer recognitions make it a credible choice from residential to utility scale. ET Solar may be considered where local availability and lower upfront cost are the primary drivers, but buyers in any segment should carefully assess warranty service risk and the manufacturer's limited market footprint before committing.
