Written summary
Resun Solar is a Chinese module manufacturer headquartered with factories in Changzhou and Suzhou, Jiangsu province, operating since 2005 and therefore with roughly two decades of manufacturing history. Reported annual production capacity ranges from about 1 GW to 5 GW depending on the source, placing it in the mid-tier of Chinese module makers. The company holds TUV, CE and UL certification and PID-free approval from PI-Berlin, but it does not consistently appear on public Tier 1 bankability lists such as BloombergNEF's, suggesting weaker standing for lenders financing large-scale projects. Talesun, a subsidiary of the Fortune Global 500 Zhongli Group, was established in 2009-2010 in Suzhou and operates at considerably larger scale, with factories in China and Rayong, Thailand; cumulative module shipments have surpassed 40 GW and the company has repeatedly been named to BloombergNEF's Tier 1 list, giving it a clearly stronger institutional footprint and bankability.
Resun's catalog spans poly and mono modules, including half-cell, full-cell and smaller-format panels from 5W to 720 W, suited to both ground-mount MW-scale projects and residential rooftop systems, including World Bank rural electrification programs it has supplied for over 15 years. Talesun leans more heavily into current N-type cell technology - TOPCon, HJT and BC - with modules rated from 500 W to 735 W, serving residential, commercial and utility-scale segments alike, and it additionally runs its own project development and EPC services.
For a typical international buyer, Talesun is the safer default choice given its confirmed Tier 1 status, larger production scale, and more current TOPCon technology base. Resun Solar remains a reasonable option where price and flexibility on smaller order volumes matter most, but it warrants closer bankability diligence before committing to larger, debt-financed installations.
