## Summary

DAH Solar and EGing PV are both Tier 1 BNEF-certified Chinese solar module manufacturers, but they diverge considerably in scale, technology focus, and financial health. DAH Solar, founded in 2009 in Hefei, China, operates with a declared production capacity of 10 GW and a broad portfolio of 363 modules, establishing it as the larger and more technologically advanced of the two. EGing PV, founded earlier in 2003 in Changzhou and publicly listed on the Shenzhen Stock Exchange (SZSE), fields a narrower lineup of 131 modules. Both carry Tier 1 bankability status, but EGing PV's financial position has deteriorated sharply - in 2024 the company reported a year-on-year revenue decline of over 57% and a net loss exceeding RMB 2.09 billion, raising legitimate concerns about its ability to honor long-term warranty obligations.

DAH Solar's portfolio is dominated by TOPCon cell technology (79.6% of its lineup), with a maximum module efficiency of 23.34% and an average portfolio efficiency of 22.1%. Its bifacial module share reaches 87%, its maximum power output tops out at 725 Wp, and its average temperature coefficient of Pmax stands at -0.299%/°C - a favorable figure for warm or variable climates. The company's signature Full-Screen frameless modules, independently validated by TüV Nord as generating 11.5% more energy than conventional framed counterparts, make a strong case for utility-scale ground-mount and commercial C&I applications. EGing PV's portfolio remains predominantly PERC-based (74.8%), with a maximum efficiency of 22.45% and a portfolio average of 20.9%. Only 39% of its modules are bifacial, and the average temperature coefficient of -0.336%/°C is less competitive under high-temperature operating conditions. On the positive side, EGing PV earned recognition as a top performer across six test categories in the PVEL 2024 PV Module Scorecard, indicating consistent manufacturing quality at the cell and module level.

For international buyers comparing the two, DAH Solar offers the stronger overall value proposition for projects where energy yield, technology longevity, and manufacturer stability are priorities - whether residential rooftop, utility-scale, or commercial C&I. Its higher average power output (520 Wp vs. 504 Wp), superior efficiency, better temperature coefficient, and longer average product warranty (29.4 vs. 26.9 years) all point in that direction. EGing PV may remain price-competitive for budget-sensitive residential installations where PERC technology is sufficient, but its constrained technology roadmap and current financial difficulties represent meaningful risk for long-horizon projects.
