## Summary

DAH Solar is a Chinese manufacturer founded in 2009 in Hefei, with a workforce of over 2,000 employees and a production capacity of 10 GW. The company holds confirmed BloombergNEF Tier 1 bankable status, maintained consistently through multiple quarters of 2025, which signals financial stability and broad project financing eligibility. Techwise Solar, by contrast, does not hold Tier 1 status and operates at a much smaller scale - approximately 1 GW of annual production capacity - positioning itself primarily as a cost-competitive or ODM/OEM-oriented supplier rather than a globally recognized branded manufacturer. Both companies are headquartered in China and both lead their respective portfolios with TOPCon cell technology, though DAH Solar applies it across 79.6% of its panel lineup versus 69.5% for Techwise Solar.

DAH Solar's technology portfolio stands out for its exceptionally high bifacial share - 87.05% of panels are double-sided - making it a natural fit for utility-scale ground-mount projects, agrivoltaic installations, and large commercial rooftops where albedo gains boost overall yield. Its average module efficiency of 22.10% (maximum 23.34%) and a favorable temperature coefficient of -0.299%/°C support strong performance in warm-climate or large-scale deployments. The average product warranty across its 363-panel range is 29.4 years. Techwise Solar offers a narrower bifacial share of 49.4% and a slightly weaker temperature coefficient of -0.317%/°C, but its maximum rated efficiency reaches 23.8% and average power output of 530 Wp edges ahead of DAH Solar's 520 Wp average - suggesting competitive high-power modules suitable for space-constrained residential rooftop installs and smaller commercial C&I projects where per-watt cost is the primary driver.

For international buyers evaluating the two, DAH Solar is the lower-risk choice for utility-scale, commercial, or any project requiring bank financing, EPC contractor approval, or long-term performance warranties - its Tier 1 status and 10 GW manufacturing scale provide the institutional confidence those projects demand. Techwise Solar may appeal to experienced installers or developers working on budget-sensitive residential or small commercial projects who are comfortable sourcing from a smaller, non-Tier-1 supplier and can independently verify product quality through certification documents and spot testing.
