## Summary

DAH Solar, founded in 2009 and headquartered in Hefei, China, and Vikram Solar, founded in 2005 in Kolkata, India, are both Tier 1 bankable module manufacturers with broadly comparable scale - 10 GW and 9.5 GW of annual production capacity respectively. DAH Solar employs over 2,000 people and has assembled a broad portfolio of 363 panel models, while Vikram Solar - publicly listed on India's NSE and BSE stock exchanges - counts approximately 1,895 employees and offers 143 panel models. Both companies have established international sales channels, with Vikram Solar active in over 30 countries including the US and Germany, and DAH Solar expanding aggressively in European and Australian markets. DAH Solar has secured consecutive placements on BNEF's Tier 1 list through 2025, reinforcing its bankability credentials for project finance.

The two manufacturers diverge most sharply in cell technology strategy. DAH Solar has transitioned nearly 80% of its portfolio to TOPCon cells, yielding a higher average module efficiency of 22.1% and a superior temperature coefficient of -0.299%/°C - a meaningful real-world advantage in variable-irradiance climates. Its proprietary "Full-Screen" frameless module design, independently validated by TÜV Nord with field-measured generation gains of up to 11.5%, positions DAH Solar as a strong fit for residential rooftop installs and commercial C&I projects where roof area is limited and soiling losses matter. Vikram Solar's portfolio remains PERC-dominated at over 70%, yet achieves a higher peak module efficiency of 23.66% and a higher average wattage of 552 Wp - attributes that reduce racking and wiring costs in utility-scale ground-mount projects. Vikram Solar's bifacial share stands at 81%, versus DAH Solar's 87%, and its average warranty term of 29.0 years closely matches DAH Solar's 29.4 years.

For international buyers choosing between the two, DAH Solar is the stronger option for efficiency-sensitive applications and rooftop installations in temperate climates, owing to its deeper TOPCon penetration and notably better thermal performance. Vikram Solar presents a compelling case for large-scale procurement in markets where supply chain diversification away from China is a policy or financing requirement, and its stock exchange listing adds a layer of financial transparency that lenders and institutional investors may value. Both carry equivalent Tier 1 bankability and near-identical long-term warranty commitments, making either a credible choice for well-structured solar investments.
