## Summary

Suntech is a Chinese manufacturer headquartered in Wuxi, founded in 2001 by Dr. Zhengrong Shi and once the world's largest crystalline-silicon module producer before filing for bankruptcy in 2013 and being acquired by Shunfeng International Clean Energy in 2014. Its BloombergNEF Tier 1 status has fluctuated over the years, with the company appearing and dropping off recent quarterly lists, so buyers should verify current standing before relying on it for project financing. Vikram Solar, by contrast, is an Indian manufacturer based in Kolkata, founded in 2005 by Gyanesh Chaudhary, which went public on the BSE and NSE in August 2025. It has consistently held BloombergNEF Tier 1 status and recently expanded manufacturing capacity to around 9.5 GW annually through upgrades at its Falta and new Vallam facilities. On institutional footing and current bankability, Vikram Solar currently holds the stronger position.

Both companies produce monocrystalline modules spanning residential rooftop, commercial and industrial (C&I), and utility-scale ground-mount applications. Vikram Solar has diversified into bifacial, multi-busbar, G12 half-cell, HJT and N-type cell technology with outputs from 395 W to 735 W, giving it flexibility across both distributed and large-scale projects. Suntech's legacy strength lies in conventional PERC-based silicon modules, and while the brand remains recognizable, its current product visibility is more limited than during its pre-2013 peak.

For a typical international buyer prioritizing financing certainty and access to newer cell technologies, Vikram Solar is the safer default choice given its steady Tier 1 track record and expanding capacity. Suntech retains brand recognition and a long manufacturing history, but its bankability status and current product lineup warrant closer due diligence before committing to a purchase.
