## Summary

Tongwei is a Chinese conglomerate headquartered in Chengdu that originated in the feed and chemicals industries before becoming one of the world's largest solar cell and module manufacturers, with annual production capacity now around 85 GW. It holds Tier 1 status from BloombergNEF and top bankability ratings from PV ModuleTech, and it was one of only two companies in the global top 10 to earn maximum scores across every category of the 2025 Kiwa PVEL Reliability Scorecard. Vikram Solar, by contrast, is an Indian manufacturer based in Kolkata that also carries BloombergNEF Tier 1 status and strong PVEL recognition, but operates at a much smaller scale, with nameplate capacity of roughly 4.5 GW following a recent 1 GW expansion at its Falta facility. In terms of institutional footprint and sheer manufacturing scale, Tongwei clearly has the stronger position.

Tongwei's product lineup centers on TOPCon technology, including its newer TNC3.0 series reaching 770 W and 24.8 percent efficiency with bifaciality above 90 percent, aimed primarily at utility-scale and commercial and industrial projects, alongside some shingled panels for residential use. Vikram Solar runs a more diversified technology mix spanning PERC, HJT, and a growing TOPCon line branded Hypersol, with modules ranging from 380 W to 735 W, which lets it serve both rooftop residential and larger ground-mount installations, with particular emphasis on the Indian market and the Make in India initiative.

For a typical international buyer, Tongwei is generally the more accessible default given its global distribution scale and established presence in supply chains serving Europe and other export markets, making it a reliable choice for large-scale deployments. Vikram Solar remains a credible, bankable alternative, especially attractive to buyers seeking supply chain diversification outside China, though its footprint outside India and select export markets is comparatively limited. Both brands are considered financeable and reliable, but they are not fully interchangeable given the gap in scale and regional availability.
