## Summary

Astronergy is a Chinese cell and module manufacturer headquartered in Haining, founded in 2006 as part of the CHINT Group. It holds Tier 1 status per S&P Global Commodity Insights and appears on BloombergNEF's bankability list, with annual module production capacity reported in the range of 56-76 GW during 2024-2025 and cumulative global shipments exceeding 150 GW. Vikram Solar, founded in 2005 and headquartered in Kolkata, West Bengal, is India's largest module manufacturer by production volume, also carrying BloombergNEF Tier 1 status and a Top Performer rating in PVEL's reliability scorecard; its capacity grew from about 4.5 GW in early 2025 to roughly 9.5 GW after the Vallam plant came online later that year. In terms of sheer global scale and institutional track record, Astronergy currently has the stronger footprint.

Both manufacturers center their current lineups on n-type TOPCon technology. Astronergy's ASTRO N7, N7 Pro and N8 series span lightweight residential modules through high-wattage bifacial panels for utility-scale and C&I projects. Vikram Solar's newer Hypersol series covers similar TOPCon bifacial applications from rooftop to utility scale, while its Paradea line still offers mono PERC bifacial modules for buyers not requiring the latest cell technology. Geographically, Vikram Solar is more deeply rooted in the Indian market, whereas Astronergy has broader international distribution, including a strong presence in Europe.

For buyers outside India, Astronergy is typically the easier default given its larger scale, longer export track record and broader financing recognition, while Vikram Solar is a strong choice where local Indian manufacturing, government incentive eligibility, or regional supply chains matter. On core module technology the two brands are largely comparable today.
