Longi Solar vs Vikram Solar - solar panel manufacturer comparison

Longi Solar is a Chinese manufacturer headquartered in Xi'an, founded in 2000, and consistently ranked as a BloombergNEF Tier 1 module producer - a designation that confirms bankability and eligibility for non-recourse project financing. The company's scale is exceptional: it shipped approximately 39.57 GW of modules in the first half of 2025 alone, and its proprietary back-contact cell production capacity is targeted at 50 GW. Longi also holds the distinction of being the only major module supplier currently carrying net cash rather than net debt, which adds an additional layer of financial credibility for long-term project developers. Vikram Solar is an Indian manufacturer founded in 2006 and headquartered in Kolkata, also listed on the BloombergNEF Tier 1 register. After commissioning its 5 GW Vallam facility in Tamil Nadu in late 2025, the company's total module manufacturing capacity reached approximately 9.5 GW, with ambitions to reach 17.5 GW by 2027. In terms of institutional footprint and global reach, Longi Solar is the clear leader.

Longi Solar's product lineup centers on the Hi-MO series. TOPCon-based modules accounted for roughly 70% of shipments in H1 2025, while the company's proprietary HPBC 2.0 back-contact technology - used in the Hi-MO 9 - has demonstrated module efficiencies above 24% in mass production and outperformed standard TOPCon in multiple independent field studies measuring energy yield and levelized cost of energy. These modules address utility-scale, C&I, and residential applications alike. Vikram Solar's Hypersol series targets C&I and utility-scale buyers with n-type bifacial TOPCon modules in the 605-630 W range and efficiencies between 22.38% and 23.30%. For residential installations the company offers the Suryava HJT series, a bifacial heterojunction module with efficiency above 23%, reflecting a deliberate two-technology strategy.

For most international buyers, Longi Solar is the lower-risk default - its volume, supply chain depth, and European distribution infrastructure make procurement and warranty support more straightforward. Vikram Solar is a legitimate Tier 1 alternative and a genuinely compelling option where buyers require non-Chinese-origin panels, for example under procurement rules tied to government tenders or domestic content requirements. Both brands are technically comparable at the Tier 1 level, so the decision often turns on supply availability, origin preferences, and project-specific financing requirements rather than on any fundamental quality gap.
