Catalogue against catalogue
An average over a catalogue describes the range a manufacturer publishes, not the module you would buy. A brand with two flagship panels and eighty older ones averages worse than one that has retired its back catalogue.

Written summary
Resun Solar is a Chinese module manufacturer based around Suzhou/Changzhou in Jiangsu province, operating under the Resun Solar and Restar Solar brands since roughly 2005-2007. The company states annual production capacity somewhere between 3 and 5 GW depending on the source, covering mono, poly, double-glass bifacial and BC-type modules across a wide power range up to 720 W. Available sources do not confirm Resun Solar's presence on BloombergNEF's Tier 1 list, suggesting a smaller institutional footprint than larger competitors. Vikram Solar, an Indian manufacturer, has repeatedly held Tier 1 status from BloombergNEF for at least eight consecutive quarters, giving it a clearly stronger bankability profile for financed, large-scale projects. Its nameplate capacity has grown to roughly 4.5 GW, with more recent figures citing cumulative capacity near 9.5 GW following expansions at its Falta (West Bengal) and Oragadam (Chennai) facilities - making Vikram the stronger institutional player of the two.
Resun Solar's catalog leans toward export-oriented, cost-competitive panels suited to residential rooftops and smaller commercial installations, without a strong utility-scale positioning. Vikram Solar fields a broader and more technologically current lineup, including PERC, bifacial, and newer-generation TOPCon (around 605-630 Wp) and HJT (around 710-735 Wp) modules, which lets it serve residential rooftop, commercial and utility-scale ground-mount segments alike.
For a typical buyer needing bank-financed or institutionally backed procurement, Vikram Solar is the safer default choice thanks to its confirmed Tier 1 status and more advanced cell technology mix. Resun Solar can be a reasonable option where price is the priority and bankability requirements are looser, but the two brands are not fully interchangeable given the gap in scale, technology maturity, and recognition among project financiers.
