It appears on Bloomberg New Energy Finance's bankable Tier 1 list and is currently India's largest solar PV module producer, with annual manufacturing capacity of roughly 15.2 GW and further expansion plans targeting FY2028. Resun Solar is a Chinese manufacturer based in Changzhou, Jiangsu, operating for about two decades, with annual capacity variously reported between roughly 1 and 5 GW and a sales network spanning 20 to 80 countries depending on the source, but it does not currently appear on published BNEF Tier 1 lists. On institutional footprint and verified production scale, Goldi Solar holds the stronger position. Both brands serve residential rooftop, commercial and utility-scale segments. Goldi Solar runs a broader technology mix, still producing PERC modules alongside a newer bifacial TOPCon line (such as the HELOC Plus G12 series, up to 705 W with efficiency around 22.7 percent), giving buyers a choice between cost-driven legacy technology and higher-output modules. Resun Solar has moved almost entirely to TOPCon cells, offering panels from roughly 420 to 590 W with average efficiency near 22.3 percent, making its catalog narrower but technologically consistent. For a buyer prioritizing verified bankability and manufacturing scale, particularly on bank-financed projects, Goldi Solar is the safer default. Resun Solar remains a reasonable option where a focused, competitively priced TOPCon lineup is the main requirement, though the absence of a current Tier 1 listing may limit its eligibility for certain institutional tenders.
