Written summary
Goldi Solar is an Indian module manufacturer headquartered in Surat, founded in 2011 by Ishver Dholakiya. It has been recognized as a bankable Tier 1 manufacturer by Bloomberg New Energy Finance and has expanded rapidly in recent years, growing annual production capacity from roughly 3 GW to over 15 GW, making it currently India's largest solar module producer. Hanersun is a Chinese manufacturer based in Nanjing, founded in 2015, also on BNEF's Tier 1 list, with annual production capacity around 5 GW and cumulative shipments exceeding 16 GW by the end of 2025, serving over 100 countries through branches in the US, Europe, Japan and Australia. In terms of raw manufacturing scale Goldi Solar currently has the larger industrial footprint, while Hanersun has built a broader international sales and service presence, including a notable push into Europe.
Both brands cover a similar range: residential-friendly panels in the 380-460 W class for rooftop installations, alongside larger bifacial TOPCon modules reaching 680-715 W aimed at commercial and utility-scale ground-mount projects. Goldi Solar's portfolio still leans heavily on PERC technology, roughly three quarters of its lineup, with TOPCon expanding through newer series such as HELOC Plus. Hanersun has pushed further into TOPCon, which now makes up more than half its catalog, with select models reaching 22-24 percent efficiency and warranty terms extending up to 30 years on power output.
For a typical international buyer, the two brands sit close together as second-tier alternatives to the established European and top-tier Chinese names. Buyers prioritizing the newest TOPCon technology and longer warranty terms may lean toward Hanersun, while those weighing manufacturing scale and a longer track record of high-volume shipments may favor Goldi Solar. Given that full catalog data for both companies was not independently verified here, these distinctions should be treated as directional guidance rather than a definitive verdict.
