Written summary
Leapton is a Chinese solar panel manufacturer based in Changshu, holding a BloombergNEF Tier 1 bankability rating despite operating on a comparatively boutique scale, with published annual production capacity around 660 MW and reported plans to expand toward a 2 GW facility. Sunpro, operated by Zhejiang Sunpro Power Technology, has secured BNEF Tier 1 status for five consecutive years and runs a larger "1+2" global manufacturing footprint, with a Chinese base in Zhejiang plus overseas plants in Poland and Indonesia, pushing annual capacity to roughly 3 GW as of 2025 with further expansion added in Indonesia that year. On institutional footprint, Sunpro is the clearer leader, combining a longer Tier 1 track record with meaningfully larger and more geographically diversified production capacity.
Product-wise, Leapton focuses on PERC and N-Type TOPCon modules spanning roughly 400 W to 720 W, targeting residential, commercial, and utility-scale rooftops, with bifacial TOPCon variants emphasized for higher energy yield and warranties extending up to 30 years. Sunpro's portfolio is broader and more technology-diverse, spanning BC, TOPCon, and HJT cell technologies across dozens of models, with average efficiencies reported around 22.8 percent and top models reaching 24.6 percent, positioning it toward premium residential and commercial applications as well as utility-scale supply given its larger manufacturing base.
For a typical buyer in 2025, Sunpro is the somewhat stronger default choice given its larger, more geographically diversified production capacity, longer consecutive Tier 1 track record, and broader technology mix spanning BC, TOPCon, and HJT. Leapton remains a credible, Tier 1-rated option, particularly for residential and commercial TOPCon installations, but its smaller production scale means buyers should weigh supply chain depth and long-term company stability more carefully. In practice the two brands are not fully interchangeable, as Sunpro currently offers a more established institutional footprint.
