## Summary

Leapton is a manufacturer with Japanese corporate roots - Leapton Energy was founded in Kobe, Japan in 2012 - but all module production takes place in Changshu, Jiangsu, China, where the factory was established in 2017. The company grew rapidly, reaching approximately 3 GW of annual production capacity by late 2024, and has secured BloombergNEF Tier 1 bankability status, making it eligible for institutional project financing. LONGi Solar, headquartered in Xi'an, China, operates at an entirely different scale: the company's HPBC 2.0 cell capacity alone exceeded 46 GW, and LONGi plans to ship approximately 80 GW of modules across 2026. LONGi has maintained consistent BloombergNEF Tier 1 status and, as of early 2026, also debuted on the BNEF Tier 1 energy storage list. By any measure of institutional footprint - financing access, supply security, and R&D investment - LONGi occupies a substantially larger and more established global position.

Leapton's current portfolio centers on N-type TOPCon cell technology, with bifacial models ranging from 440 W to 585 W. The company earned a Top Performer designation in Kiwa PVEL's 2025 PV Module Reliability Scorecard, which provides independent third-party validation beyond marketing materials. Its panels target residential rooftop and commercial-and-industrial (C&I) segments primarily, and a 30-year power warranty applies to bifacial and N-type products. LONGi structures its portfolio around its proprietary HPBC 2.0 back-contact cell technology. For residential rooftop use, the Hi-MO X10 EcoLife series delivers up to 510 W at up to 25% module efficiency and received a 2025 Smarter E Award. For utility-scale ground-mounted projects, the Hi-MO 9 series reaches up to 670 W output at 24.8% efficiency, also backed by a 30-year power warranty. LONGi additionally holds world cell efficiency records, including 27.81% for its HIBC cell and 34.85% for a silicon-perovskite tandem structure.

For buyers focused on residential or mid-size commercial installations, Leapton offers a credible Tier 1-rated option with competitive N-type TOPCon technology and PVEL Top Performer validation - well suited to cost-sensitive projects that still require documented bankability. LONGi is the stronger default for buyers where supply-chain security, leading-edge cell technology, and long-term institutional confidence carry the most weight, particularly in larger C&I or utility-scale projects where panel performance data and manufacturer stability are heavily scrutinized. The two brands are not interchangeable in practice: LONGi's scale and R&D depth give it a clear technology and institutional advantage, while Leapton represents a legitimate mid-tier alternative for buyers who prioritize value without sacrificing Tier 1 credentials.
