Tier-1 warranties
Every panel carries a 12-year workmanship and 30-year linear power promise—reinforced by PID-resistant cell design in TÜV reports.
Field-tested gains
Case studies log up to 10% higher kWh/kWp versus legacy mono arrays thanks to TOPCon technology and half-cut shading tolerance.
Case study (Texas, 2025): EPC LoneStar PV swapped 450 kW of ageing poly panels for LESSO 430 W bifacials. First-quarter yield jumped 12%, trimming BOS costs $0.016/W and accelerating payback by nine months.
108 half-cut cells reach 22.02% efficiency. Stellar low-light response is documented in the official datasheet. Perfect for residential rooftops where space and curb appeal matter. See pallet pricing on the LESSO 430 W panel page.
144 half-cut 182 mm cells in a multi-busbar layout deliver up to 21.3% efficiency with solid shade resilience. Ideal for ground-mount or commercial rooftops targeting <$0.30/W hardware costs.
Prototype showcased at RE 2024 promises 23% front-side efficiency; full production awaits UL listing once the Indonesian gigafactory scales.
