620W N-Type Bifacial Solar Panel 132 Cells

The 620W N-Type Bifacial Solar Panel 132 Cells is a next-generation high-efficiency photovoltaic module designed for commercial, utility-scale, rooftop, and PV plant applications. Featuring advanced N-type half-cell technology with 132 cells arranged in a 6×22 configuration, the 620W N-Type Bifacial Solar Panel 132 Cells captures sunlight from both front and rear sides, delivering up to 684Wp under bifacial enhancement conditions. With a maximum rated power of 620W+ and module efficiency reaching 23.0%, the 620W N-Type Bifacial Solar Panel 132 Cells achieves industry-leading performance with just 1% first-year degradation and 0.4% annual degradation, retaining 87.4% power output after 30 years.

 Higher Power Output with 132 Half-Cells – Unlike smaller 144-cell configurations, the 620W N-Type Bifacial Solar Panel 132 Cells uses a 132-cell (6×22) layout to achieve 620W+ rated power and 23.0% module efficiency, delivering 23.0% efficiency under STC and up to 25.3% under BSTC conditions.

 Superior Bifacial Energy Gain – The 620W N-Type Bifacial Solar Panel 132 Cells generates extra energy from the backside depending on ground albedo, with maximum bifaciality of 80±5% and a bifacial gain exceeding 10%, reaching 684Wp under optimal rear-side reflection (135W/m²).

 Excellent Temperature Coefficients – With a Pmax temperature coefficient of only -0.30%/°C and NMOT of 45±2°C, the 620W N-Type Bifacial Solar Panel 132 Cells maintains high performance even in elevated operating temperatures.

 Dual-Glass Durability – Featuring 2.0mm high-transmittance anti-reflective tempered front glass and 2.0mm semi-tempered rear glass, the 620W N-Type Bifacial Solar Panel 132 Cells provides superior protection against micro-cracks, PID, and environmental stress.

 Three Power Tiers for Design Flexibility – Available in 610W, 615W, and 620W variants, the 620W N-Type Bifacial Solar Panel 132 Cells offers electrical characteristics including Voc from 47.90–48.30V and Isc from 15.85–15.95A, enabling optimized system design.

 Low Degradation for 30-Year Performance – The 620W N-Type Bifacial Solar Panel 132 Cells features linear power output warranty with 1% first-year degradation and 0.4% annual degradation, guaranteeing 89.40% power at year 25 and 87.40% at year 30.

 High System Voltage & Load Capacity – Rated for 1500V DC maximum system voltage with 30A maximum series fuse rating, the 620W N-Type Bifacial Solar Panel 132 Cells withstands wind loads of 2400Pa and snow loads of 5400Pa for diverse climate conditions.

 IP68 Junction Box with 3 Diodes – Built for reliability, the 620W N-Type Bifacial Solar Panel 132 Cells is equipped with an IP68-rated junction box that provides excellent protection against moisture and dust ingress.

 Class A Fire Rating & PFAS-Free – Safety-certified with Class A fire rating, the 620W N-Type Bifacial Solar Panel 132 Cells is also free from perfluoroalkyl and polyfluoroalkyl substances (PFAS), meeting stringent environmental standards.

 Sustainable Manufacturing – Constructed with a high percentage of recyclable materials and backed by Ecovadis certification, the 620W N-Type Bifacial Solar Panel 132 Cells represents an environmentally responsible choice.

 Comprehensive Certifications – Manufactured under ISO 9001, ISO 14001, and ISO 45001 management systems, the 620W N-Type Bifacial Solar Panel 132 Cells complies with IEC 61215 and IEC 61730 standards, backed by Baolite Group's 40+ years of manufacturing experience since 1982.
