Seraphim Sable 620W (Pallet of 36) High Efficiency Bifacial Solar Panels SRP-620-BTC-BG

The Seraphim Sable SRP-620-BTC-BG is a 620W high-efficiency bifacial solar module built with N-type TOPCon technology and 132 half-cut cells. Designed for strong energy yield, long-term durability, and low degradation, the module combines high front-side power with bifacial rear-side energy generation for demanding solar installations.

Seraphim backs the module with a 15-year product warranty and 30-year linear power output warranty.

Key Technology

• 620W Rated Power
  Delivers 620 watts of front-side maximum power at Standard Test Conditions.

• 22.95% Module Efficiency
  High module efficiency helps maximize power production from the available array footprint.

• N-Type TOPCon Technology
  Uses advanced TOPCon solar cell architecture designed for improved energy yield, low degradation, and strong temperature performance.

• Bifacial Energy Generation
  Designed to produce additional energy from reflected irradiance reaching the rear side of the module.

• 80% ±5% Bifaciality
  High bifaciality enables substantial rear-side contribution when installed over reflective surfaces or in optimized bifacial mounting configurations.

• 132 Half-Cell Design
  Built with 132 TOPCon half-cells based on 182 × 105 mm cell dimensions.

• Multi-Busbar Technology
  Multi-busbar construction supports efficient current collection and improved module reliability.

• Low Temperature Losses
  A -0.29%/°C Pmax temperature coefficient helps maintain stronger output as module temperature increases.

• Excellent Low-Light Performance
  Designed for strong energy generation during lower irradiance conditions such as mornings, evenings, and cloudy weather.

• Reduced Hot-Spot Effect
  Cell and interconnection design helps reduce localized hot-spot risks under partial shading and uneven operating conditions.

• Dual-Glass Construction
  Uses 2.5 mm front and 2.0 mm rear semi-tempered, low-iron glass with anti-reflective coating.

• Strong Mechanical Load Capacity
  Rated for 5400 Pa front-side and 2400 Pa rear-side mechanical loading.

• 40 mm Hail Test
  Meets HW4 40 mm hail test performance requirements specified on the datasheet.

• 30-Year Linear Power Warranty
  Backed by a 30-year linear output warranty with a long-term retained-power profile reaching approximately 87.4% at year 30.

• 15-Year Product Warranty
  Includes a 15-year guarantee on product materials and workmanship.

Best Uses

• High-Power Solar Arrays
  Ideal for installations requiring high wattage per module to reduce module count and balance-of-system hardware.

• Bifacial Installations
  Well suited for ground-mounted, elevated, and reflective-surface installations where rear-side irradiance can increase energy production.

• Large Rooftop Installations
  Suitable where high module wattage and strong power density are important for maximizing installed capacity.

• Hot-Climate Solar Systems
  The low Pmax temperature coefficient helps limit output losses under elevated operating temperatures.

• High-Wind and Snow Environments
  Strong 5400/2400 Pa mechanical load capability supports installations exposed to demanding structural conditions.
