Smart Insights (data-driven)
  • Efficiency of 20.7% matches the PERC 400-450W median
  • At 207.4 W/m² power density, roof space requirements are typical for PERC 400-450W panels
  • Temperature coefficient of -0.34%/°C matches the PERC 400-450W median
  • At 24.0 kg (2.2 kg above PERC 400-450W median of 21.8 kg), requires checking roof load capacity
  • 70% bifaciality enables rear-side power generation, boosting yield by 4-10% on reflective surfaces

Show series description

The Seraphim Seco 400-415W series is a module series based on monocrystalline cells with PERC technology, designed to operate reliably in real rooftop conditions – even with partial shading and high temperatures. The use of a 108-cell configuration improves performance when partially shaded and reduces losses due to uneven sunlight exposure, which is a common challenge in Polish installations. The series also features a positive power tolerance, which makes it easier to maintain predictable yields throughout the entire module chain. The Seco series stands out with a watertight junction box with IP68 protection and a anti-reflective glass coating, which translates to durability and improved performance in diffused light. It is a good choice for residential and commercial installations, where reliability, weather resistance, and long-term investment returns are important.

Panels from the same series differ mainly in power output while having identical dimensions. Learn why →
