  • Module efficiency of 22.4% is 0.9pp below average for N-type 650-700W panels (median: 23.3%)
  • At 223.7 W/m², this panel generates 8.8 W/m² less per unit area than N-type 650-700W median (232.5 W/m²)
  • At -0.29%/°C, hot weather performance is typical for N-type 650-700W panels
  • Weight of 37.5 kg is 4.0 kg above N-type 650-700W median (33.5 kg) - verify structural support
  • 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces

Show series description

The Solarspace SS9-66HD 680-710N series is designed for installations where maximizing power output per square meter and stable performance under varying conditions are paramount. These modules utilize N-type monocrystalline cells in TOPCon technology, which allows for better long-term performance and minimizes typical degradation-related losses. The use of a dual-glass bifacial construction helps to utilize reflected light from the ground, which effectively supports energy production on flat roofs, in PV farms, and on ground-mounted structures with reflective surfaces.

In practice, this series addresses two common issues: fluctuations in power output under less-than-ideal sunlight and summer efficiency losses. This supports the favorable temperature coefficient characteristic of N-type modules. Furthermore, the robust construction and high mechanical strength make it easier to design installations in windy and snowy areas. The SS9-66HD is a choice for investors who want to extract more energy from the same area, without compromising durability.

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