Smart Insights (data-driven)
  • At 21.5% efficiency, this panel is on par with typical TOPCon 400-450W modules
  • Power density of 215.1 W/m² is 5.1 W/m² below TOPCon 400-450W median (220.2 W/m²) - needs more roof space
  • Temperature coefficient of -0.29%/°C matches the TOPCon 400-450W median
  • Weight of 24.0 kg is 2.2 kg above TOPCon 400-450W median (21.8 kg) - verify structural support
  • 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces

Show series description

The Solar N Plus SP-N16/108HG series is designed for maximum energy yield in situations where every square meter of roof space counts. These modules utilize N-type cells in TOPCon technology, which help minimize losses under real-world operating conditions, especially at higher temperatures and under variable sunlight. In practice, this translates to more predictable energy production and a better return on investment over the course of a year.

The use of a double-glass construction enhances resistance to microcracks and material fatigue, which is important for installations exposed to wind, snow, and frequent thermal cycling. Another key feature is bifaciality – the module can also utilize reflected light from the ground, increasing energy yield in ground-mounted installations, on bright roofs, and on carport structures.

This is a good choice for prosumers and companies that want reduced degradation over time and stable module performance over the long term, without compromising on quality.
