Middle of its segment, needs the roof space
The Solarspace SSA-54HD 485-510N (Lumina II) series are monocrystalline modules designed for high performance in real-world conditions, even under cloudy skies and at elevated temperatures. The use of N-type cells in TOPCon technology results in more stable energy production over the long term, with limited degradation and good performance even in less sunny conditions. This is a practical solution to a common problem faced by installers and investors: how to maximize energy yield from a limited roof area.
The Lumina II modules also stand out due to their favorable temperature coefficient, which helps maintain efficiency during the summer months when traditional systems lose the most performance. Additional safety is provided by their robust construction and sealed connection box, as well as compatibility with popular connectors, which makes installation and maintenance easier.
This is a good choice for residential and commercial installations, where maximizing energy yield from a limited space and predictable performance over the years are important, and these are supported by a long linear warranty.

Residential, commercial and hot-climate.
Roofs where every square metre has to count, tight roof space and weight-limited structures.
Bottom 12% of the N-type 450-500 W segment, against a median of 225.2.
Bottom 13% of the N-type 450-500 W segment, against a median of 22.52%.
Bottom 20% of the N-type 450-500 W segment, against a median of 49.5.
- Module efficiency of 21.8% is 0.7pp below average for N-type 450-500W panels (median: 22.5%)
- At 218.1 W/m², this panel generates 7.1 W/m² less per unit area than N-type 450-500W median (225.2 W/m²)
- Temperature coefficient of -0.29%/°C matches the N-type 450-500W median
- At 26.5 kg (2.8 kg above N-type 450-500W median of 23.7 kg), requires checking roof load capacity
- 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces
