The Solarspace Lumina I SS8-54HSB 395-405M (All Black) series is a range of modules designed for installations where both aesthetics and long-term stable energy production are important. These modules feature monocrystalline mono PERC p-type cells in a half-cut configuration, which improves performance under partial shading and reduces the risk of hot spots. The design with multiple busbars (MBB) and high-density laminating supports better current collection and higher resistance to microcracks, which is especially important on roofs exposed to wind and snow loads. The All Black version provides a consistent, dark surface - a real advantage where the installation needs to be discreet and aesthetically pleasing.

These panels are suitable for single-family homes, premium investments, and on the roofs of small to medium-sized commercial buildings, where you need a compact module with high power density without compromising on durability and appearance.

Common questions

6 answered
What warranty does the Solarspace Lumina I SS8-54HSB 395–405M come with?
Solarspace provides a 25-year product warranty and a 25-year linear power warranty. Per the datasheet, the module retains at least 84.8% of its rated output at year 25. Annual degradation is capped at ≤0.55%, ensuring stable energy production throughout the full service life of the installation.
Do the Solarspace Lumina I All Black panels handle partial shading from a chimney or dormer?
Yes. The Lumina I series uses 108 half-cut PERC cells — each cell is split in two, so shading one section does not shut down the rest of the string. The multi-busbar (MBB) design further improves current collection and reduces hot spot risk, which is common under non-uniform irradiance on obstructed rooftops.
What are the dimensions and weight of the Solarspace Lumina I 405W module — will it fit on a standard pitched roof?
The module measures 1722×1134×30 mm and weighs approximately 21 kg (46 lbs). This compact footprint simplifies rooftop transport and installation on standard aluminum or steel racking systems. The size suits both smaller pitched roofs on single-family homes and larger commercial rooftops equally well.
What wind and snow loads can the Solarspace Lumina I SS8-54HSB withstand?
The panel is rated for 5,400 Pa front load, covering extreme snow and wind scenarios, and 2,400 Pa rear load. High-density lamination combined with the MBB busbar architecture reduces the risk of cell microcracks, which most often develop under repeated mechanical stress from wind and snow cycles over the module's lifetime.
What sets the All Black version of the Solarspace Lumina I apart from standard solar modules?
The All Black version features a uniformly black frame, backsheet, and cells, delivering a visually seamless appearance on the roof. This matters for premium residential projects or heritage-zone installations where aesthetics are a requirement. Core specs — up to 405 Wp output, up to 20.74% efficiency, mono PERC half-cut cells — remain unchanged from the standard version.
What types of installations are the Solarspace Lumina I SS8-54HSB 395–405M modules best suited for?
The Lumina I series targets single-family homes, premium residential projects, and small-to-medium commercial buildings. At 405 Wp per panel, a 10 kWp system requires only 25 modules. The combination of compact dimensions, all-black aesthetics, and mono PERC half-cut technology makes it a strong choice wherever high power density, durability, and visual appeal all matter.
