Bifacial solar panel: up to 30 % more production

Thanks to its bifacial technology, the Solar Fabrik Mono S4 captures light from both sides. It can harness reflected radiation from surfaces like concrete, pebbles, or metal. Achieving an extra energy production on top of its rated 450 Wp output.

This design can boost energy production by up to 30%, depending on installation conditions. The more reflective the surface underneath and the higher the panel is mounted, the more extra output you get from the rear side.

You’ll see the biggest gains in setups like:

• Light concrete or reflective metal: up to 30%
• White wall (vertical surface): up to 25%
• Pergolas with reflected light: 10–20%
• Balconies with glass railings: up to 25%
• Concrete (standard): up to 15%
• White pebbles: 20–25%
• Grass: up to 10%

Its clean, full-black design is sleek, discreet, and visually stunning, with a high-end finish that looks great in any type of installation.
