25% yield advantage from the "dark" side of the module
German Solar-Fabrik AG innovates the way to harvest energy from the sun. Premium L dual power takes advantage from the front and reverse side radiation that receives the module.

At this year’s Intersolar Europe, the biggest event of the solar industry, Solar-Fabrik presents its innovative high-performance Premium L dual power modules. 60 monocrystalline 6-inch cells generate electrical energy on both the front and reverse sides of the module. As a result, Premium L dual power modules increase yield by up to 25% with the same module surface area and generates higher return.
“The new Premium L dual power module allows us to achieve our promise of Premium quality in an innovative and impressive manner,” explains Guenter Weinberger, Solar-Fabrik AG’s CEO. “We make extremely efficient use of both the core material silicon and the natural resource of sunlight. The front side of the transparent module faces the sun, whereas the reverse side uses diffuse radiation and reflected light from the background. The revolutionary double-sided bifacial cells, combined with Solar-Fabrik’s technological expertise and many years of experience, are the key behind the new module type.”
Up to 25% greater yield with same surface area
Solar installations with Premium L dual power modules generate approximately 15– 25% more power compared with conventional installations. A sufficiently large distance from the ground, the inclination of the modules and, more importantly, the brightness and reflective power of the background surface (albedo) are crucial for this.
Background |
Albedo** | Increased yield |
Open terrain/ Field/Grassland | 25% | Approx. 10% |
Grey concrete | 50% | Approx. 15% |
Bright film | 78% | Approx. 25% |
Fresh snow | 90% | Approx. 30% |
Premium L dual power modules are made of 60 monocrystalline 6-inch cells and are available in three power ratings: 240, 245 and 250 Watts (W). Up to 300 W of effective output can be achieved with a rated capacity of 240 W, and up to 313 W with a rated capacity of 250 W. Vertically installed installations, e.g. on noiseinsulating walls or building façades, generate 40–50% more power. The performance ratio (PR)* – approx. 82% in conventional installations – can reach over 100% in a Premium L dual power installation.
Higher return on investment
The 15–25% higher energy yields make a solar installation with Premium L dual power modules especially profitable. The substructure and assembly cost no more than for conventional installations. Measured against the higher yield, this reduces the overall investment cost, which in turn shortens the payback period and increases return on investment.
New installation possibilities
The same mounting technology can be used to install the Premium L dual power modules as is used in conventional installations. The new module opens up a diverse range of new installation possibilities and its double-sided power generation makes it ideally suited for:
• Flat roofs • Open terrain • Shaded areas • Carports and canopies • Railings or noise-insulating walls • Façades / cold façades • Greenhouses • Pavilions
