Monocrystalline cell technology for reliable energy generation

The solar panel uses monocrystalline solar cells, which are characterized by high efficiency in a small area. This makes the module particularly suitable for applications with limited space, such as on vehicle roofs or smaller mounting systems. With a generator output of 20 W and a module voltage of 20 V, the module can be used in conjunction with a suitable solar charge controller to charge 12V battery systems. Typical applications include small off-grid systems, lighting systems, surveillance equipment, or powering recreational vehicles.

Less Power Loss During Partial Shading

The module features an integrated bypass diode. This reduces power loss when individual cell areas are partially shaded—for example, by branches, antennas, or other objects. As a result, the solar panel can deliver the highest possible energy yield even under changing light conditions.

Robust Construction for Long-Term Outdoor Use

The frame is made of anodized aluminum, offering a sturdy construction while remaining lightweight. The front is protected by specially tempered ESG solar glass, which is designed for long-term outdoor use. With its compact dimensions of 420 x 360 x 25 mm, the module can be integrated even into smaller mounting areas. Its light weight of just 1.8 kg makes transport and installation easy. The back features a junction box with two cable entries and four mounting holes for installation.
