WATTSTUNDE® WS80SPS DAYLIGHT Sunpower Solar Panel 80 Wp

SunPower Back-Contact High-Performance Module 80 Wp - High-Power Solar Cell Meets Back-Contact Technology

The WATTSTUNDE® WS SPS series solar modules are high-quality modules with monocrystalline SunPower cells that always promise top results. They are characterized by excellent quality and performance efficiency. By using only high-quality components and innovative Back-Contact SunPower solar cells, an above-average cell efficiency of over 22% is achieved. So nothing stands in the way of your next adventure (even in wind and weather)!

Mobile yet Robust

The housing frames of all WATTSTUNDE® DAYLIGHT models are made of anodized aluminum - this light yet strong material guarantees a high degree of mobility and resistance. It is extremely weather-resistant and highly stable, making it the ideal material. With dimensions of 810 x 535 x 35 mm and a weight of only 5.45 kg, they are significantly smaller and lighter than conventional 80-watt modules.

Specially Manufactured ESG Anti-Reflective Glass

The high-performance modules are equipped with acid-etched anti-reflective glass, which has a self-cleaning effect (lotus effect). Due to a special pre-treatment, the solar modules have high transmittance, which results in increased power generation. Whether in storms, hail, snow, or saltwater - thanks to their stable construction and water-repellent surface, they withstand even extreme climatic conditions!

Stable Wind and Weatherproof Construction

Due to our personal commitment to the quality of our solar modules, we monitor every production step: from cell manufacturing to the assembly of components into the finished product. The modules thus exhibit a stability that meets the demands of outdoor use. They are therefore ideally suited for mobile use on motorhomes, in garden sheds, and all other 12V solar island systems. Easy installation, quick commissioning, and prepared materials make assembly a breeze!

Optimal Energy Yield

The WATTSTUNDE® SPS DAYLIGHT solar modules are equipped with Sunpower cells with back-contact technology. But what does that mean? With normal modules, you can clearly see the visible, usually silver-colored contacts (cell connectors) on the surface of the cell. These contacts are not present in back-contact modules, thus preventing shading of the cell. Thanks to their anti-reflective glass, the modules allow significantly more light to pass through and therefore ensure higher transmission compared to other modules. The result is a significantly higher cell efficiency of over 22%, which ensures a higher energy yield, which in turn saves volume and weight!
Optimal performance in the smallest space - especially in poor and diffuse light conditions, the high-performance modules guarantee a constant energy supply.

IP65 Protection

The modules are factory-equipped with a 90 cm cable connection and MC4 connectors to simplify the connection of multiple modules.
They can be installed and used in any self-sufficient battery applications such as in RVs, garden sheds, camping, island systems, and all off-grid systems.
Thanks to the integrated bypass diodes in the junction box, the module can continue to produce electricity even with shading or weak light conditions. The junction boxes are protected against the ingress of water and dust according to IP65.

Further Information

In addition to a 12V battery, you also need a charge controller, which prevents overcharging or, if necessary, deep discharge of the battery by regulating the power supply. In addition, it ensures optimal charging voltage and guarantees the necessary reverse current protection at night.
Please visit our category for charge controllers.
Furthermore, the question of suitable mounting for the new solar panel often arises. Here we have various brackets, mounting systems, and mounting spoilers for attachment to motorhomes, house walls, and many other options.
Please take a look at our category mounting systems.
Of course, we have already put together complete solar kits for various requirements. These kits include not only the modules and brackets but also all materials necessary for installation such as connection cables, adhesives, sealants, and roof penetrations.
Further information can be found in the category Solar complete kit.
