WATTSTUNDE® WS190SPS DAYLIGHT Sunpower Solar Panel 190 Wp

SunPower Back-Contact High-Performance Module 190 Wp - High-Power Solar Cell Meets Back-Contact Process

The WATTSTUNDE® SPS modules are significantly smaller and lighter than conventional 190 watt modules and offer a high efficiency of over 24% thanks to back-contact technology. They are therefore ideally suited for mobile use in motorhomes, garden sheds and all other 12 V solar island systems that require maximum power on the smallest possible area.

The WATTSTUNDE® SP solar modules are equipped with back-contact SunPower cells, which have a significantly higher cell efficiency than normal monocrystalline or polycrystalline solar modules, thus ensuring higher energy yield and saving volume and weight!

The modules are enclosed in a sturdy hollow chamber profile frame and promise maximum stability, even under extreme conditions.
Thanks to their anti-reflective glass, the modules let significantly more light through and therefore provide higher transmission compared to other modules. The efficiency of the monocrystalline SunPower solar modules is 24%. The modules are factory-equipped with a cable connection and MC4 connectors to simplify the connection of multiple modules.
 

Through back-contact technology, the cell can absorb more light and convert the increased absorption into electrical energy.

In normal polycrystalline or monocrystalline modules, you can clearly see the running, usually silver contacts (cell connectors) on the surface of the cell. These contacts are not present in the back-contact modules and thus prevent shading of the cell and accordingly contribute to a higher efficiency.
Thanks to the integrated bypass diodes in the junction box, the module can continue to produce electricity even in the event of shading or weak light conditions.

The solar modules of the WATTSTUNDE® WS-SP series are high-quality modules with monocrystalline SunPower cells, which always promise a top result and high energy yield. They can be installed and used in all autonomous battery applications such as motorhomes, garden sheds, camping, island systems and all OffGrid systems.

Further information
In addition to a 12 V battery, you also need a charge controller, which prevents the power supply and thus overcharging or, if necessary, deep discharge of the battery. In addition, it ensures optimal charging voltage and provides the necessary reverse current protection at night.
Please visit our category for charge controllers for this.
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 possibilities.
Please take a look at our category mounting systems for this.
Of course, we have already put together complete solar sets for various requirements. These sets include not only the modules and brackets, but also all materials necessary for installation such as connection cables, adhesive, sealant and roof penetrations.
Further information can be found in the category Solar Complete Set.
