semi-flexible solar panel 110Wp "black tiger sf 110" (ETFE surface, 31x Sunpower cells, 1080x540mm)

Semiflexible solar module for curved surfaces

Our semi-flexible solar modules are ultra-flat and particularly suitable for slightly curved surfaces. They can be installed directly on the roof of the camper without a compensating substructure. With their extra high efficiency of over 24%, an improved temperature coefficient and other features, they are designed for maximum performance for more electrical power per area for your camper.

Cell efficiency

It's worth comparing! This frameless, semi-flexible solar module is uncompromisingly designed for maximum energy yield per area and offers a full 24.2% efficiency! This is possible through the exclusive use of top of the range Sunpower cells.

What does that mean: Solar cells are not 100% the same. Therefore, immediately after their production, they are bombarded with light under very specific conditions, their performance is assessed and classified into certain quality levels according to the results. For the production of all our solar modules, we only use cells that have achieved the highest rating.

24.2% efficiency is the highest level of current technology and with an improved temperature coefficient and microlenses on the surface, we get this in the best possible way, for example, even in high heat or in an inclined sun.
 

Optimized temperature coefficient

With increasing heat, the performance of solar modules decreases. Many conventional modules have a problem here, especially with direct installation on the roof surface and thus poor ventilation.

For this reason, we have optimized our solar modules for a better temperature coefficient (power loss per degree Celsius). At high temperatures, they achieve an energy yield that is up to 25% higher than most conventional modules!

ETFE surface with microlenses

ETFE has similar features to Teflon coating on domestic frying pans. Due to the dirt-repellent "anti-stick" surface, the semi-flexible solar module stays clean longer and therefore efficient until the next cleaning. This is particularly easy thanks to the ETFE surface. ETFE is also more translucent than other plastics.

The surface of "black tiger sf" is equipped with microlenses. In this way, the reflection of the light, when the sun is at an angle, is reduced and the light waves are captured much better. They are bundled and directed onto the cell surface.
 

Highest reliability

The extremely thin cells of the semi-flexible solar module not only make it less susceptible to mechanical damage.
"black tiger sf" also has a full-surface copper contact layer on the back. On the one hand, this ensures that the surface on the front is less concealed, and on the other hand, it also ensures that the module continues to function if microcracks have occurred due to external influences. In the conventional way of making contact, however, if individual cells or cell areas are damaged, the entire solar module often is affected.
 

Flexibility

The frameless "black tiger sf" solar modules in 110 and 160 Wp are flexible enough to adapt to the curvature of your vehicle's roof. There is no need to create a level substructure or a roof rack.

Flexibility of this module with 110 Wp over the length: 4.2%. This means that the outer edges of the long side may be bent downwards by 45 mm, starting from the middle of the module (see our small sketch in the assembly instructions / adhesive instructions for illustration. You can find this here in the article under "PDF".)

Please note: The modules may only be bent lengthways.
 

Ultra flat and ultra light

This ultra-light module weighs just 3.5 kg. A laminated fiberglass plate ensures stability despite its low weight.
connection

The connection is made on the front using a pre-assembled, 7 m long cable with a diameter of 2 x 4mm2 in a waterproof junction box. For roof penetration we recommend the $ # a: 124542: waterproof cable penetrations from Scanstrut (6-10mm) # $.
 

Solar controller

A solar controller is always required to connect the panel to the battery. To connect the panel to a solar controller, the cable only needs to be laid in the vehicle and connected to the corresponding "+" and "-" poles of the controller.
The $ # a: 124827: SmartSolar MPPT 75/10 # $ solar controller is sufficient for one module. If you want to connect several panels together, a larger controller is required. You can find out which controller you need with the following calculation:
The values ??of an MPPT 75/10 mean a maximum of 75V open circuit voltage of the panel (Voc) and a maximum of 10A nominal charging current. The Voc value is in the data sheet for each panel, the nominal charging current must be calculated. The black tiger sf 110 has a voc of 40.80V. That is less than 75V and therefore the solar regulator is empty with 75V
