With a Vmp of 19.5V, the panel is well suited to compatible 12V solar charging systems using an appropriate solar regulator.

🪶 Approx. 3.3kg
Considerably lighter than many conventional framed glass solar panels, making it attractive for caravans, motorhomes and other weight-conscious applications.

📏 Only 2mm Thick
The ultra-low-profile construction helps minimise overall installation height.

🔋 Mono-PERC Solar Cells
Uses high-efficiency monocrystalline PERC cell technology for effective energy production from a compact panel area.

↪️ Flexible Construction
The eArc construction allows installation across suitable surfaces where a conventional rigid framed solar panel may not be practical.

🔌 Under-Mounted Junction Box
The junction box is positioned underneath the panel for installations where hidden or underside cable routing is preferred.

💧 IP68 Junction Box
The supplied specifications list the junction box as IP68 rated.

🏕️ Designed for Mobile Applications

🚐 IDEAL FOR CARAVANS, MOTORHOMES & MOBILE SOLAR

The low weight and exceptionally thin profile make the Sunman eArc particularly useful where roof loading and installation height need to be kept to a minimum.

Suitable applications can include:

• Caravans
• Motorhomes & RVs
• Camper trailers
• 4WD & touring vehicles
• Yachts & marine applications
• Buses
• Trains
• Suitable fixed solar installations

🔌 SOLAR REGULATOR COMPATIBILITY

With a maximum power voltage of 19.5V and open-circuit voltage of 23.9V, the panel can be used with a suitable solar charge controller designed for the connected battery system.

For 12V battery charging, an appropriately specified MPPT or PWM solar controller should be selected according to the battery chemistry, charging requirements and complete solar-array configuration.

---

🔩 OPTIONAL MOUNTING SOLUTIONS

Several mounting methods are available depending on the surface and installation requirements.

🌬️ Vented Gap Kit
Creates an air gap beneath the panel to assist ventilation and reduce heat transfer into the mounting surface. The supplied information states an approximate installation height increase of 15mm.

📏 High-Bond Double-Sided Adhesive Tape
Provides a low-profile mounting option on appropriate smooth surfaces. Supplied dimensions are approximately 2.3mm H × 12mm W × 16.5m L.

🛠️ Structural Silicone – Fix8
Can be used as an adhesive mounting method where appropriate and where installed in accordance with the manufacturer's instructions.

---

🌡️ VENTILATED MOUNTING OPTION

For applications where panel temperature and heat transfer are a concern, the optional vented mounting system creates approximately 15mm of clearance beneath the solar panel.

This allows increased airflow beneath the panel and can assist with heat management compared with a completely flush installation.

❓ QUICK FAQ

Is this panel suitable for a caravan or motorhome?

Yes. Its approximately 3.3kg weight and 2mm panel thickness make it particularly attractive for caravan, motorhome and other mobile installations where weight and overall roof height are important.

Does the panel have a junction box on top?

No. This version has the junction box positioned underneath the panel, allowing suitable installations to keep the upper surface cleaner and cable routing less exposed.

Can I use it to charge a 12V lithium battery?

Yes, when used with a compatible solar charge controller configured for the battery's required charging profile. The panel itself does not replace the solar regulator.

What is the panel voltage?

The maximum power voltage is 19.5V, with an open-circuit voltage of 23.9V.

Can it be mounted directly to a caravan roof?

Potentially, provided the roof material, surface preparation and mounting system comply with Sunman's installation instructions. Vented and bonded mounting solutions are available depending on the application.

What warranty applies to a caravan installation?

The supplied information states a 5-year product warranty for mobile applications. The 10-year product warranty applies to qualifying building installations.
