High-Output Flexible Solar Without the Weight of Traditional Glass Panels

The Sunman eArc 320W delivers serious solar performance in a lightweight, flexible package designed for caravans, motorhomes, commercial vehicles, marine applications and off-grid power systems.

Unlike traditional solar panels that rely on heavy glass and aluminium frames, the eArc range uses an advanced composite construction that dramatically reduces weight while maintaining excellent durability and long-term reliability. The result is a high-output solar panel that is easier to handle, easier to install and better suited to applications where roof loading matters.

Built using high-efficiency monocrystalline PERC solar cells, the eArc 320W provides reliable energy production while maintaining the low-profile design that has made Sunman one of the most recognised names in lightweight solar technology.

Why Choose Sunman eArc?

For many caravan and touring setups, available roof space isn't the only limitation — weight often becomes the deciding factor.

Traditional framed solar panels can quickly add significant weight to a roof or rack system. The Sunman eArc range was designed to overcome this challenge by providing excellent solar output without the weight penalty associated with conventional glass panels.

Using a patented composite structure often compared to aircraft window technology, Sunman panels deliver exceptional strength and weather resistance while remaining remarkably lightweight.

Ideal for Touring and Off-Grid Applications

The eArc 320W is a popular choice for caravan owners, motorhome builds, commercial vehicles and off-grid installations looking to maximise solar generation without overloading roof structures.

Its combination of strong output and lightweight construction makes it particularly well suited to:

• Caravans and motorhomes

• Camper trailers

• Marine and boating applications

• Commercial service vehicles

• Tiny homes and off-grid cabins

• Remote power systems

Whether you're maintaining battery charge while travelling or building a larger off-grid energy system, the eArc 320W provides a practical balance between power output, installation flexibility and weight savings.

Flexible Mounting Options

The Sunman eArc 320W can be installed using a variety of mounting methods depending on the application and surface type.

Available mounting options include high-bond double-sided adhesive tape for low-profile installations, Structural Silicone (Fix8) for permanent mounting applications, and optional eyelets for installations requiring mechanical fastening with bolts or screws.

Always follow the recommended mounting guidelines to ensure adequate support and long-term durability.

Proven Technology Backed by Industry Recognition

Sunman technology has received support and recognition from organisations including the Clean Energy Finance Corporation (CEFC) and the Australian Renewable Energy Agency (ARENA).

The eArc range is also approved by the Clean Energy Council (CEC) for residential and commercial installations within Australia, providing confidence for both installers and end users.
