Sunman eArc 310W flexible solar panel with eyelets — compact, high‑efficiency Mono‑PERC panel

The Sunman eArc 310W flexible solar panel combines high output with a thin, lightweight build, ideal for caravans, motorhomes, boats, and other mobile or fixed installations. Using advanced Mono‑PERC monocrystalline cells, this panel delivers strong energy harvest in a slim, bendable format that’s easier to mount on curved roofs or irregular surfaces than traditional glass panels. Factory‑fitted eyelets simplify secure attachment, making it well suited to marine biminis, caravan roofs, and other applications where a rigid frame is impractical.

Key features and benefits

• Six factory‑fitted eyelets for fast, reliable mounting.

• Lightweight, durable composite construction for long‑term use without heavy framing.

• High‑efficiency monocrystalline cells for optimal energy production in a compact package.

• Flexible design to fit curved or uneven surfaces, expanding installation options on vehicles, vessels, or temporary structures.

• Recognised by Australian clean energy bodies and CEC‑approved for residential and commercial use, supporting compliant installs.

• Warranty support: 10‑year product warranty for building installations, 5 years for mobile applications, giving buyers clearer long‑term protection.

• Cosmetic note: subtle swirl lines may appear on the surface due to manufacturing rollers; this is normal across eArc panels and does not affect performance.

Durability and materials
Sunman uses a patent‑pending composite similar to aircraft window materials, enabling high strength without glass. This reduces weight and fragility but keeps panels tough enough for real‑world use on vehicles or structures. The panels have Clean Energy Council approval for residential use, underscoring their suitability for permanent, compliant installations.

Mounting options
Installers can choose from several proven attachment methods to match the surface and environment:

• Screw or bolt through the eyelets to a continuous solid surface for a mechanically secure mount.

• High‑bond double‑sided adhesive tape for smooth surfaces when a low‑profile, clean install is preferred.

• Structural silicone such as Fix8 for strong adhesion on appropriate substrates.
  Choosing the right mounting avoids panel movement, maintains output efficiency, and reduces risk of damage in wind or vibration.

System compatibility and voltage guidance
Designed for use on both 12V and 24V battery systems when paired with suitable charge controllers:

• For 12V systems, best results occur with an MPPT solar charge controller to maximise charging efficiency and energy harvest.

• For 24V systems, MPPT or PWM controllers can be used effectively, provided the controller is sized correctly for the panel’s output.

• Important: verify the charge controller’s voltage limit against the panel’s open‑circuit voltage (Voc) before installation to ensure safe, efficient operation.

Quality control and batch consistency
There can be slight manufacturing variations between batches. When adding to an existing array, confirm compatibility with the sales or technical team to minimise mismatch issues and ensure the new panel aligns with the performance and appearance of the existing setup.

Who should choose this panel
Owners of caravans, camper trailers, motorhomes, boats, buses, or other vehicles who want a high‑output panel that is easier to mount on complex surfaces than rigid framed options. Also useful for semi‑permanent installations on curved roofs or temporary structures where weight, flexibility, and ease of mounting matter as much as efficiency.
