DOKIO 100W 18V Flexible Solar Panel for 12V Systems, ETFE Coating, MC4 Connectors — Slim, Bendable 30°

DOKIO 100W 18V Flexible Solar Panel is a thin, lightweight ETFE-coated module designed to add portable 12V power to vans, boats, campers and other curved surfaces.

This flexible solar panel combines an ultra-slim profile and ETFE top layer to maximize light transmission while staying light enough for travel and mobile installations. It outputs roughly 100 watts at 18 volts nominal and uses industry-standard MC4 connectors for easy expansion into larger 12V or 24V arrays when paired with the correct charge controller. Built for seasonal and mobile use rather than permanent rooftop replacement, the panel balances portability, bendability and durable surface protection.

How does the panel perform on curved roofs and boats?

The DOKIO panel bends safely up to a 30° arc so it conforms to many curved surfaces like van roofs, boat cabins and some trailer curves. Bending increases installation options but should be done gently and within limits to avoid damaging cells or connections.

• Safe bend radius: up to 30° arc for curved surfaces.
• Pre-drilled grommets for secure fastening with screws or straps.
• Use edge support and outdoor adhesive or VHB tape on moving vehicles.

What are the key installation and safety considerations?

Install with ventilation beneath the panel to allow heat to escape and avoid mounting directly on combustible materials. Leave cable runs visible and avoid trapping wires underneath the panel; always use an appropriate PWM or MPPT controller to manage charging for a 12V system.

• Do not mount on wood, asphalt shingles, fabric or foam without barrier and ventilation.
• Keep a gap for airflow and avoid full enclosure to prevent overheating.
• Pair with a proper controller and respect the 100W continuous rating.

How can I expand this panel into a larger power system?

MC4 connectors make it straightforward to wire multiple panels in series for higher voltage or in parallel for higher current. Proper system design requires matching panel specs, appropriate cabling, and a compatible charge controller and battery bank to ensure safe, reliable performance.

• Use series wiring for 24V systems or parallel wiring for increased amperage at 12V.
• Install bypass diodes are built-in to reduce loss from partial shading.
• Always size the charge controller and wires for combined panel output.

What maintenance and durability features should I expect?

The ETFE top layer offers improved light transmission and abrasion resistance compared with PET surfaces, and the panel is splash-resistant for outdoor use. Keep the surface clean and avoid submerging the module; treat the panel as a portable or seasonal asset rather than a permanent rooftop replacement.

• ETFE surface resists wear and improves solar capture efficiency.
• Lightweight construction (around 2.3 lb) for easy transport and mounting.
• If transit damage occurs, DOKIO support typically resolves issues quickly, often without returns.

Who is this for: This panel suits vanlifers, boat owners, weekend campers and anyone needing lightweight, bendable solar for 12V systems who values portability and easy array expansion. It’s ideal for temporary or seasonal installations and for building a modular off-grid setup when paired with an appropriate controller and battery—less appropriate as a permanent roof-first solution.
