DOKIO Flexible Solar Panels 2-Pack (2×100W, 18V) ETFE Coated — Bendable 30° for 12V Systems, MC4 Ready

The DOKIO 200W Flexible Solar Panel kit is a pair of lightweight, ETFE‑coated 100W panels that bend up to 30° to power or charge 12V systems in mobile and compact installations.

Two slim, flexible photovoltaic panels—each rated 100W at 18V—arrive ready to wire in series or parallel with MC4 connectors and a durable ETFE surface. Designed for curved surfaces like van roofs, boats, or RVs, this 2‑pack balances portability, installation options, and improved durability compared with basic polymer finishes. The kit emphasizes cooling clearance and safe mounting practices so you get reliable output from a low-profile package.

How do these panels fit into a 12V electrical system?

The pair produces a nominal 18V per panel, allowing straightforward connection options for 12V battery charging. Wire a single 18V panel to a 12V MPPT charge controller for efficient charging, or combine both panels in parallel for higher current at the same voltage. Series wiring is also possible when using an appropriate MPPT rated for the resulting voltage.

• Each panel is 18V nominal; use an MPPT or PWM charge controller for battery charging.
• Parallel: higher amperage output for faster charging of 12V banks.
• Series: increased voltage for higher-voltage controllers or long cable runs.
• Equipped with MC4 connectors for plug-and-play wiring and secure connections.

Will the flexible design hold up on curved roofs and in mobile use?

Yes. The panels are specified to flex safely up to about 30°, making them suitable for gently curved surfaces common on vans, trailers, and marine decks. The ETFE top sheet improves light transmission and resists weathering, while the slim profile reduces wind catch and simplifies low-clearance installations. Follow the manufacturer’s guidance to leave ventilation space beneath the panel to avoid heat buildup.

• Bendable up to 30° for conforming to curved roofs and rounded cabins.
• ETFE surface for better light transmission and resistance to abrasion.
• Cooler operation when mounted with ventilation; avoid direct adhesion to combustible materials.
• Lightweight construction eases carry, placement, and temporary mounting.

How should I install and maintain these panels safely?

Install with attention to airflow and secure fastenings—do not mount directly onto wood, fabric, asphalt shingles, or other combustible substrates. Leave a small gap for heat dissipation and avoid routing cables beneath the panel. For longevity, periodically inspect MC4 connectors, clear debris from the panel surface, and check mounting points after heavy travel or weather events.

• Maintain ventilation gap; do not trap heat or run cables underneath.
• Secure with adhesives or low-profile fasteners suitable for flexible panels and your roof material.
• Check MC4 connectors for tight, clean connections and replace damaged wiring promptly.
• Wipe the ETFE surface clean with mild soap and water; avoid harsh abrasives.

Who is this for? The DOKIO 200W Flexible Solar Panels 2‑pack is aimed at van lifers, weekend boaters, RV owners, and anyone needing a low-profile, portable solar solution where rigid glass modules won’t fit. It’s also useful for temporary setups, pop-up events, and DIY solar projects where lightweight, bendable panels, easy MC4 wiring, and reinforced shipping protection streamline installation and reduce transport hassle. If you want a compact, adaptable array to feed a 12V system or an MPPT controller in tight spaces, this kit offers a practical balance of output, flexibility, and weather-resistant materials.
