Portable 10 W solar panel for 12 V batteries

This 10 W monocrystalline panel delivers 18 V at 0.55 A with a 17 % conversion rate. It is designed to maintain or charge 12 V lead-acid batteries in cars, boats and similar vehicles. The lightweight glass-fibre laminate weighs 254 g and measures 318 by 210 by 5 mm. It suits outdoor projects such as robotics, RC models, lighting or small fans.

Check voltage and charge controller compatibility

Verify that your battery system is nominally 12 V and that you have a suitable charge controller or regulator for an 18 V open-circuit source. The panel terminates in a power cable with crocodile clips for direct connection. Ensure the cable length reaches your mounting location and that the clips fit your battery terminals. No built-in controller or blocking diode is mentioned in the specifications.

Durable laminate with simple mounting

The glass-fibre laminated board resists weather and vibration for permanent or temporary outdoor use. At 5 mm thick it can be screwed, tied or Velcro-mounted to flat surfaces on vehicles, decks or frames. Crocodile clips allow quick attachment and removal without tools. The blue finish is purely cosmetic and does not affect output.

Questions about this item

Does the panel come with cables and clips for connecting to a 12V battery, or must I buy them separately?

The package includes the 10W panel, one power cable and one crocodile clip, so no extra leads are needed for a basic 12V connection.

Should I choose a higher-wattage panel or is the 10W 18V 550mA version sufficient for trickle-charging a 12V car or boat battery?

At 10W, 18V and 550mA this panel is designed for trickle-charging 12V batteries in cars, boats or similar applications.

What does the 17% conversion rate mean for actual charging performance in daylight?

The 17% conversion rate means roughly one-sixth of the sunlight hitting the 318mm by 210mm monocrystalline surface becomes usable 18V current for the battery.
