login to saveProduct Description
This waterproof high efficiency 20W solar panel is perfect for permanent outdoor use to provide free power either directly, such as powering a fan or lights, or for charging a 12V battery to then power hundreds of devices such as in a shed, boat or camper van.
The long-lasting, high-efficiency, polycrystalline solar cells and the tough, sealed, aluminium frame will give you years and years of consistent, free power. Waterproof design ensures the panel can be used in all weather conditions.
The panel comes with 2m cable which is attached to the waterproof junction box at the back. Please note that the junction box goes about 0.5cm beyond the frame, so there must be some space left between the frame and flat surface when mounting the panel (note 1.0 - 1.5cm space under the panel typically recommended for cooling).
If you are planning to use this solar panel for charging a 12V battery: please note this panel requires a solar charge controller / regulator to charge a 12V battery. If you don't have one and would like to buy it, please check our shop category with solar charge controllers.
If you already have one of our 20W solar panels or kits with a solar controller, you can easily upgrade the power of your kit to 40W by adding this panel in parallel to the existing 20W solar panel (connecting 2 panels: "+" to "+", "-" to "-" and then to the solar controller).
