An 18 Watt solar panel for that week long caravan holiday

This solar panel uses a high efficiency crystalline cell for "all weather " charging. It is water resistant, has a robust construction for outdoor use and a 20 year cell warranty and 10 year module warranty. The 18 Watt solar panel is supplied with all the necessary cable (5m), connectors and detailed installation instructions 

What else do you need?

The 4Ah (STS01204) Charge controller should be used with this kit to protect the battery from being overcharged and to prevent reverse current drain. If you do not have one, it can be bought here.

A solar panel carry bag is available. This is a great addition where your panel will be used in temporary locations - e.g. when used with a touring caravan. Made from hard wearing shower resistant Cordura, the carry bag offers tough custom built protection for your solar panel.

A universal stand is also available. It quickly and easily fits to the panels enabling them to be used "Œfree standing " , angled to suit the time of day/year and conditions.
