A 150 Watt solar panel for use on caravans or permanent fitting

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 150 Watt solar panel is supplied with all the necessary cable (5m), connectors and detailed installation instructions. The supplied cable, designed for photo voltaic uses, guarantees that each module has excellent power transmission throughout the year. In common with all the larger panels, it includes bypass diodes to minimise the effect of shadows on charging capability.

What else do you need?

The 12Ah (STSPR10) Charge controller or equivalent must 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.
