High efficiency 320W monocrystalline solar panel made using high quality German-manufactured solar cells. Designed to get the most out of low light conditions, this panel can still produce a good amount of power even when not in direct sunlight. Sealed in a tough aluminium frame with a waterproof design, this panel can be used in all weather conditions so is suitable for permanent outdoor installations. It's ideal for static applications, such as in an off-grid systems, or for use on boats and vehicles such as campervans, motorhomes, caravans and 4x4s.
This panel comes pre-fitted with two 5m lengths of solar-specific, UV-resistant cable that is designed to perform well even at high temperatures, with minimal power losses. The cables are terminated with male and female MC4-compatible solar connectors, allowing you to connect to other panels or to extension cables. Alternatively, these connectors can be cut off to enable the cable to be fitted to the screw-clamp terminals of a solar charge controller.
Rigid framed solar panels can be mounted using plastic or metal brackets which can be found in our Mounting Accessories section.
Note: This panel must be used with a suitable solar charge controller and not connected directly to a battery. No instructions are provided with this panel as it is intended to be connected to a solar charge controller which will have instructions for use.
