This high efficiency, waterproof 275W polycrystalline solar panel with German solar cells is perfect for all off-grid installations on caravans, campervans, motorhomes and boats for charging leisure battery banks or for standalone off-grid household solar systems with batteries. It can also be used for off-grid lighting applications and for back up power systems with batteries and inverters.

The solar cells used in this panel are manufactured in Germany to the highest European quality and performance standards.

This solar panel features thick 4.0mm tempered solar glass, which makes it a lot stronger and more durable than other standard solar panels with 3.2mm glass. The robust waterproof design and strong aluminium frame of the solar panel are suitable for all weather conditions, including inland, marine applications and countries with hot or cold climates.

The panel is fitted with 2 x 0.9m of cable specially designed for solar panels to carry high currents with negligible power loss. The cable comes with waterproof MC4 connectors which can be used for easy connectivity to your existing system, for linking several panels together or for connecting 4.0mm extension cable.

Please note that this solar panel requires a 20A solar charge controller for charging batteries:
