This high efficiency, waterproof 50W 12V monocrystalline solar panel is perfect for permanent outdoor use to provide free electricity for charging 12V batteries to power various applications such as in a camper van, motorhome, boat, shed, farm, as well as remote applications such as telecommunications or monitoring equipment. It can also be used to provide a direct power supply for applications not sensitive to changes in input voltage / current (e.g. electric motors or pumps).

The panel is fitted with 5m of special solar cable which can work at high roof temperatures, with minimum power losses. A pair of male / female MC4 connectors are crimped on the end of cable for easy connection to other solar panels, your existing system or 2.5mm extension cable. The MC4 connectors can also be cut off when wiring to the screw terminals of a solar charge controller.

The long-lasting, high-efficiency monocrystalline solar cells and the tough, sealed, aluminium frame will give you years and years of consistent, free power. The waterproof design ensures that the panel can be used in all weather conditions.

This panel also features innovative 5 busbar solar cells, which are more efficient than the 2, 3 or 4 busbar solar cells used in most other solar panels, and are able to extract more power from the same surface area. This results in a smaller overall solar panel, which is ideal for applications where space is limited. These solar cells are also the best choice for applications in warmer climates, as they operate well even in high ambient temperatures.

If you are planning to use this solar panel to charge a 12V battery or battery bank: please note this panel requires a solar charge controller / regulator to charge a 12V battery.
