This high-efficiency, waterproof 320W monocrystalline solar panel is designed for permanent outdoor use to provide free electricity for charging 12V batteries, perfect for powering various applications such as camper vans, motorhomes, boats, sheds, farms, as well as remote applications like telecommunications or monitoring equipment. It can also be used to provide a direct power supply for applications not sensitive to changes in input voltage or current, such as electric motors or pumps. The panel comes with 5m of special solar cable that can work at high roof temperatures with minimum power losses. Additionally, a pair of male/female MC4 connectors are crimped on the end of the cable for easy connection to other solar panels, your existing system, or a 6mm extension cable.

The MC4 connectors can be removed for wiring to the screw terminals of a solar charge controller. The panel is equipped with durable, high-efficiency monocrystalline solar cells and a tough, sealed aluminum frame, ensuring years of consistent, free power. Its waterproof design allows for use 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 panels, enabling them to extract more power from the same surface area. As a result, this panel is smaller overall, making it ideal for limited-space applications. Additionally, these solar cells are the best choice for use in warmer climates, as they operate well even in high ambient temperatures. If you plan to use this solar panel to charge a 12V battery or battery bank, please note that it requires a solar charge controller/regulator.
