This high-efficiency, waterproof 250W monocrystalline solar panel is designed for permanent outdoor use. It provides free electricity for charging 12V batteries to power various applications, such as in a camper van, motorhome, boat, shed, farm, and 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/current, such as electric motors or pumps. The panel comes with 5m of special solar cable, capable of working at high roof temperatures with minimum power losses. It is fitted with a pair of male/female MC4 connectors crimped on the end of the cable for easy connection to other solar panels, an existing system, or 6mm extension cable. The MC4 connectors can also be removed for wiring to the screw terminals of a solar charge controller. The long-lasting, high-efficiency monocrystalline solar cells and the tough, sealed aluminum frame ensure consistent, free power for years. The waterproof design allows the panel to be used in all weather conditions. This panel also features innovative 5 busbar solar cells, which are more efficient than the typical 2, 3, or 4 busbar solar cells used in most other solar panels, and can extract more power from the same surface area. This results in a smaller overall solar panel, ideal for applications with limited space. These solar cells are also the best choice for applications in warmer climates, as they operate well even in high ambient temperatures.

If you plan to use this 250W solar panel to charge a 12V battery or battery bank, please note that you will need a solar charge controller or regulator. You can find a variety of solar charge controllers in the Solar Charge Controllers section of our online shop.

This product comes with a 1-year workmanship warranty provided by Photonic Universe. They will repair or replace defective items at their discretion. Additionally, the solar cells are guaranteed to produce at least 90% of nominal power 10 years after purchase and at least 80% of nominal power 25 years after purchase. This warranty is provided by the manufacturer of the solar cells.

Please note that this solar panel does not include an installation manual, as it needs to be connected to additional devices such as a solar charge controller or inverter, which are supplied with their own manual. If you intend to use this panel to charge a 12V battery, we recommend purchasing one of our solar charge controllers. All of our solar charge controllers include an instruction manual with detailed installation instructions and wiring diagrams. If you need help with installation or have any technical questions, we can provide free support - please contact us via email or phone.
