This package includes 2 x 40W high efficiency, waterproof monocrystalline solar panels, each with 5m cable and MC4 connectors.

This 80W system 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).

Each 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, extension leads or to your existing system (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 provide years and years of consistent, free power. The waterproof design ensures that the panels can be used in all weather conditions.

These panels also feature 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 these solar panels for charging a 12V battery or battery bank: please note these panels require a solar charge controller / regulator to charge a 12V battery. We recommend purchasing our 10A Photonic Universe solar charge controller for these solar panels. If you are planning to add more solar panels in the future, you will require a more powerful controller; in this case, we would recommend our 20A Photonic Universe solar charge controller instead. Alternatively please visit the Solar Charge Controllers category of our online shop to view the full available range.

For installation advice please click on the Installation tab.

These 2 x 40W solar panels can be wired in parallel ("+" to "+", "-" to "-") to charge a 12V battery or battery bank, or in series ("+" of one panel to "-" of the other panel, and the other "+" and "-" to the solar controller) to charge a 24V battery or battery bank.  

These solar panels are not supplied with an installation manual as they need to be connected to further devices such as a solar charge controller or inverter which are supplied with a manual.

If you are planning to use these panels 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.
