Tax included. Shipping calculated at checkout.

Our twin core 4mm2 cable is double-insulated and uses tinned copper. The corrosion resistance of tinned copper compared to bare copper also makes this solar cable suitable for marine environments.
The outside layer of the solar cable insulation is UV treated to help protect against UV degradation.

Doing a voltage drop calculation will help to determine the correct electrical cable size required. This calculation will tell you how much energy will be lost through the electrical cable based on the thickness (cross section) and the length of the cable run. It is important to keep the voltage drop as low as possible to minimize losses.
Solar cable is sold per metre.
