• Electrical Cable for Solar Panels 4.6 mm²

Solar Panel WIRING

Low voltage cable with double insulation for extra protection is suitable for any low voltage DC power such as solar panel wiring.

For solar panel wiring the main consideration is the voltage drop caused by the electrical resistance of the wiring. A 12 volt solar panel wired to a 12V battery with thin WIRING!! might lose more than 1 volt due to voltage drop, so the system is losing more than 10 % of the available solar power.

How to calculate voltage drop for cable: multiply cable electrical Resistance times amps flowing through cable times twice the length of cable in meters

Formula: volts = Amps x Ohms (V= IR)
