PV Solar Cable Sizes & Types
There are two types of solar cables: AC cables and DC cables. DC cables are the most important cables because the electricity we harness from solar systems and use at home is DC electricity. Most solar systems come with DC cables that can be integrated with the adequate connectors. DC solar cables can also be purchased directly on ZW Cable. The most popular sizes for DC cables are 2.5mm, 4mm, and 6mm cables.
Depending on the size of the solar system and the electricity generated, you may need a larger or a smaller cable. The vast majority of solar systems in the US utilize a 4mm PV cable. To install these cables successfully, you have to connect the negative and positive cables from the strings in the main connector box supplied by the solar manufacturer. Virtually all DC cables are used in external locations such as the rooftop or other areas where the solar panels are laid out. To avoid accidents, positive and negative PV cables are separated.
