Copper is a good conductor of electricity and can handle the high currents that solar panels produce. When it comes to wiring for solar, there are two main types of wire that can be used: stranded or solid. Both have their own advantages and disadvantages, so it’s important to know which one is right for your needs.
Solar wires (or cables) are electrical conductors that connect the photovoltaic cells within the solar panels to the rest of the solar power system. They carry the direct current generated by solar panels to the inverter or battery in the power station.
Solar panel wires and cables help you extend the connection between solar panels and power stations. This Jackery guide will help you understand the pros and cons of each type, so you can pick the one that meets your needs.
Based on the type of material, the solar panel wires are categorized into copper and aluminum wires. The copper wire carries more current than aluminum, as it has better conductivity, flexibility, and heat resistance. That said, a thin copper wire can carry more current than an aluminum wire of the same size.
Solar panels must be installed using specially designed wires to withstand harsh environmental conditions on rooftops and different installation sites. PV wires are specially designed for this purpose, making them the typical choice for PV installations. These cables even have the unique ability to withstand extremely high voltages of up to 2,000V.
An electrical cable’s conductor can be made of copper or aluminium. Copper has 60% more electrical conductivity than aluminium, which is essential to consider when choosing a solar cable. The tinned copper coating allows compliance with European standards for solar installation.
