What Are Solar Cables?

A solar cable is one which comprises a number of insulated wires. They are also used to interconnect the several components in a photovoltaic system. However, a major plus point is that they are resistant to extreme weather conditions, temperature, and UV. The higher the number of conductors it contains, the greater its diameter.

• They come in 2 types – solar DC cable and solar AC cable – a direct current and alternating current variation.
• Solar DC cable is available in 3 sizes – 2mm, 4mm, and 6mm diameter. They can either be module cables or string cables.
• The same principal must be kept in mind while choosing a solar cable size – slightly larger and higher voltage than required.
• The quality of a solar cable is determined by its resistance, ductility, malleability, heat capacity, dielectric strength, and free from halogen.

KEI Solar cables are suitable for permanent outdoor long- term use, under variable and harsh climate extremely resistant to weathering, UV- radiation and abrasion conditions. Individual modules are connected using cables to form the PV generator. The modules are connected into a string which leads into the generator junction box, and a main DC cable connects the generator junction box to the inverter.

Additionally, it is salt water resistant and resistant to acids and alkaline solution. Also suitable for fixed installation as well as for moving applications without tensile load. It is especially designed for outdoor use, which means direct sun radiation and air humidity, due to the halogen free & cross- linked jacket material the cable can also be installed in dry and humid conditions indoors.

They are designed and tested to operate at a normal maximum temperature 90 deg. C. and for 20,000 hours up to 120 deg. C.
