Solar Cable Overview

A solar cable is an electron beam cross-linked cable rated at 120°C that can withstand harsh weather conditions and the mechanical shock of the equipment to which it belongs. Solar technology will be one of the green energy technologies of the future, and solar photovoltaic (PV) is becoming more widely used internationally.

Environmental Adaptability

For photovoltaic applications, materials used outdoors should be based on UV light, ozone, drastic temperature changes, and chemical attack. Solar systems are often used in harsh environmental conditions, such as high temperatures and UV radiation. The advantage of solar cables is that they are rated for 120°C (20,000 hours of use). This rating is equivalent to 18 years of use at a continuous temperature of 90°C. And when the temperature is below 90°C, the service life is even longer.

Selection of Photovoltaic Solar Cables

The cables used in the low-voltage DC transmission part of solar photovoltaic power generation systems have different requirements for the connection of different components due to different usage environments and technical requirements. The overall factors to be considered are the insulation performance of the cable, heat, and flame resistance, aging performance, wire diameter specifications, etc.
