Photovoltaic cables play an important role in solar power generation systems, and the correct selection and installation of photovoltaic cables is essential to the performance and safety of the system. This article will introduce the need to pay attention to the purchase and installation of photovoltaic cable, in order to ensure the reliability and efficiency of the system.

Photovoltaic cables transmit DC power in solar power generation systems and assume the task of connecting photovoltaic modules, inverters and other equipment. When purchasing photovoltaic cables, first ensure that products that meet national and industry standards are selected. High-quality photovoltaic cables should have high temperature resistance, ultraviolet resistance, anti-aging and other characteristics to ensure the long-term stable operation of the system.
Secondly, according to the system design power and current size to choose the appropriate cable specifications. Too thick or too thin cable will affect the performance of the system, and even there is a security risk. In addition, the quality of the copper core of the photovoltaic cable also needs to be paid attention to, and the high-quality copper core can effectively reduce the resistance and reduce the line loss.
When installing photovoltaic cables, excessive bending or stretching should be avoided to avoid affecting the electrical conductivity of the cable. In addition, in the wiring should pay attention to maintain a good connection, to avoid poor contact or short circuit phenomenon. Regular inspection and maintenance of photovoltaic cables is also the key to ensure the normal operation of the system.
In short, when selecting and installing photovoltaic cables, we must pay attention to the details of product quality, specification matching, and installation process to ensure the safe and efficient operation of the system.
