5 minutes to know the important role of photovoltaic cable in photovoltaic plant

Since December 2020, the frequency of mentioning the word "photovoltaic" has increased significantly after China announced "carbon peaking and carbon neutrality" at the Climate Ambition Summit. However, with the passage of time and the increase in photovoltaic application environments, some photovoltaic power plants The problems and challenges encountered are slowly emerging.

Reduced power generation efficiency of old photovoltaic power plants

Many power stations have produced far less power than expected or even no power generation. There are many reasons for this situation, abnormal attenuation of components, damage to components, abnormal inverters, etc. will greatly reduce the power generation and component life.

The safety requirements of photovoltaic power plants are getting higher and higher

According to incomplete statistics, there have been 76 fire accidents in photovoltaic power plants in recent years, many of which are caused by equipment problems, component hot spots, and ground faults. In addition to the above reasons, high-power components and multi-scenario power generation will also increase the hidden dangers of accidents.

It is difficult to repair the photovoltaic cables laid under the modules

When the photovoltaic cable is aged or worn, its insulation capacity is reduced and leakage current is generated. The inverter cannot be turned on due to leakage current, which is common after rain and snow. If the optical cable under the module is not repaired in time, it will further wear and cause arcing and high temperature, which will lead to fire.
