Application
Photovoltaic wires are cables used in solar power systems. Photovoltaic lines connect solar power generation system components like panels, inverters, and controllers. They transmit electrical energy and signals. Photovoltaic wires must be able to withstand a lot of different conditions to work well in solar power generation systems.

What is Solar cable?
Solar wires are usually divided into different types according to their structure and use. Common types of solar wire include
Single Core solar cable: Single-core photovoltaic wire is the most common type. It consists of a single conductor and is suitable for general photovoltaic power generation systems.
Double-core solar cable: Double-core photovoltaic wire is composed of two conductors and is usually used between photovoltaic panels connected in DC series. It can reduce the number of cables and simplify installation.
Multi-core photovoltaic cable: Multi-core photovoltaic cable is composed of several conductors and is suitable for some special photovoltaic power generation systems, such as systems that need to transmit power and signals at the same time.
Multi-core photovoltaic cable: Multi-core photovoltaic cable is composed of several conductors and is suitable for some special photovoltaic power generation systems, such as systems that need to transmit power and signals at the same time.
Distributed solar cables: used in distributed photovoltaic power plants or distributed photovoltaic power generation systems. They usually use cables with a smaller cross-section and are suitable for distributed power generation systems with low power.
These types of photovoltaic cables differ in structure and use. When selecting, you must make a reasonable choice based on the design requirements and installation environment of the specific photovoltaic power generation system.
