FAQ From Customers
-
What is a solar cable?
A solar cable is a specialized electrical cable designed to transmit power between solar panels, inverters, and battery storage systems in solar energy systems. These cables are built with UV-resistant insulation and weatherproof sheaths to ensure long-lasting performance in outdoor conditions. Solar cables typically have high conductivity to handle the power demands of solar energy applications, and are designed to be durable, flexible, and able to withstand extreme temperatures and moisture. -
Do I need 4mm or 6mm solar cable?
The choice between 4mm or 6mm solar cable depends on the distance between your solar panels and inverter, as well as the current your system will carry. 6mm cables are typically used for longer distances or systems with higher current ratings, while 4mm cables may be sufficient for smaller systems or shorter distances. Always consult with an electrical professional to ensure the correct cable size for solar power transmission and to meet safety standards. -
What is a solar DC cable?
A solar DC cable is a type of direct current (DC) cable used specifically for connecting solar panels to inverters in a solar energy system. DC cables are designed to handle the lower voltage and higher currents typical of solar power systems. They are built with UV-resistant, fire-resistant insulation and durable sheathing to ensure safe operation in outdoor conditions. Solar DC cables are essential for the efficient power transmission between solar panels and inverters. -
What are the different types of solar cables?
There are several types of solar cables, each designed for specific applications:
Solar PV cables: Used to connect solar panels to inverters and battery storage systems, typically DC cables with cross-linked polyethylene (XLPE) insulation.
AC solar cables: Used for alternating current (AC) connections between inverters and the electrical grid.
Solar DC cables: Designed specifically for direct current connections within solar power systems.
Underground solar cables: Built to withstand harsh underground conditions with waterproof and UV-resistant insulation.
These cables are available in various sizes, including 4mm and 6mm, depending on the system's voltage and current needs. -
Why are solar cables UV resistant?
Solar cables are designed with UV-resistant insulation to protect them from the harmful effects of ultraviolet radiation. UV resistance is crucial for cables used in outdoor environments, as prolonged exposure to sunlight can cause insulation degradation, leading to safety risks and reduced lifespan. UV-resistant solar cables ensure long-lasting durability and safe operation in solar power systems, even in harsh weather conditions and outdoor installations.
