A Guide to Solar Wires

Solar wire is a type of electrical wire that is used to connect solar panels, inverters, batteries, and other components of a solar power system. Solar wire is designed to withstand harsh environmental conditions, such as high temperatures, UV exposure, moisture, and abrasion. The wire is also rated for high voltage and current, as well as low resistance and fire safety.

There are different types of solar wire available in the market, depending on the size, material, insulation, and application. The size of the wire is measured by its cross-sectional area in square millimeters (sq. mm.). The larger the size, the more current it can carry and the lower the resistance. However, larger wires are also more expensive and heavier than smaller wires.

The material of the wire is usually copper or aluminum. Copper is more conductive and durable than aluminum, but also more expensive and heavier. Aluminum is more affordable and lighter than copper, but also more prone to corrosion and oxidation. Therefore, aluminum wires need to be coated with a protective layer to prevent deterioration.

The insulation of the wire is the outer layer that protects the wire from physical damage and electrical hazards. The insulation of the solar wire is usually made of synthetic materials, such as polyvinyl chloride (PVC), cross-linked polyethylene (XLPE), or ethylene propylene rubber (EPR). These materials are resistant to heat, UV rays, moisture, chemicals, and flames.

The application of the wire determines where and how it is used in a solar power system. There are two main types of solar wire: direct current (DC) wire and alternating current (AC) wire. DC wire is used to connect the solar panels to the charge controller or the inverter. AC wire is used to connect the inverter to the grid or the load. DC wire is usually thicker and more expensive than AC wire because it carries higher voltage and current.

The price of solar wire depends on several factors, such as size, material, insulation, quality, brand, and availability. Price may also vary depending on the supplier, location, quantity, and delivery time. Here are some indicative prices of solar wire in India as of July 2023:

1. 6 sq. mm. copper XLPE DC wire: Rs. 80 per meter

2. 10 sq. mm. copper XLPE DC wire: Rs. 120 per meter

3. 2.5 sq. mm. copper PVC AC wire: Rs. 25 per meter

4. 3-phase copper PVC AC cable: Rs. 150 per meter
