A solar DC wire is the connecting wire that is used in a DC solar circuit to transfer current. In a solar system, the electricity produced by the solar panels is in the form of direct current. Hence, to transfer this form of energy to other gadgets like solar inverters and solar batteries, a solar DC wire is required.
Solar Wire At Best Price in India
For best output and constant generation, there are specially designed DC wires called PV wire that connect various components of a solar PV system.There are two single core cables. One is the current-carrying, usually a live red wire, and another is a negative black wire. Both are typically surrounded by an insulation layer.
The DC solar wires from Microtek at Kenbrook solar are double PVC coated and are loaded with a plethora of quality features including high tensile strength, low resistance and resistance from UV, water, oil etc.
The price of a solar wire depends on several features including length, diameter, quality and brand. To know the accurate price of the various DC solar wire options from Microtek at Kenbrook Solar, refer to the table below.

Solar wires are a very important part of any solar power system that we often ignore. To ensure the optimal performance of a solar system, solar cables should be of the proper size.
The gauge or thickness and length of the wire will determine how much current can be safely carried. The longer and skinnier the wire is the more resistance it will have to conduct current. And if the resistance gets too high that will lead to a lot of energy lost or worse. The correct size’s solar DC wire ensures that there is practically no overheating.
How to choose best size solar wire
The size of a solar DC wire depends upon the power output of solar panel that you are going to install. PV cables with cross-sectional areas of 4mm², 6mm², and 10mm² are mostly used. However, the best size solar DC wires according to your solar system is mentioned below.
Up to 300-watt solar panel: 4mm² solar wire.
300-800 watts of solar panel:6mm² solar wire.
800-1000 watts: 8mm² to 10mm² solar wire.
#6. Types of Solar Wire
Various types of solar DC wires differ in conductor material, insulation and flexibility. Some wires work better in high temperatures, high moisture, high UV exposure, or when exposed to fire.
Let’s have a look over these types of solar wires so that you can make an educated purchase decision for your own solar power system.
Copper Solar DC Wires
Copper is the most popularly used metal as a conductor in solar wires. The pure form of copper has surprisingly high conductivity, even greater than aluminium which makes it the most suitable material for conduction in solar installations.
Aluminium Solar DC Wires
Aluminium is commonly used in solar wires as it comes with the advantage of being less expensive. However, compared to copper, the conductivity is less and the energy loss is more. Hence, they are not recommended to be used for interior home wiring.
Solid Core Construction Wire
Solid wires have a more compact diameter for the same current-carrying ability as stranded wires. It can come in various types of insulation that vary in their protective properties. Solid wires are cheaper than stranded solar wires.
Stranded Core Construction Wire
Stranded wires consist of many small wires that allow the wire to be flexible. Since current tends to flow on the outside of a conductor, stranded wire offers more surface area for flow and thus delivers better conductivity than solid.
#7. Features Of DC Solar Wire
The DC solar wires from Microtek at Kenbrook Solar are loaded with many amazing features that make the cables the most popular in the market. All these features are listed below.
#1. Heavy-Duty Solar Cables: The DC solar wires are featured with the best wiring characteristics like good tensile strength and resistance to water, oil, solvents etc.
#2. Double PVC Insulated: The wires are protected with a double layer of PVC coating that reduces the risk of getting an electric shock. Also, this feature makes the wire UV resistant, increasing its life to decades.
#3. 99.99% Pure Copper: The wires are designed with pure copper material that is a great conductor of electricity. As a result, the wires have a high current carrying capacity.
#4. Low Conductor Resistance: Low conductor resistance means the wire will allow most of the current to flow through it offering negligible resistance. Hence the energy loss is minimum.
#5. High Mechanical Strength: A high mechanical strength ensures that the wire is capable of withstanding a considerable amount of stress compelled by physical forces.
#6.Flameproof and Weatherproof: The wire is designed considering several protecting measures that make it flameproof and weatherproof. Hence, you can use the cables even in the harshest climates.
#7. Available in different sizes and length: The DC solar wires from Kenbrook provide you with several length options to choose from. Besides, there are certain combinations of solar connectors equipped with cables.
Power generating capacity and the traveling distance of current should be kept in mind while choosing the best size of solar wires. Mostly, 4mm² to 10mm² wires are used in a solar system. To get the exact idea about the size of the wire, you should contact a solar expert.
