What is the current price of solar DC cable in Pakistan?

As of 2026-08-26, the price for solar DC cable in Pakistan varies based on gauge, brand, and retailer. For instance, a 4mm Tin Coated DC Cable (99.9% Pure Copper) United Cable is listed at PKR 29,250 per coil at SolarWalay.com. If you need 6mm cable, a Tin Coated DC Solar Wire (99.9% Pure Copper) United Cables costs PKR 38,250 per coil from the same retailer.

Solar DC Cable Prices in Pakistan

The table below details current prices for various solar DC cables available from Pakistani retailers. Prices are listed per coil or per meter, as specified by the retailer, and reflect observations made on 2026-08-26.

What the price does and does not include

The prices listed in the table are for the DC cable product itself, as specified by the retailer. These figures typically represent the cost of a full coil or a specific length per meter. They do not include any additional components such as MC4 connectors, cable ties, conduit, or other installation materials. The prices also do not account for shipping costs, labor for installation, or any other services. When budgeting for your solar project, remember that the total installed cost will be higher than the sum of individual component prices.

How to choose the correct DC cable gauge

Choosing the correct DC cable gauge is essential for the safety and efficiency of your solar power system. The primary factors to consider are the current flowing through the cable and the length of the cable run. Undersized DC cable is a fire risk because it can overheat under load. It also leads to significant power loss due to voltage drop, reducing the overall efficiency of your solar array.

To size your DC cables, you need to know the maximum current your solar array will produce and the total length of the cable run from your solar panels to your inverter or charge controller.

1. Determine Maximum Current: Check your solar panel's datasheet for its maximum power current (Imp) and short-circuit current (Isc). For a string of panels, the current will be the same as a single panel's current. For parallel strings, you sum the currents of each string. Always use the higher of Imp or Isc for sizing, with an additional safety margin (e.g., 1.25 times Isc).
2. Consider Cable Length: Longer cable runs result in greater voltage drop. You want to minimize voltage drop to ensure maximum power transfer. A common guideline is to aim for a voltage drop of no more than 1-2% for DC circuits.
3. Consult Ampacity Tables: Electrical codes and cable manufacturers provide ampacity tables that specify the maximum current a given cable gauge can safely carry under certain conditions (e.g., temperature, installation method). Since no source we could reach publishes an ampacity table, you should refer to the specifications provided by your inverter manufacturer or a reputable electrical code for your region. As a general rule, a larger gauge (smaller mm² number) can carry less current, and a smaller gauge (larger mm² number) can carry more current.
4. Use a Voltage Drop Calculator: For precise sizing, especially for longer runs, use a voltage drop calculator. You can find online tools, such as a solar voltage drop calculator, to help determine the appropriate gauge based on your specific system voltage, current, and cable length.

Always err on the side of using a slightly larger gauge if you are unsure, as this will reduce voltage drop and improve safety. Proper installation, including appropriate conduit and protection, is also crucial. For more details on ensuring a safe installation, review our solar installation checklist.

What we could not verify

While we were able to gather extensive pricing for DC cables, some related components were not consistently listed or priced across the verified retailers. Specifically, no fetchable listings for MC4 connectors were found across the retailers we checked. Similarly, no specific listings for DC isolators were found, although DC breakers are available and serve a similar protective function.

It is important to note that prices for solar components in Pakistan can fluctuate due to changes in the US dollar exchange rate and import duties. Our prices reflect observations from 2026-08-26. We did not find any retailers publishing a packaged 1kW or 2kW system price; published package ladders typically start at 3kW.
