DC solar cable in Pakistan currently costs between PKR 150 and PKR 900+ per meter, depending on the cable size and material, with a full home solar installation typically needing PKR 9,999 to 14,999 worth of DC cabling across multiple sizes. Since DC cable carries power directly from your solar panels to the inverter, getting the right size and quality matters as much as getting a good price. This guide breaks down 2026 pricing by cable size and what actually affects the cost.

What Is DC Cable and Why It Matters for Solar Systems
DC (direct current) cable carries the raw electricity generated by solar panels to the combiner box, isolators, and finally the inverter — before it’s converted to usable AC power. Unlike ordinary household wiring, proper solar DC cable is double-insulated, UV-resistant, and rated for up to 1500V DC, since it’s exposed to direct sunlight and outdoor weather on the rooftop for years at a time.
Using the wrong cable — whether undersized or made from low-grade material — leads to voltage drop, energy loss, overheating, and in worst cases, fire risk at connection points. This is why DC cable, despite being a small line item compared to panels and inverters, deserves real attention rather than being an afterthought in your solar budget.
DC Cable Price in Pakistan by Size
Pricing scales with the cable’s cross-sectional area (measured in mm²), since thicker cable carries more current with less resistance. Here’s what the market looks like in 2026:
2.5mm² DC Cable
- Price range: PKR 120 – 180 per meter
- Suitable only for very short runs or very small systems with low current.
4mm² DC Cable
- Price range: PKR 150 – 220 per meter
- The most common size for small residential installations (up to around 3kW), where panel-to-inverter runs are relatively short.
6mm² DC Cable
- Price range: PKR 220 – 320 per meter
- Commonly used for mid-sized home systems (5kW–7kW) or when cable runs are longer than average.
10mm² DC Cable
- Price range: PKR 350 – 500 per meter
- Used for larger residential or small commercial systems, or where current loads are higher.
16mm² DC Cable
- Price range: PKR 600 – 900+ per meter
- Designed for industrial-scale or high-capacity PV installations where current and run length both demand a thicker conductor.
Total system cost: Most home solar installations use a mix of cable sizes rather than just one, so total DC cabling typically adds up to around PKR 9,999 – 14,999 for a standard residential setup — a relatively small slice of the overall solar system budget, but not one to skimp on.
What Affects DC Cable Prices in Pakistan
- Cable size (mm²): Larger cross-sections cost more per meter but reduce voltage drop and energy loss over longer distances.
- Conductor material: Tinned copper (TIN CU) resists corrosion and offers better long-term conductivity than plain copper, but costs more upfront.
- Insulation type: High-grade XLPO insulation handles heat and UV exposure better than basic PVC insulation, extending cable life on an exposed rooftop.
- Voltage rating: Cables rated for 1500V DC — the standard for modern PV systems — typically cost more than lower-rated alternatives.
- Brand and origin: Locally manufactured cables are generally cheaper, while imported options often carry a premium for consistent quality control.
- Run length and system size: Longer cable runs and larger systems naturally require more total cable, increasing the overall cost even if per-meter pricing stays the same.
Choosing the Right DC Cable Size
The right size depends on your system’s current output and how far your panels are from the inverter:
- Short runs, small systems (up to 3kW): 4mm² is usually sufficient.
- Medium systems (5kW–7kW) or moderate cable runs: 6mm² is the safer choice.
- Larger systems or long cable runs: Step up to 10mm² or 16mm² to minimize voltage drop.
As a general rule, longer cable runs need a thicker cable even if the system size stays the same — voltage drop increases with distance, and undersized cable on a long run will waste energy and generate unnecessary heat.
Tips Before You Buy DC Cable
- Don’t buy on price per meter alone — check whether the cable uses tinned copper and proper XLPO insulation, since cheaper cables often cut corners on both.
- Match the cable to your inverter and panel current, not just the system’s advertised size — an installer or supplier can confirm the correct rating.
- Buy slightly more length than the exact measured distance to account for routing around obstacles and connection slack.
- Check the voltage rating — confirm it’s rated for at least 1500V DC if you’re running a standard modern PV setup.
- Pair it with the correct DC breaker (DC MCB) rated for your string voltage, since AC breakers cannot safely interrupt DC current and pose a fire risk if mismatched.
Final Thoughts of dc cable price in pakistan
DC cable prices in Pakistan in 2026 range from about PKR 120 per meter for small 2.5mm² cable to over PKR 900 per meter for heavy-duty 16mm² industrial cable, with most home solar systems spending PKR 9,999–14,999 total on cabling. While it’s a small part of your overall solar budget, choosing the correct size and quality directly affects your system’s efficiency, safety, and lifespan — so it’s worth getting right rather than choosing on price alone.

FAQs of dc cable price in pakistan
What is the price of DC cable in Pakistan in 2026?
DC solar cable prices range from about PKR 120 to PKR 900+ per meter depending on size, with a typical home solar system needing PKR 9,999 to 14,999 worth of cable in total.
What size DC cable do I need for a 5kW solar system?
Most 5kW systems use 6mm² DC cable, though longer cable runs may require stepping up to 10mm² to reduce voltage drop.
Is tinned copper DC cable worth the extra cost?
Yes, for rooftop solar use. Tinned copper resists corrosion better than plain copper and maintains conductivity longer under outdoor exposure.
Can I use ordinary electrical wire instead of solar DC cable?
No. Ordinary house wire isn’t rated for outdoor UV exposure, extreme temperatures, or the voltage levels used in PV systems, and using it increases fire risk.
What voltage rating should solar DC cable have?
Standard modern PV systems use cable rated for 1500V DC, which handles typical residential and commercial solar string voltages safely.
Do I need a DC breaker with my DC cable?
Yes. A DC-rated breaker (DC MCB) is required to safely interrupt DC current in case of a fault — an AC breaker cannot extinguish a DC arc and poses a serious fire risk.
