As solar energy becomes increasingly popular in Pakistan, choosing the right solar components is essential for ensuring efficiency, safety, and long-term cost-effectiveness. Among these components, solar cables play a critical role in transmitting electricity from solar panels to the inverter and battery systems. If you’re planning to install a solar system, knowing the 4mm solar cable price in Pakistan and the 6mm solar cable price in Pakistan is crucial for budgeting and making informed decisions.
In this blog post, we will explore the purpose of solar cables, compare 4mm and 6mm cable specifications, and provide updated pricing trends in Pakistan.
What Are Solar Cables?
Solar cables are specially designed electrical wires that connect different parts of a solar power system. They are manufactured to withstand harsh environmental conditions such as UV rays, heat, moisture, and chemical exposure. The two most commonly used sizes in Pakistan for residential and small commercial installations are 4mm² and 6mm² cables.
4mm vs 6mm Solar Cables: What’s the Difference?
1. Conductor Size and Capacity
4mm solar cables are suitable for shorter distances and lower current loads. They are typically used for rooftop solar systems under 3kW.
6mm solar cables can carry higher currents and are ideal for longer distances or larger systems (above 3kW).
2. Resistance and Voltage Drop
- Thicker cables (6mm) have lower resistance, resulting in less power loss across long distances.
- Using the wrong cable size can lead to overheating, voltage drop, and inefficient system performance.
3. Durability and Installation
- Both sizes are made of tinned copper or pure copper with a durable, double-insulated sheath that is UV and heat resistant.
- Easy to install and compatible with standard solar connectors (MC4 type).
4mm Solar Cable Price in Pakistan (2025)
The 4mm solar cable price in Pakistan varies depending on the brand, quality, and copper content. As of mid-2025, the average market prices are as follows:
Note: Prices may vary slightly based on region and wholesale quantities.
6mm Solar Cable Price in Pakistan (2025)
The 6mm solar cable price in Pakistan is slightly higher due to the increased copper content and thickness. Here’s an updated price list:
Choosing between 4mm and 6mm largely depends on your system size and the distance between your solar panels and inverter.
Factors Influencing Solar Cable Prices in Pakistan
Several factors influence the price of solar cables in the local market:
1. Copper Rates
Copper is the main component in solar cables. A rise in global copper prices directly affects cable costs in Pakistan.
2. Brand Reputation
Well-known brands like Pakistan Cables and Newage may charge higher, but they offer consistent quality, better insulation, and longer life.
3. Insulation Quality
Double-insulated and UV-resistant cables are more expensive but last longer and are safer in extreme weather.
4. Length of Purchase
Buying in bulk or wholesale usually results in lower per-meter pricing. Many installers source 100m rolls for better value.
How to Choose the Right Solar Cable for Your System
1. Calculate Load and Distance
If your inverter is far from your panels or if you’re running a 5kW+ system, opt for 6mm cables to avoid energy loss.
2. Verify Quality
Look for cables with certifications (IEC 60228 or TUV) and check for the use of 100% pure copper. Avoid low-cost copper-clad aluminum (CCA) cables that are less durable.
3. Seek Expert Guidance
Always consult with your solar installer or engineer. An experienced technician can help you select the right gauge and brand for your specific setup.
Where to Buy Solar Cables in Pakistan
You can purchase solar cables in most major cities including Lahore, Karachi, Islamabad, Faisalabad, and Peshawar. Some popular retailers and platforms include:
Wholesale Electrical Markets in Shah Alam Market (Lahore) or Saddar (Karachi)
Online Retailers such as Daraz, OLX, and Solar-specific stores
Authorized Dealers of Pakistan Cables, Newage, or imported brands
Make sure to request an invoice and check for original packaging when buying from physical stores.
Tips to Reduce Solar Cable Costs
Buy Direct from Distributors: Cut out the middleman and purchase from authorized distributors or in bulk.
Check for Government Subsidies: Sometimes, solar incentives or programs may include discounts on approved accessories.
Don’t Compromise on Safety: Choosing a cheaper, sub-standard cable can lead to fire hazards and system failures.
Conclusion
Whether you’re installing a small residential solar system or a larger commercial one, understanding the 4mm and 6mm solar cable prices in Pakistan will help you plan better. While 4mm cables are great for low-power setups, 6mm cables offer better performance for higher loads and long-distance runs. Always balance price with quality, and invest in certified, durable cables to ensure safety and long-term savings.
