When it comes to solar installations, many people try to cut costs by going for cheaper options, especially with wiring. One of the most common mistakes is using 6mm² PV wires when 10mm² is the better and smarter choice. Let’s break down why:
✅ 1. Future-Proofing Your System
Most people install solar to reduce dependence on PHCN or generators—and as time goes on, they want to add more batteries or panels. If you install 6mm² wires now, and later upgrade your system, you may have to change all your wires again to handle the higher current. That’s double spending.
✅ 2. Reduced Voltage Drop = More Power
10mm² wires can carry more current with less resistance. That means less voltage drop, and more efficient power delivery from your panels to your charge controller and inverter. With 6mm², you lose more power, especially over long distances.
✅ 3. Safety First 🔥
Undersized wires like 6mm² can overheat when overloaded. This can cause insulation damage, short-circuits, or even fire hazards. 10mm² gives you extra capacity and peace of mind.
✅ 4. Cost Difference is Small, but the Benefits Are Huge 💰
The price gap between 6mm² and 10mm² wire may not be as big as you think—but the cost of changing wires later is much higher. You’ll need to buy new wires and pay a technician again.
🚫 Stop Thinking Short-Term
It might feel like you're saving money now by choosing 6mm², but in the long run, you’re setting yourself up for extra cost, stress, and safety risks.
👷♂️ Our Advice as Solar Experts:
Whenever you're installing solar—whether it's 1kVA or 10kVA—go for 10mm² PV wires from the beginning. It's the wise choice for durability, efficiency, and future expansion.
