The Right Cable Size for Irish Solar Installations
We use 6mm to 10mm DC cables for all our solar panel installations. This isn’t a random choice. It’s carefully calculated to support the higher voltages and currents produced by modern, high-efficiency solar panels.
Why DC Cable Size Matters
Solar panels generate DC (direct current) electricity that flows through cables to your inverter, where it’s converted to usable AC power for your home or business.
Using properly sized DC cables is critical for several reasons:
Safety First: Undersized cables can overheat under high current loads, creating fire hazards. Our 6mm to 10mm cables safely handle the electrical load from today’s powerful solar panels, which can produce significantly more current than older models.
System Efficiency: Cables that are too thin create resistance, leading to voltage drops and energy losses between your panels and inverter. Properly sized cables ensure maximum energy transfer and optimal system performance.
Long-Term Reliability: Quality DC cables rated for outdoor solar use, combined with appropriate sizing, ensure your system operates reliably for 25-30 years without degradation or safety concerns.
Compliance: SEAI-registered installers like NuSolas Energy follow strict electrical standards that mandate proper cable sizing based on system voltage, current, and installation conditions.
Professional Installation Makes the Difference
Choosing the correct DC cable size requires expertise in electrical engineering and understanding of Irish weather conditions. Our SEAI-certified team ensures every cable is properly specified, installed, and protected for decades of safe operation.

Frequently asked questions
- Do solar panels work well in Irish weather?Yes. Modern solar panels are designed to work with daylight rather than direct sunlight, making them highly effective in Ireland’s climate. Even on cloudy or overcast days, solar panels generate electricity, helping you save on energy bills year-round.
- What is the cost and return on investment for solar panels and heat pumps in Ireland?A typical air-to-water heat pump installation costs between €13,000-€17,000, depending on your home size and system specifications. Solar panels and heat pumps offer strong long-term savings. Solar PV systems typically pay for themselves in 3-4 years, while heat pumps often achieve a return on investment in around 6 years, depending on factors including insulation, energy usage, and home size.
- How can I save on energy costs with solar panels and air-to-water heat pumps?Installing solar panels in Ireland can significantly reduce your electricity bills, with households saving up to 80% annually. An air-to-water heat pump captures heat from the outside air and efficiently heats your home and hot water. Many homeowners combine heat pumps with solar PV systems to maximise energy savings and lower their carbon footprint.
- What grants and incentives are available for solar panels and heat pumps in Ireland?NuSolas Energy offers comprehensive assistance with SEAI grant applications, helping Irish homeowners access funding and simplify the installation of energy-efficient solutions. Available grants and incentives include: 1. Solar PV Grant: Up to €1,800 per household, plus VAT reductions and export credits for surplus electricity. 2. Heat Pump Grant: Up to €6,500 for houses and €4,500 for apartments, along with a €200 grant for a technical assessment.
- Why choose NuSolas Energy for solar panels and heat pumps in Ireland?NuSolas Energy is a trusted Irish installer of solar panels and heat pumps, providing energy-efficient, reliable heating solutions with comprehensive product and workmanship warranties.
