How Solar Can Reduce Your Energy Bills by Up to 100%

With the right system size and battery storage, Irish homes and businesses can achieve complete energy independence. Here's how solar can transform your energy costs.

Understanding Solar Savings

The average Irish household spends €2,500-€3,500 per year on electricity. A properly sized solar PV system can reduce this to near zero, especially when combined with battery storage.

The Role of Battery Storage

While solar panels generate electricity during daylight hours, battery storage allows you to use this energy in the evening when demand is highest. Modern battery systems like Tesla Powerwall and Huawei LUNA can store 5-15 kWh.

Export to the Grid

Through the Clean Export Guarantee, you can sell excess electricity back to the grid at competitive rates. This additional income further improves your return on investment.

Real-World Example

A 6 kWp system with 10 kWh battery storage typically costs €15,000-€18,000 after grants. With savings of €2,000+ per year, the payback period is around 7-8 years, after which electricity is essentially free.
