If you are looking at your electricity bill in January 2026 and wondering if solar is finally “worth it,” the short answer is yes. In fact, 2026 might be the single best year we’ve seen for solar ROI (Return on Investment) in Ireland.
With the average unit price of electricity still hovering around 36.34c per kWh and the extension of key government incentives, solar panels have moved from a “luxury eco-upgrade” to a shrewd financial defense against rising living costs.
Here is the data-driven reality of going solar in Ireland this year, and how you can use our new Solar Savings Estimator to see exactly what you’ll save.
1. The Numbers: Why 2026 is the Year to Switch
The financial case for solar in 2026 is built on three pillars: High Savings, Low VAT, and Smart Grants.
- Avoid High Grid Rates: While inflation has cooled, electricity prices haven’t returned to pre-crisis levels. By generating your own power, you are effectively buying electricity at a fixed cost of 6c–8c per unit (the lifetime cost of the system) versus paying the grid average of ~36c.
- 0% VAT is Here to Stay: The government has confirmed that the 0% VAT rate on the supply and installation of solar panels for homes will continue in 2026. This instantly saves you 13.5% on the total cost compared to a few years ago.
- The €1,800 Grant Remains: Despite rumors of a reduction, the SEAI Solar PV Grant remains capped at €1,800 for 2026. This is a direct cash payment that significantly lowers your upfront investment.
- Get Paid to Export: You don’t just save; you earn. Under the Clean Export Guarantee (CEG), energy providers are paying between 18.5c and 25c per kWh for the surplus electricity you send back to the grid. Plus, the first €400 of this income is tax-free thanks to the extended tax disregard.
The Bottom Line: A standard residential system (e.g., 4kWp) typically pays for itself in just 5 to 7 years. After that, you are essentially generating free electricity for the remaining 20+ years of the system’s life.
2. Stop Guessing: Try the QMAC Solar Savings Estimator
We know that “average” savings don’t mean much to your bank account. That is why we built the QMAC Solar Savings Estimator (pictured below).
Most calculators ask for complicated technical details you don’t have. Ours starts with the one number you definitely know: Your Bill.
How It Works:
- Enter Your Bill: Simply type in your average bi-monthly electricity bill (e.g., €250).
- See Your System: The tool instantly calculates the Recommended System Size (in kW) perfectly matched to your spend—so you don’t overpay for panels you don’t need.
- Real-World Impact: We translate “kilowatt-hours” into real life. See how many Kettles Boiled, Laundry Loads, or Phone Charges your roof could power for free every year.
- The Verdict: Finally, see your estimated Annual Savings side-by-side with what you would spend if you stuck with the grid (Annual Spend No Solar).
3. Beyond the Bill: BER and Value
It’s not just about cash flow. Installing solar panels is one of the fastest ways to improve your home’s BER (Building Energy Rating). In 2026, a B3 rating or higher unlocks cheaper “Green Mortgage” rates from most Irish banks, potentially saving you thousands more in interest repayments over the life of your mortgage.
Summary: Is it worth it?
| Factor | 2026 Status | Verdict |
| Grid Electricity Price | High (~36c/kWh) | Solar Wins |
| Installation VAT | 0% (Permanent) | Solar Wins |
| SEAI Grant | €1,800 (Confirmed) | Solar Wins |
| Export Payments | ~18.5c – 25c/kWh | Solar Wins |
