Are solar panels worth it in Ireland in 2026?
Solar panels are absolutely worth it. They are a great way to generate clean, renewable energy for your home or business. With solar panels, you can reduce your energy consumption and carbon footprint for years to come. But will they pay for themselves? Solar panels are often marketed as a way to save money, but they can also be a way to make money.
Through microgeneration you can earn money for any electricity solar panels produce that you do not use. We currently offer our residential customers a rate of 18.5 cent per kWh exported to the grid.
Many people install solar panels for various reasons, such as wanting to use greener energy. It's important to understand when you'll see a financial return on your investment. With various incentives and support schemes available, now is a great time to make the switch to solar. In this blog post, you’ll learn if solar panels are worth the investment, the costs involved, and how much you really can save by installing solar panels in your home or business in Ireland in 2026.
How much do solar panels cost?
When we talk about “solar panels” in Ireland and the “cost of solar panels”, what we’re really talking about is the cost of a solar PV system. The panels are an important part of the equation, but to generate energy, you will need solar PV panels and associated equipment, in other words, a complete solar PV system.
For homeowners, the cost of installing solar panels can range between €6,000 and €16,000, depending on system size, panel type and installation requirements. As a general guide, an average three-bedroom house in Dublin would require between 8 and 10 solar panels to significantly cover its electricity needs.
At Energia, we offer tailored solutions to meet the needs of both residential and commercial customers. Our smart solar bundle offers customers savings of up to €750 on solar installation, along with an 18.5 cent microgeneration export rate. Our powerhouse 550w solar panels are designed to be energy efficient and space-saving, generating more power per square meter than many other solar panels in the market.
For businesses, the cost of solar panels can vary significantly depending on the size of the premises and energy requirements. Commercial solar panels tend to be larger and more complex than residential installations, which can affect the overall cost. But businesses and homeowners can take advantage of schemes like the SEAI Solar PV Grant, which offers financial support to make the switch to solar easier.
Paying for your solar panels
Wondering how to finance your solar panels? There is some good news. Investing in solar panels is not just environmentally friendly choice, it’s also a smart financial move. Here’s how you can make it happen.
As mentioned previously, homeowners can take advantage of the SEAI Solar PV Grant and other SEAI home upgrade grants available in Ireland. If you’re a homeowner from January 2025, the Solar PV grant is:
- €700 per kWp up to 2kWp
- €200 for every additional kWp up to 4kWp up to a limit of €1,800
On top of that, Energia’s solar bundle offers customers on any Energia Smart tariff a saving of €750 on solar panel installation. The grants that are currently available make it easier to go solar, while reducing your reliance on the grid and carbon footprint.
How much can you save with solar PV panels?
Energia’s solar panels can help you generate money over time, let’s break down the potential savings.
A well-installed Solar system should reduce your electricity bills. How much is saved is dependent on several factors such as: the number of panels installed, wattage and efficiency of the panel, roof orientation, shading; general household energy consumption and how much you export back to the grid.
However, you must bear in mind the cost to install the Solar system and how long it will take to pay back this cost back. When you receive a quote for a Solar PV system the seller usually gives an indication of how long the PV system will take to pay for itself. This is quite a general calculation and is not unique to your house and how you use energy within the household so it should be viewed as an approximation. Seasonality is also a factor to consider. The system will produce more electricity in the brighter months when demand for electricity for lighting and space heating is less.
If you are at home during the day, you can make the most of the electricity generated by the Solar PV system by using household appliances, especially if it’s a bright sunny day. If the house is unoccupied during the day there are a number of avenues you can use to your advantage:
- Export the electricity and get paid for each unit exported
- Use a diverter to send any excess electricity to heat your hot water tank
- Send the excess electricity to a battery for you to use later. Many households now add solar battery storage to maximise the energy they generate.
Diverters and batteries are optional extras, and you have to consider how you use and manage their household energy prior to purchasing these extra options. Purchasing a battery allows your Solar PV system to become dynamic and responsive but batteries are still expensive to buy and need to be actively managed to get the most out of them. Many homeowners therefore ask whether solar panel batteries are worth it once upfront costs and potential savings are considered.
Having said that, a typically sized system on a 3 bed semi-detached could save between €500-800 euro per annum, with a larger system potentially generating up to €1600. Bear in mind that these savings can fluctuate based on the above factors, as well as with the price of energy through the year.
How long do they last?
Solar panels are built to last. The solar panels on the market have a life span of 20-30 years. There are newer versions coming on the market all the time with longer lifespans. The lifespan of a solar panel is long enough to more than recoup the cost of installation, by helping you save on costs such as heating water. Their durable design and minimal maintenance requirements, makes solar panels a reliable source of electricity for your home or business. With proper care and maintenance, such as cleaning to remove dirt or debris, solar panels can even exceed their expected lifespan, allowing you to reap the benefits of renewable energy for years to come.
How long does it take for solar panels to be paid back?
In Ireland, individuals typically recoup the costs of their solar panels within 5-12 years. This payback period can depend on the energy prices and available incentives. At Energia, we understand the importance of making solar energy accessible and cost-effective for our customers. That’s why we offer tailored solutions to meet your needs. With our smart solar bundle, customers can enjoy savings on installation costs or SEAI grants to offset the initial investment.
Pros and cons of solar panels
Solar panels offer numerous advantages, making them a smart investment for modern living, although there are a few drawbacks worth considering when looking at the advantages and disadvantages of solar energy. Solar energy produces no greenhouse gases during operation and helps reduce reliance on the world’s finite fossil fuels. Solar panels require little maintenance, generally last between 25 and 30 years, and can still generate electricity even on cloudy days in Ireland. While there is an upfront installation cost, panels can help lower long-term electricity and hot water bills, and households and businesses in Ireland can benefit from grants, tax incentives and VAT exemption. On the other hand, they do require suitable roof space, battery storage adds to the overall cost if you want to use solar power at night, output can vary depending on weather and season, and some homeowners may not prefer their appearance.
FAQs: Are solar panels worth it?
What happens after 20 years of solar panels?
