In Energy Tips, Solar Advice, Solar Panels

Thinking of joining the solar energy revolution that’s growing across the country? Then you might be wondering: Just how much do solar panels cost in Ireland, anyway?

It’s a good question. Before you commit, it makes sense to get an idea of what you’ll have to invest, and what kind of return you can expect. In this post, we’ll help you work out the finances involved based on your situation and needs. Plus, we’ll cover the long-term benefits of this investment: helping you decide whether the switch to solar is worth it.

Psst…There’s no blanket approach to decent solar panel installations. Numbers will vary depending on your home, circumstances and a few key factors. So the figures we provide in this post are simply guidelines based on the average costs of what would be considered a “standard family home”. 

Still, hopefully, they’ll provide a decent baseline for you to work out what you can afford. So let’s get started!

Factors Influencing the Cost of Solar Panels in Ireland

How much does a solar panel cost? Well, how long is a piece of string?! Ok, the first question might be a little easier to work out – but it still requires more information to get a decent answer.

The cost of installing solar panels in Ireland depends on factors such as:

  • Location: Different provinces receive differing hours of sunlight
  • Orientation: The direction in which your home faces
  • Roof Space: Not only the size, but whether any incline or obstacles might affect its potential output
  • Energy Consumption: The electrical appliances you use might determine your Solar PV system, and the cost of solar panel installation 
  • PV Panel Type: Solar panel prices vary depending on the materials used and their potential yield
  • Number of Panels: A minimum amount might be needed to cut those energy bills
  • PV Panel Quality: A range is available – based on materials, installation providers and the efficiency of both
  • Batteries, Diverters & Inverters: How you store, direct and transform solar power impacts your energy consumption, and how much it might cost you


Psst…Remember, you don’t have to pay anything for the source of energy itself – that’s free, thanks to the sun. What you are paying for is the process of harnessing the sun’s energy and converting it into electricity and/or heat you can use in your home. 

The higher the quality of the system you choose, the higher your initial investment may be. But the benefit of that is a streamlined, simple and clean solution that covers either a good portion of, or even all of your household’s energy needs, well into the future


A Breakdown of Solar Panel Costs

How much are solar panels in Ireland? Well, a standard Irish family home – which we could classify as a 3-bedroom, semi-detached house – might spend anywhere between €3,000 and €15,000 on solar panel installation. 

That’s quite a gap: and while it’s tempting to go with the lowest offer from a solar panel installation company, we would advise you to question why it’s so low. Maybe their materials aren’t quite up to scratch, so you could end up paying more later to install more panels. 

Or maybe the company itself hasn’t got the expertise or dedication that the project requires. Remember, installing Solar PV panels shouldn’t be a “fit and forget” process. You’ll want an ongoing relationship with your provider, knowing that you can always contact them for further support. 

After all, solar power is growing in Ireland, which is a positive thing – but with over 350 installers in the industry of varying quality, many of these companies won’t be around in the future if your panels need servicing or if you want to expand on your system.

Meanwhile, figures at the top end might give the illusion of higher performance; but the provider could be recommending a system that’s too big for your energy consumption needs or your specific home. 

There’s a lot to consider, so we’d suggest familiarising yourself with the factors involved in shopping for solar: getting a rough idea of how many panels you might need first based on your circumstances, then choosing a registered and experienced company for installation support.

Understanding the Long-Term Value of Solar Panels

You’ve seen the figures. And now that you know a little more about what you can expect to pay, what kind of benefits or rewards can you expect to see as a result? 

Get a Return on Investment

We’ve all seen how household bills have grown over the past few years – and the trend looks set to continue. Having a renewable (and free!) energy source to hand is a surefire way to offset some of those expenses – while providing peace of mind with greater energy independence and control over your costs. 

But to make the most of this energy source, you’ll need to harness it in a strategic way, with the help of a registered, experienced company. 

When you do, over time you could see a significant reduction in your home energy bills. The amount you’ll save by channelling solar power can put a serious dent in those bills, cut them in half or even cover them entirely…imagine!

Of course, like the saying goes, you get out what you put in. And the more panels you install initially (or actually, the system you choose that can generate the most power based on the most unobstructed roof space you have), the better your return. 

That’s why it’s important to choose a reputable and established solar installation company in Ireland: one that can provide a detailed assessment from the outset to recommend what’s best for your individual home. Over 80% of Irish solar companies launched in the past three years, whereas Caldor Solar have been in business since 2015. So you can be sure of our expertise…and our longevity, should you need us in the future.

Audit Your Energy Efficiently

The great thing about switching to solar is that it asks you to look at your current energy consumption – and just the act of doing so will often encourage you to ‘clean up’ where you can to gain more energy independence.

You might see how and where you can replace energy-draining electrical appliances with more efficient alternatives (for instance, ones with LED bulbs). Even changing a few habits – like only putting on the dishwasher when it’s full – can make a massive difference to your household energy consumption. 

Years back, energy providers would recommend batteries to store surplus energy at night. However, with the Clean Export Guarantee (CEG) now available to homeowners who export excess renewable energy to the grid, Caldor Solar advises skipping the battery in most cases – choosing extra panels and perhaps a power diverter instead. (A power diverter is a pretty cost-effective way of using up that extra solar electricity by heating water, and costs around €200–€500.)

Once you spend a little time cleaning up, cutting down and getting creative with your electricity, you may find that you don’t actually need as many solar panels to cover your costs. So at Caldor Solar, we’d advise you to run a ‘home energy audit’ before installing a Solar PV system. After all, with a more energy-efficient home, the further your solar panels can go.
