Solar Panel Installation Costs

The cost of solar panels in Ireland depends on the size of the system, i.e. the total number of PV modules that are installed.

A typical solar panel system costs between €5,000 and €10,000 including installation, with an array of 10 individual panels costing about €7,500.

The overall costs will depend some other number of factors too, such as the quality of the PV modules themselves.

But the two most important decisions for homeowners are:

  1.  Selecting the right number of PV panels.
  2. Choosing the best solar installation company.

Reliable installers will help you through the decision making process, but there are some other things that you should consider before installing a solar system.

How many solar panels do you need to install?

Deciding how many solar panels to install is extremely important as this will affect the payback period, your annual savings and the initial cost. Most homes in Ireland opt for solar systems of between 6 and 16 solar panels.

The exact number of panels that is right for you will depend on your electricity bills and how much you want to save. A good target is 75% of your annual energy bills being covered by solar.

In Ireland, the average household electricity consumption is 4,200 kWh, according to the Commission for Regulation of Utilities (CRU). So the number of solar panels needed to generate 3,150 kWh of electricity (75% of the average) is between 8 and 10.

Choosing the Best Solar PV Installer

To help you decide how many solar panels to install, choosing a reliable solar panel installer is crucial to ensure a smooth process from start to finish. There are a few ways that you can narrow down the search for the best solar installation company.

Things to Consider Before Installing Solar Panels

As well as choosing the right number of panels and the best installer, there are some other things to think about pre-installation, including roof size, orientation, and SEAI grants.

How Much Roof Space is Available

The amount of roof space you have can limit the number of panels you can have installed. Eight panels would take up around 17 m2 of roof space, 10 panels would require 20m2, and 12 panels would need 25m2.

This will depend on the size of the panels, but most panels are of a similar size. For example, LONGi Hi-Mo X6 solar panels are 1722mm x 1134 mm, while BAUER Glass solar panels are 1762mm x 1134mm.

Roof Orientation

The roof’s orientation is also important to consider. South facing roofs are the best for solar power in Ireland as they get the most direct sunlight overall. East-west facing roofs are also suitable, and will get the most light in the mornings and evenings, while north facing roofs are not ideal for solar panels.

The small minority of homes with flat rooftops can have solar panels oriented in any direction.

SEAI Residential Solar Grants

There has never been a better time to install solar panels in Ireland, especially as the SEAI home solar grant is set to be reduced again at the start of 2025. This means that if you install solar panels in 2024, you will likely receive the full maximum residential solar grant amount of €2,100 before it is cut to €1,800.

Solar Panel Installation Steps

The installation process is quick and straightforward, and it will cause minimal disruption to your life as your solar installer takes care of everything behind the scenes. But it’s always good to be aware of the different stages of the journey.

After choosing your solar panel installer, they will conduct a site visit to examine your home’s roof to determine the optimal layout for your panels.

You should also inform the installer about details such as your energy consumption to determine what size of solar PV system you need.

After the site visit, and the signing of a deal with your installer, an engineer will also visit to assess more technical information and determine how suitable your home currently is for a solar system.

The roof must be examined to ensure that it is structurally sound enough to take the solar panels, and what needs to be done to wire the panels into your home. Your home’s electrical system will also need to be examined to determine if any upgrades are required.

Now that you know what you want, it’s time to apply for that all important grant funding from the SEAI, which your solar installation company will complete for you.

Your chosen installer will source the best PV panels for you. You should consult your installer about the panels they use, and whether you will need a battery to accompany the panels.

Now that all the elements of your solar energy system are ready to go, it’s time to have the installer hook them up.

  1. Set up Scaffolding: The first step for the installation process will be to erect temporary scaffolding around your home to give the contractor access to the roof.
  2. Install Solar Panel Mounts: These racks will be attached to your roof to support the solar panels, and ensure that they are tilted at the right angle.
  3. Mount the Solar Panels: Your solar panels are now ready to be affixed to the mounting structure to ensure they remain stable.
  4. Wiring: Electrical Wiring must be done to connect the solar panels to your household electrical system, and the solar inverter needs to be connected to convert the DC electricity to usable AC.

Now you have your fully installed solar energy system energy system and you can start using your free renewable electricity.

For a household solar panel installation, you must have a post works BER assessment carried out to show how the improvements have affected the building’s energy rating. Your installer must also complete a Declaration of Works form, and submit it to claim the SEAI grant.

Solar Panel Installation Steps

7 Years

A typical solar installation is fully paid back within 7 years. All solar panels we recommend are under warranty for 25 years, so you will enjoy at least 17 years of free energy generation.

0% VAT

As of 10 May 2023, the government has removed all VAT on solar installation and solar panel supply. This means solar has never been more affordable!

Government Grants

There is a range of government grants available for all new solar installations. Our team will guide you through the application process.

Can you install solar panels DIY?

It is technically be possible for people to install their own solar PV systems, but it is highly recommended that you leave the job to a qualified installer.

Solar energy installation is a complicated task that will require heavy physical labour on your rooftop, and extensive knowledge of electrical wiring to connect the system.

In addition, in order to qualify for SEAI grant funding, the solar system must be installed by a registered contractor.

Planning Permission for Solar Panel Installation

Planning permission is no longer required for rooftop solar panels in Ireland, aside from a few restrictions depending on your location.

In most areas homeowners and businesses are allowed to erect unlimited amounts of rooftop solar panels without needing planning permission.

In 43 Solar Safeguarding Zones (SSZs) near airports, aerodromes, and helipads, solar panel installations of up to 300m² are allowed without needing planning permission.

For ground-mounted solar PV panels, up to 25m² worth of panels can be erected without planning permission for private houses, and 75m² for all other types of buildings except apartments.

Post Installation Solar PV Maintenance

Solar panel maintenance costs are typically low, as they just need to be kept clean. Rain can clear dust and debris away, but you should carry out an annual clean to make sure they are working to their full potential.

This is a relatively simple job – and unlike installing the panels – you can do it ‘DIY’ if you wish to. All you need is biodegradable soap and a bucket of water with a a soft cloth or sponge. Just ensure to be gentle and use products and materials that will not scratch the panels.

Your solar panels should also be inspected every five years or so by an expert to ensure that everything is in working order, ensuring maximum efficiency.


Yes, in 2024, the SEAI provides up to €2,100 for homeowners to install solar panels. The amount of grant funding is ties to the size of the size of the solar PV system being installed. In order to get the SEAI grant, you must choose from their list of registered Irish solar installers.

If you don’t want the added expense of installing a battery storage system, there is also the option of selling surplus electricity generated by your solar panels back to the national grid.

Solar PV systems typically have an estimated lifespan of 25-30 years, with the majority covered under warranty for a period of 25 years. They will not suddenly stop working after this period, but will lose their efficiency over time.

Yes, while some people might think the Irish climate is not suited for solar energy, the solar output here is more than sufficient to see electricity generated year round. With high electricity prices and falling costs of solar technology, solar panels can pay themselves off in as little as 5 or 6 years.
