Ready to understand? Let's get started!

Factors Affecting Solar Panel Costs

The size and type of solar panels, along with the type of home (house, apartment, etc.) and location, are key factors that can impact the cost of solar panel installation in Ireland.

Size and type of solar panels

Big or small solar panels change the cost. If you need lots of power, you will need big panels. They take up more space but give more energy. Small ones are good if you have less space.

Yet, they might not have enough power for your house. There are different types of panels, too. Some work best in bright sunlight; others do well even on cloudy days. The type of panel changes how much it costs as well.

Decide what is most important to you—size, type, or both? This step helps cut down the prices you see from €6,000 to €18,000 to a handy range that fits your pocket and needs.

Type of home (house, apartment, etc.)

Houses, apartments, and other types of homes can all benefit from solar panel installation in Ireland. Whether you live in a large, four-bedroom house or a cosy apartment, solar panels can help you save money on your energy bills and reduce your carbon footprint.

The cost of installing solar panels will depend on the size and type of system you choose, but there are grants available to help offset these expenses. So no matter what type of home you have, consider the benefits of solar power for a more sustainable and cost-effective energy solution.

Location and installation costs

Installing solar panels in Ireland involves both location and installation costs. The location of your home plays a role in determining the amount of sunlight it receives, which directly impacts the efficiency of your solar panels.

Installing solar panels on a roof that gets ample sunlight can maximise their effectiveness. As for installation costs, these vary depending on factors such as the size and type of solar panels you choose, as well as any additional equipment or labour required for installation.

It's important to consider these factors when budgeting for your solar panel project to ensure you have a clear understanding of the total cost involved.

Available Grants for Solar Panel Installation

In Ireland, homeowners can take advantage of various grants to help offset the cost of solar panel installation. There are specific grants available for both solar electricity (PV) and solar water heating (thermal) systems, making it easier for individuals to switch to renewable energy sources.

These grants play a crucial role in encouraging more people to adopt clean and sustainable energy practises.

Solar Electricity/Solar PV Grants

If you're interested in installing solar panels on your home in Ireland, there are grants available to help with the cost. Solar Electricity/Solar PV Grants can provide financial assistance towards the installation of a photovoltaic (PV) system.

These grants aim to encourage homeowners to choose clean and renewable energy sources for their electricity needs. By taking advantage of these grants, you can reduce the upfront cost of installing solar panels and make sustainable energy more accessible for your household.

Solar Water Heating/Solar Thermal Grants

Solar water heating grants are available in Ireland to help homeowners offset the cost of installing solar thermal systems. These grants aim to encourage the use of renewable energy and reduce reliance on fossil fuels for water heating.

By installing a solar water heating system, homeowners can save money on their energy bills while also reducing their carbon footprint.

The cost of installing a solar thermal system can vary depending on factors such as the size of the system and the type of panels used, but these grants provide financial assistance that makes it more affordable for homeowners.

With these grants, Irish homeowners have the opportunity to embrace sustainable energy and contribute to a greener future.

Installing a solar thermal system not only saves money but also reduces greenhouse gas emissions by using clean, renewable power to heat water. It's an investment that pays off in both financial savings and environmental benefits.

Calculating the Cost and Returns of Solar Panels

To calculate the cost and returns of solar panels, factors such as the payback period, electricity generated, and carbon footprint reduction should be taken into account.

Payback period

The payback period is an important factor to consider when deciding to install solar panels in Ireland. The payback period refers to the amount of time it takes for the cost of the installation to be recouped through energy savings.

On average, the payback period for solar panel installations in Ireland ranges from 7 to 10 years. This means that after this initial period, any electricity generated by your solar panels will essentially be free, leading to significant savings on your energy bills.

Considering the long-term benefits and potential savings, investing in solar panels can be a smart choice for homeowners looking to reduce their carbon footprint and save money on their energy costs over time.

Electricity generated

Solar panels generate electricity by converting sunlight into usable energy. The amount of electricity generated depends on factors such as the size and efficiency of the solar panels, as well as the amount of sunlight your location receives.

On average, a 5kW solar system in Ireland can generate around 4,800 to 6,000 kilowatt-hours (kWh) per year. This means that homeowners can significantly reduce their reliance on traditional grid electricity and potentially save money on their energy bills.

Additionally, using solar power helps reduce carbon emissions and contributes to a greener, more sustainable future for Ireland. With the available grants for solar panel installation in Ireland, it becomes even more viable to invest in this clean source of renewable energy.

Carbon footprint reduction

We all want to do our part in protecting the environment, and one way to make a difference is by reducing our carbon footprint. Solar panels can help with this, as they produce clean and renewable energy.

By installing solar panels on your home in Ireland, you can significantly reduce your carbon footprint. This is because solar panels use sunlight to generate electricity, which means less reliance on fossil fuels that contribute to greenhouse gas emissions.

In fact, a 5 kW solar system installed in Ireland can save approximately 2 tons of CO2 emissions per year. So not only will you be saving money on your energy bills, but you'll also be taking an important step towards a more sustainable future for our planet.


The cost of installing solar panels in Ireland can vary depending on factors such as the size and type of panels, the type of home, and location. However, there are available grants to help offset these costs.

Solar panels have the potential to save homeowners money on their energy bills and contribute to a cleaner environment. Also, with solar panel installation prices predicted to decrease in the future, it is becoming an increasingly viable option for Irish homeowners looking to invest in renewable energy.
