As the push for renewable energy continues to grow, more and more homeowners in Ireland are turning to solar power to generate electricity. A 5kW solar panel system, in particular, is a popular choice as it is capable of producing 5,000 watts of electricity, enough to meet the energy needs of an average-sized home.

In this article, we will take a closer look at the price of a 5kW solar panel system in Ireland, including factors that can affect the price, government incentives, and the benefits of choosing this type of system.

What is a 5kW Solar System?

A 5kW solar system is an array of photovoltaic (PV) panels that generate electricity from sunlight. The size of the array depends on the amount of electricity needed and the available space for installation. A typical residential 5kW solar system consists of 20-25 PV panels and can produce up to 6,000 kWh per year.

How Much Does a 5kW Solar System Cost in Ireland?

The cost of a 5kW solar system in Ireland varies depending on several factors, such as location, type of panels used, and installation costs. Generally speaking, a typical residential 5kW solar system can cost between €10,000 – €13,000 before any grants or incentives are applied. Here are several factors that affect the cost of a 5kW solar system in Ireland:


The location where you plan to install your solar system will impact its price. For example, if you live in an area with high levels of sunlight, you may get away with fewer PV panels, which would reduce your overall costs. On the other hand, if you live in less sunlight, you may need more PV panels, which would increase your expenses.

Type Of Panels Used

PV panels have different efficiency ratings, producing different amounts of energy per square meter. This affects their overall cost as well as their performance over time. It’s essential to research various types of PV panels before deciding which ones to use for your project.

Installation Costs

Installation costs vary depending on who is doing the work and how complex it is. It’s essential to shop around for quotes from different installers before deciding who will do the work for you.

Roof size and orientation

The size of the roof and the direction of the solar panels will also impact the overall cost. A larger roof will require more solar panels, and a south-facing orientation will generally be more efficient.

Government Incentives

The Irish government offers a range of incentives for homeowners who install solar panel systems. The SEAI Better Energy Homes Scheme provides a grant of €2,100 for residential and commercial properties towards the cost of the system. Additionally, the Renewable Energy Feed-in Tariff (REFiT) scheme pays homeowners for any excess electricity their system generates. The TAMS II grant can cover up to 60% of the overall cost. These incentives can significantly reduce the price of a solar panel system and make it more affordable for homeowners.

Tips For Saving Money When Installing A Solar System In Ireland

If you’re looking to save money when installing a solar system in Ireland, there are several things that you can do:

Take Advantage Of Grants And Incentives

Several grants and incentives are available for homeowners who want to install a solar system in Ireland, such as SEAI grants and tax reliefs, which can help significantly reduce your overall costs. It’s essential to research these options thoroughly before deciding which ones are best for your situation.

Shop Around For Quotes

As mentioned above, installation costs vary depending on who is doing the work, so it’s essential to shop around for quotes from different installers before deciding who will do the job for you. This will help ensure you get the best deal possible on your installation costs.

Choose High-Quality Panels

Although higher quality PV panels may be more expensive upfront, they tend to last longer and perform better over time, so it’s worth investing in them as this could save money long-term by reducing maintenance costs and increasing energy production efficiency.

How Much Energy Does A 5Kw Solar Panel System Produce?

The energy produced by a typical residential 5Kw solar panel system is approximately 6,000 kWh per year (depending on environmental conditions). This amount could provide enough power for most homes without requiring additional sources such as gas or electricity from grid supplies. As such, it can help significantly reduce monthly electricity bills and even lead to savings or income through Feed-In Tariffs (FITs).

Benefits of Choosing a 5kW Solar Panel System

Cost savings

The system can save homeowners money on their electricity bills. This can be especially beneficial for those who live in areas with high electricity costs.

Low maintenance

Once installed, PV panel systems require very little maintenance. This makes them a cost-effective and hassle-free energy source.

Environmental impact

Solar energy is a sustainable and clean energy source that does not produce any emissions. Choosing a solar panel system can positively impact the environment and help reduce dependence on fossil fuels.

Increase in property value

Having a PV panel system installed can increase the value of your property, making it more attractive to potential buyers.
