The Best Locations for Installing Solar Panels in Ireland

Solar panels have become an increasingly popular choice for renewable energy in Ireland. With the country's commitment to reducing carbon emissions and transitioning to a more sustainable future, many homeowners and businesses are turning to solar panels as a way to generate clean and affordable electricity. But when it comes to installing solar panels in Ireland, one of the most common questions is: what is the best location?

The Importance of Location for Solar Panels

Before we dive into the best locations for solar panels in Ireland, it's important to understand why location matters in the first place. Solar panels work by converting sunlight into electricity through photovoltaic cells. This means that the amount of sunlight a panel receives directly affects its efficiency and output. Therefore, the location of your solar panels plays a crucial role in how much energy they can produce. In general, solar panels perform best when they are installed in areas with high levels of sunlight and minimal shading.

This is why choosing the right location for your solar panels is essential for maximizing their potential.

The Best Locations for Solar Panels in Ireland

When it comes to installing solar panels in Ireland, there are a few key factors to consider: sunlight, shading, and orientation.


Ireland may not be known for its sunny weather, but that doesn't mean it's not a suitable location for solar panels. In fact, Ireland receives an average of 3.5 hours of sunlight per day, which is enough to make solar panels a viable option. However, some areas of the country receive more sunlight than others. The southeast region of Ireland tends to have the highest levels of sunlight, making it an ideal location for solar panels. Counties like Wexford, Waterford, and Kilkenny are known to have the most sunshine hours in the country. On the other hand, the northwest region of Ireland tends to have lower levels of sunlight, making it less suitable for solar panels.

Counties like Donegal, Sligo, and Mayo receive the least amount of sunlight in the country.


As mentioned earlier, shading can significantly impact the performance of solar panels. This is because even a small amount of shading can reduce the amount of sunlight that reaches the panels, resulting in lower energy production. When choosing a location for your solar panels, it's essential to consider any potential sources of shading. This could include nearby buildings, trees, or even chimneys. It's best to avoid installing solar panels in areas that are heavily shaded throughout the day.


The orientation of your solar panels also plays a crucial role in their performance.

In Ireland, solar panels should ideally be facing south to maximize their exposure to sunlight. This allows them to capture the most amount of sunlight throughout the day. If south-facing installation is not possible, east or west-facing panels can still be effective. However, they may produce slightly less energy compared to south-facing panels.

Other Considerations for Solar Panel Installation

In addition to location, there are a few other factors to consider when installing solar panels in Ireland.

Roof Type

The type of roof you have can also impact the installation of solar panels. In general, pitched roofs are more suitable for solar panel installation compared to flat roofs.

This is because pitched roofs allow for better panel orientation and less shading from nearby structures.

Roof Condition

Before installing solar panels, it's important to ensure that your roof is in good condition. Solar panels typically have a lifespan of 25-30 years, so you want to make sure your roof can support them for that long. If your roof needs repairs or replacement, it's best to address those issues before installing solar panels.

Planning Permission

In most cases, you will not need planning permission to install solar panels in Ireland. However, if your property is a listed building or located in a conservation area, you may need to seek permission before installation.

The Bottom Line

When it comes to the best locations for installing solar panels in Ireland, the southeast region tends to be the most suitable due to its higher levels of sunlight.

However, with proper planning and consideration of factors like shading and orientation, solar panels can be installed in various locations throughout the country. Ultimately, the best location for your solar panels will depend on your specific property and its surroundings. It's always best to consult with a professional solar panel installer who can assess your property and recommend the most suitable location for optimal energy production.
