Planning Permission for Solar Panels in Ireland

Do You Need Planning Permission to Install Solar Panels?

If you're considering installing solar panels in Ireland, one of the first questions you might ask is whether you need planning permission. The good news is: in most cases, no planning permission is required. Thanks to revised exemptions introduced in October 2022, homeowners across Ireland can install solar panels on their rooftops without needing to seek formal planning approval, making it easier than ever to go solar.

But like all things related to home improvement and energy, there are a few exceptions and important guidelines to be aware of. In this guide, we'll break down what the current planning rules say, where exemptions apply, and what to consider before installing solar panels on your home in Dublin, Cork, or anywhere else in Ireland.

The 2022 Planning Exemption: What Changed?

In October 2022, the Irish government removed the requirement for planning permission for the vast majority of domestic solar panel installations. This move supports Ireland’s Climate Action Plan, aiming to increase renewable energy usage and reduce reliance on fossil fuels.

Key points of the exemption include:

• No planning permission is required for rooftop solar panels on houses, regardless of roof size.
• This applies to homes in both urban and rural areas.
• The exemption includes apartment buildings and industrial and agricultural buildings in most cases.
• It enables homeowners to make the switch to solar energy faster and with fewer administrative delays.

Are There Any Exceptions?

Yes, there are a few scenarios where planning permission may still be required:

1. Protected Structures or Heritage Sites

If your home is a listed building or lies within an Architectural Conservation Area (ACA), you may need to apply for planning permission. This is to protect the visual character and historical significance of these areas.

2. Flat Roof Installations

While roof-mounted systems on pitched roofs are typically exempt, flat roof solar installations that require tilt frames or mounting structures over a certain height may need planning review. Especially if they affect neighbours or the building’s appearance significantly.

3. Non-Rooftop Installations

If you plan to install ground-mounted solar arrays in your garden or elsewhere on your property, you may face limitations based on size, location, and visibility. In some cases, these will still require planning permission depending on local regulations.

Other Regulations to Be Aware Of

Even though planning permission may not be needed, it’s essential to follow certain technical and legal guidelines, including:

• Maximum panel height above the roof surface must not exceed 300mm.
• Panels should not interfere with building services, such as chimneys or roof ventilation.
• Installations must be carried out by certified electricians and comply with SEAI (Sustainable Energy Authority of Ireland) and ESB Networks requirements.
• Ensure you register your installation with ESB Networks before turning it on.

Apartment Buildings and Multi-Unit Developments

The 2022 regulations also opened the door for apartment blocks and multi-unit developments to install solar systems without planning. However, these installations must still meet criteria regarding the visual impact and roof coverage. In practice, this means owners' management companies (OMCs) and resident groups may need to coordinate the installation process and ensure structural suitability.

SEAI Grant Considerations

While planning permission may not be required, you’ll still want to ensure your system is eligible for the SEAI Solar Electricity Grant.

To qualify:

• Your installer must be SEAI-registered.
• You must have a Building Energy Rating (BER) assessment after the installation.
• Your home must be built and occupied before 2021.
