Solar Energy in Ireland
Harnessing the power of the sun in the Emerald Isle
Ireland's Solar Potential
Despite Ireland's reputation for rain and cloudy skies, the country receives sufficient solar radiation to make solar photovoltaic (PV) systems a viable and increasingly popular renewable energy option. Ireland receives approximately 950-1,100 kilowatt hours per square meter annually, which is comparable to many regions in Germany and France where solar energy is already well-established.
Solar PV panels work efficiently even on cloudy days, capturing diffused sunlight to generate clean electricity. With improving technology and decreasing costs, combined with generous government support schemes, there has never been a better time for Irish homeowners and businesses to invest in solar energy.

Solar Grants & Support in Ireland
Financial support to make solar energy more accessible
SEAI Solar PV Grant Scheme
The Sustainable Energy Authority of Ireland (SEAI) offers generous grants for homeowners installing solar PV systems:
- Up to €2,400 for residential installations
- €900 for 2kWp systems
- €1,800 for 4kWp systems
- Additional €300 per kWp after 4kWp
- Battery storage grant also available
Microgeneration Clean Export Guarantee (MCEG)
Sell your excess solar electricity back to the grid and earn additional income:
- Earn payments for surplus electricity
- Competitive rates from electricity suppliers
- Automatic export measurement
- Systems up to 6kW eligible
- Simple registration process
Planning Permission & Requirements
In most cases, solar PV installations in Ireland are considered exempt development and do not require planning permission, provided they meet certain conditions:
Generally Exempt:
- Roof-mounted panels on pitched roofs
- Panels that don't exceed roof height by more than 50cm
- Systems not visible from the public road
- Installations on non-protected structures
May Require Permission:
- Protected structures or conservation areas
- Ground-mounted systems over certain size
- Flat roof installations visible from street
- Listed or historic buildings

Understanding the Numbers
Rapid Growth
Ireland has seen a dramatic increase in solar PV installations, driven by improved technology, falling costs, and generous government grants. The sector is experiencing unprecedented growth as more Irish households recognize the financial and environmental benefits.
Energy Independence
A typical 4kWp solar system in Ireland can generate approximately 3,200-3,600 kWh annually, covering 30-50% of an average household's electricity needs. When combined with battery storage, this percentage can increase to 60-70%, providing greater energy independence.
Financial Returns
With SEAI grants reducing upfront costs and the MCEG scheme providing payments for exported electricity, solar systems in Ireland typically pay for themselves in 8-12 years. After this period, you continue to benefit from free electricity for the remaining 15+ years of system life.
Environmental Impact
Every 4kWp solar system installed prevents approximately 1.5 tonnes of CO₂ emissions annually – equivalent to planting 70 trees each year. By choosing solar, Irish homeowners are making a significant contribution to Ireland's climate action goals and creating a cleaner future.
