How Cork is going solar
3,603 Cork homes installed grant-supported solar in 2025
2nd of 26 counties for solar installations in 2025
4,106 kWh Typical annual output of a 4.2 kWp system in Cork
161 SEAI-registered installers serving the county (22 local specialists)
3,603 households in Cork completed a grant-supported solar installation in 2025 under the SEAI Solar PV Scheme — well above the national county average, and the 2nd highest count in the country out of 33,049 installations nationwide. Every one of those systems was fitted by an SEAI-registered installer like the ones listed above.
Our model estimates that a typical 10-panel (4.7 kWp) south-facing system in Cork generates around 4,574 kWh a year, with a modelled generation range of 4,117–5,032 kWh. The county adjustment is based on PVGIS output, where Cork ranks 3rd of the 26 counties. That produces a modelled savings range of €778–€1,449 a year across different yield, tariff and self-consumption assumptions, with central savings of €1,110 a year and simple payback on first-year savings of 5.3 years. Battery storage, panel count and your roof's orientation all shift that number — which is exactly what a good installer quote pins down.
Sources: Solar Info, State of Solar in Ireland 2025 (reporting SEAI Solar PV Scheme county volumes); PVGIS v5.2 (EU Joint Research Centre) output model. EnergyBase model uses the Cork PVGIS yield adjustment (1.081×), 35% central self-consumption without a battery, import at €0.35/kWh and export at €0.185/kWh. Savings range varies yield, tariffs and self-consumption assumptions.

Solar in Cork
Cork solar questions, answered
What homeowners in Cork ask before going solar.
How much do solar panels cost in Cork?
Our estimate model puts a typical 10-panel (4.7 kWp) system at €7,650 before the €1,800 SEAI grant, or €5,850 after it. The displayed estimate range is €4,800–€6,900. Prices in Cork follow the same model — your roof, system size and whether you add a battery can change the result. Comparing at least 3 quotes is the reliable way to find out what your home costs.
How many solar installers work in Cork?
161 SEAI-registered solar installers currently serve Cork, including 22 local specialists focused on the county and its neighbours. All of them are listed (and filterable) on this page.
Do I need planning permission for solar panels in Cork?
In almost all cases, no. Since 2022, rooftop solar on houses is exempt from planning permission across Ireland, with limited exceptions near protected structures and in some solar safeguarding zones. Your installer confirms this during the site survey.
Is the SEAI grant available in Cork?
Yes — the SEAI Solar Electricity Grant (up to €1,800) is available nationwide, including Cork, for homes built and occupied before 2021. Your installer typically handles the paperwork.
How do I choose between installers in Cork?
Look for an SEAI registration (everyone on this page has one), strong recent Google reviews, a few years of trading history, and a detailed written quote. We've written a full guide on choosing a solar installer — and getting multiple quotes is the single best protection.
