Solar panels in Roscommon: key benefits

Save on Electricity Bills

A 4kWp solar system in Roscommon generates approximately 3,468 kWh per year, covering 83% of average household use and saving an estimated €1040+ annually.

SEAI Grant: Up to €1,800

Get up to €1,800 back from SEAI for your solar installation. The grant is available for homes built and occupied before 2021. No means testing; it’s property-based.

0% VAT Saves ~€1,000

Since May 2023, residential solar panel installations are zero-rated for VAT. This saves approximately €1,000 on a typical installation compared to the old 13.5% rate.

Earn from Excess Energy

Sell surplus electricity back to the grid at 15-25c/kWh through Ireland’s Microgeneration Support Scheme. The first €400/year of export income is tax-free.

Increase Property Value

Solar panels improve your BER rating and can increase your property value by up to 4%. Buyers increasingly look for energy-efficient homes with lower running costs.

25+ Year Lifespan

Modern solar panels last 25-30 years with minimal maintenance. In Roscommon, a typical system pays for itself in 4-6 years, leaving 20+ years of near-free electricity.

Strong Year-Round Performance

While Roscommon may see more cloud cover, solar panels still perform well here. Longer summer days at this northern latitude boost generation, and cooler temperatures improve panel efficiency.

How much electricity will solar panels generate in Roscommon?

Roscommon receives approximately 1,200 sunshine hours per year, ranking #19 out of 26 counties for solar potential. A standard 4kWp system generates around 3,468 kWh annually, covering 83% of average household electricity consumption (4,200 kWh/year).

Are solar panels worth it in Roscommon?

Yes. At 867 kWh per kWp, solar panels in Roscommon generate significant returns. With the €1,800 SEAI grant, 0% VAT, and electricity savings of approximately €1040+ per year plus export income, a typical system pays for itself in 4-6 years and lasts 25+ years.

Does Roscommon get enough sun for solar panels?

Ireland receives enough solar radiation for panels to work effectively year-round. Roscommon gets around 1,200 sunshine hours per year with approximately 1,093mm of annual rainfall. Solar panels also generate electricity on cloudy days, just at reduced output. Germany, which has similar sunshine levels to Ireland, is one of the world’s largest solar markets.

How long does solar panel installation take?

Most residential installations are completed in 1-2 days. The full process (from SEAI grant application to completed installation) typically takes 4-8 weeks. You must receive your SEAI Letter of Offer before any work begins.

Do I need planning permission for solar panels?

Most residential installations are exempt from planning permission, provided panels don’t project more than 15cm from the roof surface and don’t cover more than 50% of total roof area. Listed buildings and conservation areas may require permission.

Can I sell excess electricity back to the grid?

Yes. Under Ireland’s Microgeneration Support Scheme, you sell surplus electricity at 15-25c per kWh depending on your supplier. You need a smart meter (ESB Networks installs these for free). The first €400/year of export income is tax-free.

How do I apply for the SEAI solar grant in Roscommon?

Apply online at seai.ie. You need an SEAI-registered installer, your MPRN (from your electricity bill), and your Eircode. Do not start work before receiving your Letter of Offer. After installation, a BER assessment is required. The grant is paid directly to your bank account within 4-6 weeks.

What does solar panel installation involve in Roscommon?

Solar panel installation in Roscommon typically takes 1–2 days for a standard 4kWp residential system. An SEAI-registered installer will survey your roof, install mounting rails, fit 10–12 panels, wire in a hybrid inverter, and connect to your meter. A post-installation BER assessment is required to release the SEAI grant. Most homes in Roscommon don’t need planning permission.

What is the total cost of solar panels in Roscommon after the SEAI grant?

The total cost of a 4kWp solar panel system in Roscommon is typically €5,000–€8,000 before grants. After the €1,800 SEAI grant (and with 0% VAT already applied), the net cost is €3,200–€6,200. This includes panels, inverter, mounting, wiring, and BER assessment. At 867 kWh/kWp in Roscommon, the system pays for itself in 4–6 years.

Which Roscommon towns get the most solar energy?

Solar yield varies by location within Roscommon. These rankings are based on PVGIS data for each town, showing estimated output from a typical 4kWp system.

RankTownSolar Yield (kWh/kWp)Est. Annual Output (4kWp)
1Ballinasloe7773,108 kWh

Solar Panel Guide for Roscommon

Roscommon's central position avoids coastal extremes

Roscommon is one of Ireland's many landlocked counties, with no coastline at all. This inland position means it avoids the salt spray and extreme wind loading that affects coastal installations. Properties across Roscommon, from Boyle in the north to Ballinasloe's hinterland in the south, enjoy relatively calm conditions for panel mounting. The county's 1,093mm annual rainfall is moderate, and frontal systems lose some intensity by the time they reach Roscommon from the Atlantic.

Roscommon's dispersed rural population and one-off houses

Roscommon has one of the most dispersed populations in Ireland, with a high proportion of one-off rural houses and bungalows. These properties are typically detached with large, unshaded roofs and generous gardens, making them ideal for both roof-mounted and ground-mounted solar systems. The lack of neighbouring buildings means shading is rarely an issue. Many of these rural homes were built in the 1970s-1990s with large south-facing roof areas that can accommodate 4-6kWp systems comfortably.

Livestock farming dominates and solar can offset costs

Roscommon's agriculture is predominantly beef and sheep farming on grassland. While these farms have lower electricity demands than dairy or tillage operations, they still benefit from solar on shed roofs for lighting, water pumping, and electric fencing. The growing use of meal feeders, automatic scrapers, and water heating for calf rearing has increased farm electricity consumption. TAMS III makes solar accessible for Roscommon farmers, with typical 10-15kWp systems providing a meaningful reduction in annual electricity bills.

Athlone's influence extends into south Roscommon

Athlone, though primarily in Westmeath, has significant residential overflow into south Roscommon around Monksland, Kiltoom, and Knockcroghery. This growth area has modern housing estates with good solar potential, and residents benefit from Athlone's installer market rather than relying on more remote Roscommon-based services. The M6 motorway connection means Dublin and Galway-based installers also serve this area at competitive rates, giving south Roscommon homeowners better access to quotes than the county's more isolated northern areas.
