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.

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 Louth?

Solar panel installation in Louth 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.

Solar Panel Guide for Louth

Louth's east coast position delivers above-average sunshine

Louth sits on Ireland's east coast, sheltered from Atlantic weather by the rest of the island. This gives Louth relatively low rainfall of 875mm and around 1,315 sunshine hours annually. The coastal strip from Dundalk to Drogheda benefits most, with the Cooley Peninsula and Carlingford Lough area slightly wetter due to the Cooley Mountains. Overall, Louth's climate is more suited to solar than its northerly latitude might suggest, and it consistently outperforms inland counties at similar latitudes.

Dundalk and Drogheda commuter belt drives strong demand

Louth's two main towns are major Dublin commuter hubs, with large housing estates built during the Celtic Tiger era. Estates in Dundalk (Blackrock, Haggardstown, Mount Avenue) and Drogheda (Bryanstown, Moneymore, Rathmullen) feature modern housing with standard pitched roofs ideal for solar. These commuter households typically have high electricity bills from EVs, home offices, and family usage. The combination of good solar conditions and high consumption makes payback periods in Louth among the shortest in the northeast.

Cross-border proximity brings competitive installer options

Louth borders County Armagh, and its position on the Dublin-Belfast corridor means it is served by installers from both directions. Dublin-based companies treat Louth as part of their extended service area, while Northern Ireland installers based in Newry and Armagh also quote for Louth jobs. This cross-border competition gives Louth homeowners more choice and typically more competitive pricing than counties at a similar distance from Dublin but without the NI border advantage.

Louth's strong per-capita solar adoption rate

With 1,084 SEAI installations in 2025 and a population of around 140,000, Louth has one of the highest per-capita solar adoption rates outside of Dublin. The county's compact size, good road network, and proximity to Dublin all contribute to this. Louth County Council has also been proactive in promoting energy upgrades through its local authority energy efficiency programmes, and the visible presence of solar panels on neighbouring homes has created a strong word-of-mouth effect in residential estates.
