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 Leitrim?
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.
