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 Waterford?
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.
