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.
