Do I need a smart meter for solar panels?

How does shading affect solar panels in Dublin 18?
Shading from trees, chimneys, or nearby buildings can reduce output significantly. Modern systems use optimisers or microinverters so that shading on one panel doesn't drag down the whole system. Your installer will assess shading during the site survey.
Do I need planning permission for solar panels?
Most residential solar installations are exempt from planning permission, provided panels don't project more than 15cm from the roof and don't cover more than 50% of total roof area.
Do solar panels increase property value in Dublin 18?
Yes. Solar panels improve your BER rating and can increase property value by up to 4%. Buyers increasingly look for energy-efficient homes with lower running costs. A solar system in Dublin 18 is a long-term investment in your property.
