Your solar questions for Milltown
How much do solar panels cost in Milltown?

What is the difference between solar PV and solar thermal?

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.

A typical residential installation takes 1-2 days. This includes scaffolding, mounting the panels, wiring, inverter installation, and connecting to the grid. Your installer handles the ESB Networks notification (NC6 form).
