Generating electricity from solar

The term ‘solar panel’ is often used interchangeably to describe the panels that generate electricity and those that generate hot water.


  • Solar panels that produce hot water are known as solar thermal collectors or solar hot water collectors.
  • Solar panels that produce electricity are known as solar photovoltaic (PV) modules. These panels generate DC electricity when exposed to light.

    • New rebate for Solar PV

    We are delighted to offer homeowners a rebate to support the installation of Solar PV panels and battery energy storage systems.


  • This will reduce the electricity you currently purchase from your supplier and save you money. Support is available to all owners of dwellings built and occupied before 2011
  • and where SEAI have not previously provided support for solar PV system at that address. This is available for all new Solar PV installations from Tuesday 31st July 2018.

    • Installation of domestic solar PV system

    A domestic solar PV system consists of a number of solar panels mounted to your roof (or in your garden) and connected into the electrical loads within your building.


  • The solar panels generate DC (direct current – like a battery) electricity, which is then converted in an inverter to AC (alternating current – like the electricity in your domestic socket).
  • Solar PV systems are rated in kilowatts (kW). A 1kW solar PV system would require 3 or 4 solar panels on your roof.
