The Microgeneration Support Scheme (MSS) was approved by Government on 21 December 2021, to support Ireland’s ambitious targets for micro-generation installations, under the Climate Action Plan. The MSS provides supports to both domestic and non-domestic applicants, in the form of grants for Solar PV installations, up to a maximum of €1,800 in 2025 for household installations. These grants are available through the Sustainable Energy Authority of Ireland (SEAI).
The SEAI maintains data regarding the financing and functioning of the Domestic Solar PV scheme and has facilitated the information in response to your question.
See below a breakdown of the average cost to install solar PV that led to an energy uplift of BER B2 or higher for 2020 to date.
It should be noted that these costs represent the value of Solar PV systems only as entered by Solar PV installers during the grant application process and are excluding the grant. Furthermore, the achievement of a BER rating of B2 or higher, following the installation of Solar PV, will depend on the BER rating of the home prior to the installation of a Solar PV system. The cost below do not take account of the cost of the other energy improvement in the home that may have an impact on the BER rating prior to the installation.
