A Review of Policies for the Rollout of Rooftop Solar PV in Ireland

This report surveys potential policy measures to support sustainable growth in solar PV that have recently been implemented or proposed in other jurisdictions. These measures can be assessed to determine their relevance to Ireland. In Section 2 we review the solar market from a global perspective with a focus on uptake rates, costs and supply chains. Section 3 examines barriers to adoption and specific policy support measures used internationally to support solar PV. In Section 4 we review barriers to adoption in Ireland and the current policy environment. It also provides quantitative modelling results for rooftop solar PV and battery storage adoption by Irish households that illustrate how policy and cost developments influence installed capacities. In Section 5, some specific areas for further solar PV policy development in Ireland are identified. Based on these findings, it is concluded that the combined potential for deployment of small-scale solar PV in residential and non-residential settings may be greater than currently assessed.
