Dáil Éireann Debate, Thursday - 25 June 2026
220. Deputy Malcolm Byrne asked the Minister for Climate, Energy and the Environment to outline Government policy toward plug-in solar panels; the supports available; and if he will make a statement on the matter. [48622/26]
View answerPlug-in solar systems are very small PV energy systems, usually two or three modules and less than 1 kW in total per installation, which are connected to a micro-inverter and plugged directly into a normal household socket. This then feeds the house’s internal electricity system. These low-cost panels can be put on balconies or outdoor spaces. The use of plug-in mini solar technology has grown in some EU countries in recent years as consumers search for ways to save on high energy bills.
As Minister, I am supportive of any technology which can reduce costs for households and consumers and increase the share of renewables on our system, provided that it can be integrated safely. For that reason, last month I wrote to ESB Networks (ESBN) requesting that, in its capacity as the body responsible for safety regulations and technical standards for the distribution grid, it works with the National Standards Authority of Ireland, Safe Electric and the Commission for Regulation of Utilities to prioritise and accelerate the development of standards that will permit the use of "plug-in" solar systems in Ireland.
The Managing Director of ESBN has since written to me confirming ESBN's support for the safe, proportionate use of small, plug-in solar or battery devices up to a total of 800W (AC) provided that the following conditions are met:
• customer and public safety are prioritised and assured;
• network integrity and power quality are maintained in all operating conditions;
• the DSO has appropriate visibility of connected generation through a simple registration process; and
• devices meet the relevant technical and product standards.
ESBN has commenced work in this regard and has written to other key stakeholders with a view to coordinating the respective positions and set out a shared pathway to accelerate the deployment of plug-in solar and storage. Engagement with Eirgrid to ensure that it is adequately prepared for the impact of plug-in generation on the transmission network will also take place.
ESBN is also engaging with the UK-based Electricity Networks Association to align approaches with the evolving UK position on plug-in generation and storage to ensure a consistent approach across Northern Ireland and Ireland, reflecting the cross-border market for devices, installers and network participation. My officials are also in contact with officials from the Department for Energy Security and Net Zero in the UK. EU Guidance on the matter is also being considered.
