Value of Electricity Generated ?Households, businesses, and other organisations save money on their electricity bills by having solar panels installed. On top of this, they can also earn money by selling surplus electricity from their solar panels to the grid. Here's the approximate combined value of those savings and export payments over recent months and years. The benefits vary substantially between seasons.

ESBN-Confirmed Quarterly Micro/Mini Generation Additions ?New connections confirmed each quarter by ESB Networks, in two size bands: up to 6 kW ('Micro-Generation', mostly homes) and 6–50 kW ('Mini-Generation', mostly farms and businesses). The vast majority in both bands are expected to be solar PV. Only complete, confirmed quarters are shown; no estimates or projections.

Systems Installed Capacity Installed (MW)

ESB Networks figures include all grid-connected systems (including non-grant and commercial installations). For official SEAI residential grant completion statistics, see Solar PV Grant Statistics.

Growth Trend

The table below shows projected cumulative totals at each year-end. The extrapolation is based on the installation rate over the most recent four quarters with available data, projected forward at a constant rate.

Solar Energy Forecast ?The forecast refers to the available solar energy in the selected area (on a "horizontal plane"). Electricity production also depends on the number, size, efficiency, and orientation of your solar panels.

About

General

'Small-scale solar' on this page means smaller solar PV systems (up to 50 kW) installed on homes, farms and businesses. This corresponds to the 'Micro-Generation' (up to 6 kW) and 'Mini-Generation' (6–50 kW) categories in ESB Networks' connection statistics. Not to be confused with the ESB Networks phrase "Small-Scale Generation" which refers to systems between 50 kW and 200 kW in size.

Larger systems like big commercial rooftops and solar farms are not included. ESB Networks' 'Non-Export' category is also excluded.

This dashboard gives estimates about such systems in Ireland (26 counties only).

Data Accuracy

The data shown on this dashboard are estimates and may change as we periodically update data and refine our calculations.

Current Data Sources

Number and capacity of systems installed (from 1^st October 2024): ESB Networks generator statistics (Micro- and Mini-Generation categories)

Breakdown by county: SEAI retrofit reports (analyzed in detail in our Solar PV Retrofit Tracker)

Solar radiation forecasts (also used for today's live production estimates): Open Meteo (CC BY 4.0)

Solar radiation data (historical monthly totals): Met Éireann

Electricity prices for households: CSO

Solar PV capacity in Ireland pre-2019 (29MW): Energy Ireland

Household solar PV system sizes: National BER Research Tool

Current Key Assumptions and Simplifications

Trend in installation sizes extrapolated from BER Assessment data, and then scaled according to ESB Networks data

All panels modeled as horizontal (this is a reasonable approximation for a mixture containing a variety of orientations)

Solar panel productivity assumed to be equal across counties (simplification)

Installation numbers are extrapolated forward based on the latest known installation rate

Installation numbers are assumed to be spread equally across days in each quarterly period

The proportion of installations which are grant-aided is assumed to be the same for all dates prior to 1^st October 2024

County-level system and savings figures are estimated by distributing national ESB Networks totals according to each county's share of SEAI solar PV grant completions, normalized by CSO Census 2022 occupied private households

Radiation forecasts timepoints are hourly on the hour. We use linear interpolation for estimates between these times

Electricity value based on the rates paid by large household consumers from CSO data. For years without CSO data available, we estimated these using linear regression with the previous year's wholesale electricity prices as the predictor variable (values with a * in the table below)
