Solar Energy Savings in Leinster

How Solar Reduces Your Electricity Bills

The calculations below show how your electricity bills change with solar.

What drives your savings in Leinster

Ireland has uniform electricity pricing, SEAI grants, and Clean Export rates nationwide, so savings differences between provinces come down mainly to sunshine hours and household consumption patterns. Leinster's east-coast location gives it slightly more annual sunshine than the western provinces, with generation peaking in May. Country-wide incentive details are covered on the Ireland solar page.

Your usage & system size Leinster

Energy usage & tariffs

Properties in Leinster average around 15 kWh daily electricity consumption — and with electricity costs continuing to rise, solar can make a real difference to household budgets. Homes that shift heavy usage to daylight hours — running dishwashers, washing machines, and charging EVs during the day — often get more value from every solar panel.

Simple changes like sealing draughts, upgrading to LED lighting, and setting hot water timers often cost far less than extra solar panels and deliver immediate bill savings.

Estimated at 75% of the retail grid rate. A battery lets you store daytime solar and export during expensive peak hours, so each exported kWh is typically worth more than a flat feed-in tariff. Real returns depend on your time-of-use tariff and battery efficiency.

Solar system size

Most solar installers in Leinster would recommend starting at around 3.9kW for a household using 15 kWh per day, with room to go larger if budget allows. Systems sized between 5.9kW and 7.9kW perform best, accounting for natural fluctuations in solar production.

A 5.9 kW system in Leinster generates approximately 21.8 kWh daily on average, with seasonal variation from 1.97 kWh/kW/day in December to 4.62 kWh/kW/day in May.

A 6 kW system in Leinster can generate approximately 8105.0 kWh annually based on local sun conditions.

Battery storage

Even without a battery, 45% self-sufficiency from a 5.9 kW system in Leinster means a significant reduction in your electricity bills. Including a 10 kWh battery typically raises annual self-sufficiency to around 88%, with grid reliance dropping to 12%.

Whether a battery is worth the investment depends on your tariff, usage patterns, and how much you value energy independence — the Photonik tool can help you compare scenarios.

The sweet spot for most households is 5 – 13 kWh — larger batteries add independence but with diminishing payback, especially where feed-in tariffs are low.
