Solar Design Leinster
Energy Usage
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.
Typical energy usage per person per day in Leinster:
Note: Actual usage varies depending on property size, building efficiency, climate, and appliances.
Solar System Sizing
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.
Solar & Energy Savings
Calculate Heat Pump & EV Savings
Electrify your home by replacing gas heating, petrol vehicles, and other fossil fuel appliances with electric alternatives powered by clean solar energy. This delivers significant additional financial savings and substantial carbon emission reductions. Our calculator helps you compare costs and model the financial impact of switching to electric appliances and vehicles.
How Solar Reduces Your Electricity Bills
The calculations below show how your electricity bills change with solar. Your Old Bill of - per month (- annually) is calculated from your total energy consumption multiplied by the grid electricity rate. Your New Bill of - per month (- annually) accounts for solar generation, the percentage you use directly (self-consumption), remaining grid consumption, and feed-in credits for excess energy exported to the grid. This results in monthly savings of - (- annually).
Battery Storage Leinster
Solar Battery Sizing
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.

Solar & Battery System Cost Leinster
Understanding Solar & Battery System Costs
A 5.9 kW solar system at approximately €11,282 in Leinster can pay for itself through reduced electricity bills — often in under 9.3 years. With a 9.3-year payback and a 25-year panel lifespan, a solar system in Leinster can deliver many years of essentially free electricity after paying for itself.
The pricing breakdown includes equipment, installation labour, and applicable taxes. Use the sliders to adjust system size and battery capacity to see how pricing and payback change.
