Solar & Battery Installation Dublin Local Installers & Quotes
Homes in Dublin typically use around 15 kWh of electricity per day, and the city's sunny climate makes solar an attractive option. Production peaks in August and eases in December, but a properly sized system delivers strong returns year-round.

Energy Usage
To choose the right solar system in Dublin, start by understanding your daily electricity consumption. Most households in Dublin use around 15 kWh per day, whilst energy efficient homes can reduce this to roughly half.
Consider reducing your energy consumption first through better insulation and efficient appliances, as this can reduce the solar system size needed and improve your investment returns.
Typical energy usage per person per day in Dublin:
Note: Actual usage varies depending on property size, building efficiency, climate, and appliances.
Solar System Sizing
A 3.9kW solar system would typically cover your average daily electricity consumption. The 5.9kW to 7.9kW range accounts for real-world conditions — cloudy days, seasonal variation, and the fact that panels rarely perform at peak all day.
A 5.9 kW system in Dublin generates approximately 21.8 kWh daily on average, with seasonal variation from 1.96 kWh/kW/day in December to 4.62 kWh/kW/day in August.
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 Dublin
Solar Battery Sizing
A solar-only system in Dublin covers about 45% of your energy needs during daylight hours, but without a battery the 55% you use at night still comes from the grid. Beyond the bill savings, a 10 kWh battery at 88% self-sufficiency also provides backup power during outages — an increasingly valued feature for homeowners.
Local incentives and rebates can significantly improve battery economics — check what's available in Dublin and use the Photonik design tool to factor them into your calculations.

Solar & Battery System Cost Dublin
Understanding Solar & Battery System Costs
A 5.9 kW solar system in Dublin costs approximately €11,282, while adding a 10 kWh battery increases the total to around €21,567. Solar installations typically pay for themselves within around 9.3 years, whilst batteries extend payback but deliver significantly higher energy independence.
Whether you choose solar-only at €11,282 or add a battery at €21,567, the investment is typically recovered well within the system's 25-year lifespan.
