A typical 3-bedroom house needs a 4–6kW system (8–14 panels). A 4–5 bedroom home may need 6–8kW (14–20 panels). Your installer will assess your usage and roof space.
The Sustainable Energy Authority of Ireland (SEAI) offers grants to make solar more affordable for homeowners.

Conservative estimate
During daylight hours, your panels generate electricity that powers your home. This "free" energy replaces electricity you'd otherwise buy from the grid.
Any surplus energy goes into your battery storage for use in the evening or overnight. This maximises self-consumption (typically 50-70%).
Even with a battery, some excess may go back to the grid. Under the Clean Export Guarantee (CEG), you earn 8–15c per kWh from your supplier.
Under Ireland's CEG scheme, all energy suppliers must offer export tariffs. Current typical rates range from 8–15 cent per kWh exported. For an average household, this can add €150–€300 per year in "passive" income from your solar system.
The final cost depends on several factors specific to your property and requirements.
Larger homes with more roof space can accommodate bigger systems, which improves savings potential but increases upfront cost. South-facing roofs are ideal.
Adding battery storage (€3,000–€6,000) increases self-consumption from ~30% to ~70%, dramatically improving your ROI. Highly recommended for most homes.
Premium panels (e.g., LG, SunPower) cost more but offer better efficiency, longer warranties (25+ years), and slightly higher output in Ireland's overcast climate.
Multiple roof faces, dormer windows, chimneys, or a roof in poor condition may increase installation time and cost. A flat roof may need mounting systems.
Planning to buy an electric car? Including a smart EV charger during installation is often cheaper than adding one later. Consider a 7kW home charger.
Higher electricity usage means more savings potential. If you're home during the day (retired, work from home), you'll use more of your solar generation.
