Choosing the right electricity tariff after installing solar
- Check your evening import: most homes still buy electricity after sunset, so unit rate and standing charge remain important.
- Understand battery usage: if you have a battery, consider whether you will charge it from solar only or also during cheaper off-peak periods.
- Compare the full bill: do not choose a plan based only on the lowest advertised unit rate.
- Review time-based plans carefully: smart tariffs can suit some households, but only if your usage pattern matches the cheaper time bands.
Before switching, review current market pricing on our Electricity Rates Ireland guide.

- What warranties apply to the panels, inverter, and battery?
- What monitoring tools are included?

After installation: review your electricity plan
Once your solar PV system is installed and generating electricity, it is worth reviewing your electricity plan to make sure it suits your updated usage pattern. The right tariff can help protect the savings from your investment.
