Prices checked at each source on 3 November 2026. Before the SEAI grant. VAT: 0% when the battery goes in with the panels, 23% on its own (SEAI Solar PV Scheme Application Guide, v6.0, 12 Oct 2026 (read 3 Nov 2026)). The spread is wide because battery size, brand and whether a new inverter is needed all change the price, so ask for the battery itemised on your quote.
Is there a grant for a solar battery?
Yes: a flat €600 from SEAI for a battery of 5kWh or more, on top of up to €1,800 for the panels, so €2,400 at most.
| What you fit | Panel grant | Battery grant | Total |
|---|---|---|---|
| 2kWp | €1,400 | – | €1,400 |
| 3kWp + battery | €1,600 | €600 | €2,200 |
| 4kWp | €1,800 | – | €1,800 |
| 4kWp + battery | €1,800 | €600 | €2,400 |
From SEAI Solar PV Scheme Application Guide, v6.0, 12 Oct 2026 (read 3 Nov 2026). Homes with a qualifying welfare payment or in the Rental Accommodation Scheme can get up to €9,000. The grant must be approved before any work starts. How to apply.
Is a battery worth it in Wexford?
It saves about 17.5c on every kWh you store instead of export, so after the grant Purevolt's battery price needs about 4,000 to 4,600 stored kWh to pay back.
- Without a battery, power you don't use goes to the grid at 15.89c to 19.5c a kWh on standard plans (WattCharger, Aug 2026). Power you use yourself saves your unit rate, 36c to 45c per kWh on standard tariffs (Irish Times, 15 Oct 2026).
- Wexford's long sunny summers fill a battery most days. 10 panels on a south roof in Wexford town make about 643 kWh in June and 168 in December (EU PVGIS 5.2). In midwinter there is little spare to store.
- The Department of Energy worked out that a home with a battery and a 4kWp system could save as much as €900 a year, as reported by Irish Times, 25 Sep 2026.
- Our sums use the low end of standard unit rates and the most common export rate. A night-rate tariff or an electric car changes them, so ask the installer to work it out on your own bills.
Can I add a battery to panels I already have?
Yes, but a battery fitted on its own carries 23% VAT instead of 0%, so it costs more than one fitted with the panels.
From SEAI Solar PV Scheme Application Guide, v6.0, 12 Oct 2026 (read 3 Nov 2026). The installer may also need to change the inverter. If SEAI already paid a grant for your panels, ask SEAI whether the battery grant is open to you before you sign anything.
