Solar Export Payments Are Set to Fall: Why a Home Battery Now Beats a Bigger Array
Households with solar panels in Ireland have been warned that the rate paid for exporting excess electricity is set to fall, and could eventually be phased out. The warning, reported by the Irish Independent on 15 September 2026, landed alongside Budget 2027's move to raise the tax-free limit on solar export income from €400 to €600 a year. Together they point to one conclusion. The value of a home solar system is shifting from what you sell back to the grid to what you use yourself, and that is precisely the job a home battery does.
What Did the Warning Say About Solar Export Payments?
The warning reported by the Irish Independent set out that the rate paid for exported rooftop solar is set to fall and that support payments may be phased out as Ireland's solar market matures.
- Export rates have already come down. Pinergy cut its Clean Export Guarantee rate from 25c to 18.5c per kWh on 1 August 2026, and most suppliers now pay in a range of roughly 15.9c to 20c per kWh.
- Budget 2027 raised the amount of export income that is tax-free from €400 to €600 a year, which softens the blow for households that export a lot.
- Ireland passed 3 GW of installed solar in 2026, so midday export is increasingly a market with more sellers than buyers.
Why Are Solar Export Payments Falling?
Rooftops and solar farms across the country generate most of their power at the same time, around the middle of the day. When supply peaks, the grid cannot always use or carry it, and the value of exported units drops. It is the same pattern seen in other mature solar markets. The practical effect is that the return on an oversized array leans more heavily on export income that is getting thinner every year.
How Much More Is Self-Consumption Worth?
The gap between what you are paid to export and what you pay to import is the whole argument for a battery.
| Household setup | Self-consumption | Export value | Typical annual impact |
|---|---|---|---|
| Solar only | 30% to 40% | Roughly 15.9c to 20c per kWh | Lower savings as export rates fall |
| Solar plus battery | 70% to 80% | Smaller export volume | Larger bill reduction, protected from future rises |
*Figures correct as of October 2026. Export rates vary by supplier and are subject to change.*
Every unit you store and use is a unit you do not buy at the retail rate, which now runs above 30c per kWh including VAT for many households. That avoided cost is worth roughly twice the export rate, and it rises whenever prices rise.
Does a Battery Now Beat a Bigger Array?
For most homes, yes. Adding panels to chase export income is a bet on a rate that is falling. Adding a battery is a bet on your own bill, which keeps climbing. A battery also lets you charge cheaply overnight and draw on that power in the evening peak, and it keeps the lights on during an outage.
From 6 October 2026, homeowners can also claim a €600 SEAI grant towards battery storage, which improves the payback further, and the Budget move to a €600 tax-free export allowance is confirmed in the Government's Budget 2027 guide. Our solar batteries explained guide and our battery storage service page cover sizing and costs, and our complete guide to solar export payments explains the current rates in full.
How Do You Get More From the Solar You Already Have?
- Add a battery sized to your evening use rather than your whole daily demand.
- Shift heavy loads, such as a dishwasher or a heat pump, into the middle of the day.
- Charge an electric car during the solar peak, or on a cheap night rate.
- Move to a smart or dynamic tariff so you buy when power is cheapest.
- Check your supplier's current export rate before you assume your old one still applies.

Final Thoughts
Falling export rates do not make home solar a poor investment. They change where the return comes from. The households that get the most from their panels use the power on site, and a home battery is the simplest way to do that. Treat export income as a bonus rather than the plan, and the numbers hold up even if payments are reduced further.
