If you've noticed a smaller export credit on your latest electricity bill, you're not imagining it. The Electric Ireland solar panel tariff cut has reduced how much homeowners earn from exporting surplus solar electricity back to the grid — and if you have solar panels, it's worth understanding what this means for your savings, and how solar battery storage Ireland homeowners are increasingly turning to can help make up the difference.
What Happened with the Electric Ireland Solar Panel Tariff Cut?
Electric Ireland previously paid 21 cent per kWh for surplus electricity exported under the Clean Export Guarantee (CEG) scheme. That rate was reduced to 19.5 cent per kWh, meaning every unit of solar electricity you send back to the grid now earns you less than it used to.
While 19.5c/kWh remains competitive compared to some other suppliers, the cut is a reminder that export tariffs aren't fixed. They can move, and when they do, it directly affects the return on your solar investment — especially if you rely heavily on exporting rather than using your own power.
Why This Matters for Solar Panel Owners
Solar panels typically generate more electricity than a home uses during the day, and less than it needs in the evening. That surplus daytime power either:
- Gets used directly in the home, or
- Gets exported to the grid for a credit under the CEG scheme
When the export rate drops, homes that send a lot of electricity back to the grid feel the impact most. This is where battery storage solutions come in — because the less you rely on exporting at a lower rate, the less the tariff cut affects your overall savings.
How Solar Battery Storage Helps Offset the Tariff Cut
1. It Shifts You from Exporting to Self-Consumption
A solar battery stores your surplus daytime generation instead of sending it straight to the grid. That stored electricity can then be used in the evening, when your panels aren't producing but your household demand is often at its highest.
Instead of earning 19.5c/kWh for exported electricity, you're effectively saving the full retail import rate you'd otherwise pay your supplier — which is typically higher than the export rate. In other words, using your own solar power is usually worth more than exporting it.
2. It Reduces Your Exposure to Future Tariff Cuts
Export tariffs are set by suppliers and can change again. By increasing your self-consumption with solar battery storage in Ireland, you reduce how much of your return depends on a rate you don't control. Your savings become more predictable, because they're based on avoided import costs rather than a fluctuating export payment.
3. It Maximises the Value of Every Unit You Generate
Without a battery, unused solar power is exported the moment it's generated — even if you could have used it later that evening. With a battery in place, that same unit of electricity gets a second chance to be useful, either powering your home directly or reducing your next import bill.
Is Battery Storage Worth It After the Tariff Cut?
For many homeowners, yes — particularly those who use a significant portion of their electricity in the evenings. Here's a simple way to think about it:
- Check your usage pattern. If you're home in the evenings and use appliances, heating, or EV charging after dark, a battery captures the value you'd otherwise be exporting at a reduced rate.
- Compare import vs export rates. The bigger the gap between what you pay to import and what you earn to export, the more valuable a battery becomes.
- Factor in system size. Larger solar PV systems tend to generate more surplus, making a battery more worthwhile.
- Consider your existing setup. If you already have solar panels installed, adding a solar battery can be a straightforward next step to improve your return.
A Practical Example
Imagine a household exporting 2 kWh of surplus solar electricity a day that would otherwise cost around 30–35c/kWh to import. Under the reduced Electric Ireland export rate, that surplus earns 19.5c/kWh if exported. Stored in a battery and used later instead, that same electricity effectively saves the higher import rate — a noticeably better outcome over the course of a year.
FAQs
Why did Electric Ireland cut its solar export tariff?
Suppliers periodically review and adjust their Clean Export Guarantee rates based on market and regulatory conditions. Electric Ireland reduced its rate from 21c/kWh to 19.5c/kWh.
Does battery storage eliminate the impact of the tariff cut entirely?
Not entirely, but it significantly reduces your dependence on export income by allowing you to use more of your own solar electricity directly, which is typically worth more than the export rate.
Can I add a battery to an existing solar PV system?
In most cases, yes. A registered installer can assess your existing system and advise on compatible battery storage options.
Is battery storage covered by SEAI grants?
Battery storage grant support for residential solar PV was removed in February 2022 following the introduction of the Clean Export Guarantee scheme. It's worth discussing current supports directly with a registered installer, as grant schemes can change.
Final Thoughts
The Electric Ireland solar panel tariff cut is a clear signal that export income shouldn't be the only pillar of your solar savings strategy. With battery storage solutions, you can rely more on self-consumption and less on a rate that's outside your control — protecting your savings today and giving you more resilience against future tariff changes.
