Understanding Net Metering and Export Tariffs in Ireland

If you're considering solar panels in Ireland, you've probably come across terms like net metering, export tariffs, and Clean Export Guarantee (CEG). But what do these terms mean, and how do they affect your return on investment?

This guide will walk you through what net metering is (and isn’t), how Ireland’s export tariff system works, and what homeowners in Dublin, Cork, and beyond should know before deciding to install solar.

What Is Net Metering?

Net metering is a billing system used in some countries where solar panel owners get full credit for any excess electricity they send back to the grid. For every kilowatt-hour (kWh) you export, you receive the same value as if you had consumed it.

In simple terms: your meter runs backwards when you export electricity.

However, Ireland does not use a full net metering model. Instead, it has adopted a Clean Export Guarantee (CEG), where you are paid a fixed rate per kWh for electricity sent back to the grid.

How Export Tariffs Work in Ireland

Rather than offsetting your imported electricity directly, Ireland’s system pays you in euros for the energy you export. These payments are made separately from your energy bill, and the amount is determined by your energy provider’s export rate.

Key points:

• You’re paid for each kWh exported
• Rates vary by supplier (e.g. SSE Airtricity, Bord Gáis, Energia)
• Payments are often made annually or quarterly
• You need a smart meter or export meter to qualify
• As of 2025, CEG rates range between €0.13 – €0.20 per kWh

This system still rewards solar owners, but it doesn’t offer 1:1 savings like net metering does in other countries.

Clean Export Guarantee (CEG) Explained

The CEG scheme ensures that households who export solar electricity are paid fairly, encouraging more solar adoption across Ireland.

To receive CEG payments, you must:

• Be connected to the grid via ESB Networks
• Have a smart meter or approved export meter
• Register with a participating electricity supplier
• Have a Microgeneration Notification (MGN) from ESB Networks

There’s no need for planning permission for typical domestic solar systems under 12 kW, and once registered, you'll automatically be eligible to receive export payments.

How Much Can You Earn from Exporting?

The amount you earn depends on:

• Your system size (e.g. 4–6 kWp is common for Irish homes)
• How much energy you don’t consume directly
• Your supplier’s export rate

Let’s say your solar system produces 4,000 kWh per year, and you export 50% of that. At €0.15 per kWh, you could earn €300 per year in CEG payments.

If you consume more of your solar power, your export earnings drop, but your savings on bills increase. That’s where solar batteries can come into play, but they aren't essential.

Is Net Metering Coming to Ireland?

It’s unlikely that Ireland will implement a full net metering model like in the US. Instead, the current export tariff system is designed to reflect market electricity prices and grid conditions.

Some providers may begin offering dynamic export pricing, where you earn more during peak grid demand. However, that’s still in development stages.

Tips to Maximise Your Export Value

Even without net metering, you can get more out of your solar investment:

• Choose the right supplier: Rates vary. Shop around!
• Check your smart meter settings: Ensure it records export data accurately
• Monitor your system: Use solar apps or monitoring tools
• Schedule high-usage appliances during the day: Reduce export and use more solar directly
• Consider future upgrades: Battery or EV integration can improve usage

Is It Worth Exporting Without a Battery?

Yes, especially if your system size is well-matched to your needs. While a battery can increase your solar self-consumption (from around 30–40% up to 70–80%), they come with extra costs.

Exporting surplus energy allows you to get paid for what would otherwise go unused. You might not be getting retail rates for it, but the savings plus export payments still make solar a strong investment in Ireland.

Final Thoughts

Ireland may not offer full net metering, but the Clean Export Guarantee still helps solar homeowners make the most of their energy. Understanding your export tariff and choosing the right energy provider can significantly improve your returns.

Whether you’re in Dublin, Cork, or anywhere in Ireland, installing solar panels is a smart step toward lowering your electricity bills, increasing your energy independence, and contributing to a greener grid.
