As more homes in Ireland install solar panels, one of the most common questions is: can you sell electricity back to the grid?
The answer is yes. Thanks to Ireland’s microgeneration supports, homeowners can export unused solar electricity and receive payment from their supplier. This guide explains how grid connection works in Ireland, how exporting electricity works, and how homeowners can start earning from their solar system.

What Is Grid Connection?
Grid connection simply means your renewable energy system is connected to Ireland’s electricity network so energy can flow both ways. When your solar panels generate electricity:
Your home uses the electricity first
Any unused electricity is exported to the national grid
Your electricity supplier pays you for that exported energy
This allows homes to reduce electricity bills and earn money for surplus generation.
How Does Selling Electricity Back to the Grid in Ireland Work?
Irish households can export electricity through the Clean Export Guarantee (CEG) under the Microgeneration Support Scheme. This means:
Excess solar electricity is sent back to the grid
Your supplier pays you per unit of electricity exported
Payments usually appear as credit on your bill
Export rates in Ireland typically fall somewhere around 15c–25c per kWh depending on the supplier and plan.
How the Grid Connection Process Works
If you are installing solar panels in Ireland, the process is usually straightforward.
Step 1 – Install Solar Panels
A qualified installer designs and installs a solar PV system suitable for your home.
Step 2 – Register the System
Your installer submits an NC6 form to ESB Networks to confirm the system can export electricity safely.
Step 3 – Smart Meter Records Exports
A smart meter tracks how much electricity you export to the grid.
Step 4 – Get Paid by Your Supplier
Your electricity supplier calculates your exported electricity and credits your account.
What Is the Clean Export Guarantee?
The Clean Export Guarantee (CEG) is the scheme that pays households in Ireland for selling electricity back to the grid. Key points include:
Available to homes generating renewable electricity
Payments made by your electricity supplier
Works with solar panels, wind, hydro, and micro-CHP
No application is required once your system is registered.
Each electricity provider in Ireland sets its own export rate.
Do You Need a Smart Meter?
Most homes need a smart meter to receive export payments, although some households may receive estimated (deemed) export payments if a smart meter has not yet been installed.
How Much Money Can You Make Exporting Electricity?
Export payments depend on:
Energy usage pattern (will your system produce enough excess power to sell)
Panel Orientation (are they in the optimal position)
Export tariff from your supplier (these varies from supplier to supplier)
Whether you use battery storage (will you store your power or sell it back to the grid)
Typical estimates for Irish homes:
System Size | Estimated Export | Potential Annual Payment |
3–4 kW Solar System | 700–1,200 kWh | €100–€250 |
5–6 kW Solar System | 1,000–1,800 kWh | €150–€350 |
Most homeowners save far more by using their solar electricity themselves rather than exporting it.
Is Income from Selling Electricity Taxable in Ireland?
Ireland has introduced a tax exemption on small amounts of income earned from microgeneration, subject to government policy. Homeowners can earn up to €400 per year tax-free from selling excess renewable electricity. This applies to electricity exported from your home system to the national grid.
Benefits of Connecting Solar to the Grid
Grid-connected solar systems offer several advantages:
Lower electricity bills
Payments for unused electricity
Reduced carbon footprint
Increased property value
Greater energy independence
For many Irish homeowners, solar panels now provide a strong return on investment when combined with grants and export payments.

Frequently Asked Questions
1. How do I connect my solar panels to the grid in Ireland?
A registered installer submits an NC6 form to ESB Networks confirming the system meets safety requirements. Once approved, your system can export electricity.
2. Do I need permission to sell electricity back to the grid?
Yes, your system must be registered with ESB Networks and installed by a qualified electrician.
3. How do I get paid for exported electricity?
Your electricity supplier measures exported electricity through your smart meter and provides payment or bill credit through the Clean Export Guarantee.
4. Do I need batteries to sell electricity?
No. Batteries are optional. You can export electricity directly from solar panels without storage.
5. Is selling electricity worth it in Ireland?
Yes, but most savings come from using solar energy in your home first. Export payments are an additional benefit.
