If you’ve taken a walk around any neighbourhood in Cork, Waterford, or anywhere around Ireland lately, you’ll see the blue-black shimmer of solar panels on almost every second roof. But there’s a secret to these systems that many people still don’t fully understand: in 2026, the grid has become your customer.
The financial logic of solar has undergone a radical shift. It’s no longer just about avoiding a bill from the ESB; it’s about sending them one. Here is exactly how the Micro-generation Support Scheme (MSS) works and how you can start seeing credits hit your account.
The MSS is the government’s framework to encourage us all to become “prosumers”, people who both consume and produce energy. It consists of two main financial pillars:
SEAI Grants Available: Homes (up to €1,800) & Businesses (up to €162,600).
As of February 2026, there is no “fixed” national rate. Instead, the Commission for Regulation of Utilities (CRU) mandates that suppliers must offer a “competitive market rate.” We have seen a steady increase in these rates as suppliers compete for “green” customers.
Current 2026 rates across Munster generally fall between 16c and 25c per kWh:
The Financial Impact: A typical 4kWp solar system in a Munster home might generate 3,800kWh a year. If you use 70% of that yourself and export the remaining 30% (1,140kWh), at a 20c rate, you’re looking at €228 in direct credits on your bill annually. When you add that to the €800+ you’ve saved by not buying electricity from the grid, the payback period for your system drops to roughly 5–7 years.
One of the most important updates for homeowners this year is the extension of the Tax Disregard. Originally set to expire, Budget 2026 confirmed that the €400 income tax disregard for microgeneration has been extended until the end of 2028.
What does this mean for you? You can earn up to €400 per year from selling electricity back to the grid completely tax-free. You don’t need to declare it to Revenue, and it doesn’t attract USC or PRSI. It is pure profit that stays on your utility account, helping to wipe out your winter heating bills using the “credit” you built up during the sunny Munster summer.
During your installation, we (your registered installer) submit an NC6 Form to ESB Networks. This notifies them that your house is now a power plant. They need this to update your Meter Point Registration Number (MPRN) to “Export” status.
To get paid for the exact amount you send back, you need a smart meter. ESB Networks has now completed the rollout for most 24-hour and day/night meters across Munster. If you still have an old mechanical meter, the NC6 form will trigger an “express” replacement within roughly four months.
Note for 2026: As of January, the CRU has tightened rules on “deemed” (estimated) payments. To maximise your earnings, having an active smart meter is now essential.
You must sell your power to the same company you buy your power from. Because rates vary from 16c to 25c, we always tell our clients: Shop around. In 2026, the best “Solar Tariff” isn’t just the one with the cheapest night rate; it’s the one that balances a low buy-rate with a high sell-rate.
Once registered, you don’t need to do a thing. Your smart meter communicates directly with your supplier, and you’ll see a line item on your bill titled “CEG Credit” or “Microgen Export.” Most suppliers now issue these credits quarterly, though some like Pinergy offer monthly visibility via their app.
This is a common question. While a battery (like the GoodWe Lynx Home U Series) encourages you to store your power for evening use rather than exporting it, it doesn’t “kill” your export earnings.
In fact, during the long Munster summer days (where the sun is up at 5:00 AM), your battery will often be 100% full by 10:30 AM. From that point until the sun goes down, every single watt your panels produce is exported to the grid. A battery simply gives you the choice: Use it, Store it, or Sell it. By storing power for the 5:00 PM to 7:00 PM peak (when electricity is most expensive to buy), and selling the “excess” at 25c/kWh, you are playing the energy market like a pro.

Navigating ESB Networks and the various supplier tariffs can be a headache. At Munster Solar, we specialise in the “full-circle” service. We ensure your NC6 is filed the day of installation, your GoodWe inverter is commissioned to talk to the grid correctly, and we can even advise you on which Munster-based suppliers are offering the best CEG rates this month.

For standard homes, the limit is governed by your “Maximum Export Capacity” (MEC), usually 6kW for single-phase connections. If you have a massive array, you might need a different connection type (NC7), but for 99% of Munster homes, the standard setup is perfect.
Yes, for now. However, the government has signalled that as the cost of solar hardware drops, the grant may be reduced by €300 per year starting in the future. Locking in your 2026 installation ensures you get the full €1,800.
The grid is ready to pay you for your sunshine. At Munster Solar, we ensure your installation is optimised for both self-consumption and maximum export profit. Contact us today for a free site survey across Munster.
