About FairWatt
Know a fair price before you sign.
FairWatt is a free, independent Irish website. It answers two questions people ask before spending thousands on their home: is this solar quote a fair price, and which electricity plan is really cheapest for me?
What makes it different
- Real prices from real homes. 32 solar quotes shared anonymously by Irish homeowners, compared by price per kWp.
- Your own data. Upload your ESB Networks smart meter file and every plan is priced on how you actually use electricity. The file never leaves your device.
- Independent. FairWatt takes no commission from installers or electricity suppliers and does not sell leads. It is supported by voluntary donations.
Where the data comes from
- Solar quotes and reviews: shared by homeowners on this site and paraphrased from public community posts, without names.
- Installers: the SEAI register of solar PV companies.
- Electricity plans: suppliers' own price lists, checked every morning.
FairWatt does not switch your supplier and is not a CRU-accredited switching service. It is not connected to SEAI or any supplier.

Check it in a minute, then share it anonymously so the next person knows what’s fair.
Find an installer
See who installs in your county, how their prices compare with real community quotes, and whether customers paid what they were quoted. Shortlist up to three and send them all the same questions.
Find your cheapest electricity plan
Load the smart meter file from your ESB Networks account. Every plan is priced on each half hour you actually used, then we show where your power goes and what solar, a battery or an electric car would change.
Rates from suppliers’ own price lists, checked weekly.
Test changes against your real readings
Each half hour of your data is re-run with these panels, battery and car, then every plan is re-priced.
Prices include VAT, the supplier’s stated discount and the PSO levy (€6.67 a year). Standing charges differ for rural homes. Discounts usually last 12 months. Check the plan with the supplier before switching.
Before you sign
Tick what your quote includes. Anything missing becomes a question for the installer.

Watch-outs
- A large deposit asked for before anyone has surveyed your roof.
- Pressure to sign today, or a discount that expires this week.
- No panel, inverter or battery brand named.
- A price far below the community median with no clear reason.
- Extras such as a gateway, changeover switch or scaffolding that appear only after you sign.
