Key Takeaways
- The zero rate of VAT applies to the supply and installation of solar panels on private dwellings in Ireland.
- This zero rate came into effect from 1 May 2023.
- It requires a single 'supply and install' contract for the zero rate to apply; supply-only purchases are subject to the standard rate.
- Ancillary equipment, including batteries, also qualifies for the zero rate if supplied and installed as part of the same contract.
What is the VAT Zero Rate for Solar Panels in Ireland?
From 1 May 2023, the supply and installation of solar panels on or adjacent to private dwellings in Ireland became eligible for a zero rate of VAT. This means that if you are having solar panels installed on your home, the VAT charged on the entire supply and installation service should be 0%.
The term 'private dwellings' includes houses (even domestic residences on a farm), apartments, duplexes, and other private dwellings like caravans or mobile homes that are immobilised by being attached to the ground. The phrase 'on or adjacent' means panels can be fitted onto the dwelling (e.g., roof-mounted) or ground-mounted beside it.
For this zero rate to apply, the supply of the solar panels and their installation must be the responsibility of the same business under a single 'supply and install' contract (April 2023).

Figures as of August 2026.
Does the Zero Rate Apply to Supply Only or Separate Installation?
The VAT zero rate specifically applies to a combined 'supply and install' contract for solar panels on private dwellings. If you purchase solar panels without an installation contract, the standard rate of VAT will apply to the goods.
If you arrange for the installation of solar panels under a separate contract from their supply, the zero rate does not apply to the installation service. Instead, the reduced rate of VAT may apply to the installation, subject to what Revenue.ie calls the 'two-thirds rule'. This rule states that if the cost of the goods used in carrying out the work exceeds two-thirds of the total price, the rate applicable to the goods then applies to the entire transaction (April 2023).
What About Solar Batteries and Other Equipment?
The zero rate of VAT extends beyond just the solar panels themselves. It also applies to ancillary equipment supplied and installed as part of the same 'supply and install' contract for solar panels on private dwellings. This includes components such as wiring, controllers, combiner boxes, and batteries (April 2023).
However, the Revenue guidance does not provide specific details on VAT rules for battery storage when supplied or installed independently of solar panels, or as a separate contract. If solar panels are included in a contract that also involves other fixtures, the zero rate may still apply to the solar panels and their ancillary equipment. The other fixtures will be taxed at their appropriate rate (reduced or standard rate) (April 2023).
Who is Not Eligible for the VAT Zero Rate?
The VAT zero rate for solar panels is specifically for private dwellings. It does not apply to installations on commercial buildings, industrial buildings, public buildings, retail shops, farm buildings, hotels, B&Bs, guest houses used for short-term accommodation, or holiday homes used for short-term accommodation (April 2023).
The Revenue guidance does not explicitly define "schools" or "mixed-use buildings" in the context of VAT rates for solar panels, beyond the exclusions listed. If your property falls into a category not explicitly defined as a private dwelling, you should seek further clarification.
