What qualifications do you need to install solar PV in Ireland?
By Smart Solar editorial teamUpdated 7 min read
Short answer
To install grant-funded solar PV in Ireland as an individual, you need Registered Electrical Contractor status with Safe Electric, a recognised solar PV qualification with SEAI's course certificates, and a place on SEAI's Renewable Installers Register. SEAI registration is complete only after its monthly onboarding session. Information as of November 2026.
Key points
- SEAI registers two things separately: the installer, a person who signs the Declaration of Works, and the company the homeowner contracts.
- Installers need Registered Electrical Contractor status with Safe Electric plus a recognised solar PV qualification.
- SEAI names two course certificates, 6N306 and 6N307, and also asks for a transcript of the completed modules.
- Registration is not complete until SEAI's monthly onboarding session. Allow up to five weeks from a complete application.
- Safe Electric publishes its fees on its own site. The SEAI pages we read state no registration fee, so ask SEAI before you budget.
Who is allowed to install grant-funded solar PV in Ireland?
A person registered with SEAI as a solar PV installer signs off the work, and the homeowner contracts a registered company or sole trader. This page covers that person. The business side is a separate registration.
SEAI's Solar PV Scheme page says you can register as a company, as an installer, or as both. The registered installer is the only person allowed to declare that an installation meets the scheme requirements, which in practice means signing the Declaration of Works for the homeowner.
If you are setting up the business as well, read how to start a solar installation company in Ireland alongside this page. It is one of the guides in our solar installer series for Ireland.
Why do you need to be a Registered Electrical Contractor first?
SEAI will only register a solar PV installer who is a Registered Electrical Contractor (REC) with Safe Electric, so REC status comes before everything else on this page.
Safe Electric is the legal regulatory scheme for electrical contractors in Ireland. It is run by the Electrical Safety Supervisory Body for the Commission for Regulation of Utilities. CRU's Safe Electric page says electrical contractors must be registered and adds that it is the law. It also says anyone who is not a REC and carries out electrical work in a domestic home can be reported to Safe Electric.
If you are not yet a REC, sort that out first. Our guide to becoming an EV charger installer walks through the REC step in more depth, and the same step applies here.
Which solar PV course certificates does SEAI ask for?
SEAI names two course certificates, 6N306 and 6N307, and asks for a transcript of the completed course modules as well.
SEAI's Renewable Energy Installers page adds that the certification must come from an accredited training provider. It lists solar PV, solar thermal, shallow geothermal and heat pumps as the technologies that qualify for its register.
SEAI's pages do not state course length or fees. Get both from the provider, and before you pay, ask in writing whether the course issues certificates 6N306 and 6N307 and a module transcript.
How do you get onto SEAI's Renewable Installers Register?
Register with SEAI as a Renewable Energy Installer first, then apply for the Solar PV Scheme through SEAI's online contractor registration form. SEAI says you cannot become a registered solar PV installer without that first step.
- Get REC status and appear in Safe Electric's Find an Electrician search.
- Finish the solar PV course and collect your certificates and transcript.
- Register on SEAI's Renewable Installers Register.
- Submit SEAI's online registration form for the Solar PV Scheme.
- Attend SEAI's monthly online onboarding session.
- Allow up to five weeks once your documents are complete.
The checklist below lists what SEAI asks for. SEAI emails the onboarding invitation once the earlier steps are in place, and registration is not complete until you have attended. The session is monthly, so check the next date early and plan your first jobs around it.
What is the difference between a registered installer and a registered company?
A registered installer is a person. A registered company is the business, either a company or a sole trader, that the homeowner contracts. SEAI registers them separately, and a company must have at least one registered installer in-house.
| Registered installer | Registered company | |
|---|---|---|
| Who it is | One qualified person | A company or sole trader |
| Role in a job | Signs the Declaration of Works | Is contracted by the homeowner and agrees to use only registered installers for that declaration |
| Main requirements | REC status, recognised solar PV qualification, certificates 6N306 and 6N307, Renewable Installers Register, listing in Find an Electrician | At least one in-house registered installer, an insurance declaration, a quality management system |
| Onboarding | Monthly online session | Monthly online session |

The in-house installer must be an owner, a director or a direct employee, so a sole trader who is also a registered installer can cover both roles. If one person carries that requirement for a company, there is a gap when they leave, so plan for a second registered installer.
Registration is not an SEAI endorsement. SEAI states that it does not approve, guarantee or warrant a company, an installer or their works. It registers them for tax and insurance compliance and on their commitment to the SEAI Domestic Technical Standards and Specification, the Code of Practice and the disciplinary procedures.
Checklist: the documents to have ready
Have these in one folder before you open the form, because SEAI's five weeks run from complete documentation.
- Safe Electric card or qualification certificate. Proof of REC status. If the Safe Electric number belongs to the company, SEAI also asks for a letter confirming your QC number, dated within one month of registering.
- Listing in Find an Electrician. SEAI cannot process the registration until you appear there.
- Course certificates 6N306 and 6N307. Both are named by SEAI as required.
- Transcript of completed course modules. Also required.
- Tax reference and Tax Access Number. You must provide both.
- Renewable Installers Register registration. Required before you can become a registered solar PV installer.
- Declaration of insurance. Installers submit theirs with the online registration.
- Onboarding session attendance. Registration is not complete until this is done.

Safe Electric publishes its fees on its How to Join page. As of November 2026 it lists an application fee of €112.70, then an annual fee, plus VAT, starting at €440.49 for ten or fewer electricians. The SEAI pages we read state no registration fee, so ask SEAI's solar PV team before you plan cash flow.
Typical mistakes when qualifying for solar PV work
Most delays come from paperwork that is almost right. SEAI's own advice is to email its solar PV team at solarpv@seai.ie before you start if you are in doubt.
- Registering the company and assuming the installer is covered, or the reverse. They are two registrations, and a company needs a registered installer in-house.
- Skipping the Renewable Energy Installer step. SEAI says you need it first.
- Applying with the company's Safe Electric number and no QC letter. SEAI asks for a letter confirming your QC number, dated within one month of registering, so an older letter must be replaced.
- Not appearing in Find an Electrician. SEAI cannot process the application until you are listed.
- Sending course certificates without the module transcript. SEAI asks for both.
- Leaving the insurance declaration incomplete. SEAI's top tips for company registration say to complete it fully.
- Treating submission as registration. Until you have attended the onboarding session, you are not registered.
- Promising customers a start date before SEAI confirms. Processing can take up to five weeks from a complete file.
What should you do once you are registered?
Meet the scheme's own conditions. SEAI's note on the company route says registration is provisional for six months from the first installation, and after that depends on a satisfactory inspection pass rate and at least five installations a year.
Homeowners can look registered firms up in SEAI's register of solar PV companies, which lists more than 500 firms (SEAI register, November 2026). For selling on the grant, see selling with the SEAI solar grant.
Smart Solar passes on solar PV enquiries from private homeowners to installers and installs nothing itself. Our terms with homeowners say we only work with installers registered for the work, so SEAI registration is a requirement for installers who sign up with us.
Questions and answers
Do you have to be an electrician to become a registered solar PV installer?
SEAI requires a registered solar PV installer to be a Registered Electrical Contractor with Safe Electric and to hold a recognised solar PV qualification. CRU says electrical contractors in Ireland must be registered with Safe Electric by law. A business owner without that status can still register a company, but the company needs a registered installer in-house, who can be a director, an owner or a direct employee.
Which course certificates does SEAI ask for?
SEAI's Solar PV Scheme page names two course certificates, 6N306 and 6N307, and also asks for a transcript of the completed course modules. SEAI's separate Renewable Energy Installers page says the certification must come from an accredited training provider. Neither page lists course lengths or fees, so ask the provider before you book.
Can a sole trader register for the SEAI Solar PV Scheme?
Yes. SEAI describes the registered company as the contracted entity, which can be a company or a sole trader. The company needs at least one in-house registered installer, who can be an owner, a director or a direct employee. A sole trader who is also a registered installer can register as both company and installer.
How long does SEAI registration take?
SEAI says it can take up to five weeks from when it receives all the correct documentation. Registration is also not complete until you attend the monthly online onboarding session, and SEAI sends that invitation by email once your earlier steps are accepted. Missing documents delay the process, so check your list before you submit.
How much does SEAI and Safe Electric registration cost?
Safe Electric publishes its fees on its own site. As of November 2026 it lists an application fee of €112.70, then an annual fee, plus VAT, that depends on how many electricians the firm has. The SEAI pages we read state no registration fee, so ask SEAI's solar PV team. Course fees are not stated on SEAI's pages either, so request quotes from training providers.
Does SEAI registration mean SEAI approves my installations?
No. SEAI says it does not approve, guarantee or warrant a company, an installer or their works. Registration confirms tax and insurance compliance and a commitment to SEAI's technical standards, Code of Practice and disciplinary procedures. Describe yourself to customers as SEAI registered, not as SEAI approved.
