Solar installer due diligence

How to check a solar panel company in Ireland

Solar installations combine a significant deposit, technical promises and a long warranty period. Check both the current SEAI listing and the legal company expected to perform the contract before money moves.

Quick answer

Check the scheme, company and contract

Step-by-step

A reliable review checklist

  1. 1

    Check the SEAI list

    Search the current registered Solar PV Companies list and match the name and registration details to the quotation.

  2. 2

    Verify the company

    Search the legal company number and compare status, age, address and the people behind the contract.

  3. 3

    Compare several quotes

    Assess design assumptions, generation estimates, equipment, warranties, total cost and exclusions on a like-for-like basis.

  4. 4

    Check delivery capacity

    Speak with recent customers and request evidence for insurance, qualifications and who will physically perform the work.

  5. 5

    Control the deposit

    Define what the deposit buys and link later payments to equipment delivery, installation and commissioning evidence.

  6. 6

    Preserve the warranty file

    Keep the company report, contract, product data, serial numbers, declarations, invoices and handover documents together.

SEAI registration and company history answer different questions

SEAI maintains a list of registered Solar PV Companies for grant-supported work and states that applicants should ensure their selected company appears on it. SEAI also makes clear that registration does not approve, guarantee or warranty the company or its work.

That is why the corporate check still matters. Match the listed provider to the entity named in the contract and bank account. A similar trading name or salesperson's email is not enough for a material deposit.

  • Current SEAI company listing
  • Exact contracting entity and company number
  • Named installer and electrical responsibilities
  • Bank beneficiary and deposit invoice

Read the company timeline before relying on a long warranty

Solar proposals commonly include equipment and workmanship warranties extending well beyond installation. A warranty is only useful if you understand who provides it: manufacturer, distributor, installer or another group company.

The full company report lets you review available directors and filing history alongside company age and status. A newer installer may still be capable, but the shorter record should lead to stronger references, clearer manufacturer coverage and controlled payment milestones.

Make the technical promise measurable

Require a written design covering system size, expected annual production, roof and electrical assumptions, equipment models, monitoring, grid connection responsibilities and any excluded building work. Compare quotes on the same assumptions rather than headline price alone.

SEAI recommends multiple quotes, online research, past-customer references and a written contract. Record who is responsible for grant paperwork and what happens if approval, equipment availability or site conditions change.

  • Specify panel, inverter and battery models.
  • Identify workmanship and product warranty providers.
  • Define commissioning and handover evidence.
  • Agree variation and cancellation procedures in writing.

Use the report when the deposit and warranty matter

A free profile supports the initial identity check. The €11.99 report is proportionate when the deposit is substantial, the company is unfamiliar or the warranty is central to your purchasing decision.

Use it with the current SEAI list, references, insurance, technical advice and a written contract. It cannot judge workmanship or forecast whether a business will still trade years later, but it makes the counterparty and its history visible before commitment.

Questions answered

Frequently asked questions

How do I check if a solar company is SEAI registered?

Search the current SEAI Solar PV Companies list and match the provider to the exact entity on your quotation.

Does SEAI registration guarantee the installation?

No. SEAI explicitly states that it does not approve, guarantee or warranty a company or its work.

Should the quote show a company number?

For an incorporated contractor, require the exact legal name and company number so you can identify the contracting party.

What should a solar deposit be linked to?

The contract should explain what it purchases and connect later payments to measurable delivery, installation and commissioning stages.

Why order the full company report?

It gives you available directors, filings and company history to retain with the contract and warranty evidence.
