How do you choose a solar panel installer in Mayo?
Check SEAI Registration
Only SEAI-registered installers qualify you for the €1,800 grant. Verify your installer on the SEAI register. 43 installers serving Mayo are currently registered.
Compare Multiple Quotes
Get at least 2–3 written quotes with itemised breakdowns. A typical 4kWp system in Mayo costs €5,000–€8,000 before the grant. Ensure quotes include panels, inverter, mounting, electrical work, and BER assessment.
Verify Insurance & Warranties
Confirm public liability insurance and ask about workmanship warranty (minimum 5 years). Panel manufacturers typically offer 25-year performance guarantees and inverters come with 10–12 year warranties.
Read Customer Reviews
Check Google, Trustpilot, and Facebook reviews. Ask for references from recent installations in Mayo. Look for detailed reviews mentioning communication, tidiness, and after-sales support.
Check Equipment Brands
Ask which panel and inverter brands are used. Tier 1 solar panel manufacturers (e.g. JA Solar, Trina, Canadian Solar) offer the most reliable long-term performance. Avoid quotes that don't specify equipment.
Confirm Grant Handling
A good installer helps with the SEAI grant application, ESB Networks NC6 form, and arranges the post-works BER assessment. Ask whether these are included in the quoted price.
