How do you choose a solar panel installer in Merthyr Tydfil?
Check MCS Certification

Compare Multiple Quotes
Get at least 2–3 written quotes with itemised breakdowns. A typical 4kWp system in Merthyr Tydfil costs £6,600–£8,500 including 0% VAT. Ensure quotes include panels, inverter, mounting, electrical work, and EPC 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.

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 Paperwork Handling
A good installer helps with the DNO notification, MCS certification, and arranges the post-works EPC assessment. Ask whether these are included in the quoted price.
