Solar panel installers in Wales

Give shortlisted companies your postcode, property type, electricity use and the work you want done. Ask for an assessment of roof condition, shade, access and the electrical installation before choosing a system. Compare the proposed equipment and installed scope, not only a headline panel count. A site-specific estimate should make its assumptions about generation and household consumption clear.

Use the official Nest assessment route

The Welsh Government’s Nest guidance explains the current route to advice and potential home energy improvements. An assessment determines eligibility and the measures offered; do not assume a particular solar project is automatically funded. Our Nest directory category does not establish entitlement or current company approval.

Plan access and aftercare as part of the installation

Explain any narrow access, roof complexity, remote location or restrictions on working hours when arranging a survey. Ask whether scaffolding and other access equipment are included and who coordinates any roof repairs. Establish travel charges and the service area for subsequent visits. The company nearest your address is not necessarily the only one serving it, so confirm coverage directly.

Separate storage, export and funding decisions

If you are comparing a battery package, ask for usable capacity, power limits, compatibility and backup capabilities if required. Compare the battery installation checklist with the quote. Check electricity-export arrangements with the supplier and treat projected export income separately from an installation grant. Do not rely on an old tariff or a fixed savings claim without seeing the assumptions.

Check current services and credentials

Ask for the exact legal business that will carry out the work and verify relevant claims through official scheme or manufacturer resources. A directory category is not a current register check. For faults, confirm equipment support, diagnostic charges and whether the company accepts systems installed by another installer. Request product and workmanship warranties separately and agree the handover records you will receive.

Frequently asked questions

Do all listed installers cover my address in Wales?

No. Listings show company locations and recorded details, not guaranteed service boundaries. Give the company your full postcode and project type to confirm coverage and any travel charges.

What should I send when requesting a solar quote?

Include your postcode, property type, the work required, electricity use and any existing panel, inverter or battery details. Ask for a site-specific design, installation scope, exclusions and separate equipment and workmanship warranties.

Does a directory badge prove current certification?

No. Check the exact business and relevant technology on the official scheme register or manufacturer resource. Historical directory categories and company-stated claims are not independent certification.

Can I find someone to repair an existing solar system?

Ask whether the company accepts systems installed by others and supports your equipment model. A new-installation service does not automatically include repairs, so confirm the diagnostic charge and proposed work before booking.
