Poor Solar Panel Workmanship

Poor solar workmanship can leave a household with unsafe cabling, badly fitted panels, leaks, incomplete commissioning or a system that never performs as sold.

Why this matters

Solar panels can be a good investment when the system is specified honestly, priced fairly, suited to the property and installed properly. The issue is not solar technology itself. The issue is whether the sale, installation, workmanship or aftercare matched what you were told.

Workmanship complaints need clear, visual evidence and a careful timeline. A problem that looks obvious to the homeowner may still need photos, reports and installation documents to support a formal complaint.

We are not a government scheme, energy supplier or solar installer. Solar Panel Advice Centre helps homeowners organise the facts, understand the likely route and decide whether a free case review is sensible.

Where the issue may fit

The right route depends on who sold and installed the system, the nature of the workmanship fault and what your documents and photographs show.

  • installer remedial complaint
  • warranty or insurance-backed guarantee route
  • MCS, RECC or Green Homes Dispute Resolution where relevant
  • independent qualified inspection where technical evidence is needed
  • urgent qualified inspection for electrical, fire or structural safety concerns

How a free review helps

A free review is designed to sort the issue into the right category before you spend time on the wrong complaint. You can explain what happened in plain English, then add documents later if they are available.

The review normally looks at the written promises, photographs, installation paperwork, technical evidence and any aftercare or warranty response.

FAQs

Should I climb onto the roof for photos?

No. Take safe photos from ground level or ask a qualified professional.

Does messy cabling prove a claim?

It may support a workmanship complaint, especially with expert evidence or performance issues.

What if the installer offers a repair?

Keep the offer in writing and record what is done. Do not rely only on verbal promises.

Final call to action

If workmanship looks wrong or unsafe, document it and get the complaint route clear before repairs blur the evidence.
