Solar services in Wales

Solar Cymru does not install anything itself. Instead, we explain what each type of solar job involves in Wales, and then we pass your enquiry to MCS-certified installers if you ask us to. Each page below sets out what a fair quote should cover and which Welsh rules apply.

Most homes start with panels on the roof, while some add a battery later to use more of their own power. Farms, shops and offices face bigger systems and stricter grid rules, so commercial solar has its own page. Some homes also weigh a battery against an electric car or a heat pump, since both change when you use power. For example, larger systems need the network operator's agreement before they connect.

What a good quote includes

A good quote starts with a survey of your roof or site. The installer should check the structure, the shade and the space for panels, and then give you a yield estimate in writing. Similarly, a battery quote should state the usable capacity, not only the headline size. If a quote skips these steps, ask why before you go further.

Each service page also lists the questions worth asking before you sign. For instance, ask who handles the grid paperwork and what the warranty covers. Our guide to choosing an installer in Wales goes through these checks in more detail.

Welsh rules that shape each service

Welsh rules shape all three services. Planning limits differ in national parks and conservation areas, while two network operators cover different parts of the country. Our guide to planning permission in Wales and our guide to the grid and solar export explain both, so read them before you ask for quotes.

When you know what you want, you can request installer quotes through our short form. Nothing reaches an installer until you send it, and the service costs you nothing.
