Can I have ground-mounted solar instead of on the roof?
Yes, ground-mounted solar is an option if you have suitable land and your roof is unsuitable or too small. Panels sit on a frame angled for best output, which means you can orient them perfectly south. It costs a little more than a roof system because of the frame and groundwork, and larger arrays may need planning permission.
When ground-mounting makes sense
- Your roof faces north, is heavily shaded, or is too small.
- You have unshaded garden or field space.
- You want optimal south-facing orientation and easy access for cleaning.
- You are sizing a larger system than the roof can hold.
Cost and planning
Expect to pay a little more than a comparable roof system due to the mounting frame, cabling run and groundworks. Small domestic ground arrays may fall under permitted development, but larger ones, or those near boundaries, often need planning permission, so check with your council.
Frequently asked questions
- Is ground-mounted solar more efficient?
- It can be, because you can set the perfect angle and direction and keep panels cool and clean, but the gain is modest versus a good roof.
- Does ground-mounted solar need planning permission?
- Small arrays may not, but larger ones usually do. Always confirm with your local planning authority.
