Mounting & placement
Plug-in solar mounting systems: a practical guide
Where and how you mount a plug-in solar panel decides three things at once: how much it generates, how secure it is, and whether you need anyone's permission. This hub introduces the main mounting approaches and links to a detailed guide for each.Good mounting is mostly about orientation, secure fixing and wind loading. The right choice depends on your property — see plug-in solar for balconies, flats and gardens.

The main mounting approaches
| Approach | Best for | Detailed guide |
|---|---|---|
| Balcony railing | Flats and apartments | See balcony solar mounting |
| Wall mount | Walls with a clear, sunny aspect | See wall-mounted solar panels |
| Fence mount | Gardens and boundaries | See fence-mounted solar panels |
| Ground frame | Gardens with open space | See ground-mounted solar panels |
| Flat-roof ballast | Flat roofs and outbuildings | See flat roof solar panels |
Get the orientation right
A mount that points panels south at a sensible tilt will out-generate a poorly-aimed one regardless of panel quality. Balcony railings often force a vertical orientation, which produces less than an angled mount. Understand the trade-offs in solar panel direction and angle, and check for shading before you commit to a spot.
Security and wind loading
A solar panel is a large, flat surface that catches wind. Mounted high up — on a balcony railing or wall — a panel that works loose is a serious hazard to people below. Fixings must be appropriate for the surface and the panel, and rated for the wind loads at your location.
Safety and compliance
Permissions and your property
Mounting can raise permission questions even when the electrical side does not. Flats and leasehold homes may need landlord or freeholder permission; some changes touch planning permission; and it is worth telling your home insurer. Plug-in solar is also not yet legal to use in the UK — see the legal status.
Frequently asked questions
- What is the best way to mount a plug-in solar panel?
- It depends on your property. Balcony railings suit flats, ground frames and fences suit gardens, and ballasted mounts suit flat roofs. The best option combines a sunny, unshaded aspect with a secure fixing rated for wind loads.
- Can I mount solar panels myself?
- Mechanically, many ground and balcony mounts are designed for self-assembly following the manufacturer's instructions. But wind loading and fixings are safety-critical, and the electrical connection of a plug-in system is regulated and not yet legal to use in the UK. Get professional advice where failure could injure someone.
