Garden Solar Panels UK: Shed, Garage & Plug-In Options (2026)

Why garden solar makes sense

Not everyone has a south-facing roof, and not everyone wants to bolt panels to their house. Garden installations let you choose the best angle and orientation for your location, avoid roof-related planning complications, and keep your system portable if you move.

With the 2026 reforms making plug-in solar more accessible in the UK, garden-based setups are one of the easiest ways to start generating your own electricity — especially if you have a shed, garage, or just a patch of sunny lawn.

Option 1: Ground-mount stand in the garden

The simplest approach. A ground-mount frame holds your panels at the optimal angle (around 35° for Southern England) and can be positioned wherever you get the most sun. Most ground stands are weighted or staked — no concrete foundations needed.

• Best for: Open gardens with good sun exposure
• Typical cost: £50–150 for the stand, plus panels and microinverter
• Pros: Optimal angle, easy to reposition, no structural work
• Cons: Takes up garden space, needs weatherproof cable routing to the house

Option 2: Shed-roof solar

If your shed gets decent sun, mounting panels on its roof is a clean solution that doesn't take up garden space. Shed roofs are usually easy to mount to (a few brackets and self-tapping screws), and you can run the cable to the house via the garden.

• Best for: Sheds with south- or west-facing roof space
• Typical cost: £30–80 for brackets, plus panels and inverter
• Pros: Uses otherwise wasted space, panels are out of the way
• Cons: Shed roof angle may not be optimal, cable run to house can be long

Option 3: Garage roof or wall

Similar to shed-roof mounting, but garages often have larger, sturdier roofs. Attached garages are ideal because the cable run to the house is short. Detached garages work too — you just need to route the cable across the garden.

• Best for: Attached garages or garages close to the house
• Typical cost: £50–100 for brackets, plus panels and inverter
• Pros: Sturdy mounting surface, often close to the house
• Cons: Garage roofs may be north-facing, potential for shading from the house

Option 4: Fence or wall mount

Garden fences and boundary walls can work as vertical mounts for solar panels. The angle isn't optimal (vertical panels produce roughly 65–70% of a tilted panel's output), but it's a practical solution if you're short on space.

• Best for: Small gardens with south-facing fences or walls
• Typical cost: £40–100 for brackets
• Pros: Doesn't use garden space, no ground work needed
• Cons: Lower output due to vertical angle, fence must be sturdy enough

What you need

Regardless of where you put the panels, a garden plug-in solar system needs:

1. Solar panels — one or two panels rated 100–400W each. See our Solar Panels Directory.
2. A microinverter — converts DC to AC and plugs into your home. See our Inverter Directory.
3. Mounting hardware — ground stand, roof brackets, or wall mount.
4. Outdoor-rated cable — if the panels are more than a few metres from the socket.
5. A standard wall socket — the microinverter plugs in here.

How much will a garden solar setup cost?

A complete garden plug-in solar system in the UK typically costs:

Planning permission

Ground-mounted solar panels in your garden don't normally need planning permission in England and Wales, provided:

• The panels are no more than 4 metres high
• They don't cover more than 50% of the garden area
• The installation isn't in a conservation area or World Heritage Site

Plug-in solar systems with non-permanent fixings are even simpler — they're generally treated as temporary structures. If in doubt, check with your local planning authority.

Tips for getting the most from garden solar

• Angle matters: In the UK, the optimal tilt is around 30–40° from horizontal, facing south. But even suboptimal angles generate useful energy.
• Watch for shadows: Trees, fences, and buildings cast shadows that change throughout the day and year. Position panels to avoid shading during peak sun hours (10am–3pm).
• Secure your panels: Ground-mounted panels can catch wind. Use weighted bases or stakes, and check after storms.
• Keep cables safe: Outdoor cables should be in conduit or rated for outdoor use. Don't run cables across paths where they might trip someone or get damaged.
