Can I put a plug-in solar kit in my garden?

Yes — a garden or patio is the position these kits are designed for. You need a firm, level surface that can take the weight and wind loading, ballast to hold the frame down, and a suitable external socket within reach of the manufacturer-supplied lead.

Which way should the panels face?

Due south at roughly 30° gives the highest annual output. South-east or south-west loses only about 5%, and east or west around 15%. If your household uses most electricity in the evening, a west-facing position can save more money than a south-facing one even though it generates less.

Do I need to bolt it down?

The frames are designed to be ballasted rather than fixed, which is what keeps the installation reversible. Ballast weights are not included with the kit — use the weight and placement specified in the manufacturer's instructions, and never guess.

Can I run it from an indoor socket through a window?

No. The device must connect directly to a suitable fixed socket using the manufacturer-supplied plug. Extension leads, multiway adaptors, travel adaptors and plug-in RCD adaptors are all prohibited, and trapping a cable in a window frame damages it.

How far from the house can it go?

Only as far as the manufacturer-supplied lead reaches from a suitable external socket. You cannot extend it. In practice this puts the kit within a few metres of the wall, which is usually where the firmest surface is anyway.

Will it survive British weather?

The panels and inverter are built for permanent outdoor use. The risk is not rain, it is wind: an under-ballasted frame in an exposed position is the one failure mode you can create yourself. Follow the ballast specification and check it after severe weather.

Garden and patio solar: where plug-in kits actually work best

A garden, patio or ground-accessible flat roof is where a plug-in solar kit works best: the mounting hardware is designed to stand free rather than fix to a wall, you can point it where the sun actually is, and you can reach it to clean it. What you need is a firm level surface, a suitable external socket, ballast, and permission to use the space.

Best position: Free-standing, south-facing
Surface: Firm, level, load-bearing
Socket: Suitable external socket

Why ground level is the right answer

Plug-in solar in Europe is often photographed hanging from an apartment balcony. That is a different hardware category. The kits SocketPower supplies are ground-mount systems: The supplied mounting hardware is designed for gardens, patios, ground installations and, where the kit supports it, suitable wall installations.

The advantages are real rather than a consolation. A free-standing frame can be angled properly instead of being dictated by the surface it hangs on. It can be turned or moved if a tree grows or you move house. And you can reach it — to clear leaves, wipe off winter grime and check the ballast — without a ladder.

Where it goes

A patio, terrace or paved area with an unobstructed southern outlook.
A lawn or gravel area with firm, level ground beneath.
A ground-accessible flat roof — a garage or extension you can safely walk on and that can carry the load.
A sound, load-bearing wall, where your kit is supplied with the hybrid ground/wall mounting system (Compact, Plus and Max — the Duo is ground-mount only).

Not a pitched roof, not a balcony railing, and not anywhere you cannot safely reach.

Orientation, tilt and the shading test

Position drives output more than any other decision you make after choosing a kit.

Effect of orientation on annual output, all else equal
Orientation	Share of a south-facing figure	Best suited to
Due south	100%	Maximum annual generation
South-east / south-west	≈95%	Almost as good; usually the practical choice
East	≈85%	Households with heavy morning usage
West	≈85%	Households home in the late afternoon and evening
North	≈55%	Avoid unless there is genuinely no alternative

Tilt matters too: roughly 30° from horizontal is the reference case. A near-vertical position loses around a quarter of the annual figure, which is one reason railing-mounted systems underperform free-standing ones.

Surface, ballast and wind

It must be installed in accordance with the supplier instructions and your own site conditions.

Before the frame goes down

The surface is firm, level and will not sink or shift when wet.
The surface can carry the weight of the frame, the panels and the ballast together.
The position is not a wind funnel between two buildings or at an exposed corner.
Ballast is sourced and matches the weight and placement in the manufacturer's instructions.
There is clear space behind and beneath the panels for air to move.
Nothing about the position blocks a fire escape, a footpath or access to a meter or stopcock.

Re-check the ballast after any severe weather. It is a two-minute job and it is the single most useful piece of maintenance a plug-in solar owner does.

The external socket requirement

You will need a suitable external socket at the installation location.

The device plugs directly into a suitable fixed socket using the manufacturer-supplied plug and lead. If you do not have an external socket in the right place, adding one is work on your fixed wiring and is a job for a qualified electrician — not a reason to reach for an extension lead. Extension leads, multiway adaptors, travel adaptors and plug-in RCD adaptors are prohibited with these devices.

The circuit also needs modern residual-current protection. Our safety guide walks through the checks, including the pre-purchase suitability checker.

Permissions, neighbours and the view

Reversible mounting does not remove the need for consent. If you rent, ask your landlord. If you lease, check the lease and ask the freeholder or managing agent. If your property is listed, in a conservation area or subject to an Article 4 direction, speak to your local planning authority about anything visible from outside.

Renters and leaseholders have their own guide: plug-in solar for renters and flats.

Which kit suits a garden or patio

Choosing by available space
Kit	Panels	Footprint	Choose if	RRP
SocketPower Pro Compact 515W	1 × 515W	One panel width	Smallest footprint — one panel in a garden, on a patio or on a suitable wall, and the lowest entry price.	£599
SocketPower Pro Duo 890W	2 × 445W	2 panels side by side	A balanced pair of panels for a fuller day-long output profile on a typical home, sited at ground level.	£999
SocketPower Pro Plus 1030W	2 × 515W	2 panels side by side	More DC capacity than the inverter can pass at once, so it reaches full output earlier and holds it longer in cloud.	£1,099
SocketPower Pro Max 1260W	2 × 630W	2 panels side by side	The largest array in the range — best where space allows and low-light generation matters most.	£1,199

Every kit runs the same 799 VA microinverter. Going up the range buys more panel area working for more of the day, not a higher peak — see 800 VA explained.

Plug-in solar in Great Britain: the framework covers single-phase solar PV with a maximum inverter apparent output of 800 VA, and SocketPower devices are limited to 799 VA continuous AC output. Plug-in batteries and battery-integrated devices are outside the framework and are not sold by SocketPower. The current G98 arrangements allow one plug-in solar device per household, and network notification remains required — SocketPower handles the applicable notification for kits bought from us. This framework applies in Great Britain from 27 August 2026 and not in Northern Ireland. Always follow the instructions supplied with your product, check that your socket and circuit are suitable, never use extension leads, multiway adaptors, travel adaptors or plug-in RCD adaptors, and obtain any permissions you need before installing.
