Plug-in solar panels in Plymouth
Three things change depending on where you live: who you notify, how much the panel actually makes, and who has to say yes first. Here are all three for Plymouth.
In Plymouth you notify National Grid Electricity Distribution
National Grid Electricity Distribution · South West licence area
Your network operator is fixed by your postcode. You cannot choose it and switching electricity supplier does not change it. Great Britain is divided into fourteen licence areas, and Plymouth falls in the South West licence area.
Same licence area as Bristol, still carrying the old Western Power Distribution name on some paperwork.
G98 notification is not optional and it is not the same thing as telling your supplier. It is a short form, it is free, and the QR code on your kit links straight to the right one. Do it before you connect, not after.
What 800W realistically makes in Devon
These are irradiance model figures for 800W of panel, not measurements from a roof down the road. Treat them as a ceiling you will fall short of rather than a target.
840 kWh
Per year, south facing, angled properly on a garden frame or flat roof with nothing shading it.
520 kWh
Per year, mounted flat against a south-facing balcony railing. The convenience costs you output.
25–60%
The share you use as it is generated. The rest goes to the grid for nothing. Being home in the day is worth more than a bigger kit.
Plymouth has the highest modelled solar yield of any city on this list. It also has serious salt and wind exposure on the waterfront, so the same coastal caveat applies as in Brighton and Aberdeen.
Two panels on one 800VA inverter. The sweet spot for a typical home's background load, and the largest output the rules allow.
Housing stock in Plymouth
Plymouth has a lot of postwar rebuild housing with generous plots by city standards, which makes garden frames straightforward. The waterfront flats at Royal William Yard and Mount Batten are the balcony stock and face south across the Sound.
The Barbican and Royal William Yard are heavily listed and any fixing to the fabric is a listed building consent question. Freestanding frames on a private terrace are a much simpler conversation.
Permission questions locally go to Plymouth City Council, though for a freestanding panel in a private rear garden you are usually dealing with a lease or a landlord rather than a planning officer.
The national rules apply here as everywhere

Straight answers
Which DNO do I notify in Plymouth?
National Grid Electricity Distribution, in its South West licence area. G98 notification is mandatory before you connect a plug-in solar kit, and it goes to your network operator, not your electricity supplier.
How much electricity will a plug-in solar kit make in Plymouth?
An 800W array in Plymouth models at roughly 840 kWh a year at optimal tilt, or around 520 kWh flat against a vertical balcony rail. You only save money on the share you use as it is generated.
Is it actually sunnier here than the rest of the country?
Yes, measurably. Plymouth models higher than anywhere else we cover. That does not make the payback fast, but it does mean a kit here will beat the same kit in Glasgow by roughly a fifth over a year.

Kits available from 27 August 2026
That is the date SI 2026/848 comes into force and plug-in solar becomes legal to self-install in Great Britain. Certified kits are listed here as soon as they are available.
