How Lydney compares
Small towns rarely get published solar figures, so here are the numbers for Lydney. It is one of 24 Gloucestershire towns we track, and it ranks joint 1st of 24 for solar yield, a town of 10,728 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,024 kWh per kWp a year, 2.81 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £916 of year one benefit, £247 of it from your own generation and £669 from export at 12p.
These are starting numbers, not a quote. The calculator below opens on Lydney's own PVGIS figure; change the panels, the battery or the export rate and it reruns. The design call replaces every assumption with your roof and your bills.
Any planning application in Lydney sits with Forest of Dean, and its official House of Commons Library settlement class is small town.
The charger is in the installed price but left out of payback: charging savings depend on your mileage and tariff, which the design call models properly.

NGED and your Lydney connection
National Grid Electricity Distribution (NGED) owns and runs the local electricity network in Lydney, as part of its West Midlands licence area.
What decides the paperwork is the inverter and battery output, not the number of panels. Up to 3.68kW per phase, a system follows G98: NGED is notified within 28 days of commissioning and nothing has to be approved first.
Above that, G99 means applying before the work is booked. NGED's guaranteed standards give 45 working days for a low voltage generation quotation, with £80 paid for each working day late.

Adding a heat pump or an EV charger in Lydney
A heat pump in Lydney
In December, the darkest month here, 12 panels in Lydney make about 220 kWh. That is when a heat pump runs hardest, so its running cost in Lydney comes down to the tariff and the flow temperature rather than the roof.
The Boiler Upgrade Scheme, open in England and Wales, takes £7,500 off an air source or ground source heat pump, or £2,500 off an air-to-air unit. Homes on oil or LPG with no mains gas get £1,500 more until March 2027 (gov.uk, checked 28 September 2026).
Charging an EV in Lydney
Lydney's July output, about 820 kWh from 12 panels, is several times the 70 kWh or so a typical home uses in daylight that month on our calculator's settings. Daytime charging turns that surplus into miles.
Renters and flat owners with private off-street parking can get 75% off a chargepoint and its installation, up to £500 per socket, until 31 March 2027 (gov.uk, checked 28 September 2026). The calculator above adds a 7.4kW smart charger from £1,100 installed.

Common questions about solar in Lydney
How much electricity do solar panels make in Lydney?
About 6,510 kWh a year from 12 panels (6.36 kWp), on PVGIS satellite data for Lydney: 1,024 kWh per kWp, or 2.81 peak sun hours a day on average. July is the strongest month, at about 820 kWh.
Is solar more expensive in Lydney?
Prices on this site are the same everywhere: £1,000 per kWp installed, which puts a 12-panel system at £6,360 in Lydney, and a Duracell Dura16 installed with solar at £4,450 on top. The local part is generation, about 6,510 kWh a year here, which is what drives payback.
Which DNO covers Lydney, and what does it need from me?
National Grid Electricity Distribution (NGED) covers Lydney. A home system of up to 3.68kW per phase is notified to NGED within 28 days of commissioning under G98, and nothing waits on approval. Larger outputs need a G99 application before work starts. NGED's guaranteed standards give 45 working days for a low voltage generation quotation, with £80 paid for each working day late.
What could I earn from exporting in Lydney?
On the 12p export scenario, a 12-panel system in Lydney sends about 5,576 kWh a year to the grid, worth around £669. The export rates table compares what each supplier pays.
How much solar does Lydney get in December?
December is the low point: about 220 kWh from a 12-panel system in Lydney, on PVGIS data, rising to 820 kWh in July. From November to February the same system makes about 1,070 kWh in total, which is why a battery charged off-peak does more of the work in winter.
How Lydney compares with its neighbours
How the towns nearest Lydney compare on the same PVGIS settings, closest first.
| Town | kWh per kWp a year | vs Lydney |
|---|---|---|
| Lydney | 1,024 | this town |
| Cinderford | 997 | −27 kWh |
| Cam | 998 | −26 kWh |
| Thornbury | 1,024 | level |
| Dursley | 991 | −33 kWh |
| Chepstow | 1,032 | +8 kWh |
| Monmouth | 983 | −41 kWh |
PVGIS v5.2 for each town centroid, identical assumptions throughout. A few kWh either way is weather-year noise; a spread beyond about 30 kWh per kWp is real geography.
