How Glastonbury compares
Small towns rarely get published solar figures, so here are the numbers for Glastonbury. It is one of 21 Somerset towns we track, and it ranks 7th of 21 for solar yield, a town of 8,443 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,033 kWh per kWp a year, 2.83 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £923 of year one benefit, £247 of it from your own generation and £676 from export at 12p.
These are starting numbers, not a quote. The calculator below opens on Glastonbury'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.
Glastonbury sits within Somerset, its local planning authority, and the House of Commons Library classes it as a 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.

Generation is modelled from PVGIS satellite data for Glastonbury's own coordinates (51.14788, -2.71734), using the same 26.32p/kWh import value and £1,000 per kWp installed pricing as every Clearline estimate; the methodology is on our help page.
Connecting solar to the Glastonbury network
On NESO's licence-area map, Glastonbury is in South West England, which National Grid Electricity Distribution (NGED) operates. That makes NGED the network operator for any system fitted here.
Below 3.68kW per phase of inverter and battery output, the G98 route applies: the installation is notified to NGED within 28 days of commissioning, with no prior approval.
A bigger inverter or battery output needs a G99 application in advance. 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 Glastonbury
A heat pump in Glastonbury
Solar and a heat pump pull in opposite directions through the year: Glastonbury's roofs make 1,130 kWh from November to February on a 12-panel system, and 3,080 kWh from May to August. The heating season leans on the grid, so off-peak rates do the heavy lifting.
Grant support in England comes from the Boiler Upgrade Scheme: £7,500 for an air source or ground source heat pump, £2,500 for air-to-air, and an extra £1,500 until March 2027 where the home is heated by oil or LPG off the gas grid (gov.uk, checked 28 September 2026).
Charging an EV in Glastonbury
A 12-panel roof in Glastonbury makes about 810 kWh in May. A typical home uses around 70 kWh of that in daylight (the calculator's typical-use settings), which leaves most of the month's output for an EV or for export.
The calculator above includes a 7.4kW smart charger from £1,100 installed. Renters and flat owners with off-street parking can claim 75% of a chargepoint's cost, up to £500 per socket, until 31 March 2027 (gov.uk, checked 28 September 2026).

Common questions about solar in Glastonbury
What could a roof in Glastonbury generate?
PVGIS puts a roof in Glastonbury at 1,033 kWh per kWp a year, 2.83 peak sun hours a day averaged across the seasons. A 12-panel, 6.36 kWp system makes about 6,570 kWh a year, most of it between April and September.
How much are solar panels in Glastonbury?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in Glastonbury before a battery. What Glastonbury changes is the return, about 6,570 kWh a year from that system, and your design call prices your actual roof.
Do I need permission from the DNO for solar in Glastonbury?
Usually not in advance. NGED, the network operator for Glastonbury, only needs a G98 notification within 28 days of commissioning for systems up to 3.68kW per phase. Bigger inverter or battery outputs need G99 approval first. NGED's guaranteed standards give 45 working days for a low voltage generation quotation, with £80 paid for each working day late. "See our DNO explainer.
How much can I earn from exporting solar in Glastonbury?
With typical use and no battery, a 12-panel system in Glastonbury exports about 5,633 kWh a year. At 12p per kWh that is roughly £676; a supplier paying more, or a battery that keeps more for the evening, changes the figure. See the export rates table.
Do solar panels work in winter in Glastonbury?
Yes, at a lower level. PVGIS gives Glastonbury 34.6 kWh per kWp in December and 40.3 in January, so a 12-panel system makes about 220 kWh and 260 kWh in those months, against 810 kWh in May. Winter output mostly covers daytime use rather than exporting.
How Glastonbury compares with its neighbours
The six closest towns we publish, run through the identical PVGIS query as Glastonbury.
| Town | kWh per kWp a year | vs Glastonbury |
|---|---|---|
| Glastonbury | 1,033 | this town |
| Street | 1,032 | −1 kWh |
| Wells | 1,015 | −18 kWh |
| Shepton Mallet | 1,015 | −18 kWh |
| Bridgwater | 1,047 | +14 kWh |
| Burnham-on-Sea | 1,049 | +16 kWh |
| Midsomer Norton | 1,005 | −28 kWh |
Same PVGIS v5.2 query for every town. Small differences are within year-to-year weather; more than about 30 kWh per kWp apart is geography.
