How Salisbury compares
Among the places we publish figures for, Salisbury is one of 20 Wiltshire towns we track, and it ranks 1st of 20 for solar yield. It is a medium town in the House of Commons Library classification, with 49,217 residents, and its roofs see 2.89 peak sun hours a day across the year. That drives the standard 12 panel model to 6,716 kWh of generation, of which around 5,779 kWh is exported at 12p for £694 a year, with £247 saved on electricity you would otherwise buy at 26.32p.
Every figure here assumes a clear, south-facing roof at 35 degrees. Yours will differ, which is what the free design call is for; until then, the calculator below tests panels, batteries and export rates on Salisbury's own yield.
Salisbury sits within Wiltshire, its local planning authority, and the House of Commons Library classes it as a medium 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.

Connecting solar to the Salisbury network
Salisbury is served by Scottish and Southern Electricity Networks (SSEN): the town's centre falls inside its Southern England licence area on NESO's boundary map.
Most home systems stay within 3.68kW per phase of inverter output, which puts them on G98, a notification to SSEN within 28 days of switch-on. Panel count does not decide it; the inverter and any battery do.
A bigger inverter or battery output needs a G99 application in advance. SSEN says it can take up to 45 working days to issue a quotation for a generation connection above 3.68kW per phase and up to 50kW.

Beyond the panels: heating and car charging in Salisbury
A heat pump in Salisbury
Solar and a heat pump pull in opposite directions through the year: Salisbury's roofs make 1,160 kWh from November to February on a 12-panel system, and 3,140 kWh from May to August. The heating season leans on the grid, so off-peak rates do the heavy lifting.
In England, the Boiler Upgrade Scheme pays £7,500 towards an air source or ground source heat pump and £2,500 towards an air-to-air one, with £1,500 more until March 2027 for homes heated by oil or LPG with no mains gas (gov.uk, checked 28 September 2026).
Charging an EV in Salisbury
From April to September, 67% of a Salisbury roof's yearly output arrives, peaking at about 810 kWh in May on 12 panels. A car parked at home in daylight can soak up what the house, at around 70 kWh of daytime use that month, cannot.
If you rent, or own a flat, and have private off-street parking, the government chargepoint grant covers 75% of the cost, capped at £500 a socket, until 31 March 2027 (gov.uk, checked 28 September 2026). The calculator above prices a 7.4kW smart charger from £1,100 installed.

Common questions about solar in Salisbury
What could a roof in Salisbury generate?
PVGIS puts a roof in Salisbury at 1,056 kWh per kWp a year, 2.89 peak sun hours a day averaged across the seasons. A 12-panel, 6.36 kWp system makes about 6,720 kWh a year, most of it between April and September.
How much are solar panels in Salisbury?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in Salisbury before a battery. What Salisbury changes is the return, about 6,720 kWh a year from that system, and your design call prices your actual roof.
Do I need permission from the DNO for solar in Salisbury?
Usually not in advance. SSEN, the network operator for Salisbury, 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. SSEN says it can take up to 45 working days to issue a quotation for a generation connection above 3.68kW per phase and up to 50kW. "See our DNO explainer.
How much can I earn from exporting solar in Salisbury?
With typical use and no battery, a 12-panel system in Salisbury exports about 5,779 kWh a year. At 12p per kWh that is roughly £694; 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 Salisbury?
Yes, at a lower level. PVGIS gives Salisbury 37.1 kWh per kWp in December and 41.1 in January, so a 12-panel system makes about 240 kWh and 260 kWh in those months, against 810 kWh in May. Winter output mostly covers daytime use rather than exporting.
How Salisbury compares with its neighbours
Same satellite dataset, same assumptions, so the differences are real geography rather than modelling noise.
| Town | kWh per kWp a year | vs Salisbury |
|---|---|---|
| Salisbury | 1,056 | this town |
| Amesbury | 1,044 | −12 kWh |
| Durrington and Bulford | 1,045 | −11 kWh |
| Tidworth | 1,044 | −12 kWh |
| Verwood | 1,082 | +26 kWh |
| Romsey | 1,063 | +7 kWh |
| Ringwood | 1,125 | +69 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.
