How Gillingham (Dorset) compares
Small towns rarely get published solar figures, so here are the numbers for Gillingham (Dorset). It is one of 15 Dorset towns we track, and it ranks 15th of 15 for solar yield, a town of 11,379 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,035 kWh per kWp a year, 2.84 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £925 of year one benefit, £247 of it from your own generation and £678 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Gillingham (Dorset)'s own yield, and prices a 12 panel system at £6,360 installed before any battery. Your free design call reworks every number for your actual roof, its shading and your usage.
Dorset is the planning authority covering Gillingham (Dorset), which the House of Commons Library classes 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.

Who runs the grid in Gillingham (Dorset)
Gillingham (Dorset) 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.
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: SSEN is notified within 28 days of commissioning and nothing has to be approved first.
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.

Heat pumps and EV charging in Gillingham (Dorset)
A heat pump in Gillingham (Dorset)
A heat pump does most of its work from November to February. Over those four months, 12 panels in Gillingham (Dorset) make about 1,140 kWh, against 3,090 kWh from May to August, so winter heating runs mostly on grid electricity and the tariff matters more 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 Gillingham (Dorset)
From April to September, 68% of a Gillingham (Dorset) roof's yearly output arrives, peaking at about 800 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.
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).

Gillingham (Dorset) solar questions
What does a solar panel system produce in Gillingham (Dorset)?
Each kWp of panels in Gillingham (Dorset) makes 1,035 kWh a year on PVGIS figures, so a typical 12-panel system produces around 6,580 kWh, from about 230 kWh in December up to 800 kWh in May.
How much are solar panels in Gillingham (Dorset)?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in Gillingham (Dorset) before a battery. What Gillingham (Dorset) changes is the return, about 6,580 kWh a year from that system, and your design call prices your actual roof.
Would a system in Gillingham (Dorset) need approval from the network operator?
Gillingham (Dorset) is on Scottish and Southern Electricity Networks' network (Southern England licence area). Systems up to 3.68kW per phase of inverter output follow G98: SSEN is notified within 28 days of commissioning, with no approval needed first. Anything larger needs a G99 application before installation. 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. Our G98 vs G99 guide explains both routes.
How much can I earn from exporting solar in Gillingham (Dorset)?
With typical use and no battery, a 12-panel system in Gillingham (Dorset) exports about 5,646 kWh a year. At 12p per kWh that is roughly £678; a supplier paying more, or a battery that keeps more for the evening, changes the figure. See the export rates table.
Is solar worth it in Gillingham (Dorset) in winter?
It works, but the year is lopsided. 68% of a Gillingham (Dorset) roof's output lands between April and September; the four months from November to February give about 1,140 kWh on a 12-panel system. Payback is worked out on the whole year, not the winter.
