Against Great Britain as a whole: Didcot makes 1,040 kWh per kWp a year, and the mean of our 85 county PVGIS estimates (our GB average) is 925, so Didcot is 12% above it.
How Didcot compares
Among the places we publish figures for, Didcot is one of 20 Berkshire 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 37,233 residents, and its roofs see 2.85 peak sun hours a day across the year. That drives the standard 12 panel model to 6,614 kWh of generation, of which around 5,678 kWh is exported at 12p for £681 a year, with £247 saved on electricity you would otherwise buy at 26.32p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Didcot'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.
Planning applications here go through South Oxfordshire; nationally, the House of Commons Library classes Didcot 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.

SSEN and your Didcot connection
The distribution network operator (DNO) for Didcot is Scottish and Southern Electricity Networks (SSEN), which runs the Southern England licence area.
G98 is the simple route. If the inverter, plus any battery, stays at or under 3.68kW per phase, SSEN only has to be told within 28 days after the system is commissioned.
Larger systems go through G99 instead, applied for before installation. On timing: 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 Didcot
A heat pump in Didcot
In December, the darkest month here, 12 panels in Didcot make about 230 kWh. That is when a heat pump runs hardest, so its running cost in Didcot comes down to the tariff and the flow temperature rather than the roof.
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 Didcot
Summer is where a car earns its place. In July, 12 panels in Didcot make about 810 kWh, against roughly 70 kWh a typical home uses in daylight that month on our calculator's typical-use settings, so there is surplus a smart charger can put into the car instead of exporting it.
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.

Didcot solar questions
How much energy would 12 solar panels make in Didcot?
Didcot averages 2.85 peak sun hours a day, which PVGIS turns into 1,040 kWh per kWp a year. On a 12-panel, 6.36 kWp roof that is about 6,610 kWh, 67% of it between April and September.
What does a typical solar system cost in Didcot?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Didcot, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 6,610 kWh a year. The final figure comes from your roof on the design call.
Who is the network operator in Didcot, and do I need a G99 application?
The operator is Scottish and Southern Electricity Networks (SSEN). Most home systems use the G98 route, a notification within 28 days of switch-on for up to 3.68kW per phase, so nothing waits on the network. Above that, G99 applies and has to be granted 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. Your design call checks which route yours needs.
What happens to the solar I do not use in Didcot?
Around £681 a year at 12p per kWh, for the roughly 5,678 kWh a 12-panel system in Didcot exports with typical use. Rates vary by supplier and some need their own tariff; the export rates table is dated and sourced.
How does solar perform in Didcot in the winter months?
December is the weakest month in Didcot: about 230 kWh from 12 panels, against 810 kWh in July. The panels still generate on bright winter days; they just cover a smaller share of what the house uses.

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.

How to size a solar and battery system, properly
Usage, storage, connection, array. Four decisions, and the order between them matters.
