How Winnersh compares
Small towns rarely get published solar figures, so here are the numbers for Winnersh. It is one of 20 Berkshire towns we track, and it ranks joint 15th of 20 for solar yield, a town of 9,344 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,017 kWh per kWp a year, 2.79 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £911 of year one benefit, £247 of it from your own generation and £664 from export at 12p.
These are starting numbers, not a quote. The calculator below opens on Winnersh'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.
Wokingham is the planning authority covering Winnersh, 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 Winnersh
Scottish and Southern Electricity Networks (SSEN) owns and runs the local electricity network in Winnersh, as part of its Southern England 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: SSEN is notified within 28 days of commissioning and nothing has to be approved first.
Anything bigger is a G99 case and is applied for 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.

Adding a heat pump or an EV charger in Winnersh
A heat pump in Winnersh
A heat pump does most of its work from November to February. Over those four months, 12 panels in Winnersh make about 1,110 kWh, against 3,050 kWh from May to August, so winter heating runs mostly on grid electricity and the tariff matters more than the roof.
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 Winnersh
A 12-panel roof in Winnersh makes about 790 kWh in July. 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.
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 Winnersh
What does a solar panel system produce in Winnersh?
Each kWp of panels in Winnersh makes 1,017 kWh a year on PVGIS figures, so a typical 12-panel system produces around 6,470 kWh, from about 230 kWh in December up to 790 kWh in July.
How much are solar panels in Winnersh?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in Winnersh before a battery. What Winnersh changes is the return, about 6,470 kWh a year from that system, and your design call prices your actual roof.
Would a system in Winnersh need approval from the network operator?
Winnersh 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 Winnersh?
With typical use and no battery, a 12-panel system in Winnersh exports about 5,531 kWh a year. At 12p per kWh that is roughly £664; 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 Winnersh in winter?
It works, but the year is lopsided. 68% of a Winnersh roof's output lands between April and September; the four months from November to February give about 1,110 kWh on a 12-panel system. Payback is worked out on the whole year, not the winter.
How Winnersh 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 Winnersh |
|---|---|---|
| Winnersh | 1,017 | this town |
| Woodley | 1,021 | +4 kWh |
| Wokingham | 1,011 | −6 kWh |
| Twyford | 1,021 | +4 kWh |
| Reading | 1,028 | +11 kWh |
| Caversham | 1,025 | +8 kWh |
| Crowthorne | 1,017 | level |
Each row is a PVGIS v5.2 run at that town's centre with the same settings. Treat gaps of a few kWh as noise and gaps over about 30 kWh per kWp as real differences in sunshine.
