How Whitnash compares
Small towns rarely get published solar figures, so here are the numbers for Whitnash. It is one of 19 Warwickshire towns we track, and it ranks 7th of 19 for solar yield, a town of 9,125 people in the House of Commons Library settlement data. PVGIS gives its roofs 999 kWh per kWp a year, 2.74 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £897 of year one benefit, £247 of it from your own generation and £650 from export at 12p.
These are starting numbers, not a quote. The calculator below opens on Whitnash'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.
Warwick is the planning authority covering Whitnash, 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 Whitnash
On NESO's licence-area map, Whitnash is in East Midlands, which National Grid Electricity Distribution (NGED) operates. That makes NGED the network operator for any system fitted here.
Most home systems stay within 3.68kW per phase of inverter output, which puts them on G98, a notification to NGED 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. 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 Whitnash
A heat pump in Whitnash
A heat pump does most of its work from November to February. Over those four months, 12 panels in Whitnash make about 1,080 kWh, against 3,010 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 Whitnash
From April to September, 68% of a Whitnash roof's yearly output arrives, peaking at about 780 kWh in July 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.
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 Whitnash
What does a solar panel system produce in Whitnash?
Each kWp of panels in Whitnash makes 999 kWh a year on PVGIS figures, so a typical 12-panel system produces around 6,350 kWh, from about 220 kWh in December up to 780 kWh in July.
How much are solar panels in Whitnash?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in Whitnash before a battery. What Whitnash changes is the return, about 6,350 kWh a year from that system, and your design call prices your actual roof.
Would a system in Whitnash need approval from the network operator?
Whitnash is on National Grid Electricity Distribution's network (East Midlands licence area). Systems up to 3.68kW per phase of inverter output follow G98: NGED is notified within 28 days of commissioning, with no approval needed first. Anything larger needs a G99 application before installation. NGED's guaranteed standards give 45 working days for a low voltage generation quotation, with £80 paid for each working day late. Our G98 vs G99 guide explains both routes.
How much can I earn from exporting solar in Whitnash?
With typical use and no battery, a 12-panel system in Whitnash exports about 5,417 kWh a year. At 12p per kWh that is roughly £650; 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 Whitnash in winter?
It works, but the year is lopsided. 68% of a Whitnash roof's output lands between April and September; the four months from November to February give about 1,080 kWh on a 12-panel system. Payback is worked out on the whole year, not the winter.
How Whitnash compares with its neighbours
The six closest towns we publish, run through the identical PVGIS query as Whitnash.

| Southam | 1,005 | +6 kWh |
| Stratford-upon-Avon | 1,015 | +16 kWh |
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.
