How Whittlesey compares
Small towns rarely get published solar figures, so here are the numbers for Whittlesey. It is one of 11 Cambridgeshire towns we track, and it ranks 7th of 11 for solar yield, a town of 14,878 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.
These are starting numbers, not a quote. The calculator below opens on Whittlesey'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.
Whittlesey sits within Fenland, its local planning authority, and the House of Commons Library classes it 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.

Connecting solar to the Whittlesey network
UK Power Networks owns and runs the local electricity network in Whittlesey, as part of its East England licence area.
For a typical home the paperwork is light: a system of up to 3.68kW per phase goes through G98, which means UK Power Networks is notified within 28 days of switch-on rather than asked beforehand.
Anything bigger is a G99 case and is applied for first. Ofgem's guaranteed standard for a low voltage generation connection quotation is 45 working days, with £80 paid for each working day late, and it binds UK Power Networks as it does every network operator.

Adding a heat pump or an EV charger in Whittlesey
A heat pump in Whittlesey
Solar and a heat pump pull in opposite directions through the year: Whittlesey's roofs make 1,140 kWh from November to February on a 12-panel system, and 3,080 kWh from May to August. The heating season leans on the grid, so off-peak rates do the heavy lifting.
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 Whittlesey
From April to September, 67% of a Whittlesey 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.
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.

Whittlesey solar questions
What could a roof in Whittlesey generate?
PVGIS puts a roof in Whittlesey at 1,035 kWh per kWp a year, 2.84 peak sun hours a day averaged across the seasons. A 12-panel, 6.36 kWp system makes about 6,580 kWh a year, most of it between April and September.
How much are solar panels in Whittlesey?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in Whittlesey before a battery. What Whittlesey changes is the return, about 6,580 kWh a year from that system, and your design call prices your actual roof.
Do I need permission from the DNO for solar in Whittlesey?
Usually not in advance. UK Power Networks, the network operator for Whittlesey, 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. Ofgem's guaranteed standard for a low voltage generation connection quotation is 45 working days, with £80 paid for each working day late, and it binds UK Power Networks as it does every network operator. "See our DNO explainer.
How much can I earn from exporting solar in Whittlesey?
With typical use and no battery, a 12-panel system in Whittlesey 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.
Do solar panels work in winter in Whittlesey?
Yes, at a lower level. PVGIS gives Whittlesey 37.1 kWh per kWp in December and 38.1 in January, so a 12-panel system makes about 240 kWh and 240 kWh in those months, against 800 kWh in May. Winter output mostly covers daytime use rather than exporting.

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.
