Against Great Britain as a whole: Sandy makes 1,029 kWh per kWp a year, and the mean of our 85 county PVGIS estimates (our GB average) is 925, so Sandy is 11% above it.
How Sandy compares
Small towns rarely get published solar figures, so here are the numbers for Sandy. It is one of 15 Bedfordshire towns we track, and it ranks joint 1st of 15 for solar yield, a town of 11,383 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,029 kWh per kWp a year, 2.82 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £920 of year one benefit, £247 of it from your own generation and £673 from export at 12p.
These are starting numbers, not a quote. The calculator below opens on Sandy'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.
Planning applications here go through Central Bedfordshire; nationally, the House of Commons Library classes Sandy 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.

The network operator for Sandy
Sandy sits in UK Power Networks' East England licence area, so UK Power Networks is the network operator (DNO) any solar panels or battery here are registered with.
G98 is the simple route. If the inverter, plus any battery, stays at or under 3.68kW per phase, UK Power Networks 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: 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 Sandy
A heat pump in Sandy
In December, the darkest month here, 12 panels in Sandy make about 240 kWh. That is when a heat pump runs hardest, so its running cost in Sandy comes down to the tariff and the flow temperature rather 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 Sandy
Summer is where a car earns its place. In July, 12 panels in Sandy make about 790 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.
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 Sandy
How much energy would 12 solar panels make in Sandy?
Sandy averages 2.82 peak sun hours a day, which PVGIS turns into 1,029 kWh per kWp a year. On a 12-panel, 6.36 kWp roof that is about 6,540 kWh, 67% of it between April and September.
What does a typical solar system cost in Sandy?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Sandy, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 6,540 kWh a year. The final figure comes from your roof on the design call.
Who is the network operator in Sandy, and do I need a G99 application?
The operator is UK Power Networks. 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. 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. Your design call checks which route yours needs.
What happens to the solar I do not use in Sandy?
Around £673 a year at 12p per kWh, for the roughly 5,608 kWh a 12-panel system in Sandy 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 Sandy in the winter months?
December is the weakest month in Sandy: about 240 kWh from 12 panels, against 790 kWh in July. The panels still generate on bright winter days; they just cover a smaller share of what the house uses.
How Sandy 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 Sandy |
|---|---|---|
| Sandy | 1,029 | this town |
| Biggleswade | 1,029 | level |
| St Neots | 1,026 | −3 kWh |
| Shefford | 1,025 | −4 kWh |
| Bedford | 1,028 | −1 kWh |
| Wixams | 1,026 | −3 kWh |
| Stotfold | 1,022 | −7 kWh |
Same PVGIS v5.2 query for every town. Small differences are within year-to-year weather; more than about 30 kWh per kWp apart is geography.
