How Sandown compares
Small towns rarely get published solar figures, so here are the numbers for Sandown. It is one of 45 Hampshire towns we track, and it ranks joint 4th of 45 for solar yield, a town of 11,856 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,138 kWh per kWp a year, 3.12 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £1,003 of year one benefit, £247 of it from your own generation and £756 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Sandown'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.
Sandown sits within Isle of Wight, 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 Sandown network
Scottish and Southern Electricity Networks (SSEN) owns and runs the local electricity network in Sandown, 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.
A bigger inverter or battery output needs a G99 application in advance. 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 Sandown
A heat pump in Sandown
Solar and a heat pump pull in opposite directions through the year: Sandown's roofs make 1,210 kWh from November to February on a 12-panel system, and 3,450 kWh from May to August. The heating season leans on the grid, so off-peak rates do the heavy lifting.
The Boiler Upgrade Scheme, open in England and Wales, takes £7,500 off an air source or ground source heat pump, or £2,500 off an air-to-air unit. Homes on oil or LPG with no mains gas get £1,500 more until March 2027 (gov.uk, checked 28 September 2026).
Charging an EV in Sandown
A 12-panel roof in Sandown makes about 900 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.

Sandown solar questions
What could a roof in Sandown generate?
PVGIS puts a roof in Sandown at 1,138 kWh per kWp a year, 3.12 peak sun hours a day averaged across the seasons. A 12-panel, 6.36 kWp system makes about 7,240 kWh a year, most of it between April and September.
How much are solar panels in Sandown?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in Sandown before a battery. What Sandown changes is the return, about 7,240 kWh a year from that system, and your design call prices your actual roof.
Do I need permission from the DNO for solar in Sandown?
Usually not in advance. SSEN, the network operator for Sandown, 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. 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. "See our DNO explainer.
How much can I earn from exporting solar in Sandown?
With typical use and no battery, a 12-panel system in Sandown exports about 6,301 kWh a year. At 12p per kWh that is roughly £756; 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 Sandown?
Yes, at a lower level. PVGIS gives Sandown 39.7 kWh per kWp in December and 42.2 in January, so a 12-panel system makes about 250 kWh and 270 kWh in those months, against 900 kWh in July. Winter output mostly covers daytime use rather than exporting.
How Sandown compares with its neighbours
How the towns nearest Sandown compare on the same PVGIS settings, closest first.

| Shanklin | 1,138 | level |
| Ryde | 1,136 | −2 kWh |
| Newport (Isle of Wight) | 1,150 | +12 kWh |

| Cowes | 1,125 | −13 kWh |
| Gosport | 1,116 | −22 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.
