How Hook compares
Small towns rarely get published solar figures, so here are the numbers for Hook. It is one of 45 Hampshire towns we track, and it ranks 38th of 45 for solar yield, a town of 9,718 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,036 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.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Hook'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.
Any planning application in Hook sits with Hart, and its official House of Commons Library settlement class is 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.

SSEN and your Hook connection
Scottish and Southern Electricity Networks (SSEN) owns and runs the local electricity network in Hook, 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.
Above that, G99 means applying before the work is booked. 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 Hook
A heat pump in Hook
In December, the darkest month here, 12 panels in Hook make about 230 kWh. That is when a heat pump runs hardest, so its running cost in Hook comes down to the tariff and the flow temperature rather than the roof.
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 Hook
Hook's July output, about 800 kWh from 12 panels, is several times the 70 kWh or so a typical home uses in daylight that month on our calculator's settings. Daytime charging turns that surplus into miles.
The calculator above includes a 7.4kW smart charger from £1,100 installed. Renters and flat owners with off-street parking can claim 75% of a chargepoint's cost, up to £500 per socket, until 31 March 2027 (gov.uk, checked 28 September 2026).

Solar panel servicing and repair in Hook
If a system in Hook is underperforming, start with the guides below: repair benchmarks, service scope, and the inverter question.
Hook solar questions
How much energy would 12 solar panels make in Hook?
Hook averages 2.84 peak sun hours a day, which PVGIS turns into 1,036 kWh per kWp a year. On a 12-panel, 6.36 kWp roof that is about 6,590 kWh, 68% of it between April and September.
Is solar more expensive in Hook?
Prices on this site are the same everywhere: £1,000 per kWp installed, which puts a 12-panel system at £6,360 in Hook, and a Duracell Dura16 installed with solar at £4,450 on top. The local part is generation, about 6,590 kWh a year here, which is what drives payback.
Who is the network operator in Hook, and do I need a G99 application?
The operator is Scottish and Southern Electricity Networks (SSEN). 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. 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. Your design call checks which route yours needs.
What could I earn from exporting in Hook?
On the 12p export scenario, a 12-panel system in Hook sends about 5,652 kWh a year to the grid, worth around £678. The export rates table compares what each supplier pays.
How does solar perform in Hook in the winter months?
December is the weakest month in Hook: about 230 kWh from 12 panels, against 800 kWh in July. The panels still generate on bright winter days; they just cover a smaller share of what the house uses.
How Hook 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 Hook |
|---|---|---|
| Hook | 1,036 | this town |
| Fleet | 1,023 | −13 kWh |
| Basingstoke | 1,031 | −5 kWh |
| Yateley | 1,017 | −19 kWh |
| Weybourne | 1,020 | −16 kWh |
| Farnborough | 1,022 | −14 kWh |
| Sandhurst | 1,016 | −20 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.
