Against Great Britain as a whole: Hazlemere makes 1,011 kWh per kWp a year, and the mean of our 85 county PVGIS estimates (our GB average) is 925, so Hazlemere is 9% above it.
How Hazlemere compares
Small towns rarely get published solar figures, so here are the numbers for Hazlemere. It is one of 19 Buckinghamshire towns we track, and it ranks joint 10th of 19 for solar yield, a town of 20,016 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,011 kWh per kWp a year, 2.77 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £906 of year one benefit, £247 of it from your own generation and £659 from export at 12p.
These are starting numbers, not a quote. The calculator below opens on Hazlemere'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 Buckinghamshire; nationally, the House of Commons Library classes Hazlemere 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 Hazlemere
Hazlemere sits in Scottish and Southern Electricity Networks' Southern England licence area, so SSEN is the network operator (DNO) any solar panels or battery here are registered with.
Below 3.68kW per phase of inverter and battery output, the G98 route applies: the installation is notified to SSEN within 28 days of commissioning, with no prior approval.
Larger systems go through G99 instead, applied for before installation. On timing: 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.

Adding a heat pump or an EV charger in Hazlemere
A heat pump in Hazlemere
In December, the darkest month here, 12 panels in Hazlemere make about 220 kWh. That is when a heat pump runs hardest, so its running cost in Hazlemere 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 Hazlemere
Summer is where a car earns its place. In July, 12 panels in Hazlemere make about 780 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.

Solar panel servicing and repair in Hazlemere
If a system in Hazlemere is underperforming, start with the guides below: repair benchmarks, service scope, and the inverter question.
Hazlemere solar questions
How much energy would 12 solar panels make in Hazlemere?
Hazlemere averages 2.77 peak sun hours a day, which PVGIS turns into 1,011 kWh per kWp a year. On a 12-panel, 6.36 kWp roof that is about 6,430 kWh, 68% of it between April and September.
What does a typical solar system cost in Hazlemere?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Hazlemere, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 6,430 kWh a year. The final figure comes from your roof on the design call.
Who is the network operator in Hazlemere, 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 happens to the solar I do not use in Hazlemere?
Around £659 a year at 12p per kWh, for the roughly 5,493 kWh a 12-panel system in Hazlemere 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 Hazlemere in the winter months?
December is the weakest month in Hazlemere: about 220 kWh from 12 panels, against 780 kWh in July. The panels still generate on bright winter days; they just cover a smaller share of what the house uses.
How Hazlemere 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 Hazlemere |
|---|---|---|
| Hazlemere | 1,011 | this town |
| High Wycombe | 1,012 | +1 kWh |
| Flackwell Heath and Wooburn Green | 1,009 | −2 kWh |
| Prestwood and Great Missenden | 1,002 | −9 kWh |
| Beaconsfield | 1,011 | level |
| Amersham | 1,009 | −2 kWh |
| Chesham | 1,009 | −2 kWh |
Each row is a PVGIS v5.2 run at that town's centre with the same settings. Treat gaps of a few kWh as noise and gaps over about 30 kWh per kWp as real differences in sunshine.
