How Amersham compares
Small towns rarely get published solar figures, so here are the numbers for Amersham. It is one of 19 Buckinghamshire towns we track, and it ranks joint 13th of 19 for solar yield, a town of 17,958 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,009 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 £905 of year one benefit, £247 of it from your own generation and £658 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Amersham'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.
Amersham sits within Buckinghamshire, 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 Amersham network
Amersham is served by UK Power Networks: the town's centre falls inside its East England licence area on NESO's boundary map.
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: UK Power Networks is notified within 28 days of commissioning and nothing has to be approved first.
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.

Heat pumps and EV charging in Amersham
A heat pump in Amersham
Solar and a heat pump pull in opposite directions through the year: Amersham's roofs make 1,100 kWh from November to February on a 12-panel system, and 3,020 kWh from May to August. The heating season leans on the grid, so off-peak rates do the heavy lifting.
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 Amersham
A 12-panel roof in Amersham makes about 780 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.

Solar in Amersham: your questions answered
What could a roof in Amersham generate?
PVGIS puts a roof in Amersham at 1,009 kWh per kWp a year, 2.77 peak sun hours a day averaged across the seasons. A 12-panel, 6.36 kWp system makes about 6,420 kWh a year, most of it between April and September.
What would 12 solar panels cost in Amersham?
£6,360 for 12 panels (6.36 kWp), the same as in every other place we cover, because solar is priced at £1,000 per kWp installed rather than by area. A battery adds its own installed price on top. Where Amersham differs is output: about 6,420 kWh a year from that system.
Do I need permission from the DNO for solar in Amersham?
Usually not in advance. UK Power Networks, the network operator for Amersham, 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 would export pay on a system in Amersham?
It is exported. With typical use and no battery, about 5,481 kWh of the 6,420 kWh a 12-panel system makes in Amersham goes to the grid, around £658 a year at 12p. A battery keeps more of it for the evening; the export rates table shows what suppliers pay.
Do solar panels work in winter in Amersham?
Yes, at a lower level. PVGIS gives Amersham 35.3 kWh per kWp in December and 39.1 in January, so a 12-panel system makes about 220 kWh and 250 kWh in those months, against 780 kWh in July. Winter output mostly covers daytime use rather than exporting.
How Amersham compares with its neighbours
How the towns nearest Amersham compare on the same PVGIS settings, closest first.
| Town | kWh per kWp a year | vs Amersham |
|---|---|---|
| Amersham | 1,009 | this town |
| Chesham | 1,009 | level |
| Chorleywood | 1,011 | +2 kWh |
| Hazlemere | 1,011 | +2 kWh |
| Beaconsfield | 1,011 | +2 kWh |
| Chalfont St Peter | 1,014 | +5 kWh |
| Prestwood and Great Missenden | 1,002 | −7 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.
