How Berkhamsted compares
Small towns rarely get published solar figures, so here are the numbers for Berkhamsted. It is one of 27 Hertfordshire towns we track, and it ranks 26th of 27 for solar yield, a town of 21,665 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,007 kWh per kWp a year, 2.76 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £903 of year one benefit, £247 of it from your own generation and £656 from export at 12p.
Every figure here assumes a clear, south-facing roof at 35 degrees. Yours will differ, which is what the free design call is for; until then, the calculator below tests panels, batteries and export rates on Berkhamsted's own yield.
Dacorum is the planning authority covering Berkhamsted, which the House of Commons Library classes 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.

Who runs the grid in Berkhamsted
The distribution network operator (DNO) for Berkhamsted is UK Power Networks, which runs the East England licence area.
For a typical home the paperwork is light: a system of up to 3.68kW per phase goes through G98, which means UK Power Networks is notified within 28 days of switch-on rather than asked beforehand.
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.

Beyond the panels: heating and car charging in Berkhamsted
A heat pump in Berkhamsted
A heat pump does most of its work from November to February. Over those four months, 12 panels in Berkhamsted make about 1,060 kWh, against 3,030 kWh from May to August, so winter heating runs mostly on grid electricity and the tariff matters more 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 Berkhamsted
A 12-panel roof in Berkhamsted makes about 790 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.
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 in Berkhamsted: your questions answered
What does a solar panel system produce in Berkhamsted?
Each kWp of panels in Berkhamsted makes 1,007 kWh a year on PVGIS figures, so a typical 12-panel system produces around 6,400 kWh, from about 210 kWh in December up to 790 kWh in July.
What would 12 solar panels cost in Berkhamsted?
£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 Berkhamsted differs is output: about 6,400 kWh a year from that system.
Would a system in Berkhamsted need approval from the network operator?
Berkhamsted is on UK Power Networks' network (East England licence area). Systems up to 3.68kW per phase of inverter output follow G98: UK Power Networks is notified within 28 days of commissioning, with no approval needed first. Anything larger needs a G99 application before installation. 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. Our G98 vs G99 guide explains both routes.
How much would export pay on a system in Berkhamsted?
It is exported. With typical use and no battery, about 5,468 kWh of the 6,400 kWh a 12-panel system makes in Berkhamsted goes to the grid, around £656 a year at 12p. A battery keeps more of it for the evening; the export rates table shows what suppliers pay.
Is solar worth it in Berkhamsted in winter?
It works, but the year is lopsided. 68% of a Berkhamsted roof's output lands between April and September; the four months from November to February give about 1,060 kWh on a 12-panel system. Payback is worked out on the whole year, not the winter.
How Berkhamsted compares with its neighbours
How the towns nearest Berkhamsted compare on the same PVGIS settings, closest first.
| Town | kWh per kWp a year | vs Berkhamsted |

| Berkhamsted | 1,007 | this town |
| Chesham | 1,009 | +2 kWh |
| Tring | 1,005 | −2 kWh |
| Hemel Hempstead | 1,016 | +9 kWh |
| Amersham | 1,009 | +2 kWh |
| Abbots Langley and Kings Langley | 1,016 | +9 kWh |
| Wendover | 1,000 | −7 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.
