How Potters Bar compares
Small towns rarely get published solar figures, so here are the numbers for Potters Bar. It is one of 23 Middlesex towns we track, and it ranks joint 5th of 23 for solar yield, a town of 23,545 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,026 kWh per kWp a year, 2.81 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £918 of year one benefit, £247 of it from your own generation and £671 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Potters Bar'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 Potters Bar sits with Hertsmere, 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.

The network operator for Potters Bar
UK Power Networks owns and runs the local electricity network in Potters Bar, as part of its 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.
Larger systems go through G99 instead, applied for before installation. On timing: 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 Potters Bar
A heat pump in Potters Bar
Heating demand peaks when solar is weakest. In Potters Bar, a 12-panel system makes about 240 kWh in December and 260 kWh in January, a fraction of its 800 kWh in July, which is why a heat pump here is costed on its tariff first.
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 Potters Bar
Summer is where a car earns its place. In July, 12 panels in Potters Bar make about 800 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.
If you rent, or own a flat, and have private off-street parking, the government chargepoint grant covers 75% of the cost, capped at £500 a socket, until 31 March 2027 (gov.uk, checked 28 September 2026). The calculator above prices a 7.4kW smart charger from £1,100 installed.

Solar in Potters Bar: your questions answered
How much energy would 12 solar panels make in Potters Bar?
Potters Bar averages 2.81 peak sun hours a day, which PVGIS turns into 1,026 kWh per kWp a year. On a 12-panel, 6.36 kWp roof that is about 6,530 kWh, 67% of it between April and September.
What does a typical solar system cost in Potters Bar?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Potters Bar, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 6,530 kWh a year. The final figure comes from your roof on the design call.
Who is the network operator in Potters Bar, and do I need a G99 application?
The operator is UK Power Networks. 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. 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. Your design call checks which route yours needs.
What happens to the solar I do not use in Potters Bar?
Around £671 a year at 12p per kWh, for the roughly 5,589 kWh a 12-panel system in Potters Bar 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 Potters Bar in the winter months?
December is the weakest month in Potters Bar: about 240 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.
