Against Great Britain as a whole: Bushey makes 1,024 kWh per kWp a year, and the mean of our 85 county PVGIS estimates (our GB average) is 925, so Bushey is 11% above it.
How Bushey compares
Among the places we publish figures for, Bushey is one of 27 Hertfordshire towns we track, and it ranks joint 5th of 27 for solar yield. It is a medium town in the House of Commons Library classification, with 29,226 residents, and its roofs see 2.80 peak sun hours a day across the year. That drives the standard 12 panel model to 6,513 kWh of generation, of which around 5,576 kWh is exported at 12p for £669 a year, with £247 saved on electricity you would otherwise buy at 26.32p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Bushey'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.
Hertsmere is the planning authority covering Bushey, which the House of Commons Library classes as a medium 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 Bushey
The distribution network operator (DNO) for Bushey is UK Power Networks, which runs the East England licence area.
G98 is the simple route. If the inverter, plus any battery, stays at or under 3.68kW per phase, UK Power Networks only has to be told within 28 days after the system is commissioned.
A bigger inverter or battery output needs a G99 application in advance. 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 Bushey
A heat pump in Bushey
A heat pump does most of its work from November to February. Over those four months, 12 panels in Bushey make about 1,140 kWh, against 3,050 kWh from May to August, so winter heating runs mostly on grid electricity and the tariff matters more than the roof.
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 Bushey
From April to September, 67% of a Bushey roof's yearly output arrives, peaking at about 790 kWh in July on 12 panels. A car parked at home in daylight can soak up what the house, at around 70 kWh of daytime use that month, cannot.
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).

Bushey solar questions
What does a solar panel system produce in Bushey?
Each kWp of panels in Bushey makes 1,024 kWh a year on PVGIS figures, so a typical 12-panel system produces around 6,510 kWh, from about 240 kWh in December up to 790 kWh in July.
What would 12 solar panels cost in Bushey?
£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 Bushey differs is output: about 6,510 kWh a year from that system.
Would a system in Bushey need approval from the network operator?
Bushey 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 Bushey?
It is exported. With typical use and no battery, about 5,576 kWh of the 6,510 kWh a 12-panel system makes in Bushey goes to the grid, around £669 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 Bushey in winter?
It works, but the year is lopsided. 67% of a Bushey roof's output lands between April and September; the four months from November to February give about 1,140 kWh on a 12-panel system. Payback is worked out on the whole year, not the winter.
How Bushey 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 Bushey |
|---|---|---|
| Bushey | 1,024 | this town |
| Watford | 1,013 | −11 kWh |
| Radlett | 1,018 | −6 kWh |
| Borehamwood | 1,015 | −9 kWh |
| Harrow | 1,026 | +2 kWh |
| Rickmansworth | 1,019 | −5 kWh |
| Abbots Langley and Kings Langley | 1,016 | −8 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.
