Against Great Britain as a whole: Byfleet makes 1,024 kWh per kWp a year, and the mean of our 85 county PVGIS estimates (our GB average) is 925, so Byfleet is 11% above it.
How Byfleet compares
Small towns rarely get published solar figures, so here are the numbers for Byfleet. It is one of 47 Surrey towns we track, and it ranks joint 24th of 47 for solar yield, a town of 14,275 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,024 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 £916 of year one benefit, £247 of it from your own generation and £669 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Byfleet'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 Byfleet sits with Elmbridge, 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.

Generation is modelled from PVGIS satellite data for Byfleet's own coordinates (51.3496, -0.45716), using the same 26.32p/kWh import value and £1,000 per kWp installed pricing as every Clearline estimate; the methodology is on our help page.
UK Power Networks and your Byfleet connection
The distribution network operator (DNO) for Byfleet is UK Power Networks, which runs the South 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.
Above that, G99 means applying before the work is booked. 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 Byfleet
A heat pump in Byfleet
In December, the darkest month here, 12 panels in Byfleet make about 230 kWh. That is when a heat pump runs hardest, so its running cost in Byfleet comes down to the tariff and the flow temperature rather 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 Byfleet
Byfleet's July output, about 810 kWh from 12 panels, is several times the 70 kWh or so a typical home uses in daylight that month on our calculator's settings. Daytime charging turns that surplus into miles.
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).

If a system in Byfleet is underperforming, start with the guides below: repair benchmarks, service scope, and the inverter question.
Byfleet solar questions
How much energy would 12 solar panels make in Byfleet?
Byfleet averages 2.81 peak sun hours a day, which PVGIS turns into 1,024 kWh per kWp a year. On a 12-panel, 6.36 kWp roof that is about 6,510 kWh, 68% of it between April and September.
Is solar more expensive in Byfleet?
Prices on this site are the same everywhere: £1,000 per kWp installed, which puts a 12-panel system at £6,360 in Byfleet, and a Duracell Dura16 installed with solar at £4,450 on top. The local part is generation, about 6,510 kWh a year here, which is what drives payback.
Who is the network operator in Byfleet, 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 could I earn from exporting in Byfleet?
On the 12p export scenario, a 12-panel system in Byfleet sends about 5,576 kWh a year to the grid, worth around £669. The export rates table compares what each supplier pays.
How does solar perform in Byfleet in the winter months?
December is the weakest month in Byfleet: about 230 kWh from 12 panels, against 810 kWh in July. The panels still generate on bright winter days; they just cover a smaller share of what the house uses.
How Byfleet compares with its neighbours
How the towns nearest Byfleet compare on the same PVGIS settings, closest first.

| Addlestone | 1,024 | level |
| Hersham | 1,025 | +1 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.
