How Barwell compares
Small towns rarely get published solar figures, so here are the numbers for Barwell. It is one of 26 Leicestershire towns we track, and it ranks joint 12th of 26 for solar yield, a town of 9,184 people in the House of Commons Library settlement data. PVGIS gives its roofs 990 kWh per kWp a year, 2.71 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £890 of year one benefit, £247 of it from your own generation and £643 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Barwell'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 Barwell sits with Hinckley and Bosworth, 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.

NGED and your Barwell connection
The distribution network operator (DNO) for Barwell is National Grid Electricity Distribution (NGED), which runs the East Midlands licence area.
For a typical home the paperwork is light: a system of up to 3.68kW per phase goes through G98, which means NGED is notified within 28 days of switch-on rather than asked beforehand.
Larger systems go through G99 instead, applied for before installation. On timing: NGED's guaranteed standards give 45 working days for a low voltage generation quotation, with £80 paid for each working day late.

Heat pumps and EV charging in Barwell
A heat pump in Barwell
In December, the darkest month here, 12 panels in Barwell make about 220 kWh. That is when a heat pump runs hardest, so its running cost in Barwell 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 Barwell
Summer is where a car earns its place. In July, 12 panels in Barwell make about 780 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.
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.

Barwell solar questions
How much energy would 12 solar panels make in Barwell?
Barwell averages 2.71 peak sun hours a day, which PVGIS turns into 990 kWh per kWp a year. On a 12-panel, 6.36 kWp roof that is about 6,300 kWh, 68% of it between April and September.
What does a typical solar system cost in Barwell?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Barwell, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 6,300 kWh a year. The final figure comes from your roof on the design call.
Who is the network operator in Barwell, and do I need a G99 application?
The operator is National Grid Electricity Distribution (NGED). 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. NGED's guaranteed standards give 45 working days for a low voltage generation quotation, with £80 paid for each working day late. Your design call checks which route yours needs.
What happens to the solar I do not use in Barwell?
Around £643 a year at 12p per kWh, for the roughly 5,360 kWh a 12-panel system in Barwell 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 Barwell in the winter months?
December is the weakest month in Barwell: about 220 kWh from 12 panels, against 780 kWh in July. The panels still generate on bright winter days; they just cover a smaller share of what the house uses.
How Barwell 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 Barwell |
|---|---|---|
| Barwell | 990 | this town |
| Earl Shilton | 990 | level |
| Hinckley | 988 | −2 kWh |
| Enderby and Narborough | 990 | level |
| Broughton Astley | 991 | +1 kWh |
| Nuneaton | 984 | −6 kWh |
| Leicester Forest East and Kirby Muxloe | 990 | level |
Same PVGIS v5.2 query for every town. Small differences are within year-to-year weather; more than about 30 kWh per kWp apart is geography.
