How Brockworth compares
Small towns rarely get published solar figures, so here are the numbers for Brockworth. It is one of 24 Gloucestershire towns we track, and it ranks 21st of 24 for solar yield, a town of 13,964 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.
These are starting numbers, not a quote. The calculator below opens on Brockworth's own PVGIS figure; change the panels, the battery or the export rate and it reruns. The design call replaces every assumption with your roof and your bills.
Any planning application in Brockworth sits with Tewkesbury, 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 Brockworth's own coordinates (51.84516, -2.16396), 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.
The network operator for Brockworth
The distribution network operator (DNO) for Brockworth is National Grid Electricity Distribution (NGED), which runs the West 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.
Above that, G99 means applying before the work is booked. NGED's guaranteed standards give 45 working days for a low voltage generation quotation, with £80 paid for each working day late.

Adding a heat pump or an EV charger in Brockworth
A heat pump in Brockworth
Heating demand peaks when solar is weakest. In Brockworth, a 12-panel system makes about 210 kWh in December and 230 kWh in January, a fraction of its 780 kWh in July, which is why a heat pump here is costed on its tariff first.
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 Brockworth
Brockworth's July output, about 780 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).

Brockworth solar questions
How much electricity do solar panels make in Brockworth?
About 6,300 kWh a year from 12 panels (6.36 kWp), on PVGIS satellite data for Brockworth: 990 kWh per kWp, or 2.71 peak sun hours a day on average. July is the strongest month, at about 780 kWh.
Is solar more expensive in Brockworth?
Prices on this site are the same everywhere: £1,000 per kWp installed, which puts a 12-panel system at £6,360 in Brockworth, and a Duracell Dura16 installed with solar at £4,450 on top. The local part is generation, about 6,300 kWh a year here, which is what drives payback.
Which DNO covers Brockworth, and what does it need from me?
National Grid Electricity Distribution (NGED) covers Brockworth. A home system of up to 3.68kW per phase is notified to NGED within 28 days of commissioning under G98, and nothing waits on approval. Larger outputs need a G99 application before work starts. NGED's guaranteed standards give 45 working days for a low voltage generation quotation, with £80 paid for each working day late.
What could I earn from exporting in Brockworth?
On the 12p export scenario, a 12-panel system in Brockworth sends about 5,360 kWh a year to the grid, worth around £643. The export rates table compares what each supplier pays.
How much solar does Brockworth get in December?
December is the low point: about 210 kWh from a 12-panel system in Brockworth, on PVGIS data, rising to 780 kWh in July. From November to February the same system makes about 1,030 kWh in total, which is why a battery charged off-peak does more of the work in winter.
How Brockworth 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 Brockworth |
|---|---|---|
| Brockworth | 990 | this town |
| Gloucester | 980 | −10 kWh |
| Innsworth | 983 | −7 kWh |
| Cheltenham | 991 | +1 kWh |
| Quedgeley and Hardwicke | 999 | +9 kWh |
| Stroud | 998 | +8 kWh |
| Bishop's Cleeve | 987 | −3 kWh |
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.
