How Willenhall compares
Among the places we publish figures for, Willenhall is one of 44 Staffordshire towns we track, and it ranks joint 11th of 44 for solar yield. It is a medium town in the House of Commons Library classification, with 51,124 residents, and its roofs see 2.64 peak sun hours a day across the year. That drives the standard 12 panel model to 6,118 kWh of generation, of which around 5,182 kWh is exported at 12p for £622 a year, with £247 saved on electricity you would otherwise buy at 26.32p.
Every figure here assumes a clear, south-facing roof at 35 degrees. Yours will differ, which is what the free design call is for; until then, the calculator below tests panels, batteries and export rates on Willenhall's own yield.
Walsall is the planning authority covering Willenhall, 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.

Generation is modelled from PVGIS satellite data for Willenhall's own coordinates (52.59506, -2.0414), 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.
Who runs the grid in Willenhall
National Grid Electricity Distribution (NGED) owns and runs the local electricity network in Willenhall, as part of its West Midlands licence area.
What decides the paperwork is the inverter and battery output, not the number of panels. Up to 3.68kW per phase, a system follows G98: NGED is notified within 28 days of commissioning and nothing has to be approved first.
Anything bigger is a G99 case and is applied for first. NGED's guaranteed standards give 45 working days for a low voltage generation quotation, with £80 paid for each working day late.

Beyond the panels: heating and car charging in Willenhall
A heat pump in Willenhall
A heat pump does most of its work from November to February. Over those four months, 12 panels in Willenhall make about 1,030 kWh, against 2,900 kWh from May to August, so winter heating runs mostly on grid electricity and the tariff matters more than the roof.
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 Willenhall
A 12-panel roof in Willenhall makes about 750 kWh in July. A typical home uses around 70 kWh of that in daylight (the calculator's typical-use settings), which leaves most of the month's output for an EV or for export.
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).

Common questions about solar in Willenhall
What does a solar panel system produce in Willenhall?
Each kWp of panels in Willenhall makes 962 kWh a year on PVGIS figures, so a typical 12-panel system produces around 6,120 kWh, from about 220 kWh in December up to 750 kWh in July.
How much are solar panels in Willenhall?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in Willenhall before a battery. What Willenhall changes is the return, about 6,120 kWh a year from that system, and your design call prices your actual roof.
Would a system in Willenhall need approval from the network operator?
Willenhall is on National Grid Electricity Distribution's network (West Midlands licence area). Systems up to 3.68kW per phase of inverter output follow G98: NGED is notified within 28 days of commissioning, with no approval needed first. Anything larger needs a G99 application before installation. NGED's guaranteed standards give 45 working days for a low voltage generation quotation, with £80 paid for each working day late. Our G98 vs G99 guide explains both routes.
How much can I earn from exporting solar in Willenhall?
With typical use and no battery, a 12-panel system in Willenhall exports about 5,182 kWh a year. At 12p per kWh that is roughly £622; a supplier paying more, or a battery that keeps more for the evening, changes the figure. See the export rates table.
Is solar worth it in Willenhall in winter?
It works, but the year is lopsided. 68% of a Willenhall roof's output lands between April and September; the four months from November to February give about 1,030 kWh on a 12-panel system. Payback is worked out on the whole year, not the winter.
How Willenhall 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 Willenhall |
|---|---|---|
| Willenhall | 962 | this town |
| Darlaston | 962 | level |
| Bloxwich | 958 | −4 kWh |
| Bilston | 955 | −7 kWh |
| Walsall | 966 | +4 kWh |
| Wednesbury | 962 | level |
| Wolverhampton | 948 | −14 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.
