Against Great Britain as a whole: Southam makes 1,005 kWh per kWp a year, and the mean of our 85 county PVGIS estimates (our GB average) is 925, so Southam is 9% above it.
How Southam compares
Small towns rarely get published solar figures, so here are the numbers for Southam. It is one of 19 Warwickshire towns we track, and it ranks 2nd of 19 for solar yield, a town of 9,234 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,005 kWh per kWp a year, 2.75 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £902 of year one benefit, £247 of it from your own generation and £655 from export at 12p.
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 Southam's own yield.
Any planning application in Southam sits with Stratford-on-Avon, 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 Southam connection
National Grid Electricity Distribution (NGED) owns and runs the local electricity network in Southam, as part of its 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.

Beyond the panels: heating and car charging in Southam
A heat pump in Southam
Heating demand peaks when solar is weakest. In Southam, a 12-panel system makes about 220 kWh in December and 240 kWh in January, a fraction of its 790 kWh in July, which is why a heat pump here is costed on its tariff first.
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 Southam
Summer is where a car earns its place. In July, 12 panels in Southam make about 790 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.
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 Southam
How much electricity do solar panels make in Southam?
About 6,390 kWh a year from 12 panels (6.36 kWp), on PVGIS satellite data for Southam: 1,005 kWh per kWp, or 2.75 peak sun hours a day on average. July is the strongest month, at about 790 kWh.
What does a typical solar system cost in Southam?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Southam, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 6,390 kWh a year. The final figure comes from your roof on the design call.
Which DNO covers Southam, and what does it need from me?
National Grid Electricity Distribution (NGED) covers Southam. 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 happens to the solar I do not use in Southam?
Around £655 a year at 12p per kWh, for the roughly 5,455 kWh a 12-panel system in Southam exports with typical use. Rates vary by supplier and some need their own tariff; the export rates table is dated and sourced.
How much solar does Southam get in December?
December is the low point: about 220 kWh from a 12-panel system in Southam, on PVGIS data, rising to 790 kWh in July. From November to February the same system makes about 1,080 kWh in total, which is why a battery charged off-peak does more of the work in winter.
How Southam 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 Southam |
|---|---|---|
| Southam | 1,005 | this town |
| Whitnash | 999 | −6 kWh |
| Royal Leamington Spa | 1,000 | −5 kWh |
| Warwick | 1,000 | −5 kWh |
| Daventry | 1,012 | +7 kWh |
| Wellesbourne | 1,003 | −2 kWh |
| Kenilworth | 998 | −7 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.
