For scale: 1,039 kWh per kWp in Somerset against 925, our GB average (the mean of our 85 county PVGIS estimates), which puts Somerset 12% above it.
How Somerset compares
Somerset ranks joint 7th of the 85 counties we track for solar yield, which puts export income near the top of the country. On the 12p scenario a 12 panel system here sends about 5,671 kWh to the grid a year on top of the £247 it saves you directly, so oversizing the array is usually the right call.
These are county-level starting numbers. A town page gives the figure for its own centroid, and your design call replaces both with your roof, its shading and your bills.
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 from PVGIS v5.2 (European Commission JRC, SARAH3), retrieved August 2026 for a representative point in Somerset (51.1499, -2.8781), assuming 1 kWp, 14% system loss, 35 degree pitch, due south. Import valued at 26.32p/kWh (Ofgem price cap average, Oct to Dec 2026); off-peak charging at 8.5p/kWh where used (a supplier's published off-peak rate, checked September 2026); export at the scenario you pick, from the dated tariff table. Prices are installed pricing, August 2026, standard installations; 530W LONGi panels at £1,000 per kWp. Estimates for illustration, not a quote: your free design call prices your actual roof.
Who runs the grid in Somerset
The centre of Somerset sits in National Grid Electricity Distribution's South West England licence area on NESO's boundary map, so NGED is the network operator (DNO) a system here is registered with.
Below 3.68kW per phase of inverter and battery output, the G98 route applies: the installation is notified to NGED within 28 days of commissioning, with no prior approval.
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.
Parts of Somerset are on a different network: some of its towns are served by SSEN. Each town page names its own operator, worked out from that town's own location.

Adding a heat pump or an EV charger in Somerset
A heat pump in Somerset
A heat pump does most of its work from November to February. Over those four months, 12 panels in Somerset make about 1,130 kWh, against 3,090 kWh from May to August, so winter heating runs mostly on grid electricity and the tariff matters more than the roof.
In England, the Boiler Upgrade Scheme pays £7,500 towards an air source or ground source heat pump and £2,500 towards an air-to-air one, with £1,500 more until March 2027 for homes heated by oil or LPG with no mains gas (gov.uk, checked 28 September 2026).
Charging an EV in Somerset
A 12-panel roof in Somerset makes about 810 kWh in May. 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.
If you rent, or own a flat, and have private off-street parking, the government chargepoint grant covers 75% of the cost, capped at £500 a socket, until 31 March 2027 (gov.uk, checked 28 September 2026). The calculator above prices a 7.4kW smart charger from £1,100 installed.

Somerset solar questions
What does a solar panel system produce in Somerset?
Each kWp of panels in Somerset makes 1,039 kWh a year on PVGIS figures, so a typical 12-panel system produces around 6,610 kWh, from about 220 kWh in December up to 810 kWh in May.
What would 12 solar panels cost in Somerset?
£6,360 for 12 panels (6.36 kWp), the same as in every other place we cover, because solar is priced at £1,000 per kWp installed rather than by area. A battery adds its own installed price on top. Where Somerset differs is output: about 6,610 kWh a year from that system.
Would a system in Somerset need approval from the network operator?
The centre of Somerset is on National Grid Electricity Distribution's network (South West England 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 would export pay on a system in Somerset?
It is exported. With typical use and no battery, about 5,671 kWh of the 6,610 kWh a 12-panel system makes in Somerset goes to the grid, around £681 a year at 12p. A battery keeps more of it for the evening; the export rates table shows what suppliers pay.
Is solar worth it in Somerset in winter?
It works, but the year is lopsided. 68% of a Somerset roof's output lands between April and September; the four months from November to February give about 1,130 kWh on a 12-panel system. Payback is worked out on the whole year, not the winter.
