How Frome compares
Among the places we publish figures for, Frome is one of 21 Somerset towns we track, and it ranks joint 18th of 21 for solar yield. It is a medium town in the House of Commons Library classification, with 28,302 residents, and its roofs see 2.76 peak sun hours a day across the year. That drives the standard 12 panel model to 6,411 kWh of generation, of which around 5,474 kWh is exported at 12p for £657 a year, with £247 saved on electricity you would otherwise buy at 26.32p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Frome'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 Frome sits with Somerset, and its official House of Commons Library settlement class is 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 Frome's own coordinates (51.23193, -2.31747), 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 Frome
On NESO's licence-area map, Frome is in Southern England, which Scottish and Southern Electricity Networks (SSEN) operates. That makes SSEN the network operator for any system fitted here.
Below 3.68kW per phase of inverter and battery output, the G98 route applies: the installation is notified to SSEN within 28 days of commissioning, with no prior approval.
Above that, G99 means applying before the work is booked. SSEN says it can take up to 45 working days to issue a quotation for a generation connection above 3.68kW per phase and up to 50kW.

Heat pumps and EV charging in Frome
A heat pump in Frome
In December, the darkest month here, 12 panels in Frome make about 210 kWh. That is when a heat pump runs hardest, so its running cost in Frome comes down to the tariff and the flow temperature rather 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 Frome
Frome's July output, about 800 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.
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.

Solar in Frome: your questions answered
How much electricity do solar panels make in Frome?
About 6,410 kWh a year from 12 panels (6.36 kWp), on PVGIS satellite data for Frome: 1,008 kWh per kWp, or 2.76 peak sun hours a day on average. July is the strongest month, at about 800 kWh.
Is solar more expensive in Frome?
Prices on this site are the same everywhere: £1,000 per kWp installed, which puts a 12-panel system at £6,360 in Frome, and a Duracell Dura16 installed with solar at £4,450 on top. The local part is generation, about 6,410 kWh a year here, which is what drives payback.
Which DNO covers Frome, and what does it need from me?
Scottish and Southern Electricity Networks (SSEN) covers Frome. A home system of up to 3.68kW per phase is notified to SSEN within 28 days of commissioning under G98, and nothing waits on approval. Larger outputs need a G99 application before work starts. SSEN says it can take up to 45 working days to issue a quotation for a generation connection above 3.68kW per phase and up to 50kW.
What could I earn from exporting in Frome?
On the 12p export scenario, a 12-panel system in Frome sends about 5,474 kWh a year to the grid, worth around £657. The export rates table compares what each supplier pays.
How much solar does Frome get in December?
December is the low point: about 210 kWh from a 12-panel system in Frome, on PVGIS data, rising to 800 kWh in July. From November to February the same system makes about 1,070 kWh in total, which is why a battery charged off-peak does more of the work in winter.
How Frome compares with its neighbours
The six closest towns we publish, run through the identical PVGIS query as Frome.
| Town | kWh per kWp a year | vs Frome |
|---|---|---|
| Frome | 1,008 | this town |
| Westbury | 1,029 | +21 kWh |
| Warminster | 1,031 | +23 kWh |
| Radstock | 1,003 | −5 kWh |
| Trowbridge | 1,022 | +14 kWh |
| Midsomer Norton | 1,005 | −3 kWh |
| Bradford-on-Avon | 1,020 | +12 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.
