Connecting solar to the Somercotes and Swanwick network
Somercotes and Swanwick is served by National Grid Electricity Distribution (NGED): the town's centre falls inside its East Midlands licence area on NESO's boundary map.
Most home systems stay within 3.68kW per phase of inverter output, which puts them on G98, a notification to NGED within 28 days of switch-on. Panel count does not decide it; the inverter and any battery do.
A bigger inverter or battery output needs a G99 application in advance. 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 Somercotes and Swanwick
A heat pump in Somercotes and Swanwick
Solar and a heat pump pull in opposite directions through the year: Somercotes and Swanwick's roofs make 1,020 kWh from November to February on a 12-panel system, and 2,930 kWh from May to August. The heating season leans on the grid, so off-peak rates do the heavy lifting.
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 Somercotes and Swanwick
A 12-panel roof in Somercotes and Swanwick makes about 770 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.

Solar in Somercotes and Swanwick: your questions answered
What could a roof in Somercotes and Swanwick generate?
PVGIS puts a roof in Somercotes and Swanwick at 965 kWh per kWp a year, 2.64 peak sun hours a day averaged across the seasons. A 12-panel, 6.36 kWp system makes about 6,140 kWh a year, most of it between April and September.

Do I need permission from the DNO for solar in Somercotes and Swanwick?
Usually not in advance. NGED, the network operator for Somercotes and Swanwick, only needs a G98 notification within 28 days of commissioning for systems up to 3.68kW per phase. Bigger inverter or battery outputs need G99 approval first. NGED's guaranteed standards give 45 working days for a low voltage generation quotation, with £80 paid for each working day late. "See our DNO explainer.
How much can I earn from exporting solar in Somercotes and Swanwick?
With typical use and no battery, a 12-panel system in Somercotes and Swanwick exports about 5,201 kWh a year. At 12p per kWh that is roughly £624; a supplier paying more, or a battery that keeps more for the evening, changes the figure. See the export rates table.
Do solar panels work in winter in Somercotes and Swanwick?
Yes, at a lower level. PVGIS gives Somercotes and Swanwick 32.5 kWh per kWp in December and 34.5 in January, so a 12-panel system makes about 210 kWh and 220 kWh in those months, against 770 kWh in May. Winter output mostly covers daytime use rather than exporting.
