How Sileby compares
Small towns rarely get published solar figures, so here are the numbers for Sileby. It is one of 26 Leicestershire towns we track, and it ranks joint 25th of 26 for solar yield, a town of 9,608 people in the House of Commons Library settlement data. PVGIS gives its roofs 978 kWh per kWp a year, 2.68 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £881 of year one benefit, £247 of it from your own generation and £634 from export at 12p.
These are starting numbers, not a quote. The calculator below opens on Sileby's own PVGIS figure; change the panels, the battery or the export rate and it reruns. The design call replaces every assumption with your roof and your bills.
Sileby sits within Charnwood, its local planning authority, and the House of Commons Library classes it as a 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.

Connecting solar to the Sileby network
On NESO's licence-area map, Sileby is in East Midlands, which National Grid Electricity Distribution (NGED) operates. That makes NGED the network operator for any system fitted here.
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.
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.

Adding a heat pump or an EV charger in Sileby
A heat pump in Sileby
Solar and a heat pump pull in opposite directions through the year: Sileby's roofs make 1,070 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 Sileby
From April to September, 68% of a Sileby roof's yearly output arrives, peaking at about 760 kWh in July on 12 panels. A car parked at home in daylight can soak up what the house, at around 70 kWh of daytime use that month, cannot.
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.

Common questions about solar in Sileby
What could a roof in Sileby generate?
PVGIS puts a roof in Sileby at 978 kWh per kWp a year, 2.68 peak sun hours a day averaged across the seasons. A 12-panel, 6.36 kWp system makes about 6,220 kWh a year, most of it between April and September.
What would 12 solar panels cost in Sileby?
£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 Sileby differs is output: about 6,220 kWh a year from that system.
Do I need permission from the DNO for solar in Sileby?
Usually not in advance. NGED, the network operator for Sileby, 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 would export pay on a system in Sileby?
It is exported. With typical use and no battery, about 5,283 kWh of the 6,220 kWh a 12-panel system makes in Sileby goes to the grid, around £634 a year at 12p. A battery keeps more of it for the evening; the export rates table shows what suppliers pay.
Do solar panels work in winter in Sileby?
Yes, at a lower level. PVGIS gives Sileby 35.7 kWh per kWp in December and 36.3 in January, so a 12-panel system makes about 230 kWh and 230 kWh in those months, against 760 kWh in July. Winter output mostly covers daytime use rather than exporting.

PVGIS v5.2 for each town centroid, identical assumptions throughout. A few kWh either way is weather-year noise; a spread beyond about 30 kWh per kWp is real geography.
