How Gravesend compares
Among the places we publish figures for, Gravesend is one of 44 Kent towns we track, and it ranks 26th of 44 for solar yield. It is a medium town in the House of Commons Library classification, with 59,048 residents, and its roofs see 2.89 peak sun hours a day across the year. That drives the standard 12 panel model to 6,697 kWh of generation, of which around 5,760 kWh is exported at 12p for £691 a year, with £247 saved on electricity you would otherwise buy at 26.32p.
These are starting numbers, not a quote. The calculator below opens on Gravesend'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.
Any planning application in Gravesend sits with Gravesham, 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.

The network operator for Gravesend
Gravesend is served by UK Power Networks: the town's centre falls inside its South East England 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 UK Power Networks within 28 days of switch-on. Panel count does not decide it; the inverter and any battery do.
Larger systems go through G99 instead, applied for before installation. On timing: Ofgem's guaranteed standard for a low voltage generation connection quotation is 45 working days, with £80 paid for each working day late, and it binds UK Power Networks as it does every network operator.

Adding a heat pump or an EV charger in Gravesend
A heat pump in Gravesend
In December, the darkest month here, 12 panels in Gravesend make about 240 kWh. That is when a heat pump runs hardest, so its running cost in Gravesend comes down to the tariff and the flow temperature rather than the roof.
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 Gravesend
Summer is where a car earns its place. In July, 12 panels in Gravesend make about 830 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.
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 Gravesend
How much energy would 12 solar panels make in Gravesend?
Gravesend averages 2.89 peak sun hours a day, which PVGIS turns into 1,053 kWh per kWp a year. On a 12-panel, 6.36 kWp roof that is about 6,700 kWh, 68% of it between April and September.
What does a typical solar system cost in Gravesend?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Gravesend, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 6,700 kWh a year. The final figure comes from your roof on the design call.
Who is the network operator in Gravesend, and do I need a G99 application?
The operator is UK Power Networks. Most home systems use the G98 route, a notification within 28 days of switch-on for up to 3.68kW per phase, so nothing waits on the network. Above that, G99 applies and has to be granted first. Ofgem's guaranteed standard for a low voltage generation connection quotation is 45 working days, with £80 paid for each working day late, and it binds UK Power Networks as it does every network operator. Your design call checks which route yours needs.
What happens to the solar I do not use in Gravesend?
Around £691 a year at 12p per kWh, for the roughly 5,760 kWh a 12-panel system in Gravesend exports with typical use. Rates vary by supplier and some need their own tariff; the export rates table is dated and sourced.
How does solar perform in Gravesend in the winter months?
December is the weakest month in Gravesend: about 240 kWh from 12 panels, against 830 kWh in July. The panels still generate on bright winter days; they just cover a smaller share of what the house uses.
How Gravesend compares with its neighbours

| Tilbury | 1,057 | +4 kWh |
| Chadwell St Mary | 1,057 | +4 kWh |
| Swanscombe | 1,041 | −12 kWh |
| Longfield, New Ash Green and Hartley | 1,049 | −4 kWh |
| Grays | 1,055 | +2 kWh |
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.
