How Maidstone compares
Maidstone is one of 44 Kent towns we track, and it ranks 23rd of 44 for solar yield. The House of Commons Library settlement data classes it as a large town of 116,187 people. At 1,056 kWh per kWp a year, a typical 12 panel system here pays for itself in around 6.8 years on the 12p scenario: £940 of year one benefit against £6,360 installed, £247 of that benefit from cutting 26.32p imports with your own generation.
These are starting numbers, not a quote. The calculator below opens on Maidstone'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.
Planning applications in Maidstone go to its own council, and the House of Commons Library classes it as a large 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 Maidstone network
Maidstone sits in UK Power Networks' South East England licence area, so UK Power Networks is the network operator (DNO) any solar panels or battery here are registered with.
G98 is the simple route. If the inverter, plus any battery, stays at or under 3.68kW per phase, UK Power Networks only has to be told within 28 days after the system is commissioned.
A bigger inverter or battery output needs a G99 application in advance. 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 Maidstone
A heat pump in Maidstone
Solar and a heat pump pull in opposite directions through the year: Maidstone's roofs make 1,140 kWh from November to February on a 12-panel system, and 3,170 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 Maidstone
From April to September, 68% of a Maidstone roof's yearly output arrives, peaking at about 820 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 Maidstone
What could a roof in Maidstone generate?
PVGIS puts a roof in Maidstone at 1,056 kWh per kWp a year, 2.89 peak sun hours a day averaged across the seasons. A 12-panel, 6.36 kWp system makes about 6,720 kWh a year, most of it between April and September.
How much are solar panels in Maidstone?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in Maidstone before a battery. What Maidstone changes is the return, about 6,720 kWh a year from that system, and your design call prices your actual roof.
Do I need permission from the DNO for solar in Maidstone?
Usually not in advance. UK Power Networks, the network operator for Maidstone, 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. 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. "See our DNO explainer.
How much can I earn from exporting solar in Maidstone?
With typical use and no battery, a 12-panel system in Maidstone exports about 5,779 kWh a year. At 12p per kWh that is roughly £694; 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 Maidstone?
Yes, at a lower level. PVGIS gives Maidstone 38.3 kWh per kWp in December and 38.7 in January, so a 12-panel system makes about 240 kWh and 250 kWh in those months, against 820 kWh in July. Winter output mostly covers daytime use rather than exporting.
How Maidstone compares with its neighbours
Same satellite dataset, same assumptions, so the differences are real geography rather than modelling noise.
| Town | kWh per kWp a year | vs Maidstone |
|---|---|---|
| Maidstone | 1,056 | this town |
| Bearsted | 1,055 | −1 kWh |
| Larkfield | 1,059 | +3 kWh |
| Kings Hill | 1,059 | +3 kWh |
| Snodland | 1,051 | −5 kWh |
| Chatham | 1,043 | −13 kWh |
| Gillingham (Medway) | 1,047 | −9 kWh |
Each row is a PVGIS v5.2 run at that town's centre with the same settings. Treat gaps of a few kWh as noise and gaps over about 30 kWh per kWp as real differences in sunshine.
