How Maidenhead compares
Maidenhead is one of 20 Berkshire towns we track, and it ranks joint 7th of 20 for solar yield. The House of Commons Library settlement data classes it as a large town of 70,635 people. At 1,027 kWh per kWp a year, a typical 12 panel system here pays for itself in around 6.9 years on the 12p scenario: £918 of year one benefit against £6,360 installed, £247 of that benefit from cutting 26.32p imports with your own generation.
Every figure here assumes a clear, south-facing roof at 35 degrees. Yours will differ, which is what the free design call is for; until then, the calculator below tests panels, batteries and export rates on Maidenhead's own yield.
Windsor and Maidenhead is the planning authority covering Maidenhead, which the House of Commons Library classes 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.

Who runs the grid in Maidenhead
Maidenhead sits in Scottish and Southern Electricity Networks' Southern England licence area, so SSEN is the network operator (DNO) any solar panels or battery here are registered with.
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.
A bigger inverter or battery output needs a G99 application in advance. 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.

Beyond the panels: heating and car charging in Maidenhead
A heat pump in Maidenhead
A heat pump does most of its work from November to February. Over those four months, 12 panels in Maidenhead make about 1,120 kWh, against 3,080 kWh from May to August, so winter heating runs mostly on grid electricity and the tariff matters more than the roof.
Grant support in England comes from the Boiler Upgrade Scheme: £7,500 for an air source or ground source heat pump, £2,500 for air-to-air, and an extra £1,500 until March 2027 where the home is heated by oil or LPG off the gas grid (gov.uk, checked 28 September 2026).
Charging an EV in Maidenhead
A 12-panel roof in Maidenhead makes about 800 kWh in July. 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 Maidenhead: your questions answered
What does a solar panel system produce in Maidenhead?
Each kWp of panels in Maidenhead makes 1,027 kWh a year on PVGIS figures, so a typical 12-panel system produces around 6,530 kWh, from about 230 kWh in December up to 800 kWh in July.
How much are solar panels in Maidenhead?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in Maidenhead before a battery. What Maidenhead changes is the return, about 6,530 kWh a year from that system, and your design call prices your actual roof.
Would a system in Maidenhead need approval from the network operator?
Maidenhead is on Scottish and Southern Electricity Networks' network (Southern England licence area). Systems up to 3.68kW per phase of inverter output follow G98: SSEN is notified within 28 days of commissioning, with no approval needed first. Anything larger needs a G99 application before installation. 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. Our G98 vs G99 guide explains both routes.
How much can I earn from exporting solar in Maidenhead?
With typical use and no battery, a 12-panel system in Maidenhead exports about 5,595 kWh a year. At 12p per kWh that is roughly £671; a supplier paying more, or a battery that keeps more for the evening, changes the figure. See the export rates table.
Is solar worth it in Maidenhead in winter?
It works, but the year is lopsided. 68% of a Maidenhead roof's output lands between April and September; the four months from November to February give about 1,120 kWh on a 12-panel system. Payback is worked out on the whole year, not the winter.
