How Haslemere compares
Small towns rarely get published solar figures, so here are the numbers for Haslemere. It is one of 47 Surrey towns we track, and it ranks 3rd of 47 for solar yield, a town of 12,350 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,042 kWh per kWp a year, 2.85 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £930 of year one benefit, £247 of it from your own generation and £683 from export at 12p.
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 Haslemere's own yield.
Haslemere sits within Waverley, 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 Haslemere network
The distribution network operator (DNO) for Haslemere is Scottish and Southern Electricity Networks (SSEN), which runs the Southern England licence area.
For a typical home the paperwork is light: a system of up to 3.68kW per phase goes through G98, which means SSEN is notified within 28 days of switch-on rather than asked beforehand.
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 Haslemere
A heat pump in Haslemere
Solar and a heat pump pull in opposite directions through the year: Haslemere's roofs make 1,080 kWh from November to February on a 12-panel system, and 3,160 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 Haslemere
From April to September, 69% of a Haslemere roof's yearly output arrives, peaking at about 830 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.
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 Haslemere: your questions answered
What could a roof in Haslemere generate?
PVGIS puts a roof in Haslemere at 1,042 kWh per kWp a year, 2.85 peak sun hours a day averaged across the seasons. A 12-panel, 6.36 kWp system makes about 6,630 kWh a year, most of it between April and September.
How much are solar panels in Haslemere?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in Haslemere before a battery. What Haslemere changes is the return, about 6,630 kWh a year from that system, and your design call prices your actual roof.
Do I need permission from the DNO for solar in Haslemere?
Usually not in advance. SSEN, the network operator for Haslemere, 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. 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. "See our DNO explainer.
How much can I earn from exporting solar in Haslemere?
With typical use and no battery, a 12-panel system in Haslemere exports about 5,690 kWh a year. At 12p per kWh that is roughly £683; 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 Haslemere?
Yes, at a lower level. PVGIS gives Haslemere 32.6 kWh per kWp in December and 37.9 in January, so a 12-panel system makes about 210 kWh and 240 kWh in those months, against 830 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.
