How Hailsham compares
Small towns rarely get published solar figures, so here are the numbers for Hailsham. It is one of 33 Sussex towns we track, and it ranks joint 7th of 33 for solar yield, a town of 23,475 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,158 kWh per kWp a year, 3.17 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £1,018 of year one benefit, £247 of it from your own generation and £771 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 Hailsham's own yield.
Planning applications here go through Wealden; nationally, the House of Commons Library classes Hailsham 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.

The network operator for Hailsham
UK Power Networks owns and runs the local electricity network in Hailsham, as part of its South East England licence area.
What decides the paperwork is the inverter and battery output, not the number of panels. Up to 3.68kW per phase, a system follows G98: UK Power Networks is notified within 28 days of commissioning and nothing has to be approved first.
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.

Beyond the panels: heating and car charging in Hailsham
A heat pump in Hailsham
Heating demand peaks when solar is weakest. In Hailsham, a 12-panel system makes about 260 kWh in December and 270 kWh in January, a fraction of its 920 kWh in July, which is why a heat pump here is costed on its tariff first.
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 Hailsham
Summer is where a car earns its place. In July, 12 panels in Hailsham make about 920 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.

Solar panel servicing and repair in Hailsham
If a system in Hailsham is underperforming, start with the guides below: repair benchmarks, service scope, and the inverter question.
Solar in Hailsham: your questions answered
How much energy would 12 solar panels make in Hailsham?
Hailsham averages 3.17 peak sun hours a day, which PVGIS turns into 1,158 kWh per kWp a year. On a 12-panel, 6.36 kWp roof that is about 7,360 kWh, 69% of it between April and September.
What does a typical solar system cost in Hailsham?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Hailsham, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 7,360 kWh a year. The final figure comes from your roof on the design call.
Who is the network operator in Hailsham, 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 Hailsham?
Around £771 a year at 12p per kWh, for the roughly 6,428 kWh a 12-panel system in Hailsham 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 Hailsham in the winter months?
December is the weakest month in Hailsham: about 260 kWh from 12 panels, against 920 kWh in July. The panels still generate on bright winter days; they just cover a smaller share of what the house uses.
