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.
Treat these as calibration rather than a quote. The calculator below runs the same model, defaulted to Hailsham's own yield, and at Hailsham's 1,158 kWh per kWp it prices a 12 panel system at £6,360 installed before any battery. Your free design call reworks every number for your actual roof, its shading and your usage.
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.

A 12 panel, 6.36 kWp system in Hailsham generates around 7,365 kWh a year, worth around £1,018 in year one on the 12p export scenario.
Generation is modelled from PVGIS satellite data for Hailsham's own coordinates (50.86631, 0.25596), using the same 26.32p/kWh import value and £1,000 per kWp installed pricing as every Clearline estimate, with the full methodology, sourcing and assumptions set out on our help page.

Usable capacity, kW output, round trip losses and chemistry, in plain terms.
Read the guide →What it really costs to charge an EV at home versus in public
Home off-peak charging costs a fraction of the public price. The arithmetic, and the tariff it depends on.
Read the guide →Are heat pumps worth it? The real 2026 numbers
Electricity costs 3.3x gas per kWh. A heat pump is about 3x as efficient. The numbers nearly cancel out.

A battery buys cheap and uses dear. The tariff decides how much that is worth.
