How Haywards Heath compares
Among the places we publish figures for, Haywards Heath is one of 33 Sussex towns we track, and it ranks joint 27th of 33 for solar yield. It is a medium town in the House of Commons Library classification, with 42,728 residents, and its roofs see 2.98 peak sun hours a day across the year. That drives the standard 12 panel model to 6,920 kWh of generation, of which around 5,983 kWh is exported at 12p for £718 a year, with £247 saved on electricity you would otherwise buy at 26.32p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Haywards Heath's own yield, and 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.
Haywards Heath sits within Mid Sussex, its local planning authority, and the House of Commons Library classes it as a medium 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 Haywards Heath network
The distribution network operator (DNO) for Haywards Heath is UK Power Networks, which runs the South East 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 UK Power Networks is notified within 28 days of switch-on rather than asked beforehand.
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.

Heat pumps and EV charging in Haywards Heath
A heat pump in Haywards Heath
Solar and a heat pump pull in opposite directions through the year: Haywards Heath's roofs make 1,170 kWh from November to February on a 12-panel system, and 3,280 kWh from May to August. The heating season leans on the grid, so off-peak rates do the heavy lifting.
The Boiler Upgrade Scheme, open in England and Wales, takes £7,500 off an air source or ground source heat pump, or £2,500 off an air-to-air unit. Homes on oil or LPG with no mains gas get £1,500 more until March 2027 (gov.uk, checked 28 September 2026).
Charging an EV in Haywards Heath
From April to September, 68% of a Haywards Heath roof's yearly output arrives, peaking at about 860 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.

Solar in Haywards Heath: your questions answered
What could a roof in Haywards Heath generate?
PVGIS puts a roof in Haywards Heath at 1,088 kWh per kWp a year, 2.98 peak sun hours a day averaged across the seasons. A 12-panel, 6.36 kWp system makes about 6,920 kWh a year, most of it between April and September.
How much are solar panels in Haywards Heath?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in Haywards Heath before a battery. What Haywards Heath changes is the return, about 6,920 kWh a year from that system, and your design call prices your actual roof.
Do I need permission from the DNO for solar in Haywards Heath?
Usually not in advance. UK Power Networks, the network operator for Haywards Heath, 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 Haywards Heath?
With typical use and no battery, a 12-panel system in Haywards Heath exports about 5,983 kWh a year. At 12p per kWh that is roughly £718; 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 Haywards Heath?
Yes, at a lower level. PVGIS gives Haywards Heath 38.6 kWh per kWp in December and 40.9 in January, so a 12-panel system makes about 250 kWh and 260 kWh in those months, against 860 kWh in July. Winter output mostly covers daytime use rather than exporting.
