How Halstead compares
Small towns rarely get published solar figures, so here are the numbers for Halstead. It is one of 46 Essex towns we track, and it ranks joint 22nd of 46 for solar yield, a town of 14,875 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,062 kWh per kWp a year, 2.91 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £945 of year one benefit, £247 of it from your own generation and £698 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 Halstead's own yield.
Braintree is the planning authority covering Halstead, which the House of Commons Library classes 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.

Who runs the grid in Halstead
Halstead is served by UK Power Networks: the town's centre falls inside its East England licence area on NESO's boundary map.
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.
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.

Beyond the panels: heating and car charging in Halstead
A heat pump in Halstead
A heat pump does most of its work from November to February. Over those four months, 12 panels in Halstead make about 1,160 kWh, against 3,160 kWh from May to August, so winter heating runs mostly on grid electricity and the tariff matters more than the roof.
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 Halstead
From April to September, 68% of a Halstead roof's yearly output arrives, peaking at about 810 kWh in June 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.
The calculator above includes a 7.4kW smart charger from £1,100 installed. Renters and flat owners with off-street parking can claim 75% of a chargepoint's cost, up to £500 per socket, until 31 March 2027 (gov.uk, checked 28 September 2026).

Common questions about solar in Halstead
What does a solar panel system produce in Halstead?
Each kWp of panels in Halstead makes 1,062 kWh a year on PVGIS figures, so a typical 12-panel system produces around 6,750 kWh, from about 240 kWh in December up to 810 kWh in June.
How much are solar panels in Halstead?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in Halstead before a battery. What Halstead changes is the return, about 6,750 kWh a year from that system, and your design call prices your actual roof.
Would a system in Halstead need approval from the network operator?
Halstead is on UK Power Networks' network (East England licence area). Systems up to 3.68kW per phase of inverter output follow G98: UK Power Networks is notified within 28 days of commissioning, with no approval needed first. Anything larger needs a G99 application before installation. 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. Our G98 vs G99 guide explains both routes.
How much can I earn from exporting solar in Halstead?
With typical use and no battery, a 12-panel system in Halstead exports about 5,818 kWh a year. At 12p per kWh that is roughly £698; 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 Halstead in winter?
It works, but the year is lopsided. 68% of a Halstead roof's output lands between April and September; the four months from November to February give about 1,160 kWh on a 12-panel system. Payback is worked out on the whole year, not the winter.
How Halstead compares with its neighbours
How the towns nearest Halstead compare on the same PVGIS settings, closest first.
| Town | kWh per kWp a year | vs Halstead |
|---|---|---|
| Halstead | 1,062 | this town |
| Braintree | 1,065 | +3 kWh |
| Great Notley | 1,062 | level |
| Sudbury | 1,054 | −8 kWh |
| Witham | 1,075 | +13 kWh |
| Tiptree | 1,077 | +15 kWh |
| Colchester | 1,082 | +20 kWh |
Each row is a PVGIS v5.2 run at that town's centre with the same settings. Treat gaps of a few kWh as noise and gaps over about 30 kWh per kWp as real differences in sunshine.
