How Great Notley compares
Small towns rarely get published solar figures, so here are the numbers for Great Notley. It is one of 46 Essex towns we track, and it ranks joint 22nd of 46 for solar yield, a town of 8,135 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 Great Notley's own yield.
Any planning application in Great Notley sits with Braintree, and its official House of Commons Library settlement class is 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.

Generation is modelled from PVGIS satellite data for Great Notley's own coordinates (51.8609, 0.5273), using the same 26.32p/kWh import value and £1,000 per kWp installed pricing as every Clearline estimate; the methodology is on our help page.
The network operator for Great Notley
On NESO's licence-area map, Great Notley is in East England, which UK Power Networks operates. That makes UK Power Networks the network operator for any system fitted here.
Below 3.68kW per phase of inverter and battery output, the G98 route applies: the installation is notified to UK Power Networks within 28 days of commissioning, with no prior approval.
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 Great Notley
A heat pump in Great Notley
Heating demand peaks when solar is weakest. In Great Notley, a 12-panel system makes about 240 kWh in December and 250 kWh in January, a fraction of its 810 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 Great Notley
Summer is where a car earns its place. In July, 12 panels in Great Notley make about 810 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.
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.

Common questions about solar in Great Notley
How much energy would 12 solar panels make in Great Notley?
Great Notley averages 2.91 peak sun hours a day, which PVGIS turns into 1,062 kWh per kWp a year. On a 12-panel, 6.36 kWp roof that is about 6,750 kWh, 68% of it between April and September.
What does a typical solar system cost in Great Notley?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Great Notley, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 6,750 kWh a year. The final figure comes from your roof on the design call.
Who is the network operator in Great Notley, 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 Great Notley?
Around £698 a year at 12p per kWh, for the roughly 5,818 kWh a 12-panel system in Great Notley 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 Great Notley in the winter months?
December is the weakest month in Great Notley: about 240 kWh from 12 panels, against 810 kWh in July. The panels still generate on bright winter days; they just cover a smaller share of what the house uses.
