Our GB average is 925 kWh per kWp a year, the mean of the 85 county PVGIS estimates we publish; at 899, Northumberland is 3% below it.
How Northumberland compares
Northumberland ranks joint 52nd of the 85 counties we track for solar yield. Self use does the heavy lifting here: of the £820 year one benefit on a typical 12 panel system, £247 comes from replacing 26.32p imports with your own generation, which is why battery sizing matters more than panel count.
These are county-level starting numbers. A town page gives the figure for its own centroid, and your design call replaces both with your roof, its shading and your bills.
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.

Import valued at 26.32p/kWh (Ofgem price cap average, Oct to Dec 2026); off-peak charging at 8.5p/kWh where used (a supplier's published off-peak rate, checked September 2026); export at the scenario you pick, from the dated tariff table. Prices are installed pricing, August 2026, standard installations; 530W LONGi panels at £1,000 per kWp. Estimates for illustration, not a quote: your free design call prices your actual roof.
Northern Powergrid and your Northumberland connection
On NESO's licence-area map, the middle of Northumberland falls in North East England, which Northern Powergrid operates.
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: Northern Powergrid 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: Northern Powergrid publishes a guaranteed standard of 45 working days to quote for a low voltage generation connection.
Parts of Northumberland are on a different network: some of its towns are served by SP Energy Networks. Each town page names its own operator, worked out from that town's own location.

Adding a heat pump or an EV charger in Northumberland
A heat pump in Northumberland
Heating demand peaks when solar is weakest. In Northumberland, a 12-panel system makes about 140 kWh in December and 170 kWh in January, a fraction of its 770 kWh in May, which is why a heat pump here is costed on its tariff first.
Grant support in England comes from the Boiler Upgrade Scheme: £7,500 for an air source or ground source heat pump, £2,500 for air-to-air, and an extra £1,500 until March 2027 where the home is heated by oil or LPG off the gas grid (gov.uk, checked 28 September 2026).
Charging an EV in Northumberland
Summer is where a car earns its place. In May, 12 panels in Northumberland make about 770 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 Northumberland
How much electricity do solar panels make in Northumberland?
About 5,720 kWh a year from 12 panels (6.36 kWp), on PVGIS satellite data for Northumberland: 899 kWh per kWp, or 2.46 peak sun hours a day on average. May is the strongest month, at about 770 kWh.
What does a typical solar system cost in Northumberland?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Northumberland, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 5,720 kWh a year. The final figure comes from your roof on the design call.
Which DNO covers Northumberland, and what does it need from me?
Northern Powergrid covers the centre of Northumberland. A home system of up to 3.68kW per phase is notified to Northern Powergrid within 28 days of commissioning under G98, and nothing waits on approval. Larger outputs need a G99 application before work starts. Northern Powergrid publishes a guaranteed standard of 45 working days to quote for a low voltage generation connection.
What happens to the solar I do not use in Northumberland?
Around £574 a year at 12p per kWh, for the roughly 4,781 kWh a 12-panel system in Northumberland exports with typical use. Rates vary by supplier and some need their own tariff; the export rates table is dated and sourced.
How much solar does Northumberland get in December?
December is the low point: about 140 kWh from a 12-panel system in Northumberland, on PVGIS data, rising to 770 kWh in May. From November to February the same system makes about 830 kWh in total, which is why a battery charged off-peak does more of the work in winter.
