Against Great Britain as a whole: Alnwick makes 971 kWh per kWp a year, and the mean of our 85 county PVGIS estimates (our GB average) is 925, so Alnwick is 5% above it.
How Alnwick compares
Small towns rarely get published solar figures, so here are the numbers for Alnwick. It is one of 18 Northumberland towns we track, and it ranks 6th of 18 for solar yield, a town of 8,681 people in the House of Commons Library settlement data. PVGIS gives its roofs 971 kWh per kWp a year, 2.66 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £876 of year one benefit, £247 of it from your own generation and £629 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 Alnwick's own yield.
Planning applications here go through Northumberland; nationally, the House of Commons Library classes Alnwick 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.

The network operator for Alnwick
Alnwick is served by Northern Powergrid: the town's centre falls inside its North 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: 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.

Beyond the panels: heating and car charging in Alnwick
A heat pump in Alnwick
In December, the darkest month here, 12 panels in Alnwick make about 170 kWh. That is when a heat pump runs hardest, so its running cost in Alnwick comes down to the tariff and the flow temperature rather than the roof.
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 Alnwick
Summer is where a car earns its place. In May, 12 panels in Alnwick 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 Alnwick
How much electricity do solar panels make in Alnwick?
About 6,180 kWh a year from 12 panels (6.36 kWp), on PVGIS satellite data for Alnwick: 971 kWh per kWp, or 2.66 peak sun hours a day on average. May is the strongest month, at about 810 kWh.
What does a typical solar system cost in Alnwick?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Alnwick, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 6,180 kWh a year. The final figure comes from your roof on the design call.
Which DNO covers Alnwick, and what does it need from me?
Northern Powergrid covers Alnwick. 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 Alnwick?
Around £629 a year at 12p per kWh, for the roughly 5,239 kWh a 12-panel system in Alnwick 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 Alnwick get in December?
December is the low point: about 170 kWh from a 12-panel system in Alnwick, on PVGIS data, rising to 810 kWh in May. From November to February the same system makes about 950 kWh in total, which is why a battery charged off-peak does more of the work in winter.
How Alnwick compares with its neighbours
Same satellite dataset, same assumptions, so the differences are real geography rather than modelling noise.
| Town | kWh per kWp a year | vs Alnwick |
|---|---|---|
| Alnwick | 971 | this town |
| Morpeth | 957 | −14 kWh |
| Ashington | 976 | +5 kWh |
| Stakeford | 976 | +5 kWh |
| Bedlington | 968 | −3 kWh |
| Blyth | 980 | +9 kWh |
| Cramlington | 952 | −19 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.
