Against Great Britain as a whole: Grimsby makes 1,028 kWh per kWp a year, and the mean of our 85 county PVGIS estimates (our GB average) is 925, so Grimsby is 11% above it.
How Grimsby compares
Grimsby is one of 22 Lincolnshire towns we track, and it ranks joint 8th of 22 for solar yield. The House of Commons Library settlement data classes it as a large town of 87,485 people. At 1,028 kWh per kWp a year, a typical 12 panel system here pays for itself in around 6.9 years on the 12p scenario: £919 of year one benefit against £6,360 installed, £247 of that benefit from cutting 26.32p imports with your own generation.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Grimsby'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.
Planning applications here go through North East Lincolnshire; nationally, the House of Commons Library classes Grimsby as a large 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 Grimsby
Northern Powergrid owns and runs the local electricity network in Grimsby, as part of its Yorkshire licence area.
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.
Above that, G99 means applying before the work is booked. Northern Powergrid publishes a guaranteed standard of 45 working days to quote for a low voltage generation connection.

Heat pumps and EV charging in Grimsby
A heat pump in Grimsby
Heating demand peaks when solar is weakest. In Grimsby, a 12-panel system makes about 220 kWh in December and 240 kWh in January, a fraction of its 810 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 Grimsby
Grimsby's May output, about 810 kWh from 12 panels, is several times the 70 kWh or so a typical home uses in daylight that month on our calculator's settings. Daytime charging turns that surplus into miles.
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).

Grimsby solar questions
How much electricity do solar panels make in Grimsby?
About 6,540 kWh a year from 12 panels (6.36 kWp), on PVGIS satellite data for Grimsby: 1,028 kWh per kWp, or 2.82 peak sun hours a day on average. May is the strongest month, at about 810 kWh.
Is solar more expensive in Grimsby?
Prices on this site are the same everywhere: £1,000 per kWp installed, which puts a 12-panel system at £6,360 in Grimsby, and a Duracell Dura16 installed with solar at £4,450 on top. The local part is generation, about 6,540 kWh a year here, which is what drives payback.
Which DNO covers Grimsby, and what does it need from me?
Northern Powergrid covers Grimsby. 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 could I earn from exporting in Grimsby?
On the 12p export scenario, a 12-panel system in Grimsby sends about 5,601 kWh a year to the grid, worth around £672. The export rates table compares what each supplier pays.
How much solar does Grimsby get in December?
December is the low point: about 220 kWh from a 12-panel system in Grimsby, on PVGIS data, rising to 810 kWh in May. From November to February the same system makes about 1,090 kWh in total, which is why a battery charged off-peak does more of the work in winter.
