Against Great Britain as a whole: Louth makes 1,028 kWh per kWp a year, and the mean of our 85 county PVGIS estimates (our GB average) is 925, so Louth is 11% above it.
How Louth compares
Small towns rarely get published solar figures, so here are the numbers for Louth. It is one of 22 Lincolnshire towns we track, and it ranks joint 8th of 22 for solar yield, a town of 18,312 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,028 kWh per kWp a year, 2.82 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £919 of year one benefit, £247 of it from your own generation and £672 from export at 12p.
These are starting numbers, not a quote. The calculator below opens on Louth's own PVGIS figure; change the panels, the battery or the export rate and it reruns. The design call replaces every assumption with your roof and your bills.
Louth sits within East Lindsey, its local planning authority, and the House of Commons Library classes it 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.

Connecting solar to the Louth network
On NESO's licence-area map, Louth is in Yorkshire, which Northern Powergrid operates. That makes Northern Powergrid the network operator for any system fitted here.
Most home systems stay within 3.68kW per phase of inverter output, which puts them on G98, a notification to Northern Powergrid within 28 days of switch-on. Panel count does not decide it; the inverter and any battery do.
Anything bigger is a G99 case and is applied for first. Northern Powergrid publishes a guaranteed standard of 45 working days to quote for a low voltage generation connection.

Adding a heat pump or an EV charger in Louth
A heat pump in Louth
Solar and a heat pump pull in opposite directions through the year: Louth's roofs make 1,100 kWh from November to February on a 12-panel system, and 3,090 kWh from May to August. The heating season leans on the grid, so off-peak rates do the heavy lifting.
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 Louth
A 12-panel roof in Louth makes about 810 kWh in May. A typical home uses around 70 kWh of that in daylight (the calculator's typical-use settings), which leaves most of the month's output for an EV or for export.
Renters and flat owners with private off-street parking can get 75% off a chargepoint and its installation, up to £500 per socket, until 31 March 2027 (gov.uk, checked 28 September 2026). The calculator above adds a 7.4kW smart charger from £1,100 installed.

Common questions about solar in Louth
What could a roof in Louth generate?
PVGIS puts a roof in Louth at 1,028 kWh per kWp a year, 2.82 peak sun hours a day averaged across the seasons. A 12-panel, 6.36 kWp system makes about 6,540 kWh a year, most of it between April and September.
What would 12 solar panels cost in Louth?
£6,360 for 12 panels (6.36 kWp), the same as in every other place we cover, because solar is priced at £1,000 per kWp installed rather than by area. A battery adds its own installed price on top. Where Louth differs is output: about 6,540 kWh a year from that system.
Do I need permission from the DNO for solar in Louth?
Usually not in advance. Northern Powergrid, the network operator for Louth, only needs a G98 notification within 28 days of commissioning for systems up to 3.68kW per phase. Bigger inverter or battery outputs need G99 approval first. Northern Powergrid publishes a guaranteed standard of 45 working days to quote for a low voltage generation connection. "See our DNO explainer.
How much would export pay on a system in Louth?
It is exported. With typical use and no battery, about 5,601 kWh of the 6,540 kWh a 12-panel system makes in Louth goes to the grid, around £672 a year at 12p. A battery keeps more of it for the evening; the export rates table shows what suppliers pay.
Do solar panels work in winter in Louth?
Yes, at a lower level. PVGIS gives Louth 35.6 kWh per kWp in December and 38 in January, so a 12-panel system makes about 230 kWh and 240 kWh in those months, against 810 kWh in May. Winter output mostly covers daytime use rather than exporting.
How Louth 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 Louth |
|---|---|---|
| Louth | 1,028 | this town |
| Mablethorpe | 1,034 | +6 kWh |
| Humberston and New Waltham | 1,031 | +3 kWh |
| Horncastle | 1,014 | −14 kWh |
| Cleethorpes | 1,026 | −2 kWh |
| Grimsby | 1,028 | level |
| Immingham | 1,012 | −16 kWh |
Same PVGIS v5.2 query for every town. Small differences are within year-to-year weather; more than about 30 kWh per kWp apart is geography.
