Against Great Britain as a whole: Holbeach makes 1,046 kWh per kWp a year, and the mean of our 85 county PVGIS estimates (our GB average) is 925, so Holbeach is 13% above it.
How Holbeach compares
Small towns rarely get published solar figures, so here are the numbers for Holbeach. It is one of 22 Lincolnshire towns we track, and it ranks 1st of 22 for solar yield, a town of 8,830 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,046 kWh per kWp a year, 2.87 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £933 of year one benefit, £247 of it from your own generation and £686 from export at 12p.
These are starting numbers, not a quote. The calculator below opens on Holbeach'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.
Holbeach sits within South Holland, 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.

Generation is modelled from PVGIS satellite data for Holbeach's own coordinates (52.80423, 0.01511), 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.
Connecting solar to the Holbeach network
On NESO's licence-area map, Holbeach is in East Midlands, which National Grid Electricity Distribution (NGED) operates. That makes NGED 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 NGED within 28 days of commissioning, with no prior approval.
A bigger inverter or battery output needs a G99 application in advance. NGED's guaranteed standards give 45 working days for a low voltage generation quotation, with £80 paid for each working day late.

Adding a heat pump or an EV charger in Holbeach
A heat pump in Holbeach
Solar and a heat pump pull in opposite directions through the year: Holbeach's roofs make 1,140 kWh from November to February on a 12-panel system, and 3,120 kWh from May to August. The heating season leans on the grid, so off-peak rates do the heavy lifting.
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 Holbeach
From April to September, 67% of a Holbeach roof's yearly output arrives, peaking at about 810 kWh in May on 12 panels. A car parked at home in daylight can soak up what the house, at around 70 kWh of daytime use that month, cannot.
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).

Holbeach solar questions
What could a roof in Holbeach generate?
PVGIS puts a roof in Holbeach at 1,046 kWh per kWp a year, 2.87 peak sun hours a day averaged across the seasons. A 12-panel, 6.36 kWp system makes about 6,650 kWh a year, most of it between April and September.
How much are solar panels in Holbeach?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in Holbeach before a battery. What Holbeach changes is the return, about 6,650 kWh a year from that system, and your design call prices your actual roof.
Do I need permission from the DNO for solar in Holbeach?
Usually not in advance. NGED, the network operator for Holbeach, 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. NGED's guaranteed standards give 45 working days for a low voltage generation quotation, with £80 paid for each working day late. "See our DNO explainer.
How much can I earn from exporting solar in Holbeach?
With typical use and no battery, a 12-panel system in Holbeach exports about 5,716 kWh a year. At 12p per kWh that is roughly £686; a supplier paying more, or a battery that keeps more for the evening, changes the figure. See the export rates table.
Do solar panels work in winter in Holbeach?
Yes, at a lower level. PVGIS gives Holbeach 36.9 kWh per kWp in December and 38.9 in January, so a 12-panel system makes about 230 kWh and 250 kWh in those months, against 810 kWh in May. Winter output mostly covers daytime use rather than exporting.
How Holbeach compares with its neighbours
How the towns nearest Holbeach compare on the same PVGIS settings, closest first.
| Town | kWh per kWp a year | vs Holbeach |
|---|---|---|
| Holbeach | 1,046 | this town |
| Spalding | 1,036 | −10 kWh |
| Wisbech | 1,038 | −8 kWh |
| Boston | 1,043 | −3 kWh |
| Deeping St James | 1,030 | −16 kWh |
| Bourne | 1,028 | −18 kWh |
| King's Lynn | 1,027 | −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.
