Sunlight in Boston, in numbers
From 36.1 kWh per kWp in December to 126.8 in May: a roof in Boston makes 3.5 times as much in its best month as in its darkest, and 1,043 kWh per kWp across the year.

How Boston compares
Among the places we publish figures for, Boston is one of 22 Lincolnshire towns we track, and it ranks 2nd of 22 for solar yield. It is a medium town in the House of Commons Library classification, with 45,275 residents, and its roofs see 2.86 peak sun hours a day across the year. That drives the standard 12 panel model to 6,633 kWh of generation, of which around 5,697 kWh is exported at 12p for £684 a year, with £247 saved on electricity you would otherwise buy at 26.32p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Boston'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.
Boston is its own local planning authority area, and its House of Commons Library settlement class is medium 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 Boston
National Grid Electricity Distribution (NGED) owns and runs the local electricity network in Boston, as part of its East Midlands 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: NGED 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: NGED's guaranteed standards give 45 working days for a low voltage generation quotation, with £80 paid for each working day late.

Heat pumps and EV charging in Boston
A heat pump in Boston
In December, the darkest month here, 12 panels in Boston make about 230 kWh. That is when a heat pump runs hardest, so its running cost in Boston comes down to the tariff and the flow temperature rather than the roof.
The Boiler Upgrade Scheme, open in England and Wales, takes £7,500 off an air source or ground source heat pump, or £2,500 off an air-to-air unit. Homes on oil or LPG with no mains gas get £1,500 more until March 2027 (gov.uk, checked 28 September 2026).
Charging an EV in Boston
Summer is where a car earns its place. In May, 12 panels in Boston 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.
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.

Solar panel servicing and repair in Boston
If a system in Boston is underperforming, start with the guides below: repair benchmarks, service scope, and the inverter question.
Solar in Boston: your questions answered
How much energy would 12 solar panels make in Boston?
Boston averages 2.86 peak sun hours a day, which PVGIS turns into 1,043 kWh per kWp a year. On a 12-panel, 6.36 kWp roof that is about 6,630 kWh, 68% of it between April and September.
What does a typical solar system cost in Boston?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Boston, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 6,630 kWh a year. The final figure comes from your roof on the design call.
Who is the network operator in Boston, and do I need a G99 application?
The operator is National Grid Electricity Distribution (NGED). Most home systems use the G98 route, a notification within 28 days of switch-on for up to 3.68kW per phase, so nothing waits on the network. Above that, G99 applies and has to be granted first. NGED's guaranteed standards give 45 working days for a low voltage generation quotation, with £80 paid for each working day late. Your design call checks which route yours needs.
What happens to the solar I do not use in Boston?
Around £684 a year at 12p per kWh, for the roughly 5,697 kWh a 12-panel system in Boston exports with typical use. Rates vary by supplier and some need their own tariff; the export rates table is dated and sourced.
How does solar perform in Boston in the winter months?
December is the weakest month in Boston: about 230 kWh from 12 panels, against 810 kWh in May. The panels still generate on bright winter days; they just cover a smaller share of what the house uses.
How Boston 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 Boston |
|---|---|---|
| Boston | 1,043 | this town |
| Holbeach | 1,046 | +3 kWh |
| Spalding | 1,036 | −7 kWh |
| Sleaford | 1,031 | −12 kWh |
| Horncastle | 1,014 | −29 kWh |
| Skegness | 1,014 | −29 kWh |
| Bourne | 1,028 | −15 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.
