How much a March roof makes, month by month
PVGIS puts March at 1,032 kWh per kWp a year, level with our Cambridgeshire county estimate. 67% of it arrives between April and September, peaking in May.

Against Great Britain as a whole: March makes 1,032 kWh per kWp a year, and the mean of our 85 county PVGIS estimates (our GB average) is 925, so March is 12% above it.
How March compares
Small towns rarely get published solar figures, so here are the numbers for March. It is one of 11 Cambridgeshire towns we track, and it ranks 9th of 11 for solar yield, a town of 21,175 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,032 kWh per kWp a year, 2.83 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £922 of year one benefit, £247 of it from your own generation and £675 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on March'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.
Any planning application in March sits with Fenland, and its official House of Commons Library settlement class is 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.

UK Power Networks and your March connection
On NESO's licence-area map, March is in East England, which UK Power Networks operates. That makes UK Power Networks 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 UK Power Networks within 28 days of commissioning, with no prior approval.
Above that, G99 means applying before the work is booked. Ofgem's guaranteed standard for a low voltage generation connection quotation is 45 working days, with £80 paid for each working day late, and it binds UK Power Networks as it does every network operator.

Heat pumps and EV charging in March
A heat pump in March
In December, the darkest month here, 12 panels in March make about 240 kWh. That is when a heat pump runs hardest, so its running cost in March 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 March
March's May output, about 790 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).

Solar in March: your questions answered
How much energy would 12 solar panels make in March?
March averages 2.83 peak sun hours a day, which PVGIS turns into 1,032 kWh per kWp a year. On a 12-panel, 6.36 kWp roof that is about 6,560 kWh, 67% of it between April and September.
Is solar more expensive in March?
Prices on this site are the same everywhere: £1,000 per kWp installed, which puts a 12-panel system at £6,360 in March, and a Duracell Dura16 installed with solar at £4,450 on top. The local part is generation, about 6,560 kWh a year here, which is what drives payback.
Who is the network operator in March, and do I need a G99 application?
The operator is UK Power Networks. 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. Ofgem's guaranteed standard for a low voltage generation connection quotation is 45 working days, with £80 paid for each working day late, and it binds UK Power Networks as it does every network operator. Your design call checks which route yours needs.
What could I earn from exporting in March?
On the 12p export scenario, a 12-panel system in March sends about 5,627 kWh a year to the grid, worth around £675. The export rates table compares what each supplier pays.
How does solar perform in March in the winter months?
December is the weakest month in March: about 240 kWh from 12 panels, against 790 kWh in May. The panels still generate on bright winter days; they just cover a smaller share of what the house uses.
How March 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 March |
|---|---|---|
| March | 1,032 | this town |
| Chatteris | 1,033 | +1 kWh |
| Wisbech | 1,038 | +6 kWh |
| Whittlesey | 1,035 | +3 kWh |
| Littleport | 1,029 | −3 kWh |
| Ely | 1,029 | −3 kWh |
| Downham Market | 1,026 | −6 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.
