How Maldon compares
Small towns rarely get published solar figures, so here are the numbers for Maldon. It is one of 46 Essex towns we track, and it ranks 9th of 46 for solar yield, a town of 24,473 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,086 kWh per kWp a year, 2.97 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £963 of year one benefit, £247 of it from your own generation and £716 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Maldon'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.
Maldon is its own local planning authority area, and its 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.

The network operator for Maldon
On NESO's licence-area map, Maldon 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 Maldon
A heat pump in Maldon
In December, the darkest month here, 12 panels in Maldon make about 250 kWh. That is when a heat pump runs hardest, so its running cost in Maldon 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 Maldon
Maldon's July output, about 840 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 Maldon: your questions answered
How much electricity do solar panels make in Maldon?
About 6,910 kWh a year from 12 panels (6.36 kWp), on PVGIS satellite data for Maldon: 1,086 kWh per kWp, or 2.97 peak sun hours a day on average. July is the strongest month, at about 840 kWh.
Is solar more expensive in Maldon?
Prices on this site are the same everywhere: £1,000 per kWp installed, which puts a 12-panel system at £6,360 in Maldon, and a Duracell Dura16 installed with solar at £4,450 on top. The local part is generation, about 6,910 kWh a year here, which is what drives payback.
Which DNO covers Maldon, and what does it need from me?
UK Power Networks covers Maldon. A home system of up to 3.68kW per phase is notified to UK Power Networks within 28 days of commissioning under G98, and nothing waits on approval. Larger outputs need a G99 application before work starts. 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.
What could I earn from exporting in Maldon?
On the 12p export scenario, a 12-panel system in Maldon sends about 5,970 kWh a year to the grid, worth around £716. The export rates table compares what each supplier pays.
How much solar does Maldon get in December?
December is the low point: about 250 kWh from a 12-panel system in Maldon, on PVGIS data, rising to 840 kWh in July. From November to February the same system makes about 1,190 kWh in total, which is why a battery charged off-peak does more of the work in winter.
How Maldon 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 Maldon |
|---|---|---|
| Maldon | 1,086 | this town |
| Witham | 1,075 | −11 kWh |
| Tiptree | 1,077 | −9 kWh |
| South Woodham Ferrers | 1,088 | +2 kWh |
| Chelmsford | 1,061 | −25 kWh |
| Burnham-on-Crouch | 1,122 | +36 kWh |
| Hockley and Hawkwell | 1,102 | +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.
