How St Albans compares
St Albans is one of 27 Hertfordshire towns we track, and it ranks 8th of 27 for solar yield. The House of Commons Library settlement data classes it as a large town of 77,027 people. At 1,023 kWh per kWp a year, a typical 12 panel system here pays for itself in around 7.0 years on the 12p scenario: £915 of year one benefit against £6,360 installed, £247 of that benefit from cutting 26.32p imports with your own generation.
Every figure here assumes a clear, south-facing roof at 35 degrees. Yours will differ, which is what the free design call is for; until then, the calculator below tests panels, batteries and export rates on St Albans' own yield.
St Albans is its own local planning authority area, and its House of Commons Library settlement class is large 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 St Albans
On NESO's licence-area map, St Albans 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.

Beyond the panels: heating and car charging in St Albans
A heat pump in St Albans
Heating demand peaks when solar is weakest. In St Albans, a 12-panel system makes about 230 kWh in December and 250 kWh in January, a fraction of its 790 kWh in July, which is why a heat pump here is costed on its tariff first.
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 St Albans
St Albans' July 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.
If you rent, or own a flat, and have private off-street parking, the government chargepoint grant covers 75% of the cost, capped at £500 a socket, until 31 March 2027 (gov.uk, checked 28 September 2026). The calculator above prices a 7.4kW smart charger from £1,100 installed.

Common questions about solar in St Albans
How much electricity do solar panels make in St Albans?
About 6,510 kWh a year from 12 panels (6.36 kWp), on PVGIS satellite data for St Albans: 1,023 kWh per kWp, or 2.80 peak sun hours a day on average. July is the strongest month, at about 790 kWh.
Is solar more expensive in St Albans?
Prices on this site are the same everywhere: £1,000 per kWp installed, which puts a 12-panel system at £6,360 in St Albans, and a Duracell Dura16 installed with solar at £4,450 on top. The local part is generation, about 6,510 kWh a year here, which is what drives payback.
Which DNO covers St Albans, and what does it need from me?
UK Power Networks covers St Albans. 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 St Albans?
On the 12p export scenario, a 12-panel system in St Albans sends about 5,570 kWh a year to the grid, worth around £668. The export rates table compares what each supplier pays.
How much solar does St Albans get in December?
December is the low point: about 230 kWh from a 12-panel system in St Albans, on PVGIS data, rising to 790 kWh in July. From November to February the same system makes about 1,110 kWh in total, which is why a battery charged off-peak does more of the work in winter.
How St Albans compares with its neighbours
The six closest towns we publish, run through the identical PVGIS query as St Albans.
| Town | kWh per kWp a year | vs St Albans |
|---|---|---|
| St Albans | 1,023 | this town |
| London Colney | 1,022 | −1 kWh |
| Hatfield | 1,022 | −1 kWh |
| Harpenden | 1,017 | −6 kWh |
| Radlett | 1,018 | −5 kWh |
| Abbots Langley and Kings Langley | 1,016 | −7 kWh |
| Hemel Hempstead | 1,016 | −7 kWh |
PVGIS v5.2 for each town centroid, identical assumptions throughout. A few kWh either way is weather-year noise; a spread beyond about 30 kWh per kWp is real geography.
