Against Great Britain as a whole: Prestonpans makes 924 kWh per kWp a year, and the mean of our 85 county PVGIS estimates (our GB average) is 925, so Prestonpans is level with it.
How Prestonpans compares
Small towns rarely get published solar figures, so here are the numbers for Prestonpans. It is one of 5 East Lothian towns we track, and it ranks 4th of 5 for solar yield, a town of 10,623 people in the House of Commons Library settlement data. PVGIS gives its roofs 924 kWh per kWp a year, 2.53 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £840 of year one benefit, £247 of it from your own generation and £593 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Prestonpans' 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 Prestonpans sits with East Lothian, 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.

SP Energy Networks and your Prestonpans connection
On NESO's licence-area map, Prestonpans is in South and Central Scotland, which SP Energy Networks operates. That makes SP Energy 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 SP Energy Networks within 28 days of commissioning, with no prior approval.
Larger systems go through G99 instead, applied for before installation. On timing: 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 SP Energy Networks as it does every network operator.

Heat pumps and EV charging in Prestonpans
A heat pump in Prestonpans
Heating demand peaks when solar is weakest. In Prestonpans, a 12-panel system makes about 150 kWh in December and 190 kWh in January, a fraction of its 800 kWh in May, which is why a heat pump here is costed on its tariff first.
In Scotland, Home Energy Scotland offers a grant of up to £7,500 towards a heat pump, an optional interest-free loan of up to £7,500 on top, and £1,500 more for rural and island homes (Home Energy Scotland, checked 28 September 2026).
Charging an EV in Prestonpans
Summer is where a car earns its place. In May, 12 panels in Prestonpans make about 800 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 in Prestonpans: your questions answered
How much electricity do solar panels make in Prestonpans?
About 5,880 kWh a year from 12 panels (6.36 kWp), on PVGIS satellite data for Prestonpans: 924 kWh per kWp, or 2.53 peak sun hours a day on average. May is the strongest month, at about 800 kWh.
What does a typical solar system cost in Prestonpans?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Prestonpans, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 5,880 kWh a year. The final figure comes from your roof on the design call.
Which DNO covers Prestonpans, and what does it need from me?
SP Energy Networks covers Prestonpans. A home system of up to 3.68kW per phase is notified to SP Energy 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 SP Energy Networks as it does every network operator.
What happens to the solar I do not use in Prestonpans?
Around £593 a year at 12p per kWh, for the roughly 4,940 kWh a 12-panel system in Prestonpans exports with typical use. Rates vary by supplier and some need their own tariff; the export rates table is dated and sourced.
How much solar does Prestonpans get in December?
December is the low point: about 150 kWh from a 12-panel system in Prestonpans, on PVGIS data, rising to 800 kWh in May. From November to February the same system makes about 890 kWh in total, which is why a battery charged off-peak does more of the work in winter.
How Prestonpans compares with its neighbours
The six closest towns we publish, run through the identical PVGIS query as Prestonpans.
| Town | kWh per kWp a year | vs Prestonpans |
|---|---|---|
| Prestonpans | 924 | this town |
| Tranent | 901 | −23 kWh |
| Musselburgh | 900 | −24 kWh |
| Dalkeith | 897 | −27 kWh |
| Bonnyrigg | 896 | −28 kWh |
| Haddington | 925 | +1 kWh |
| Edinburgh | 915 | −9 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.
