How East Lothian compares
East Lothian ranks 57th of the 85 counties we track for solar yield. Self use does the heavy lifting here: of the £800 year one benefit on a typical 12 panel system, £247 comes from replacing 26.32p imports with your own generation, which is why battery sizing matters more than panel count.
These are county-level starting numbers. A town page gives the figure for its own centroid, and your design call replaces both with your roof, its shading and your bills.
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 East Lothian
On NESO's licence-area map, the middle of East Lothian falls in South and Central Scotland, which SP Energy Networks operates, and so do all the towns we cover in the county.
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: SP Energy Networks is notified within 28 days of commissioning and nothing has to be approved first.
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 SP Energy Networks as it does every network operator.

Adding a heat pump or an EV charger in East Lothian
A heat pump in East Lothian
Heating demand peaks when solar is weakest. In East Lothian, a 12-panel system makes about 130 kWh in December and 160 kWh in January, a fraction of its 760 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 East Lothian
East Lothian's May output, about 760 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).

Which DNO covers East Lothian, and what does it need from me?
SP Energy Networks covers East Lothian. 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 could I earn from exporting in East Lothian?
On the 12p export scenario, a 12-panel system in East Lothian sends about 4,609 kWh a year to the grid, worth around £553. The export rates table compares what each supplier pays.
How much solar does East Lothian get in December?
December is the low point: about 130 kWh from a 12-panel system in East Lothian, on PVGIS data, rising to 760 kWh in May. From November to February the same system makes about 790 kWh in total, which is why a battery charged off-peak does more of the work in winter.
