How Yarm compares
Small towns rarely get published solar figures, so here are the numbers for Yarm. It is one of 122 Yorkshire towns we track, and it ranks 108th of 122 for solar yield, a town of 9,883 people in the House of Commons Library settlement data. PVGIS gives its roofs 921 kWh per kWp a year, 2.52 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £838 of year one benefit, £247 of it from your own generation and £591 from export at 12p.
These are starting numbers, not a quote. The calculator below opens on Yarm's own PVGIS figure; change the panels, the battery or the export rate and it reruns. The design call replaces every assumption with your roof and your bills.
Planning applications here go through Stockton-on-Tees; nationally, the House of Commons Library classes Yarm as a 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 Yarm
The distribution network operator (DNO) for Yarm is Northern Powergrid, which runs the North East England licence area.
G98 is the simple route. If the inverter, plus any battery, stays at or under 3.68kW per phase, Northern Powergrid only has to be told within 28 days after the system is commissioned.
Above that, G99 means applying before the work is booked. Northern Powergrid publishes a guaranteed standard of 45 working days to quote for a low voltage generation connection.

Adding a heat pump or an EV charger in Yarm
A heat pump in Yarm
In December, the darkest month here, 12 panels in Yarm make about 180 kWh. That is when a heat pump runs hardest, so its running cost in Yarm comes down to the tariff and the flow temperature rather than the roof.
The Boiler Upgrade Scheme, open in England and Wales, takes £7,500 off an air source or ground source heat pump, or £2,500 off an air-to-air unit. Homes on oil or LPG with no mains gas get £1,500 more until March 2027 (gov.uk, checked 28 September 2026).
Charging an EV in Yarm
Yarm's May output, about 750 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).

Yarm solar questions
How much energy would 12 solar panels make in Yarm?
Yarm averages 2.52 peak sun hours a day, which PVGIS turns into 921 kWh per kWp a year. On a 12-panel, 6.36 kWp roof that is about 5,860 kWh, 70% of it between April and September.
Is solar more expensive in Yarm?
Prices on this site are the same everywhere: £1,000 per kWp installed, which puts a 12-panel system at £6,360 in Yarm, and a Duracell Dura16 installed with solar at £4,450 on top. The local part is generation, about 5,860 kWh a year here, which is what drives payback.
Who is the network operator in Yarm, and do I need a G99 application?
The operator is Northern Powergrid. 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. Northern Powergrid publishes a guaranteed standard of 45 working days to quote for a low voltage generation connection. Your design call checks which route yours needs.
What could I earn from exporting in Yarm?
On the 12p export scenario, a 12-panel system in Yarm sends about 4,921 kWh a year to the grid, worth around £591. The export rates table compares what each supplier pays.
How does solar perform in Yarm in the winter months?
December is the weakest month in Yarm: about 180 kWh from 12 panels, against 750 kWh in May. The panels still generate on bright winter days; they just cover a smaller share of what the house uses.
How Yarm 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 Yarm |
|---|---|---|
| Yarm | 921 | this town |
| Egglescliffe | 941 | +20 kWh |
| Ingleby Barwick | 942 | +21 kWh |
| Thornaby-on-Tees | 938 | +17 kWh |
| Stockton-on-Tees | 945 | +24 kWh |
| Middlesbrough | 939 | +18 kWh |
| Billingham | 947 | +26 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.
