How Seaham compares
Small towns rarely get published solar figures, so here are the numbers for Seaham. It is one of 35 Durham towns we track, and it ranks 3rd of 35 for solar yield, a town of 21,939 people in the House of Commons Library settlement data. PVGIS gives its roofs 978 kWh per kWp a year, 2.68 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £881 of year one benefit, £247 of it from your own generation and £634 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, defaulted to Seaham's own yield, and at Seaham's 978 kWh per kWp it 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.
Planning applications here go through County Durham; nationally, the House of Commons Library classes Seaham 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.

A 12 panel, 6.36 kWp system in Seaham generates around 6,220 kWh a year, worth around £881 in year one on the 12p export scenario.
Generation is modelled from PVGIS satellite data for Seaham's own coordinates (54.8363, -1.35016), using the same 26.32p/kWh import value and £1,000 per kWp installed pricing as every Clearline estimate, with the full methodology, sourcing and assumptions set out on our help page.

Common questions about solar in Seaham
What could a roof in Seaham generate?
PVGIS puts a roof in Seaham at 978 kWh per kWp a year, 2.68 peak sun hours a day averaged across the seasons.
What does a typical solar system cost in Seaham?
A typical 12 panel, 6.36 kWp system in Seaham costs around £6,360 installed, at £1,000 per kWp before any battery.
Would a system in Seaham need a G99 application?
Most home solar and battery systems qualify for the simpler G98 notification, made to the network operator (DNO) after installation rather than before. A minority, usually larger systems, need the fuller G99 process instead. Your design call checks which applies in Seaham before anything is booked; our G98 vs G99 guide explains the difference in full.
What could I earn from exporting in Seaham?
On the 12p export scenario, that 12 panel system sends about 5,283 kWh a year to the grid, worth around £634. The tariff guide compares the export rates that could apply to your setup.

Solar panel types, and the four numbers that actually matter
TOPCon, HJT and back contact decoded, plus the four numbers worth comparing.
Read the guide →Adding a battery to solar panels you already own
Retrofitting a battery to working solar is straightforward. The paperwork is where people trip up.
Read the guide →What it really costs to charge an EV at home versus in public
Home off-peak charging costs a fraction of the public price. The arithmetic, and the tariff it depends on.
Read the guide →Heat pump running costs versus a gas boiler, assumptions shown
Four numbers decide it: seasonal efficiency, flow temperature, tariff and heat demand.
Read the guide →Why tariff choice moves payback more than kit choice
Identical kit, five times the export income. The tariff decision worked through with August 2026 rates.
Read the guide →G98 or G99: which one applies, what the application involves, and how long it takes
The G98 line sits at 3.68kW per phase. Above it, your network operator has to say yes first.

Same satellite dataset, same assumptions, so the differences are real geography rather than modelling noise.

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.
