Real satellite data for Dorchester, real installed pricing, and the same honest model we run for every place we cover.
How Dorchester compares
Small towns rarely get published solar figures, so here are the numbers for Dorchester. It is one of 15 Dorset towns we track, and it ranks 2nd of 15 for solar yield, a town of 22,613 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,119 kWh per kWp a year, 3.07 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £989 of year one benefit, £247 of it from your own generation and £742 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, defaulted to Dorchester's own yield, and at Dorchester's 1,119 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 Dorset; nationally, the House of Commons Library classes Dorchester 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 Dorchester generates around 7,117 kWh a year, worth around £988 in year one on the 12p export scenario.
Generation is modelled from PVGIS satellite data for Dorchester's own coordinates (50.71026, -2.4428), 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 Dorchester
What could a roof in Dorchester generate?

What does a typical solar system cost in Dorchester?
A typical 12 panel, 6.36 kWp system in Dorchester costs around £6,360 installed, at £1,000 per kWp before any battery.
Would a system in Dorchester 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 Dorchester before anything is booked; our G98 vs G99 guide explains the difference in full.
What could I earn from exporting in Dorchester?

Where UK homes actually land, why oversizing costs you, and what shifts the band.
Read the guide →Charging an EV from your own solar
Every surplus kWh is 3.6 to 5 miles. Whether that beats a 7p overnight rate is arithmetic.

UK median installed cost around £12,908, before the up to £7,500 grant comes off.
Read the guide →The price cap explained, and what it does to solar payback
The cap limits unit rates, not bills. That changes what solar payback means.

The badge that decides whether your solar earns export payments. It cannot be added later.

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.
