What a roof in Swindon can generate
Real satellite data for Swindon, real installed pricing, and the same honest model we run for every place we cover.
How Swindon compares
Swindon is classed as a city in the House of Commons Library settlement data, home to 191,392 people. It is one of 20 Wiltshire towns we track, and it ranks joint 14th of 20 for solar yield. Its 1,018 kWh per kWp a year works out at 2.79 peak sun hours a day, and running the standard 12 panel model here splits the return into £247 of savings from generation you use yourself and £665 of export income at 12p, with about 5,538 kWh a year going to the grid.
Treat these as calibration rather than a quote. The calculator below runs the same model, defaulted to Swindon's own yield, and at Swindon's 1,018 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.
Swindon sits within Swindon, its local planning authority, and the House of Commons Library classes it as a city.
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 Swindon generates around 6,474 kWh a year, worth around £911 in year one on the 12p export scenario.
Generation is modelled from PVGIS satellite data for Swindon's own coordinates (51.5684, -1.79044), 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 Swindon
What could a roof in Swindon generate?
PVGIS puts a roof in Swindon at 1,018 kWh per kWp a year, 2.79 peak sun hours a day averaged across the seasons.
What does a typical solar system cost in Swindon?
A typical 12 panel, 6.36 kWp system in Swindon costs around £6,360 installed, at £1,000 per kWp before any battery.
Would a system in Swindon 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 Swindon before anything is booked; our G98 vs G99 guide explains the difference in full.
What could I earn from exporting in Swindon?
On the 12p export scenario, that 12 panel system sends about 5,538 kWh a year to the grid, worth around £665. The tariff guide compares the export rates that could apply to your setup.

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.
