Real satellite data for Southwark, real installed pricing, and the same honest model we run for every place we cover.
How Southwark compares
Southwark is one of 47 Surrey towns we track, and it ranks joint 12th of 47 for solar yield. The House of Commons Library settlement classification puts it in the core city class, with a population of 314,195, which makes it one of the largest places we publish figures for. Scale changes nothing about the physics: PVGIS gives a roof here 1,029 kWh per kWp a year, 2.82 peak sun hours a day averaged across the seasons, and on the 12p scenario about £247 of the year one benefit comes from solar you use yourself, with export income adding £673.
Treat these as calibration rather than a quote. The calculator below runs the same model, defaulted to Southwark's own yield, and at Southwark's 1,029 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.
Southwark is the planning authority covering Southwark, which the House of Commons Library classes as a core 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 Southwark generates around 6,544 kWh a year, worth around £919 in year one on the 12p export scenario.
Generation is modelled from PVGIS satellite data for Southwark's own coordinates (51.47498, -0.07542), 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 Southwark
What could a roof in Southwark generate?
PVGIS puts a roof in Southwark at 1,029 kWh per kWp a year, 2.82 peak sun hours a day averaged across the seasons.
What does a typical solar system cost in Southwark?
A typical 12 panel, 6.36 kWp system in Southwark costs around £6,360 installed, at £1,000 per kWp before any battery.
Would a system in Southwark 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 Southwark before anything is booked; our G98 vs G99 guide explains the difference in full.
What could I earn from exporting in Southwark?
On the 12p export scenario, that 12 panel system sends about 5,608 kWh a year to the grid, worth around £673. The tariff guide compares the export rates that could apply to your setup.
