How Lewisham compares
Lewisham is one of 44 Kent towns we track, and it ranks 43rd of 44 for solar yield. The House of Commons Library settlement classification puts it in the core city class, with a population of 301,505, which makes it one of the largest places we publish figures for. Scale changes nothing about the physics: PVGIS gives a roof here 1,026 kWh per kWp a year, 2.81 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 £671.
Treat these as calibration rather than a quote. The calculator below runs the same model, defaulted to Lewisham's own yield, and at Lewisham's 1,026 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.

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 Lewisham generates around 6,525 kWh a year, worth around £917 in year one on the 12p export scenario.
Generation is modelled from PVGIS satellite data for Lewisham's own coordinates (51.44875, -0.02138), 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 Lewisham
What could a roof in Lewisham generate?

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