How Tonbridge compares
Among the places we publish figures for, Tonbridge is one of 44 Kent towns we track, and it ranks joint 28th of 44 for solar yield. It is a medium town in the House of Commons Library classification, with 37,210 residents, and its roofs see 2.88 peak sun hours a day across the year. That drives the standard 12 panel model to 6,684 kWh of generation, of which around 5,748 kWh is exported at 12p for £690 a year, with £247 saved on electricity you would otherwise buy at 26.32p.
Treat these as calibration rather than a quote. The calculator below runs the same model, defaulted to Tonbridge's own yield, and at Tonbridge's 1,051 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 Tonbridge generates around 6,684 kWh a year, worth around £936 in year one on the 12p export scenario.
Generation is modelled from PVGIS satellite data for Tonbridge's own coordinates (51.19918, 0.28144), 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 Tonbridge
What could a roof in Tonbridge generate?

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