How Grays compares
Among the places we publish figures for, Grays is one of 46 Essex towns we track, and it ranks joint 28th of 46 for solar yield. It is a medium town in the House of Commons Library classification, with 45,535 residents, and its roofs see 2.89 peak sun hours a day across the year. That drives the standard 12 panel model to 6,710 kWh of generation, of which around 5,773 kWh is exported at 12p for £693 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 Grays's own yield, and at Grays's 1,055 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.
Thurrock is the planning authority covering Grays, which the House of Commons Library classes as a medium 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 Grays generates around 6,710 kWh a year, worth around £939 in year one on the 12p export scenario.
Generation is modelled from PVGIS satellite data for Grays's own coordinates (51.48561, 0.33239), 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.

What does a typical solar system cost in Grays?

Would a system in Grays 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 Grays before anything is booked; our G98 vs G99 guide explains the difference in full.

Same satellite dataset, same assumptions, so the differences are real geography rather than modelling noise.
