How St Helens compares
St Helens is one of 109 Lancashire towns we track, and it ranks 28th of 109 for solar yield. The House of Commons Library settlement data classes it as a large town of 111,050 people. At 939 kWh per kWp a year, a typical 12 panel system here pays for itself in around 7.5 years on the 12p scenario: £851 of year one benefit against £6,360 of installed hardware, £247 of that benefit from cutting 26.32p imports with your own generation.
Treat these as calibration rather than a quote. The calculator below runs the same model, defaulted to St Helens's own yield, and at St Helens's 939 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.
Any planning application in St Helens sits with St. Helens, and its official House of Commons Library settlement class is large 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 St Helens generates around 5,972 kWh a year, worth around £851 in year one on the 12p export scenario.
Generation is modelled from PVGIS satellite data for St Helens's own coordinates (53.44689, -2.73455), 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 St Helens?
A typical 12 panel, 6.36 kWp system in St Helens costs around £6,360 installed, at £1,000 per kWp before any battery.
Would a system in St Helens 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 St Helens before anything is booked; our G98 vs G99 guide explains the difference in full.
