Is solar worth it in St Helens?
St Helens, located in North West, gets enough annual sunlight to make solar installation worthwhile for most south-facing roofs. The good-suitability rating reflects the UK's overall solar irradiance levels for the region, which translates to around 850–1,050 kWh per kWp of installed capacity per year.
With typical housing in St Helens dating to the pre-1940 era, most homes have pitched roofs suitable for standard panel mounting. A typical 4kW installation on a semi-detached home generates 3,400–4,000 kWh per year — enough to cover 60–80% of a medium-usage household's electricity.
Under the Smart Export Guarantee (SEG), you're paid for every kWh you export to the grid. Most suppliers pay 3–15p/kWh. Combined with self-consumption savings, a 4kW installation typically pays back in 8–12 years and has a lifespan of 25+ years.
