A typical 4.5kWp residential solar PV system uses around 12 panels and covers 20 to 30m² of roof space. South-facing roofs deliver the highest output, though east and west-facing roofs still generate useful electricity. LGS carries out a full site survey before any work begins, so your system is sized to your actual energy use, not a generic template
A 4kW solar panel system costs in the region of £6,600 to £8,100 installed and can save around £1,304 per year on electricity bills, with many homeowners breaking even within six years. Adding battery storage can reduce your grid electricity use by as much as 70%. LGS will provide a fixed quote, not an estimate, so there are no surprises on installation day.

Solar PV paired with a battery storage system lets you use the electricity your panels generate after dark, rather than exporting it for a fraction of the retail rate. Battery storage typically costs £4,000 to £8,000 depending on capacity and brand. LGS can advise on the right combination for your property and energy usage during your initial consultation.
