Cornwall leads with a solar yield of around 1,039 kWh/kWp per year, followed by the Isle of Wight, East Sussex, and West Sussex. However, even the lowest-ranked UK regions exceed 750 kWh/kWp, making solar panels a worthwhile investment everywhere in the UK.

A typical 3-4kWp residential system costs £5,000-£8,000 including 0% VAT. Prices are broadly similar across the UK, though installation costs may vary slightly by region. The system pays for itself in 6-8 years through electricity savings and Smart Export Guarantee income.
