Performance Facts
Modern solar panels are 20-22% efficient and generate electricity from daylight, not just direct sunshine. A 4kW system produces 3,400-4,000 kWh/year in the UK — enough to cover most household electricity needs. Panels degrade just 0.3-0.5% per year.
Financial Facts
Solar panels save £500-£1,100/year on electricity bills. Payback period is 6-9 years. Solar adds 4-14% to property value. 0% VAT since April 2022. The Smart Export Guarantee pays 3-15p/kWh for surplus energy exported to the grid.
Environmental Facts
A typical home solar system prevents 1-1.5 tonnes of CO2 per year. Solar panels are 95% recyclable. The energy used in manufacturing is recovered within 1-2 years of operation. Solar is now the cheapest form of electricity generation globally.
