How Solar Panels Work in the UK
Many UK homeowners are surprised to learn that modern solar panels work effectively even during cloudy weather – they generate electricity from daylight, not just direct sunshine. Your panels power your home directly, reducing what you buy from the grid, while excess energy gets sold back through the Smart Export Guarantee.
With today’s advanced technology and installation costs at historic lows, many homeowners find their solar panels pay for themselves within 8-12 years through energy bill savings.

Additionally, the Smart Export Guarantee (SEG) allows homeowners to earn money by selling excess electricity back to the grid, providing ongoing returns on your investment.
