1. How much do solar panels cost in the UK?

2. How much can I save on my electricity bills?
Savings depend on your household energy usage, roof orientation, and the size of your system. On average, UK households can save around £200–£400 per year. If you use a lot of electricity during the day when your panels are producing energy, savings can be even higher.
3. Do solar panels work in the UK’s cloudy weather?
Yes! Modern solar panels are designed to work efficiently even in low-light conditions. While they generate less electricity on cloudy days compared to sunny days, they still produce enough energy to make a noticeable difference to your bills.
4. How long do solar panels last?
Panels generally have a 25-year performance guarantee but can continue producing energy for 30+ years with minimal maintenance.
5. Do I need planning permission?
Most domestic installations don’t require planning permission. Exceptions include listed buildings, conservation areas, and some flat roofs. Check with your local council.
6. Can I sell excess electricity back to the grid?
Through the Smart Export Guarantee (SEG), you can sell surplus electricity and earn extra income. It’s a great way to maximize the financial benefits of solar.
7. Will solar panels increase my home’s value?
Yes. Energy-efficient homes are more attractive to buyers. Solar panels can increase property value while reducing ongoing energy costs.
8. What maintenance do solar panels need?
Minimal maintenance is required. Panels are weather-resistant and only need occasional cleaning and inspection.
9. Are solar panels suitable for all roof types?
Pitched roofs, especially south-facing, are ideal. Flat or partially shaded roofs may require angled mounts or microinverters. A professional assessment ensures optimal performance.
10. How long to recoup installation costs?
UK homeowners usually recoup costs in 6–12 years. After this, electricity is effectively free, and you continue enjoying savings for decades. Find out about ROI here.
