Frequently Asked Questions
Do solar panels work in the UK climate?
Yes, solar panels work very effectively in the UK. While we may not have the intense sunshine of southern Europe, modern panels are designed to work efficiently in diffuse light conditions. The UK receives enough solar radiation for panels to be highly cost-effective, with typical payback periods of 6-9 years.
How long do solar panels last?
Solar panels typically last 25-40 years with minimal degradation. Most manufacturers offer 25-year performance warranties guaranteeing at least 80-85% of original output after 25 years. The panels will continue generating electricity beyond this period, though at slightly reduced efficiency.
Do I need planning permission for solar panels?
Most residential solar installations fall under "permitted development" and don't require planning permission. However, you may need permission for listed buildings, conservation areas, or particularly large installations. Your installer will advise on any requirements.
What happens if there's a power cut?
Standard grid-tied solar systems automatically shut down during power cuts for safety reasons. If you want backup power, you'll need a battery storage system or a special "backup" inverter that can provide power to essential circuits during outages.
How much maintenance do solar panels need?
Solar panels require minimal maintenance. Rain naturally cleans them, and they have no moving parts to service. An annual visual inspection and occasional professional cleaning (every 2-3 years) is typically sufficient. Most systems include monitoring to alert you to any performance issues.
Can I add more panels later?
Yes, but it's often more cost-effective to install the full system initially. Adding panels later may require additional electrical work, inverter upgrades, or separate systems. Plan for future energy needs (like electric vehicles or heat pumps) when sizing your initial system.
What's the difference between panel efficiency ratings?
Panel efficiency indicates what percentage of sunlight is converted to electricity. Higher efficiency (20%+) panels generate more power per square meter, requiring less roof space. While efficiency is important, consider the total cost per watt and long-term reliability when making decisions.
Ready to Install Solar Panels?
Solar panels represent an excellent investment for UK homeowners, offering significant energy bill savings, environmental benefits, and increased property value. With 0% VAT until 2027 and improving technology, now is an ideal time to go solar.
For most homes, we recommend:
- AIKO Neostar for maximum efficiency and cutting-edge technology
