Frequently asked questions

How much can I save with solar panels?

Savings depend on your electricity usage, roof size, system size, and whether you add battery storage. Many homeowners reduce their electricity bills significantly by using solar power during the day and storing excess energy for later.

Do solar panels work in the UK?

Yes. Solar panels work from daylight, not just direct sunshine, so they still generate electricity on cloudy days. Output is higher in spring and summer, but panels continue producing energy throughout the year.

Do I need a battery with my solar panels?

A battery is optional, but it can help you use more of the electricity your panels generate. Without a battery, unused power is normally exported back to the grid. With a battery, you can store it for evening or night-time use.

How long does a solar installation take?

Most standard home solar installations take around 1–2 days once scaffolding and materials are ready. Larger or more complex systems may take longer.

Will solar panels work during a power cut?

Most standard solar systems automatically shut down during a power cut for safety reasons. If you want backup power, you’ll need a suitable battery and backup/UPS setup designed for that purpose.

Do solar panels need much maintenance?

Solar panels require very little maintenance. They have no moving parts, and rain usually helps keep them clean. We recommend periodic checks to make sure the system is performing properly.

How long do solar panels last?

Most solar panels are designed to last 25 years or more. Inverters and batteries may have shorter lifespans and may need replacing during the lifetime of the system.

Do I need planning permission for solar panels?

Most residential solar installations fall under permitted development, so planning permission is usually not required. However, rules can differ for listed buildings, conservation areas, flats, and unusual roof layouts.

Can solar panels increase my property value?

Solar panels can make a home more attractive by reducing running costs and improving energy efficiency. The exact impact on value depends on the property, system quality, and buyer preference.
