Solar panels convert sunlight into electricity through photovoltaic cells. When sunlight hits these cells, it creates an electric field that generates direct current (DC) electricity. This DC electricity is then converted to alternating current (AC) by an inverter, making it usable in your home.

Most solar panels come with a 25-year warranty and can continue producing electricity for 30-35 years. The inverter typically needs replacement after 10-15 years. UK weather conditions are well within the operating parameters of quality solar panels.

The actual installation usually takes 1-2 days for a typical domestic system. However, the entire process, including surveys, MCS certification paperwork, and DNO (Distribution Network Operator) notification, typically takes 4-6 weeks.

Most domestic solar installations in the UK are considered “permitted development” and do not require planning permission. However, you may need permission in certain cases such as if your property is listed or if you live in a conservation area. Also in certain cases if the installation would protrude more than 200mm from the roof or if the panels would be higher than the highest part of the roof.

A typical 3.5kW system requires about 20-25 square metres of roof space. The exact amount depends on panel efficiency and your energy needs.

Standard grid-tied systems will shut down during power cuts for safety reasons. If you want backup power, you’ll need to install a battery storage system with specific cut-out functionality.

Yes! Solar panels do not need direct sunlight to work – they still generate electricity on cloudy days. The UK receives about 60% of the solar energy compared to equatorial regions, and modern panels are efficient enough to make good use of our available sunlight.
