Solar panel installation is possible for a homeowner, but it is not straightforward and there are several practical and safety considerations. Working on a roof can be dangerous, and incorrect installation can cause issues with wiring, waterproofing, and the roof structure. In the UK, you also need to follow electrical safety regulations and building rules, and the work may need to be signed off by a qualified electrician or a competent person scheme.
If you plan to connect the system to the grid, you will need to arrange a formal connection and ensure your setup meets the requirements of your distribution network operator. Many people choose a professional installer because they handle the design, permits, and safety checks. If you do decide to DIY, it is important to use approved equipment, follow the correct standards, and consider a professional inspection before connection.
