Most properties in the UK are suitable for a solar panel system. However, to get the best results from your system you should have a minimum of 16 square metres or roof space, ideally facing between south east and south west, and be free of shade. For best performance they should be angled at 30 to 40 degrees – although you will still catch a reasonable level of sunlight at angles of 20 – 50 degrees.
Shade falling on the roof will reduce the performance. How much it affects it by depends on type of shading: close structures such as gable windows or chimney stacks can reduce output significantly as they will tend to throw shade on the panels for most of the day. Further away objects such as trees or a neighbouring house may not block the sun during summer, but create shade when the sun is lower in the sky in winter.
Solar PV systems are easy to install, need virtually no maintenance and are estimated to last 40 years. They are suitable for use in urban areas which wind or hydro systems don’t tend to be.
Planning permission for solar panels
Solar panels are generally considered ‘permitted development’ in England and Wales as long as they are not installed above the ridge line of your home. However, if you live in a listed building or in a conservation area, restrictions will apply. Up-to-date advice is available on the government’s planning portal.
GEM Solutions survey process
As part of our survey process we will check the suitibility of your property and calculate the most efficient use of your roof to enable you to achieve the best results from your system. In addition we can contact your local planning department on your behalf to seek clarification on any planning permission that may be required should your property fall into one of the above exemptions.
