Can solar panels be installed on a flat roof?

Can solar panels be installed on a flat roof? The answer is yes, but flat roof solar panel installation differs from the usual sloping roof solar panels.

Many people with flat roofs decide against solar panels as they do not think they can be installed due to the lack of direct sunlight. However, they would be wrong to think that. It is actually perfectly possible to install solar panels on a flat roof as they can be angled with brackets.

What angle do flat roof solar panels need to be?

As solar panels require direct sunlight to operate optimally, the need to pair flat roof solar panels with tilted mounting brackets is required in order to ensure the flat roof solar panels can be angled towards the general direction of the sun to be sufficiently hit by sunlight.

By tilting flat roof solar panels upwards, this ensure that they capture as much sunlight as possible throughout the day. This also helps to keep each of the panels clean, as the rain will wash away dirt and debris from the surface. Typically, flat roof solar panels are mounted and angled between 10-50 degrees.

Do I require planning permission for flat roof solar panels?

Generally speaking – no, you do not need planning permission to install flat roof solar panels in the UK. There are certain requirements that need to be met however, which can be found in our solar panel planning permission blog here.
