Photovoltaic support on granary roof

Can a UK roof support solar panels?

As long as your roof is pitched, has enough unshaded space, and doesn’t contain spray foam insulation underneath, it should be suitable for solar panels. The large majority of UK roofs are more than capable of supporting solar panels for as long as you need them to.

What is the ideal angle for rooftop solar panels in the UK?

The ideal angle for rooftop solar panels in the UK is around 40°. Most roofs are in this range, which allows the panels they host to capture as much sunlight as possible.

Here's how an installer will decide if your roof is suitable for solar panels, including assessing its direction, usable space, and loft.

How long do solar panels last on a flat roof?

Most UK roofs are strong enough to hold solar panels for their entire lifespan – which can last 40 years or more. This is because a solar panel system usually weighs about 20kg per square metre, which the great majority of roofs can hold. However, flat roofs may not always be strong enough for solar panels.

How many solar panels can be installed on a roof?

Your roof will need to be large enough to fit a suitable number of solar panels, as there’s rarely much point putting just two or three panels up there. The average solar panel takes up 2m², and your installer should leave around 40cm on each side of the array, as well as 3cm between every panel.
