Can solar panels be installed on a roof?

"The solar panels will need to be mounted on the roof by installers who understand roofing and will need some scaffold decks to safely get the panels to the roof.

Should solar panels be installed on a south-facing roof?

Ideally, your solar panels will be installed on a south-facing roof at an angle of about 30°. These are the optimal conditions for solar panel production. The closer you get to this, the more electricity your panels produce. Solar panels with a larger power-to-size ratio will produce more electricity per square foot.

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.

Will my roof generate solar energy?

Realistically, your roof’s solar generation potential will be less than that. It’ll likely still exceed your typical household energy needs, but real-world constraints like roof space, sunlight exposure, and equipment specifications play a huge role in your panels’ actual generation.

Can solar panels be mounted on a flat roof?

For solar panels on a flat roof, mounting systems are slightly different and can include a triangle 'ballast' box to support the panels. For solar thermal panels (with cells that use the sun's heat to warm water in a house) things are a little different.

Do solar panels damage your roof?

Solar panels do not typically damage your roof, but they do exert additional weight on the existing structure. This is because they are usually mounted via panel hooks or similar devices.
