# Rooftop vs ground-mounted solar for business

Rooftop solar is the usual choice for businesses because it uses space you already have and puts generation right where the power is used. Ground-mounted solar suits sites with limited or unsuitable roofs but spare land, and can host larger arrays — though it needs the land and often planning permission.

## Rooftop solar

Mounting panels on your existing roof uses otherwise dead space, keeps generation close to your demand, and often falls under permitted development. For most commercial buildings with a sound, reasonably unshaded roof, it is the simplest and most cost-effective option.

## Ground-mounted solar

Where a roof is small, shaded or structurally unsuitable, a ground-mounted array on spare land can work — and can be scaled larger than a roof allows. It typically needs available land, usually requires planning permission, and involves groundworks, so suitability depends on the site.

## Which is right for you

If you have a good roof, start there. If your roof is limited but you have land, ground-mount is worth exploring. Some sites combine both. We assess your roof, land, demand and connection to recommend the best mix.

## Frequently asked questions

**Is ground-mounted solar more expensive?**

It involves groundworks and usually planning, so the balance of costs differs from rooftop, but it can host larger systems. The right choice depends on your site — we compare the options for you.

**Can I have both roof and ground-mounted solar?**

Yes, some sites use both to maximise generation. We design around your roof, available land, demand and grid connection.
