    Sunlight

    How much sun the roof actually gets.

    Unlike other solar tools, you can see with data which parts of your roof get the most sunlight over the course of the year.

We always recommend an installer survey to confirm shading, pitch, and structural suitability before you commit.

Your roof in 3D

Flat, pitched, or a bit of both?

We build a 3D model of your roof so you can see its shape and makeup for yourself. Most roofs develop character and history over time. Flat parts, different pitch angles, extensions. We try our best to make it easy to understand and improve your confidence when speaking to solar installers in your area.

A total solar eclipse, the moon's silhouette ringed by the sun's corona

Eclipse · Data

🌒 96% of the sun vanished. Britain's solar roofs shrugged.

The deepest eclipse since 1999 cost rooftop solar about 1% of the day. West-facing roofs lost five times what south-facing ones did, because they were the only ones still working at seven in the evening.
