Is my roof suitable for solar panels? [UK checklist]

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. Drilling into a flat roof can cause leaks, so an installer will usually ballast the panels instead – but these will add around 80kg per panel.
