6 FAQs about [What should we pay attention to when using rooftop photovoltaic panels]

Is your roof strong enough for solar panels?

1. Is your roof strong enough? Some buildings, especially older ones, may not have the roof strength to support solar panels. Post 1970 structures usually have ‘W’ frame trussed roofs. These will readily support solar panels, which generally weight about 20kg each.

Can solar panels be installed on a roof?

Some buildings, especially older ones, may not have the roof strength to support solar panels. Post 1970 structures usually have ‘W’ frame trussed roofs. These will readily support solar panels, which generally weight about 20kg each. Older structures may require inter-truss strengtheners, although this is not a particularly costly procedure.

How high should solar panels be on a flat roof?

On a flat roof, the highest part of the solar PV equipment should not be more than 600mm higher than the highest part of the roof (excluding chimney). In some cases, however, permitted development rights are more limited.

Are solar panels worth it if you have a south-facing roof?
