Photovoltaic panels can be installed beyond the eaves

Can solar panels be installed in the edge zone?

Solar panels can still be installed in what they call the edge zone, provided the rails that panels are clamped to have around twice as many attachment points to the roof as the rails in the internal zone. So provided rails are fastened as the installation manual recommends, panels can be installed up to the edges of roofs.

Are solar panels allowed on a roof?

Depending on the roof mounting system used to attach the panels, there may be ‘exclusion zones’ where no solar panels are allowed. These zones exist because winds are strongest around the edges of roofs. Installing away from the roof edge reduces wind loading on the panels and makes them less likely to be damaged or even torn off in a storm.

Do I need eaves to ridge protection for a PV array?

If the array is less than 1m from the edge of the roof, then edge protection running from eaves to ridge will be required in all cases. Platform length: Platform must run at least 1m beyond the sides of the PV array or to the edge of the building, whichever is shorter. Ladder: Ladder access to the platform is preferably at the end of the platform.

Do solar panels need a roof edge?

Even when manufacturer guidelines don’t require it, installers still need to leave enough space at the bottom edge of a roof so water flowing down solar panels doesn’t overshoot the gutter. It is also good practice to leave at least 20cm between panels and roof edges.

What are the edge protection requirements for a PV array?

Edge protection requirements: Either, platform must extend at least 1.5m beyond the outer edge of the PV array, or, double handrail edge protection outside of the PV array edge running from eaves to ridge. If the array is less than 1m from the edge of the roof, then edge protection running from eaves to ridge will be required in all cases.

Can photovoltaic panels be installed in-roof?

It can be designed and used to cover the whole roof if required, subject to panel and roof size. Photovoltaic panels installed in-roof using GSE can be positioned in portrait or in landscape. The system can be installed on wood or metal structures and mounted on battens. It is possible to install GSE in-roof on slopes between 12° and 50°.
