Can solar panels be installed on rafters or trusses?

Whether your roof is constructed with rafters or engineered trusses, both can be good fits for solar panels. Both rafters and trusses provide significant structural integrity for a solar panel installation, and most solar companies have significant experience installing on both types of roof supports.

How do you install a solar PV system on a roof?

Roof anchors have staggered fixing so work must be done (widen or fit noggins) before installing PV onto such narrow timbers. On-roof is the most common type of way when retro-fitting a solar pv system to your home, and there are many different manufactures of mounting systems but thankfully the correct way of installing them is the same.

Can a photovoltaic system replace roof cladding?

It is possible for photovoltaic systems to replace roof cladding entirely. This is known as a solar or energy roof. Additionally, PV modules can be integrated into the roof cladding. Solar roof tiles are a special type of in-roof installation. They can be integrated into the existing roof cladding without any extra mounting systems.

What factors should you consider when installing roof-mounted solar panels?

One of the most important factors when installing roof-mounted solar panels is the condition and structure of the roof. It’s vital that a roof be able to not only hold up the weight of the solar panels, but also withstand any wind loads that could pull on the roofing.

How do I calculate the structural load of solar panels on a roof?

To calculate the structural load of solar panels on a roof, several factors must be considered, including the number and weight of the panels, the weight of the mounting system and components, and any additional loads from wind, snow, or seismic events.

Do solar panels need roof reinforcements?

Roof reinforcements may be necessary for some installations, depending on factors such as the roof's strength, the weight of the solar system, and local building code requirements. A structural engineer can evaluate the roof's condition and determine whether reinforcements are needed to support the additional load of the solar panels.
