6 FAQs about [Strength requirements for photovoltaic roof supports]

Do solar panels add weight to a roof?

Structural engineers analyze and investigate all roof structural elements to ensure they can safely accommodate the additional load of solar panels. As you probably know, the addition of solar panels adds weight to a roof structure, which can impact its integrity.

What are the new requirements for rooftop-mounted photovoltaic panels?

The new requirements imposed more complicated loading effects which the roof where the PV panels installed should meet. 2015 IBC and 2015 IRC states the following: “1603.1.8.1 Photovoltaic panel systems. The dead load of rooftop-mounted photovoltaic system, including rack support systems, shall be indicated on the construction documents.”

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.

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.

How to install solar panels on a roof?

The foremost requirement is the structural strength of the roof, which should be capable of supporting the additional weight of the solar panels and the mounting structure. The solar panel mounting structure is usually made of mild steel or aluminum, which adds minimal weight but provides adequate support to the panels 1.

What factors should a solar structural engineer consider when designing a roof?

Solar structural engineering experts pay close attention to three main factors when designing solar structures to make sure solar installations work well and last. These are – a roof’s load capacity, structural integrity and compatibility.
