How does structural analysis affect a rooftop solar project?

It can make or break the feasibility of the project or have significant effects on the system size and cost of racking. In this article, Pure Power's in-house structural engineering team shares the high level process involved in the structural analysis of a rooftop solar project.

How do I evaluate the structural feasibility of a roof-mounted solar project?

When analyzing the structural feasibility of a roof-mounted solar project, there are key steps to consider. You need to assess the capacity of the roof framing elements and select the appropriate racking and attachment systems to ensure that the roof structure can accommodate the PV system.

How do you assess roof framing capacity for a solar project?

1. Assessing roof framing capacity. When assessing the capacity of the roof framing elements for a solar project, it is crucial to analyze and investigate all structural elements to ensure they can safely support the additional load. This includes both new and existing roof frames.

Does pure power do structural analysis of a rooftop solar project?

In this article, Pure Power's in-house structural engineering team shares the high level process involved in the structural analysis of a rooftop solar project. We wont get into any calculations, leave that to the professional engineers at Pure Power.

How do roof mounted PV solar panels work?

Roof mounted PV Solar Panels are typically supported by racking systems which come in two basic forms. The first is a mechanically fastened system and the second, the more common of the two, is a ballast restrained system. The mechanically fastened system penetrates through the roofing membrane and can be used in pitched roofs and flat roofs.

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.”
