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.
The structural load of solar panels refers to the weight and forces a solar system exerts on a building or structure. This can include the weight of the panels, mounting system, and other related equipment, as well as additional loads from wind, snow, or seismic activity.
For a steel or wood low rise building, the relative additional weight from rooftop solar panels can add approximately 10% to the total factored design load of the roof structure. However, when considered in light of the total building costs, this additional costs may prove to be minimal.
By selecting the right racking and attachment systems, you can ensure the stability and longevity of your solar installation. To increase the roof capacity for solar installations to be successful, you need to consider load redistribution as a way to shift the load from weak elements to stronger ones.
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.
The larger the surface area required to support the PV system, the greater the potential impact on the building structure. The use of rooftop solar panels increases the superimposed dead load (SDL) of the roofing system and can have varying impact on a building depending on what material is being used for the structural system.
Roof Structure Design for Solar Panel Installation
The design load for a particular roof can be determined by consulting with a structural engineer. The load of a solar panel can vary depending on several factors, such as its size, type, and brand. However, on average, a standard 60 solar cells panel, measuring 1.7 square meters, typically weighs around 18 kg (equivalent to 0.10 kN/m2), while a ...

Proper Loading for Solar Panels
homeowners and commercial developers are looking to utilize photovoltaic panels (solar panels) to help get them "off the grid". It may seem that designing for solar panels is as easy as finding out how much the panels weigh, and adding point loads to their roof trusses either in the design phase, or in a repair. Unfortunately, it is not ...
