About Seismic protection measures for photovoltaic panels
The 2016 edition of ASCE 7 has been in effect for about three years. It has three more years remaining before the standard is superseded by ASCE 7.
The 2022 edition of ASCE 7 includes an update to Section 13.6.12 that says, “The solar panels shall not be considered as part of the load path that resists the interconnection force unless the panels have been evaluated or.
Research by the Structural Engineers Association of California (SEAOC) formed the basis for key provisions of ASCE 7-16. See the following white papers for research on seismic.
Cain identified several code development issues for SEAC to monitor. Strong guidance exists for low-profile systems on low-slope roofs. However, Cain is keeping an eye on the edge factor.Find out how the ASCE 7 standard affects wind load, seismic load, and tornado load considerations for solar photovoltaic (PV) systems. At SEAC’s February general meeting, Solar Energy Industries Association Senior Director of Codes and Standards Joe Cain presented an update on structural load requirements affecting solar photovoltaic (PV .

This paper describes the key seismic considerations related to this innovative method of PV installation on flat or near-flat building rooftops, and presents a rational approach for the evaluation of PV array seismic sliding displacements and determination of corresponding gaps for seismic movement.
Seismic SEAOC developed a draft document that addresses the seismic hazards associated with rooftop PV systems; “Structural Seismic Requirements and Commentary for Rooftop Solar Photovoltaic Arrays” (SEAOC Report PV1-2012). The seismic requirements document is applied to the three types of PV systems; unattached.
Solar panel installations in areas with high seismic activity require additional structural reinforcement to withstand potential earthquake forces. Proper seismic design, according to building codes and requirements, can help maintain the stability and safety of the solar installation during an earthquake.
Design provisions for rooftop-mounted photovoltaic panels and their attachments are included in ASCE 7-16 Section 13.6.12 for seismic loading and in ASCE 7-16 Chapters 29 through 31 for wind loading.

6 FAQs about [Seismic protection measures for photovoltaic panels]
Do ground-mounted photovoltaic (PV) modules have seismic performance?
Policies and ethics This paper presents the seismic performance of ground-mounted photovoltaic (PV) modules. The seismic performance of the PV module is evaluated for sets of near-field (NF) and far-field (FF) ground motion records.
Are solar panels earthquake-resistant?
For seismic design, analysis is relatively straightforward for positively attached systems to the ground or roof structure. This design methodology for assessing the structural adequacy of separate solar arrays under seismic load is studied. Earthquake-resistant construction is meant to safeguard PV systems from earthquakes.
How is the seismic performance of a PV module evaluated?
The seismic performance of the PV module is evaluated for sets of near-field (NF) and far-field (FF) ground motion records. The selected ground motions are matched to the target spectra in IS-1893 (Part-I):2016 for different soil conditions and seismic intensities. The varied capacity and supporting module systems are considered in the analysis.
How is seismic analysis done in a ground-mounted PV module?
The seismic analysis of the ground-mounted PV module is done for various seismic conditions. The NF and FF real ground motions are selected to perform the time history analysis. The desired ground motions are matched to the target spectra given in Indian Standard Code IS-1893:2016 (part 1).
What are solar photovoltaic design guidelines?
In addition to the IRC and IBC, the Structural Engineers Association of California (SEAOC) has published solar photovoltaic (PV) design guidelines, which provide specific recommendations for solar array installations on low-slope roofs 3.
What are the structural requirements for solar panels?
Structural requirements for solar panels are crucial to ensure their durability, safety, and efficient performance. These requirements vary depending on the type of installation, such as rooftop or ground-mounted systems, as well as the specific location and environmental factors.
