Get stamped structural calculations for racking, roof loading and foundation design. Solar structural engineering services built per site on Sunhub.
Wind, snow and seismic loading get calculated against the project's actual location and structure, since a generic load table is exactly what gets flagged in jurisdictions with stricter structural review.
Attachment point analysis for rooftop systems and pile or footing design for ground-mount projects are both in scope, engineered to the racking system actually being installed.
PE stamping requirements vary by state and by project scale, and calculations here are delivered stamped where the specific jurisdiction requires it.
Site-specific load calculations replace a generic table that draws scrutiny in stricter jurisdictions.
Stamping requirements get matched to the specific state and project scale before submission.
A stamped structural calculation is typically required when the AHJ needs proof the roof or foundation can carry the added solar load, which is common for ground mounts, older or marginal roofs, and most commercial jobs. Some residential roofs pass on prescriptive tables, but many jurisdictions still ask for a stamp. Sunhub provides calculations engineered to the specific site and stamped for the jurisdiction that requires it.
Yes. Roof-mount analysis centers on attachment points, member capacity, and how the array loads the existing structure, while ground-mount work focuses on foundation design, pile embedment, and soil conditions. Both must handle site-specific wind, snow, and seismic demands. Sunhub covers roof-mount and ground-mount alike, engineered per site rather than from a generic load table.
Analysis generally accounts for dead load, live load, wind uplift and pressure, snow load, and seismic demand, all set by the site's location and building code. The attachment itself is checked for pull-out and shear at each connection to the structure. These factors drive both the racking spacing and the fastener spec.
