New webinar available! Testing reveals the strength of residential roof structures for solar installations

September 8, 2015

Are structural engineering analyses a requirement for PV permits in your area? Are they required even on newer construction? Do you ever wonder whether this step is really necessary?

The rooftop solar PV permitting process varies greatly, even between neighboring cities. Inconsistencies between jurisdictions can cause difficulties for solar installers who work across boundaries, adding sizable permitting costs and delays that may not be required in neighboring jurisdictions.

To address this issue, Sandia National Laboratories conducted a series of tests funded by the U.S. Department of Energy’s SunShot Initiative to evaluate the structural behavior of common residential roof structures. The effort involved a wide range of destructive tests on numerous scaled wood structures to produce and capture data on actual rooftop load capacity.

Join Sandia National Laboratories researcher Stephen Dwyer and the Solar Instructor Training Network to learn how testing results demonstrate most rooftops are sufficiently strong to accommodate PV installations. Learn which building practices increase rooftop strength by up to 74 percent, and why the most common process used for rooftop structural analysis fails to produce a realistic reflection of the ability of most rooftops to sustain PV loads.
