While roof mounted solar systems are not terribly heavy, they can dramatically change the way snow loads are applied to your roof structure. They are also a potential source of expensive wind-borne debris if not fastened down adequately. In addition, both residential and commercial roof structures are typically designed very efficiently, leaving little room for the application of unplanned-for components. Your roof structure should be carefully analyzed prior to selecting or installing a solar system. The analysis should not only consider the strength of your roof, but also how to physically attach the solar system so that it stays where you want it.

Because of our residential and commercial design experience, we are familiar with almost all types of roof construction, loading (snow and wind), and are fully qualified to evaluate your existing structure. We can provide recommendations for support and connections using the most popular products. It is common for building departments to require a letter from a licensed structural engineer indicating that a structure has the capacity to support a planned solar installation.

AEI has also provided design and analysis for solar racking companies, checking aluminum extrusions for strength and stiffness, as well as designing free-standing support systems for residential to utility size projects.
