While ASCE 7-16 does provide recommendations regarding soil and seismic issues that impact number and placement of piers in Ground Mount arrays, the changes don’t impact rail spans, about which we provide direction. These changes will impact all rooftop arrays, regardless of the slope. Will this impact just Pitched Roof, or are Flat Roof and Ground Mount arrays going to change? You can design a project to ASCE 7-16 standards. Additionally, we’ve updated our Design Assistant tools to accommodate the new design considerations and algorithms. Visit the Pitched Roof Documents & Resources page for the most up-to-date links. We’ve published sealed certification letters for most solar states, and will be adding new state-specific letters as they transition to ASCE 7-16. How is IronRidge® supporting installers with ASCE 7-16? To be safe, contact your AHJ about their roll-out timing. By the end of 2020, most cities will have moved away from 7-10 standards. Some municipalities like Larimer, Colorado have already begun issuing permits based on ASCE 7-16 code.
