The American Society of Civil Engineers (ASCE) 7-16 Code is the latest code update that solar manufacturers and installers must abide by. Most states have adopted it and the rest will soon follow, so its important to understand what it entails.
First off, it's important to note that the International Building Code (IBC) 2018 is identical to ASCE 7-16. Also, be aware that some states will take the new national standards and add to it to create their own regional standards, such as CBC 2019 for California. Just remember if you hear any of these acronyms - the most up to date code compliance is in discussion.
Below we point out a few examples of what changes are added to the ASCE code.
With the growth of rail free systems on roofs, UL has updated their code to include railless or rail free systems. The code states that if a module is removed from an array and it breaks the bonding path, then it is not in line with UL 2703 standards. Therefore, it is much more beneficial to stick to a traditional rail system such as Everest's CrossRail systems.
