How Pier Analysis Beats Slope Analysis When Deploying Ground-Mount Solar on Uneven Terrain

In Press Clips by

To determine whether a mounting system can be installed on a site with uneven terrain, most developers have relied on slope analysis — or the computation of the average grade underneath each tracker or table. Slope analysis doesn’t take the post height limitations into account, however, and going beyond slope analysis to model every post in a utility-scale layout was too time consuming to be practical. Now, thanks to advances in modern cloud computing and data analytics, pier analysis is possible for the first time, increasing the accuracy of project modeling and site assessment, reducing both material and manpower costs…
