Solar Stack is a product that allows us to address one of the rooftop solar industry’s greatest adversities, roof penetrations. We have sold more jobs because of Solar Stack, and see it as an amazing installation tool that is less expensive, faster to install, and higher quality than its competitors. As a cornerstone of our patent pending GreenRite® system, Solar Stack provided us an affordable, Miami-Dade NOA and Florida High Velocity Hurricane Zone certified way to design non-penetrative rooftop systems. In addition, their customer support is amazing. We are extremely happy with every experience we have had with Solar Stack!
