We used Solar Stack for the first time at a commercial multi-family project on the West coast of Florida. Solar Stack was perfect for this installation as the number of obstructions and rooftop HVAC equipment made it very difficult for us to design a ballasted system without the necessary use of many penetrating attachments into the roof. Beyond that, Solar Stack allowed us complete the installation more efficiently and quickly than any other flat roof racking product we’ve ever used. By eliminating the ballast blocks from our material list for this project, we were able to save a ton of money on labor and the small crew we had working the job was ecstatic that they didn’t need to carry concrete blocks from one side of the roof to the other! We certainly look forward to using Solar Stack again in the near future!
