32.5 kW Waverly Elementary/Middle School Solar Project

Over several months, Alliance Solar and Greentech Renewables worked together to execute efficient design and complete engineering to complete this project.

There were several extra constraints due to construction happening in the area where the solar array was being designed. The school also already had plans to use a portion of the roof as a green space for the students. 

Considering there were parts of the roof that were unusable, the array had to be placed on two different surfaces to get to the desired output. The two different areas were vastly different, one was a flat membrane roof, and the other a curved metal roof. This meant that there were two separate attachment methods. Originally, it was desired to use a ballast solution for the flat portion, however, to get the tilt desired, it was going to be necessary to use a standoff. For the curved metal roof, the appropriate S-5 clamp that worked for the BEMO metal roof profile was used. 

Greentech Renewables Engineering and Alliance were able to work together to sort out all of the constraints for this project and the result was this beautiful project in Baltimore. The project featured SolarWorld modules, SMA inverters, IronRidge racking, and S-5! clamps on two different roof surfaces of this building to create the full 32.5 kW array.
