Solar Mounting on Standing Seam Metal Roofs
Small and medium-sized commercial buildings frequently have metal roof tops with standing seams. The feet of the solar rack is a base clamp—such as those manufactured by S-5! Attachment Solutions—that fastens securely to the seam. The rack structure is secured to the base clamp without penetrating the metal roof. Metal standing seam roofs provide for fast and efficient solar mounting.
The overall solar rack can be mounted flush to the roof where the solar array slope matches the roof slope, or rear legs can add a tilt angle to the solar panels for greater energy production.
Tilted solar arrays require a space between rows to prevent rows from casting shadows onto the following rows. These also deserve structural engineering review to ensure the metal standing seam roof and underlying structure can withstand the higher wind load from the array. However, the use of wind deflectors can mitigate these forces considerably. The images to the left illustrate the points above.
