What clamps do I need to install solar panels?

Top-mount clamps are the most common attachment method, and support modules between .9" and just over 2.0". Know the thickness of your modules and pick the corresponding end clamps, mid clamps or cap strips for the finishing part of the install. SolarTown offers all the necessary clamps or cap strips to support your installation.

How do you clamp a solar array?

Then select an end-clamp and mid clamp or a cap strip to hold the panels down. End clamps install on the outer edges of the array, and mid clamps install between columns of panels. A cap strip is an alternative that functions as a clamp, but gives a sleeker look for the array as a unit.

How many end clamps do I Need?

The number of end clamps required is equal to one less than the number of modules on each row. For nine modules, I need eight mid-clamps for each rail. As I have four rails, I need 32 mid-clamps. The module thickness is also important here.

How to install a cross connector clamp?

According to the installation plan, determine the mounting position and orientation of the Cross Connector Clamp depending on rails running parallel or perpendicular to the roof rib, then fasten the bolt with 16-20 N•m torque.

What is the difference between end clamp and cap strip?

End clamps install on the outer edges of the array, and mid clamps install between columns of panels. A cap strip is an alternative that functions as a clamp, but gives a sleeker look for the array as a unit. Cap strips come in lengths to match the rails you've chosen.

How do I use Kalzip® clamps?
