Please see the video on how to adjust the Frame and Clamp space 

Frame Space:

Frame space, refers to the gap or clearance between adjacent solar panel frames when multiple panels are installed side by side. This space allows for thermal expansion and contraction of the panels without causing damage or warping to the frames. Proper frame spacing is essential to prevent mechanical stress and ensure the longevity of the solar panel array.

Clamp Space:

Clamp space refers to the area on the solar panel frame where clamps are attached to secure the panel onto the mounting structure. This space is crucial for ensuring proper attachment and stability of the solar panels to the mounting system. The size and dimensions of the clamp space may vary depending on the design of the solar panel frame and the type of mounting system being used.

Both clamp space and frame space are important considerations during the design and installation of solar panel systems to ensure proper mounting, structural integrity, and optimal performance of the solar panels over their operational lifetime.
