Recommended Clamping Zones for Solar Panel Installations
WINAICO solar modules are suitable for both vertical and horizontal installation methods due to their high degree of stability.
The modules must be clamped in place at a minimum of 4 points to make sure external pressure is distributed evenly across the panels.
The following clamping zones aim to illustrate the correct areas (highlighted in green) for placing mounting points for solar panels.
Please be aware that the images are not to scale and accurate measurement is required during installation.
Test load = 1.5 x design load.

The Orientation of the Solar Panel Junction Box
The modules must always be installed with the junction box either parallel with the ground if mounted horizontally or at the top of a panel if situated vertically.
Mounting Clamps and Screws
The modules can be mounted on the substructure by clamps from the front or by screws from behind.
The middle clamps can be used as spacers between the module rows when mounting the modules.
Please use the existing drilled holes on the frame for securing the module.
Do not drill any additional holes, as it will void the product warranty.
To avoid any possible stresses and failure to comply with dimensions, a gap should be maintained between the module rows.
WINAICO recommends a gap of approximately 2 cm, but please refer to your mounting systems installation manuals.
For aesthetic reasons, we recommend using black clamps for mounting our module series with a black anodised frame and black backsheet.
When the aluminium frame is mounted on a bracket of different metal material, the two metal parts should be isolated to avoid galvanic corrosion, especially in humid or coastal areas.
Do not touch live terminals with bare hands, and always use insulated tools for electrical connections.
