Tools and equipment
Components
Installation steps
1. Install the tile hooks
Please prepare all the needed tools and related products before the installation. Mark positions of all the hooks according to the construction drawing. L1 normally equals half-length of solar panel. L2 equals the span length of hooks, which is the same as the construction drawing. Please make sure that all the hooks be aligned horizontally and vertically, and ensure the tile hook is placed on the roof wooden rafter and fixed with wood screws.
2.Install the rail
(Connect the rails with rail splice if the rails are not long enough, otherwise skip this step) Insert the rail splice half into the first rail and then fix it with 1pc M8x12 hex bolt. Then insert the other half of rail splice into the second rail, match them together and then fix them with 1pc M8x12 hex bolt as well. Then the first and second rails are connected.
Fixing the rail on hook by Z nut kit.
3.Install the solar panels
Suggest to start the installation from left to right. Each mid clamp needs to be equipped with one grounding washer. Two end clamps of each array/line need to be equipped with two grounding lugs.
Installation Notes
1. Size Considerations
Always refer to the construction drawing for precise dimensions. This guide provides general instructions and should be used for reference during installation.
2. Stainless Steel Fasteners
Stainless steel differs from carbon steel due to its excellent ductility. If used incorrectly, bolts and nuts can get stuck, a problem known as “lock-up” or “deadlock.” Here are some tips to avoid this:
(1) Reduce Friction:
Ensure the threads are clean and free from dust or debris.
It’s recommended to use water wax or a lubricant (such as butter or 40# machine oil) during installation.
(2) Proper Operation:
Make sure the bolt is aligned perpendicular to the axis of thread when screwing. Do not lean the bolt.
Apply even force when tightening, and don’t exceed the recommended torque value.
Use a torque wrench or socket spanner whenever possible. Avoid using a monkey wrench or electric wrench, and if using an electric wrench, keep the speed low.
Avoid high temperatures. Fast rotation can cause a sharp increase in temperature, leading to lock-up.
