TP-4 Adjustable Triangle Solar Mounting System (9)

The Yuens TP-4 Adjustable Triangle Mounting System is designed to accommodate both flat and sloping metal roofs. Its rear support rack allows the adjustment of the tilt angle, making it versatile for various installations. The unique installation method, coupled with durable support racks and rails, ensures system stability and simplifies the installation process. With high-quality components and fewer spare parts, it offers an efficient solution for large-scale solar projects.

1. Precast Concrete Base Foundations

Before beginning, ensure you have all the required tools and components on hand. Mark the positions of the concrete bases according to measurements L1 and L2 on your construction drawings. Ensure that all concrete bases are aligned both horizontally and vertically. Embed anchor bolts in the concrete base at a distance of 80±0.5mm for secure installation.

2. Install the legs

Start by attaching the adjustable front and rear legs to the concrete base. Secure them using M8 nuts, ensuring the legs are firmly fastened.

3. Install the Rail

(1) Rail Connection

If the rails are not long enough, you’ll need to connect them using rail splices (otherwise skip this step). First, insert one end of the rail splice halfway into the first rail and secure it with an M8x12 hex bolt. Then, insert the remaining half of the rail.

4. Install the Solar Panel

Suggest to start the installation from left side of the bottom. 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.

All dimensions and installation details should strictly follow the provided construction drawings. This guidance is for descriptive purpose of installation only.

Stainless steel fasteners

Stainless steel material is quite different to carbon steel with its excellent ductility. It would be unable to unscrew the bolt and nut after matching in case improper use. That is “lock up”, known as “dead lock”. Methods to avoid lock up as below:

Reduce the friction coefficient

  • Make sure the surface of threads to be clean (without dusts or clutters);
  • Suggest to apply water wax or lubricant on surface for installation (such as butter or 40# machine oil)

Use correct operation method

  • The bolt must be perpendicular to the axis of thread when screwing. Do not lean the bolt;
  • Apply the force evenly when tightening and the tightening torque should not exceed the specified secure torque value;
  • Using torque wrench or socket spanner as far as possible, avoid using monkey wrench or electric wrench; Adjust the rotational speed as low as possible when using electric wrench;
  • Avoid high temperature. To avoid lock up which caused by sharply increasing temperature, do not rotate rapidly. (like using electric wrench)
