recommended minimum specifications, which are intended to be guidelines and not absolute design requirements: A module surface contact length of 70mm [2.76 inches] (80mm [3.15 inches] preferred).
The screw to be used is dimensioned with an allowance due to the elongation of the anchor during assembly. For the hole depth of blind holes at least 10 mm allowance has to be added to the anchor.
Trina suggests using M8 bolts to fix the clamp. The torque for M8 screw is 16-20 N*M. When choosing the bolts and nuts for the clamp, please note your racing’s dimensions first. Aluminum frames limit the screws fastening. As shown below, the screw cannot fasten downwards. In this case, the T type of cap is recommended.
One of the most common fasteners used in solar installation is the 5/16 x 3-1/2” (18-8) stainless steel lag bolt, sometimes referred to as a lag screw. These fasteners were created to connect larger pieces of lumber together, but solar installations often require lag bolts to secure roof mounted systems directly onto the roof’s structure.

In photovoltaic systems, a variety of different types of fasteners can be employed depending on their function and application scenario. Below, we delve into several commonly used fasteners and their characteristics: a. Screws and Bolts
What is the importance of fasteners in photovoltaic installations?
Fasteners hold a pivotal role in photovoltaic installations. While they might not be as conspicuous as solar panels or inverters, their function is paramount. Here’s an in-depth look at the significance of fasteners: a. Ensuring Structural Integrity Fasteners are crucial for firmly connecting solar modules, mounts, and other components.
How far should a clamp be connected to a PV module?
Clamps should be connected to the module between 300 and 400 mm from the edge of the module. This distance is from the module edge to the middle of the clamp. *Note: Need two support rails below the PV module to make sure the Mechanical load. *Note: The above-described distance is from the module edge to the middle of the clamp.
How many PV modules can be connected in series?
nt and voltage. PV modules connected in series should have similar current, and modules must not be connected together to create a voltage higher than the permi ted system voltage. The maximum number of modules in series depends on system design, the type of inverter used and envir
What is the tilt angle of a PV module?
ilt Angle SelectionThe tilt angle of the PV module is measured between the surface of the PV module and a horizontal ground surface (Figure 1). The PV module generates maximum output power when it fac
What is the maximum voltage a photovoltaic module can run?
For roof use, the maximum system voltage must not exceed 600V according to National Electrical Code. Under normal conditions, a photovoltaic module is likely to experience conditions that produce more current and/or voltage than reported at standard test conditions.
