What are mounting brackets & rails for solar panels?

Mounting Brackets are the primary components that attach the solar panels to the mounting surface. They come in various types depending on the mounting surface (roof, ground, pole, etc.). Rails: Rails are long, horizontal structures attached to the solar panels using clamps. They provide a stable base for the solar panels.

Which Racking clamps should I use for Trina Solar racking?

For C structure steel type 1 racking, due to the amount of space inside the racking section, many choices are available including T-shape nuts. Please consult with a Trina Solar engineer before installing with the frameless clamps. Clamps should be connected to the module between 300 and 400 mm from the edge of the module.

What size bolt & nut do I need for a clamp?

Please note that all dimensions below are in mm units. 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. Trina suggests using M8 bolts to fix the clamp. The torque for M8 screw is 16-20 N*M.

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.
