How to tighten the middle pressure block of photovoltaic panels

What is a mid clamp on a solar panel?

Mid clamps are installed between 2 solar panels, clamping down both solar panels at once while securing them onto the Solar Profile. A mid clamp requires 1 bolt and 1 t-nut to tighten and secure solar panels onto Solar Profiles.

How do I install a second PV module?

Place second PV module into rail, leaving a 20mm gap between modules and insert the mid clamps, slide the PV module flush against mid clamp closely, then tighten the mid clamp screw to 10 N·m using 6 mm Allen key or hex driver bit. Repeat procedure for follow mid clamps. Ensure the PV modules are neatly square to one another

How do I install a double glass PV module?

Insert the PV module into the clamp, and make sure the module edge touch to the EPDM closely and then tighten the nut with uniform torque values using a qualified torque wrench to ensure the double glass module is firmly secured. Trina suggests using M8 bolts to affix the double glass modules onto the clamp.

Where should clamps be connected to the PV module?

When the mechanical load pressure is ±2400Pa, Clamps should be connected to the module between 400 and 500mm from the edge of the module. This distance is from the module edge to the middle of the clamp. *NOTE: We need two or three support rails below the PV module to make sure the module have a good mechanical load performance.

Why are solar panel mounting clamps important?

Picking a high quality clamps are pivotal to the survival of your solar panels, because a loose clamps can release any pressure that secures your solar panels and most likely would cause your solar panels to fall and damaged. What Are The Types of Solar Panel Mounting Clamps?

How do you protect a PV module from soiling?

Protect plug contacts against soiling and do not make any plug connections using soiled plug contacts. Do not install or handle modules when they are wet or during periods of high wind. Do not connect cable from the positive terminal to the positive terminal of one single PV module. Make sure connectors have no gap between insulators.
