Manual loading and unloading of photovoltaic brackets

What happens if solar photovoltaic module part by Shadow block?

If solar photovoltaic module part by shadow block, which can lead to reverse voltage related to solar cells, solar photovoltaic modules in other unaffected battery string or other solar PV modules in the system and current will force through keep out part of the power loss and heat affected cell.

Can a PV module be deformed during installation?

The aluminum frame of the PV module shall not be deformed during installation, and the front of the module shall not be covered. Each PV module needs to be fixed with at least four clamp, and the applied torque is 16N · m ~ 20N ·m.

How does a solar photovoltaic module bypass a diode?

When the solar photovoltaic module is connected in parallel with the bypass diode, the current in the system will flow directly through the diode, so as to bypass the blocked part of the solar photovoltaic module and minimize the heating degree and power consumption of the solar photovoltaic module. Each module has three diodes.

Which materials should be used to install photovoltaic modules?

JA Solar recommends that when installing modules at the seaside, stainless steel or aluminum materials should be used to contact the photovoltaic modules, and the installation parts should be well protected from corrosion. The tilt angle of the modules is measured between the surface of the modules and a horizontal ground surface.

What should I do if my PV module is broken?

Contact with module surfaces or frames may cause electric shock if the front glass is broken or the backsheet is torn. The PV module does not contain any serviceable parts. Do not attempt to repair any part of the module. Keep the junction box cover closed at all times. Do not disassemble a module or remove any module part.

How to maintain a photovoltaic system?

Warning: Any electrical maintenance must shut down the PV system firstly. Improper system maintenance may cause fatal dangers such as electric shock and burning. Dust accumulation on the glass surface of the module will reduce its power output and may cause hot spots. So the surface of photovoltaic modules should be kept clean.
