Photovoltaic panel puncture sheet installation diagram

Which direction should a photovoltaic module be installed?

When installing photovoltaic modules in the northern Hemisphere, the optimal installation direction of the module is to face south; When installing photovoltaic modules in the Southern Hemisphere, the optimal installation direction of the module is to face north. Serial connected PV modules should be installed in the same orientation and Angle.

How do I install a solar photovoltaic system?

Installing solar photovoltaic systems requires specialized skills and knowledge. Installation should only be performed by qualified personnel. Before installing a solar photovoltaic system, installers should familiarize themselves with its mechanical and electrical requirements.

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.

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 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.
