Photovoltaic panel type II card installation

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.

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 to install a solar photovoltaic system?

The installer should conform to all the safety precautions listed in this guide when installing the module. Local codes should also be followed in such installations. Before installing a solar photovoltaic system, the installer should become familiar with the mechanical and electrical requirement for such a system.

Can multiple PV modules be connected in the same system?

Do not use modules of different configurations in the same system. Several modules are connected in series and then in parallel to form a PV array, especially for application with a high operation voltage. If modules are connected in series, the total voltage is equal to the sum of individual voltages.

Do JA Solar modules need a dc cathode?

For optimal performance, JA Solar Modules should only be used in configurations where the DC cathode of the Modules array is connected to ground. Failure to comply with this requirement will reduce the performance of the system and invalidate JA Solar’s Limited Power Warranty for Modules.

How do I mount a PV module to a substructure?

MOUNTING INSTRUCTIONS PV modules can be mounted to the substructure using either corrosion-proof M8 bolts placed through the mounting holes on the rear of the module or specially designed module clamps. A clearance of at least 115mm(4.5in) (recommended) is provided between modules frame and the surface of the wall or roof.
