Manual digging holes for photovoltaic panels

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.

What is included in a solar installation manual?

This installation manual contains important electrical and mechanical installation information as well as safety information that you must be familiar with, providing important safety instructions for the installation, use and maintenance of solar modules.

What is a typical grounding hole?

The grounding hole on the frame is marked with typical grounding symbol ( ) according to IEC 61730-1 standard, which can only be used for grounding, not for module installation. Grounding between modules shall be confirmed by qualified electricians and grounding devices shall be manufactured by qualified electric manufacturer.

How does a photovoltaic module work?

The photovoltaic module tracks the mounting mode of the bracket, and the maximum variable allowed at the edge of the module ΔL=25mm. After evaluation, the appearance caused by self-weight or other loads is not identified as a defect and is not covered by the warranty.

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.
