Photovoltaic bracket disassembly diagram explanation

What is a photovoltaic mounting system?

Photovoltaic mounting systems (also called solar module racking) are used to fix solar panels on surfaces like roofs, building facades, or the ground. [ 1 ] These mounting systems generally enable retrofitting of solar panels on roofs or as part of the structure of the building (called BIPV). [ 2 ]

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.

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.

Should a fixed PV module be tilted at the same angle?

It is a common practice to tilt a fixed PV module (without solar tracker) at the same angle as the latitude of array's location to maximize the annual energy yield of module. For example, rooftop PV module at the tropics provides highest annual energy yield when inclination of panel surface is close to horizontal direction.

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 happens if you disconnect a photovoltaic module?

Contact with a DC voltage of 30V or more is potentially hazardous. When disconnecting wires connected to a photovoltaic module that is exposed to sunlight, an electric arc may result. Such arcs may cause burns, may start fires and may otherwise create problems. Therefore, be extremely careful!
