6 FAQs about [Unpacking and mounting of 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.
Are photovoltaic modules dangerous?
Photovoltaic modules can produce DC electricity when exposed to light and therefore can produce an electrical shock or burn. DC voltage of 30 Volts or higher is potentially lethal. Modules produce voltage even when are not connected to an electrical circuit or load. Please use insulated tools and rubber gloves when working with modules in sunlight.
What happens if a PV module is exposed to sunlight?
PV module connectors pass direct current (DC) when exposed to sunlight or other light sources. Contact with electrically active parts of the module, such as terminals, can result in injury or death, irrespective of whether or not the module and the other electrical equipment have been connected.
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.
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!
