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.

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.

Can PV panels be attached to standing seam ribs?

Accordingly, in lieu of rails, it is recommended that external seam clamps be used to attach PV panels to standing seam ribs. The external seam clamps should be located so that they do not interfere with the thermal expansion and contraction between the metal panels and the concealed clips.

Can PV panels be attached to metal roof ribs?

PV panels may be attached to standing seam metal roof ribs with panel clamps attached to external seam clamps (Figure 12), or panels may be attached to rails that are attached to the ribs. Use of rails can result in overstressing the concealed clips that attach the metal 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.

How does a photovoltaic system work?

The heart of a photovoltaic system is the solar module. Many photovoltaic cells are wired together by the manufacturer to produce a solar module. When installed at a site, solar modules are wired together in series to form strings. Strings of modules are connected in parallel to form an array.
