Double-glass photovoltaic panel installation array

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 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.

Can JA Solar modules be installed on a roof?

JA solar modules have been listed as Class A according to IEC 61730-2 standard. For roof installations, modules should be mounted over a fire resistant covering suitable for this application, with adequate ventilation between the modules backsheet and the mounting surface. Roof constructions and installations may affect the fire safety of building.

What is UL Standard 1703 for photovoltaic modules & panels?

An addendum to UL Standard 1703 “Flat Plate Photovoltaic Modules and Panels” recommends metal combinations not exceed an electrochemical potential difference of 0.6 Volts. The frame rails have pre-drilled holes marked with a grounding sign. These holes should be used for grounding purposes and must not be used for mounting the modules.

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 is the minimum wire size for a solar PV system?

JA Solar recommends installers use only sunlight resistant cables qualified for direct current (DC) wiring in PV systems. The minimum wire size should be 4mm2. Rating Required Minimum Field Wiring Cables should be fixed to the mounting structure in such a way that mechanical damage of the cable and/or the modules is avoided.
