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.

Can solar panels be wired in parallel?

You should know that there are limitations for series solar panel wiring. In the U.S., solar strings are required to feature a maximum voltage of 600V, so solar arrays comply with article 690 section 7 of the National Electrical Code (NEC 690.7). Wiring solar panels in parallel increases the output current, while keeping the voltage constant.

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.

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 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 create a solar panel wiring diagram?

There are several ways to create your own solar panel wiring diagram — you can draw it out on paper, print out an existing diagram and mock it up with a pen to fit your liking, or design it from scratch digitally.
