How do I mount a PV module to a substructure?

MOUNTING INSTRUCTIONS PV modules can be mounted to the substructure using either corrosion-proof M8 bolts placed through the mounting holes on the rear of the module or specially designed module clamps. A clearance of at least 115mm (recommended) is provided between modules frame and the surface of the wall or roof.

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.

What is the total voltage of a photovoltaic module?

If modules are connected in series, the total voltage is equal to the sum of individual voltages. For applications requiring high currents, several photovoltaic modules can be connected in parallel; the total current is equal to the sum of individual currents.

Can multiple PV modules be connected in the same system?

Do not use modules of different configurations in the same system. Several modules are connected in series and then in parallel to form a PV array, especially for application with a high operation voltage. If modules are connected in series, the total voltage is equal to the sum of individual voltages.

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.

Do PV modules need to be grounded?

The frame of the PV module, as well as any exposed non-current carrying metal parts of fixed equipment that can be energized must be grounded to avoid electrical shock. Renogy recommends grounding all PV module frames to ensure the voltage between the conductive equipment and the earth ground is zero in all circumstances.
