No Shading on module
• Utmost care to be taken while designing the modules' layout to avoid slightest of partial
shading on the module in any point of the day in the whole year cycle.
Lightning Arrestor
• Any installation should be supported by a properly designed appropriate Lightning
Protection System and Surge protection Device.
I. FIRE SAFETY
• The devices of on‐roof systems can affect the fire safety of the building, improper
installations can result in a hazard in case of fire.
• Roof mounted PV modules to be mounted over fire resistant roof.
• Improper installation may contribute to fire hazards. Additional devices such as
ground fault indicator, fuses etc., may be required.
• The PV module is declared as non‐explosion‐protected equipment and must not be
installed near open flames, flammable materials and vapors.
J. JUNCTION BOX
• HHV Solar modules of type HSTXY12xxxZ & HSTXY24xxxZ are factory‐fitted with
Tyco/ Cixi Renhe/ Huber & Suhner made junction boxes with approved UV
resistant cables of size 4.0 mm2 and terminated with the press‐fit type
connectors, fitted as per the instructions of Tyco/ Cixi Renhe/ H&S. Please do
not open the junction box as there are no user serviceable parts inside.

• The module wiring MUST NOT be opened under load. Any connection and
disconnection must be made only when the current is not flowing in the module.

Solar Module Installation Manual
• The cables are of equal lengths which are appropriate for series connection of the
modules. The cables are marked on them (+) and (‐) for easy identification of the
terminals.
K. BYPASS DIODES
The bypass diodes are factory fitted inside the junction box. Please do not remove these
bypass diodes. These diodes help in by‐passing the shaded strings of the cells and thereby
preventing the modules from heating.

L. SERIES FUSE
In order to protect the module from short circuits it is recommended to install a series fuse of
15 A. A maximum of two strings can be connected in parallel without using over‐current
protection device (fuses...) incorporated in series within each string. Three of more strings
can be connected in parallel if an appropriate and certified over‐current protection device is
installed in series with each string.
M. MODULE MOUNTING
HHV Solar modules can be mounted on the rails using 4 mounting holes which are located at
the back of the module frame. The mounting rails must be positioned perpendicular to the
length of the module. The rails must be strong enough to support the weight of the module
and forces generated by the high wind load. The modules have to be secured using the 4
mounting holes and 6 mm stainless steel bolts and nuts. Locking washers must be included
between the frame and the bolt as shown in the Figure1.
