The photovoltaic Module produces electricity when exposed to the sunlight, even at low light levels or when
other sources illuminate the front face. The voltage of a single Module is less than 50 V DC. However, the
voltage increases as Modules are connected in series and the available current increases as the Modules are
connected in parallel. Thus, for a Module connected within a system, contact with electrically active parts of
the Module such as terminals can result in lethal shock, sparks and burns. The only way to eliminate this
hazard is to prevent exposure of the Module(s) to light.
To avoid the hazard of electric shock and injury when installing,
wiring, operating and maintaining the PV modules, below guidelines
shall be strictly followed.
•Cover the entire front surface of the PV Module with a dense, opaque material such as cardboard box,
during installation and handling of the Modules.
•Do not expose Back sheet directly to sunlight.
•Work only under dry conditions, with dry Modules and Insulated tools.
•Be sure to completely ground all Modules.
•Since sparks may occur, do not install the Module where flammable gases or vapors are present.
•Module installation and operation should be performed by qualified personnel only. Children and
unauthorized persons should not be allowed near the installation of PV Modules.
•Use Module for its intended function only.
•Be sure that all other system components are compatible, and they do not subject the Module to
mechanical or electrical hazards.
•Do not touch terminals while Module is exposed to light or during installation. As a precaution use
properly insulated tools only.
•Do not damage or scratch the back sheet of the Module.
•Do not use the junction box to hold or transport the Module.
•Do not drop Module or allow objects to fall on the Module.
•Do not stand or step on the Module.
•Do not disassemble, modify or adapt the Module or remove any part or labeling installed/ pasted by the
manufacturer.
•When carrying a Module, two or more people should carry it by its frame wearing non-slip gloves (to
avoid injury by a slipped Module, or by the edge of frame, and so on).
•Only PV Modules with the same cell type and size should be connected in series.
•Avoid uneven shade on the PV Module surface. Shaded cells may become hot (hot spot phenomenon)
which may result in permanent damage to the Modul
e
.
•Do not drill holes in the frame or glass of the Module, it may compromise the frame strength and cause
corrosion of the frame and also voids the warranty.
•Do not treat back sheet and front surface of the Module with paint and adhesives.
•Do not artificially concentrate light on the Module.
