1. OBJECTIVE
The purpose of this procedure is to provide installation instructions for EST SERIES thin film solar
module for field installation.
2. SCOPE
This procedure establishes the key installation requirements to mount EST SERIES thin film solar
modules in the field which includes, but is not excluded to, roof tops, solar farms, and commercial
buildings.
3. RESPONSIBILITY
ENN Solar Energy Co. Ltd. shall maintain the engineering change control of this product.
End installer of the thin film Photovoltaic (PV) modules is responsible for the design and
integrity of the mounting structure of the modules. The PV module manufacturer is responsible
for the design and structural integrity of the PV modules. Installation of the PV modules must be
performed by appropriately trained and equipped installers.
Supplier is responsible for maintaining and supporting the bill of materials on the Supplier database.
4. INSTALLATION
4.1. Unpacking and handling
The site and personnel must obtain the proper handling and transp o rt equipment to install the PV
modules.
4.2. Personnel
Only trained personnel are to handle, transport, and install the PV modules. Immediate exposures
to sunlight instantly energ iz e the modules and pose a shock risk.
4.3. Safety
It is the responsibility of the supplier to provide adequate safety to its employees while
performing the procedures.
Under normal conditions, a photovoltaic module may experience conditions that produce more
current and/or voltage than reported at Standard Test Cond itions. According ly, the values of Isc
and Voc marked this module should be multiplied by the following factors: The multiplying
factors at conditions of an irradiance of 125 mW/cm^2, AM 1.5 spectrum is 1.19, and at a cell
temperature of minus 10 deg C for Voc is 0. 89 5 and at plus 75 deg C for Isc is 1.05.

4.5. Installing the modules
4.5.1. Materials of the mounting st ructure must be compatible with t he PV mo dule rails as to
not allow galvanic corrosion to either member (PV rail or mounting structure). The PV
rails are made of galvanized steel.
4.5.2. PV modules are not to be installed around or near open flames, flammable gases or
vapors, constant wetting/moisture (fountains), salt air conditions, or other corrosive
chemicals/vapors.
4.5.3. Orientation and tilt of the modules are responsibilities of the end installer.
4.5.4. Sunlight exposure is the responsibility of the end installer. Care s h ould be taken to place
the modules in areas without overshadowing or significant shade.
4.5.5 For roof mounting, the module must be m ounte d over a fire resistant roof covering rated
for the application.
4.5.6 The modules should be mounted with the junction box connectors facing down to
minimize the ingress of water.

4.7. Wiring
4.7.1. Warnings
4.7.1.1. If, during self assembly, parts and tools other than those stated by MC are used
or if the preparation and assembl y instructions described here are disregarded
then neither safety nor compliance with the technical data can be guaranteed
4.7.1.2. For protection against electric shock, PV connectors must be isolated from the
power supply while being assemble d or disassembled.
4.7.1.3. The end product must provide protection from electric shock.
4.7.1.4. The integral output connector should only be used where they will not interrupt
current. Unplugging under l oa d : PV plug connections must not be unpl u gged
while under load. They can be placed in a no load state by switching off the
DC/AC converter or breaking the A C ci rcuit interrupter. Plugging and
unplugging while under voltage is permitted.
4.7.1.5. It is unadvisable to use non-tinned cables of type H07RN-F, since with oxidized
copper wires the contact resistances of the crimp conn ection may exceed the
permitted limits.
4.7.1.6. Disconnected connectors should be protected from dirt and water with sealing
caps.
4.7.1.7. Plugged parts are watertight IP67. They can not be used permanently under
water. Do not lay PV connectors on the roof surface.

To wire modules in series use an interconnect cable assemblies that has a female
connector on one end and a male connector on the other. The modules can be
connected together in a chain forming a series connected circuit. (See Figure 7).
The maximum current of fuse for the connected circuit can be found in the
section 7.
Figure 7 – Series connection
4.7.6.2. Parallel
To wire the modules in parallel it is necessary to connect the module leads using
a method that meets national and local electrical codes and to us UL listed
hardware

4.7.7. Grounding
Attach a ground conductor to two grounding bushing lug mounted at the designated location
shown in Figure 8 (An Ilsco GBL-4DB is shown in the Figure). Use an Ilsco GBL-4DB
(Tin Plated) , and M5 stainless steel hardware (screw, lock washer, star washer, flat washer
and nut) as shown in Figure 9. The assembly must be torque to 6.1 Nm . The copper
conductor must be attached to the ground lug using the stainless steel set screw provided by
the lug manufacturer. The electrical wiring of the ground circuit should be such that the
negative leg of the array circuit shall have the same voltage as earth ground, and when
performing a DC voltage measurement between the positive leg of array circuit and earth
ground the meter shall read a positive DC voltage, or when performing a DC voltage
measurement between t he negative leg of array circuit and earth ground the meter shall read
zero volts DC voltage. Please refer to NEC Article 690 on grounding PV arrays for specific
requirements.
