mechanical and electrical requirement for such a system. Keep this guide in a safe place for future
reference (care and maintenance) and in case of sale or disposal of the module at the end of its
useful life.
General
• Installing solar photovoltatic systems may require specialized skills and knowledge. Installation
should be performed only by qualified persons.
• All modules come with a permanently attached junction box and #12 AWG teminated in
Muti-contact (MC4) PV-KBT4 (female) or PV-KST4 (male) connectors.
• The installer should assume the risk of all injury that might occur during installation, including,
without limitation, the risk of electric shock.
The solar photovoltatic electrical energy production system must comply with the following
• table for suggested current and vol tage specifications:
• One individual module may generate DC voltages greater than 30 volts when exposed to direct sunlight.
Contact with a DC voltage of 30V or more is potentially hazardous. Electrical joints such as the wire termi-
nal will cause sparks, burning or deadly electric shock. Please do not touch such terminals directly under
any circumstances.

14
ELECTRICAL WORK
• When disconnecting wires from a photovoltaic module that is exposed to sunlight, an electric arc may re-
sult. Such arcs may cause burns, combustion and may otherwise create problems. Therefore, be extremely
careful!
• Photovoltaic solar modules convert light energy to direct-current electrical energy. They are designed for
outdoor use. Modules may be ground mounted , mounted on rooftops, vehicles, or boats. Proper design of
support structures is the responsibility of the system designer and installer. Proper use of mounting holes
is suggested in a following paragraph.
• Do not attempt to diassemble the module, and do not remove any attached nameplates or components.
• Do not apply paint or adhesive to module top surface.
• Do not use mirrors or other magnifiers to artificially concentrate sunlight on the module.
• When installing the system, abide with all local, regional and national statutory regulations.
• Obtain a building permit where necessary. Abide with any local and national regulations when mounting
on vehicles or boats.
Safety precaution for installing a solar photovoltaic system
• When installing the solar modules or repairing the air conditioner, ensure the circuit breaker between
the solar panel and the outdoor unit is in the “OFF” state(push the switch to “OFF” position). During
normal operation , the circuit breaker should be in the “ON” state(push the switch to “ON” position)

15
Ecosolaris Solar Heat Pump Installation Manual
ELECTRICAL WORK
• Solar modules produce electrical energy when light strikes on their front surface. The DC voltage will
exceed 30V. If modules are connected in series, the total voltage is equal to the sum of the individual
module voltages. If modules are connected in parallel, the total current is equal to the sum of individual
module currents.
Connect the panels in Series
• Keep children well away from the system while transporting and installing mechanical and
electrical components.
• Completely cover the module with an opaque material during installation to keep electricity from being
generated. Do not touch the components or the end of live wires. However, if appropriate protections
has been taken during the operation according to the local safety regulations, the above requirement is
unnecessary.
• Do not wear metallic rings, watchbands, ear, nose, lip rings or other metallic devices while installing or
troubleshooting photovoltaic systems.
• Use only insulated tools that are approved for working on electrical installations

16
ELECTRICAL WORK
• When performing installation in dry conditions, please ensure the tools used in the dry.
• Abide with the safety regulations for all other components used in the system, including wiring and ca-
bles, connectors, charging regulators, inverters, storage batteries and rechargeable batteries, etc.
• Use only equipment, connectors, wiring and support frames suitable for use in a solar electric systems.
Always use the same type of module within a particular photovoltaic system.
• The module frame must be properly grounded. The grounding wire must be properly fastened to the
module frame to assure good electrical contact. Use the recommended type, or an equivalent, connec-
tor for this wire.
• Under mormal outdoor conditions the module will produce current and voltages that are different than
those listed in the date sheet. Data sheet values are values expected at standard test conditions. Accord-
ingly, during system design, values of short-circuit current (Isc) and open-circuit voltage (Voc) marked
on UL series modules should be multiplied by a factor of 1.25 when determining component voltage
ratings, conductor ampacity, fuse size and size of controls connected to the module or system output.
• The hole in the back of the module frame is used to drain the water, ensure not to be blocked.
Mechanical installation
1. Selecting installation place
• Select a suitable place for installation of the module.The module should not be shaded at any time of
the day.
• The module should be facing due south in northern latitudes and due north in southern latitudes for
best power production.
• For detailed information on the best elevation tilt angle for the installation, please consult with the solar
photovoltatic system supplier.
• Do not use module near the place where the flammable gas may be generated or collected

2. Selecting the proper support frame
• Always observe the instructions and safety precautions included with the support frame to be used with
the module.
• Never attempt to drill holes in the glass surface of the module, it will void the warranty.
• Do not drill additional mounting holes in the frame of the module, it will void the warranty.
• Modules must be securely attached to the mounting structure using four mounting points for normal
installation. If additional wind or snowloads are considerated for the installation, additional mounting
points are also used.
• The support frame must be made of durable, corrosion-resistant and UV-resistant material.
• The heat expansion and cold contraction of the support frame should have no affection to its usage and
performance.
3. Ground mount
• Select the height of the mounting system to prevent the lowest edge of the module from being cov-
ered by snow for a long time in winter in areas that experience heavy snowfalls. In addition, assure
the lowest portion of the module is placed high enough so that it is not shaded by plants or trees or
damaged by sand and stone driven by wind.

18
ELECTRICAL WORK
4. Roof mount
• When installing a module on a roof or building, ensure that it is securely fastened and cannot fall as a
result of wind or snow loads.
• Provide adequate ventilation under a module for cooling (5cm minimum air space between module
and mounting surface).
• When installing module on a roof, ensure that the roof construction is suitable. In addition, any roof pen-
etration required to mount the module must properly sealed to prevent leaks.
In some cases, a special support frame may be necessary.
• The roof installation of solar modules may affect the fireproofing of the house construction, so it is
necessary to use an earth ground fault circuit breaker. Any unproper installation may cause accidental
injuries.
• When installing the module on a roof or building, do so in calm winds. Installing a module during strong
winds may cause accidents.
5. Pole mount
• When installing a module on a pole, choose a pole and module mounting structure that will withstand
anticipated winds for the area. The pole must have a solid foundation.
