1 General requirements
Thank you for choosing SoliTek panels!
Please read this guide in it’s entirely before the installation.
The purpose of this document is to provide minimum requirements and recommendations for safe
and successful installation of SoliTek PV modules.
This document also contains requirements necessary to retain SoliTek PV module compliance with
IEC 61215 and IEC 61730 standards.
This guide contains basic information regarding JSC “SoliTek Cells” SOLID series photovoltaic
modules, their installation and safe handling. All instructions should be read and understood before
attempting installation. If there are any questions, please contact your dealer or JSC “SoliTek Cells”
for further information.
This documentation refers to the PV-modules themselves and is not meant to be a complete
installation manual for personnel not specifically trained to PV-modules. It serves as a general but
strictly mandatory to the Installer reference. Infringement or inaccurate observance of any clause of
this documentation voids the warranty.
The installer must understand and follow all applicable local, state, and federal regulations and
standards for building construction, electrical design, fire, and safety, and must check with local
authorities to determine applicable permitting requirements before attempting to install or maintain
PV modules and should become familiar with the mechanical and electrical requirements for
photovoltaic systems.
Failure of follow instructions in this guide may damage system components, endanger personnel,
damage property, or invalidate the panel warranty.
5
Rooftop PV systems should only be installed on dwellings that have been formally analyzed for
structural integrity, and confirmed to be capable of handling the additional weighted load of PV
system components, including PV modules, by a certified building specialist or engineer.
For your safety, do not attempt to work on a rooftop until safety precautions have been identified
and taken, including without limitation fall protection measures, ladders or stairways, and personal
protective equipment (PPE).
For your safety, do not install or handle PV modules under adverse conditions, including without
limitation strong or gusty winds, and wet or frosted roof surfaces.
The flat-plate PV module construction consists of a laminated assembly of solar cells encapsulated
within an insulating material within two glass sheets.
Keep this documentation in a safe place for future reference.
Do not attempt to disassemble the module, and do not remove any attached nameplates or
components! Doing so will void the warranty.
2 Handling
SoliTek PV modules must be transported in the supplied packaging only and kept in the packaging
until they are ready to be installed. Protect pallets against movement and exposure to damage during
transportation. Secure pallets from falling over. Do not exceed the maximum height of pallets to be
stacked, as indicated on the pallet packaging. Store pallets in a cool and dry location until the PV
modules are ready to be unpackaged.
SoliTek PV modules are heavy and should be handled with care. Never use the junction box or cables
as a grip. Do not exert mechanical stress on the cables. Never step on PV modules or drop or place
heavy objects on them. Be careful when placing PV modules on hard surfaces and secure them from
falling. Broken glass can result in personal injury. PV modules with broken glass cannot be repaired
and must not be used. Broken or damaged PV modules must be handled carefully and disposed of
properly.

3 Application
3.1 Restrictions
SoliTek PV modules must be mounted on appropriate mounting structures positioned on suitable
buildings, the ground, or other structures suitable for PV modules (e.g. carports, building facades or
PV trackers). PV modules must not be mounted on moving vehicles of any kind. Modules must not
be installed in locations where they could be submerged in water.
Artificially concentrated light must not be directed on SoliTek PV modules.
3.2 Recommendations
SoliTek recommends that PV modules be mounted at a minimum tilt angle of 10 degrees to allow for
proper self-cleaning from rain.
Partial or complete shading of a PV module or modules can significantly reduce system performance.
SoliTek recommends minimizing the amount of shade throughout the year to increase the amount
of energy produced by the PV modules.
High system voltages could be induced in the event of an indirect lightning strike, which could cause
damage to PV system components. The open area of wire loops should be minimized; in order to
reduce the risk of lightning induced voltage surges.
Better module ventilation and shorter connection cables increase electrical energy production.
For bifacial modules:
It is recommended to increase PV panel height from the ground so that more light can travel beneath
the module and then reflect
The bifacial gain increases significantly if modules are installed above white (high albedo value), light
reflecting surfaces.

4 Electrical installation
4.1 Safety
PV modules can produce current and voltage when exposed to light of any intensity. Electrical current
increases with higher light intensity. DC voltage of 50 Volts or higher is potentially lethal. Contacting
the live circuitry of a PV system operating under light can result in lethal electric shock.
De-energize PV modules by removing them entirely from light or by covering their front surface with
an opaque material. Regard the safety regulations for live electrical equipment when working with
modules that are exposed to any light. Use insulated tools and do not wear metallic jewelry while
working with PV modules.
In order to avoid arcing and electrical shock, do not disconnect electrical connections under load.
Faulty connections can also result in arcing and electrical shock. Keep connectors dry and clean, and
ensure that they are in proper working condition. Never insert metallic objects into the connectors,
or modify them in any way in order to secure an electrical connection.
Do not touch or handle PV modules with broken glass unless the PV modules are first disconnected
and you are wearing proper PPE. Avoid handling PV modules when they are wet unless cleaning the
PV modules as directed in this manual. Never touch electrical connections that are wet without
protecting yourself with insulated gloves.
The modules are qualified for application class A: Hazardous voltage (IEC 61730: higher than 50V DC;
EN 61730: higher than 120V), hazardous power applications (higher than 240W) where general
contact access is anticipated.
Installing solar photovoltaic systems requires specialized skills and knowledge. It should be
performed only by qualified and specially instructed personnel. The installer assumes all risk of injury,
including risk of electric shock.
Use only equipment, connectors, wiring and mounting hardware specifically designed for use in a
photovoltaic system.
8
Before any manipulation at an installed PV plant, switch it of first on AC-side after on DC-side of the
inverter or the charge controller.
When disconnecting wires connected to a photovoltaic module that is exposed to light, an electric
arc may occur. Arcs can cause burns, start fires or otherwise create safety (up to lethal electric shock)
problems.
Check for remaining voltage before starting and observe the local safety relevant regulations for such
working conditions.
Under normal conditions, a photovoltaic module can produce more current and/or voltage (here:
30V DC) than reported at standard test conditions.
Contact with a DC voltage of 30 V or more is potentially hazardous. Exercise caution when wiring or
handling modules exposed to sunlight.
Only connect modules with the same rated output current in series. If modules are connected in
series, the total voltage is equal to the sum of the individual module voltages.
Only connect modules or series combinations of modules with the same voltage in parallel. If
modules are connected in parallel, the total current is equal to the sum of individual module or series
combination currents.
Always use the same type of module within a particular photovoltaic system.
If the sum of short circuit currents of the parallel connected modules passes over the reverse current
string diodes or fuses have to be used in each string of modules connected in parallel. These string
diodes or fuses have to be qualified for the maximum expected current and voltage. The fuse rating
value is also corresponding to the maximum reverse current that a module can withstand. The
reverse current value can be found on the product label, in the product datasheet or chapter 9 of
installation manual. Observe the instructions and safety precautions for all other components used
in the system, including wiring and cables, connectors, DC-breakers, inverters, etc.
9
Use appropriate safety equipment (insulated tools, dielectric gloves and shoes, etc) approved for use
on electrical installations.
4.2 Configuration
Under normal conditions, a photovoltaic module is likely to experience conditions that produce more
current and/or voltage than reported at Standard Test Conditions (STC: 1000 W/m2, AM 1.5, and 25°C
cell temperature) or Bifacial Standard Test Conditions (BSTC: 1167 W/m2, AM 1.5, and 25°C cell
temperature). The short-circuit current (ISC) should be multiplied by a factor of 1.25 and the open-
circuit voltage (VOC) should be multiplied by a factor of up to 1.25 based on the lowest and highest
ambient temperature recorded for the installation location when determining component voltage
ratings, conductor current ratings, fuse sizes, and size of controls connected to the PV output.
Voltages are additive when PV modules are connected directly in series, and module currents are
additive when PV modules are connected directly in parallel. PV modules with different electrical
characteristics must not be connected directly in series. The use of suitable third-party electronic
devices connected to PV modules may enable different electrical connections and must be installed
according to the manufacturer’s specified instructions.
The maximum voltage of serial interconnection of the modules must be less than the maximum
certified module‘s system voltage. Also, the maximum input voltage of the inverter and of the other
electrical devices in the system must be taken into account. The open circuit voltage of the array
string needs to be calculated at the lowest expected ambient temperature for the location. The
maximal system voltage for module is indicated in the modules datasheet.
Accordingly for Pro or Bifacial series modules, the values of ISC and VOC under STC or BSTC marked
on this module should be multiplied by a factor of 1,25 when determining component voltage ratings,
conductor current ratings, fuse sizes, and size of controls connected to the PV output. In the USA,
refer to Section 690-8 of the National Electrical Code (NEC) for an additional multiplying factor of 125
percent (80 percent de-rating) which may be applicable.

4.3 Overcurrent protection device (OCPD)
When the potential reverse current of a PV string exceeds the rated SoliTek PV module series fuse
rating (values indicated at the module datasheet) an overcurrent protection device (OCPD) must be
used (IEC 61730-1 clause 12.3). An overcurrent protection device is required for each series string if
more than two series are connected in parallel. In this case, it is needed to use one fuse per string
rated at 1.25 x Isc or higher (Isc is the PV module’s short circuit current at STC). A PV fuse on each PV
string will protect the PV modules and conductors from overcurrent faults and help minimize any
safety hazards. The PV fuse will also isolate the faulted PV string so the balance of the PV system can
continue to generate electricity.
Fuse amp rating ≥ 1.25 x Isc
Select next higher standard rating at the catalogue of available PV Fuses.
Isc = Short-circuit current of one module at Standard Test Conditions (STC);
Considering the values of Isc of SoliTek modules, the right value of the PV Fuses to be used at the
installation is 20 A. SoliTek recommends using PV fuses in both the positive and negative conductors.
4.4 Cable & wiring
SoliTek PV modules are provided with two standard, sunlight resistant output cables that are
terminated with PV connectors ready for most installations. The positive (+) terminal has a male
connector while the negative (-) terminal has a female connector. The module wiring is intended for
series connections [i.e. male (+) to female (-) interconnections], but can also be used to connect
suitable third-party electrical devices that may have alternative wiring configurations so long as the
manufacturer’s instructions are followed.
Use field wiring with suitable cross-sectional areas that are approved for use at the maximum short-
circuit current of the PV module. All wiring must be double insulated, cross-linked cables with a
minimum rating of 1,8 kV (over 1500 V voltage) and minimum rated temperature of 90 ˚C. Wire size
