4 |ENVIRONMENTAL CONDITIONS INFORMATION
4.1. ENVIRONMENTAL CONDITIONS
Only Install the PV modules within the following conditions:
1. Ambient temperature: -40°C to 40°C
2. Operating temperature: -40°C to 85°C
3. Storage temperature: -30°C to 50°C
4. Humidity: <85RH%
5. Keep modules away from inflammable gas, hazardous chemicals, or re sources.
4.2. SITE INSTALLATION
1. To ensure the modules receive the most sunlight exposure, position the modules in a manner to minimize
the chances of shading throughout the day by trees, buildings, or any other surrendering objects.
2. Solar modules should normally be mounted facing the equator at an angle to the horizontal plane equivalent
to the latitude of the installation for optimum energy generation. The module tilt angle is measured between
the solar modules and the horizontal (Figure 1). Any slope less than 5in/ft(127mm/305mm) is required
to maintain a re class rating. The PV module generates maximum output power when it faces the sun directly.
3. Do not install modules in the location where they will be immersed in water or continually exposed to water
from a sprinkler, hose, or fountain.
4. Please leave a safe working area between the edge of the roof and the external edge of the solar array when
installing modules on a roof.
5. Avoid a mounting method that will block the drainage holes in the module frame.

5 |MOUNTING OVERVIEW
Figure 2: PV Module I Mechanical Drawing
When the climate of the project site is normal,
we recommend using 4-hole mounting (M8 nut).
The yellow 4-hole mounting (M8 nut), or blue
4-hole mounting (M8 nut) can be used.
When the climate of the project site reaches
severe conditions (2400Pa wind load and 5400Pa
snow load), the blue or yellow 4-hole mounting
(M8 nut) needs to be used, in addition to the
middle red auxiliary mounting hole (M6 nut).
5.1 MOUNTING
Solar PV modules usually can usually be mounted by using
the following methods: bolts or clamps.
PV modules can be mounted to a substructure with either
corrosion-proof M8 (bolts placed through the mounting
holes on the module frame) or with specially designed
module clamps.
Note: All installation methods herein are only for
reference. Boviet Solar will not provide related BOS
components. The system installer or trained professional
personnel must be responsible for the PV system’s design,
installation, mechanical load calculation and security
of the system.
Regardless of the method, the nal installation of the
modules should ensure that:
A clearance of at least 115mm (4.5in) is required provided
between the module frame and the surface of the wall
or roof. The minimum distance between two modules is
10mm(0.4in).
The mounting method should not block the drainage holes.
Panels are not subjected to wind or snow loads exceeding
the maximum permissible loads and are not subject
to excessive forces due to the thermal expansion
of the support structures.
Note: The drainage holes cannot be blocked in any
situation during installation or use.

Figure 4: PV Module I Mounting Information, Installed with screw fitting method
When the climate of the project site is normal, we recommend using 4-hole mounting (M8 nut). The yellow 4-hole
mounting (M8 nut), or blue 4-hole mounting (M8 nut) can be used.
When the climate of the project site reaches severe conditions (2400Pa wind load and 5400Pa snow load), the blue or
yellow 4-hole mounting (M8 nut) need to be used, in addition to the middle red auxiliary mounting hole (M6 nut).
In any case clamps should not contact the glass or deform the assembly frame.
The surface of the clamps touching the frame should be flat and smooth; otherwise, the frame and components may be
damaged. For better performance be sure to avoid shading from module clamps.
The drainage holes are not blocked by clamps.
The module frame is not modied under any circumstances as this will not void the warranty.
5.2 MOUNTING WITH BOLTS
There are four 4 (9*14mm) and six (7*10mm size) mounting holes at each panel to mount the modules on a supporting
structure. The module frame must be installed on the mounting rail using M8 corrosion-proof screws together with
spring washers and flat washers in four (4) symmetrical locations on the module.
The applied torque should be approximately 17-23 N*m. The applied torque value should be big enough to x the
modules securely. For special support systems or special installation requirements, please conrm torque value with the
specic support supplier. Please nd detailed mounting information in Figure 4.
When using six (6) mounting holes, the middle two (2) mounting holes are the auxiliary mounting holes which use M6
bolts. The applied torque should be approximately 7-11 N*m for these bolts. PV module mounting information when
installed with screw tting method as shown in Figure 4.
07

5.3 MOUNTING WITH CLAMPS
Mounting with clamps at the long side of frames
The module frame is not to be modied under any circumstance. When choosing this type of clamp mounting method,
please be sure to use at least four (4) clamps on each module, two (2) clamps should be attached on the long sides
of the module.
Depending on the local wind and snow loads, if excessive pressure load is expected, additional clamps may be required
to ensure that the module can bear the loads. The applied torque should be 18-24 N*m.

Mounting with clamps at short side of frames
Given that some projects need to install the clamps on the short side of the frame, please nd detailed mounting
information as shown in Figure 7. The mounting placement distance should be further than J, but less than
K as shown below.
Boviet Solar suggests that the clamp width should not be less than 35mm, the thickness should not be less than 3mm,
and that the screw should be an M8 model. It is recommended that the tightening torque of the clamp screw nut be
within 18-24 N*m.

5.2 GROUNDING
1. All module frames and mounting racks must be properly grounded in accordance with the National Electrical Code
and any local jurisdictions.
2. The modules are required to be grounded, and the module installation needs to comply with all local electrical codes
and regulations. Additionally, the grounding connection should be made by a qualied electrician.
3. Proper grounding is achieved by bounding the module frame and all metallic structural components together using
a suitable grounding conductor. The grounding conductor or strap may be copper, copper alloy, or another material
acceptable for use as an electrical conductor per respective National Electrical Codes. The grounding conductor
must make a connection to earth using a suitable earth ground electrode.
4. Where common grounding hardware (nuts, bolts, star washers, split-ring lock washers, flat washers, etc.) is used
to attach a grounding/bonding system, the attachment must be made in conformance with the manufacturer’s
instructions of grounding devices used in the system.
5. Common hardware items such as nuts, bolts, star washers, lock washers and the like have not been evaluated
for electrical conductivity or for use as grounding devices and should be used only for maintaining mechanical
connections and holding electrical grounding devices in the proper position for electrical conductivity. Such devices,
when supplied with the module and evaluated through the requirements in IEC and UL standard, may be used for
grounding connections in accordance with the instructions provided with the module.
6. Boviet Solar recommends the method below:
a. A grounding kit with M4 size SS cap bolt, M4 size SS flat washer, M4 size SS cup washer, and M4 size
SS nut (with teeth) is to be attach a copper grounding wire to a grounding hole pre-drilled on the frame.
b. Attach the wire between the flat washer and the cup washer. Ensure the cup washer is between the frame
and the wire with concave side up to prevent corrosion due to dissimilar metal. Tighten the bolt securely
using the SS nut with teeth (a wrench may be used in this application.) The tighten torque should be 2-3N*m.
7. Alternate grounding options built into the racking system are acceptable as long as they have been UL approved.

06 |ELECTRICAL CONFIGURATION
PV systems operates automatically and require day-to-day supervision. The solar array generates DC electricity
whenever light falls on it. Similarly, the inverter automatically turns ON as soon as there is sufcient solar energy
from the array to efciently convert it into grid quality AC Power.
Boviet Solar produces following models, XXX presents the power range.

Table 5: Electrical Data
The electrical characteristics are within ±10 percent of the indicated values of Isc, Voc and Pmax under Standard Test
Conditions (STC) (irradiance of 100mW/cm², AM 1.5 spectrum, and a cell temperature of 25°C (77°F)).
Under normal conditions, a photovoltaic module is likely to experience conditions that produce more current and/or
voltage than reported at standard test conditions. The requirements of the National Electrical Code (NEC) in Article 690
shall be followed to address these increased outputs. In installations not under the requirements of the NEC, the values
of Isc and Voc marked on this module should be multiplied by a factor of 1.25 when determining component voltage
ratings, conductor ampacities, overcurrent device ratings, and size of controls connected to the PV output.

07 |WIRING AND NOTES
All wiring should be performed by qualied installers according to the local codes and regulations.
1. Before connecting modules, always ensure that the contacts are corrosion free, clean, and dry.
2. Before connecting modules, verify that the proper electrical values are measured.
3. To minimize the risk of indirect lighting strike and avoid forming closed loops, review that wiring has been properly
done before starting. If the measured data of open circuit voltage and short-circuit current differ from the
specications, please check the wiring before proceeding.
4. Products can be irreparably damaged if an array string is connected in reverse polarity to another. Always verify the
voltage and polarity of each individual string before making a parallel connection. If strings are connected in reverse
polarity and a difference of more than 2V between 10 strings are measured, please check the string wiring
before making the parallel connection.

08 |MAINTENANCE INFORMATION
A well-designed system needs minimal maintenance.
Maintenance should be carried out at least once a year by well-trained personnel.
Check that the mounting hardware is properly tightened. Check if cables, nuts, and bolts are secure and not loose.
Tighten any loose components if necessary.
Check ground resistance performance and water resistance of connecting cables, grounding cables, connectors, and
any other connections.
Verify that the electrical and mechanical connections are free from corrosion.
Do not touch the live part of the wire, cable, or connector directly, but only with safety equipment (insulating tools and
electrical protection) when necessary.
Use an opaque cloth or other opaque materials to cover the front side of the modules during the maintenance. When
exposed to sunlight the module may produce high voltage which can cause injury and even death.
In the event that modules need to be cleaned, clean modules with a soft cloth together with a mild detergent and clean
water. To avoid severe thermal shocks, which might damage the module, use water at a similar temperature to the
modules being cleaned.
09 |WARNING INFORMATION
Contact your installer immediately if you suspect your system is not working properly. For any warranty related concerns
contact our Boviet Solar after sales service team at bovietsolar.com/company/contact-us or your sales contact.
WARNING: The PV system must be shut down rst if it needs any electrical maintenance. Improper maintenance may
cause burns and/or electrical shock, which can both be lethal.
