Installation manual for crystalline
solar photovoltaic modules（Half Cell）
hardware (bolt/flat washer/split washer/nut) should be stainless steel M8 size.
The minimum recommended length for each clamp is 50mm.
The modules have been designed to resist a static load of 2400Pa , and the resistance value can decrease if modules
are not mounted following the instruction above.
This manual is just for reference. Customer can select the corresponding installation manual based on the purchased
module.
4 ELECTRICAL INSTALLATION
4.1 MODULE SELECTION
Only connect modules of the same type, same configurations and same power class in the same system. This is the only way
to achieve optimal yields.
4.2 SAFTY FACTOR
Under normal conditions, a photovoltaic module may experience conditions that produce more current and/or voltage than
reported at Standard Test Conditions. Accordingly, the values of ISC and VOC marked on modules should be multiplied by a
factor of 1.25 when determining component voltage ratings, conductor capacities, fuse sizes and size of controls connected
to the module output.
Alternatively, all valid national regulations for the installation of electrical systems are to be applied.
Installer need to pay more attention to avoid the PID phenomenon, when installing the electrical system.
4.3 GENERAL INSTALLATION
Before installing modules, contact the appropriate authorities to determine permissions, installation and inspection
requirements to follow that apply to your site and installation.
Check applicable building codes to ensure that the construction or structure (roof, facade, support, etc.) where the
modules are being installed is strong enough to support the weight of the modules and all other system components.
If modules are connected in series, the total voltage is equal to the sum of individual voltages. The recommended max.
number of module (N) = Vmax system / [Voc(at STC)×1.25×1.25].
If the modules are allowed to be installed in parallel electrically, each module (or series string of modules so
connected) shall be provided with the maximum series fuse as specified. For applications requiring high currents,
several photovoltaic modules can be connected in parallel; the total current is equal to the sum of individual currents,
each module (or series string of modules so connected) shall be provided with the maximum series fuse as specified.
The recommended number of module in parallel is only one.
Use special solar cable and suitable plugs only (wiring should be placed in conduit that is sunlight-resistant or, if
exposed, should be sunlight-resistant) in accordance with local fire, building and electrical codes. Ensure that they are
in perfect electrical and mechanical condition.
Only use solar cables as connection cables. Use connectors of the same type and manufacturer within a solar system,
and compatible connectors to connect the
