5 System design
Please use the equipment, connectors, wires and rack which match with solar power system.
In a particular system, be sure to apply the same type of modules. Please refer to the short-circuit
current (Isc) and open circuit voltage (Voc) showing on modules’ label as proper value to install
and design when determining settling parameters such as rated voltage, the wire capacity, fuse,
the controller capacity and module output power of relevant parts of PV system.
In normal outdoor conditions, the generated current and voltage maybe different from the
parameters listed in Table. Parameter table is measured under standard test conditions (STC), so
concerning settling parameters of other parts of photovoltaic power generation system, such as
rated voltage, the wire capacity, fuse, the controller capacity and module power output, it shall
refer to the short-circuit current (Isc) and open circuit voltage (Voc) noted on modules’ label, with
the redundancy value of 125% for design and installation.
Make sure the array of modules installed within the Maximum permitted system voltage and
the rating current and voltage of the sub-equipment such as regulators and inverters.
The connection of modules: in accordance with system design, requirements of output
voltage and current, modules can be series or parallel connected by their connecting wires; the
maximum number of modules in series (N) is equal to the maximum system voltage Vmax divided
by the open circuit voltage Voc of one single module; the number of modules in parallel is related
to the selection of electrical equipment (inverters, controllers) under standard test conditions.
Max System voltage≥N*Voc*[1+TCvoc*Tc(voc)* (Tmin-25)];
N No modules in series;
Voc Open circuit voltage of each module(refer to product label or data sheet);
Tc(voc) Thermal coefficient of open circuit voltage for the module(refer to data sheet);
Tmin The lowest ambient temperature.
5.1 Location Selection

The clamp must overlap the module frame by at least 0.28 in but no more than 0.39 in. All the
installation methods described here are for reference only. We are not responsible for the design
and installation of relevant modules and photovoltaic systems. Mechanical load and safety of
components must be performed by a professional system installer or someone with relevant
qualifications.
• Use at minimum 4 clamps to fix modules on the mounting rails.
• Modules clamps should not come into contact with the front glass and must not deform the
frame.
• Be sure to avoid shadowing effects from the module clamps.
• The module frame is not to be modified under any circumstances.
• When choosing this type of clamp-mounting method, use at least four clamps on each
module, two clamps should be attached on each long sides of the module (for portrait orientation)
and each short sides of the module (for landscape orientation). Depending on local wind and
snow loads, additional clamps may be required to ensure that modules can bear the load.
• Applied torque should refer to mechanical design standard according to the bolt customer is
using, e.g:
