TECHNICAL CHARACTERISTICS
Helios Solar Works solar modules belong to the latest generation of mono-crystalline and multi-crystalline 6
in. (156mm) cells. heir contoured surface and triple conduction band systems provide higher generating
power and homogeneous aesthetics.
Each module consists of 60, 72, or 96 high-quality cells in serial configuration to achieve optimal power and
voltage for photovoltaic systems, either connected to the grid or not.
Before designing, assembling, operating, or proceeding with the maintenance of the 6 , 7 2 and 9 6
Series photovoltaic module, please carefully read all of the instructions and recommendations in this
manual.
Helios Solar Works disclaims any liability for breakage, deterioration or the loss of performance of any of
our modules resulting from the incorrect installation, use, and/or maintenance.
he junction box has a level of protection of IP65 against infiltration of dust and water and houses the
connection of the metallic output bands of the module to the cables (positive and negative). he bypass
diodes are connected inside the junction box ensuring the thermal stability of the cells in case of shading
during the hours of irradiation.
wo isolated copper cables, 4mm
2
(see annex A for AWG mm
2
sizing) and 1.2 m long emerge from the
junction box. Each cable is connected at its end with MC compatible plugs, one male, and one female,
which facilitate the connection of the modules by forming serial connections to reach the adequate voltage
for the system.

In order to protect the module against electrical shorting, fast acting fuses of 15 amps are to be used when
connecting in series.

he maximum power value, open circuit voltage and short circuit current of any individual module will be
-0% to +3% of these values. Specifications are subject to change.
Electrical Values
In actual conditions, the variation of the parameters of operation for the cells will be related to the variation
of irradiation received and the actual temperature. hese parameters show the indicated values in the
previous charts.
he variations of the working point of the model according to the modification of different operation
parameters are shown in the next page.

Potential Power Curve
Figur 4. Curv of th pot ntial produc d by a photovoltaic modul in r f r nc
to th working point.
In the above figure, it can be observed that there is a point for which the product (I x V) reaches its
maximum. his point, called the maximum power point, determines the expressed peak power using the
units (Wp).
he ability of the system to trace this point in relation to the variation of working conditions of the module is
called, "tracing of the point of maximum potential (MPP )".
