| Module sizes
|
should be defined in any case, as
the module area it is the basis for the determination of the module
efficiency. |
| Cells in series
|
should be defined in any case, as
the one-diode model is established for one cell. The program should
know the cell voltage from the module STC values. |
| Cells in parallel
|
is
not used by the model, which considers the module currents as a
whole.
|
| Cell area
|
when defined, the program will be able to compute
a "cell efficiency", normalized to the effective sensitive area,
and characteristic of the module technology.
|
| Module technology and specificities
|
is
a free text for additional characteristics of the module, up to 5
lines.
|
|
|
The
fifth line can be used for the definition of an associated module
in the Sandia
database, or other functional
specificities (AC modules,
Maxim optimizer,
etc) |
| Maximum array voltage
|
is
used during the sizing of the system.
|
|
|
May
be specified according to the IEC standard (usually 1'000 V) and/or
the UL standard for use in the US (600 V). The use of one or the
other option (system situation) will be specîfied in the
sizing parameters of the project. This should be compliant with the
new standard of 1'500V if you want to implement high-voltage
systems.

By-pass protection diodes
This number should be
carefully defined. Each diode defines a sub-module (set of cells
protected by one diode). The sub-module size is used during
the calculation of the electric shading effects.
|
|
NB:
some manufacturers specify 6 diodes in their modules of 60 or 72
cells. This doesn't mean that there are 6 sub-modules, but that the
diodes are doubled (mounted in parallel). In this case PVsyst
expects 3 "operational"diodes, defining 3 sub-modules.
|
Submodule partition
Disposition of the sub-modules within the
module (almost always in length: you have 3 groups of 2 x 10 or 2 x
12 cells). Used in the Module
Layout for the calculation of the electric shading
effects.
| Tile module
|
When the module is integrated in a roof,
sometimes there is a coverage of some parts of the module. This
option allows to specify the visible (active) area when
installed.
|
| CPV (Concentrating)
|
These are special modules for high
concentration.
|
| Bifacial
|
Allows for specifying a module as bi-facial, and
define the bifaciality factor.
