Notes Regarding the Installation
To ensure that air can circulate behind the back of the module, an open distance between
the mounting surface and the frame of the module is necessary. This will allow condensation
and moisture to escape.
The modules must be installed in such a manner that air can circulate between the mounting
surface and the module.
Shade, partial shade or soil on the modules lead to a decrease of the electricity yield.
Normal Operating Conditions
PV Products GmbH recommends operating the modules under normal operating conditions.
Installation locations, which do not comply with normal operating conditions or which are dominated
by special conditions, should be avoided. The following normal operating conditions apply for
modules from PV Products GmbH:
The modules are intended for terrestrial use, not for use in space or other special conditions
(see below).
The operating temperature must lie between -40°C and +85°C.
The relative humidity must lie between 45% and 85%.
The module is suitable for wind and snow loads of up to 5,400 N/m².
Special Conditions
The installation location and operating temperatures deviate from the normal operating
conditions.
The installation location is seriously affected by harmful salts.
Snow and hail damage is prevalent at the installation location.
Sand and dust damage is prevalent at the installation location.
Other special conditions, such as air pollution, acid rain, chemically aggressive vapours, soot
and other contaminating factors occur at the installation location.
Specifications
Notes Regarding the Specifications
The specified electrical ratings were measured under standard test conditions (STC) and are
subject to a measurement uncertainty of +/- 3%. The STC are: 1000W/m² of irradiance, 25°C
cell temperature and a solar spectral irradiance according to IEC 60904-3.
Under normal environmental conditions, photovoltaic modules can experience conditions
that result in the production of a higher current and/or voltage as listed under standard test
conditions. Accordingly, the values for short-circuit current (Isc) and open-circuit voltage
(Voc) as specified on the module should be multiplied by a factor of 1.25 to determine the
voltage ratings of components, the rated current of conductors, the fuse sizes and the
dimensioning of the controls, which are connected to the outlet of the PV modules.
