Brightness refers to how the human eye perceives the intensity of a light source.
Brightness is measured in Lux [lx]. The human eye can perceive various light
sources with the same brightness. Depending on the technology, solar cells have
varying degrees of efficiency for daylight and artificial light. Fluorescent lights
require at least 30% greater brightness to generate the same level of charging as
daylight.
The value of the product light (Lux) and duration (h) are referred to as Lux h.
The amount of available daylight in the winter is minimal. Winter must be used for
calculations if the intent is to guarantee functionality. Of further note is that
illuminance differs on horizontal versus vertical surfaces. As a matter of principle,
horizontal surfaces are better than vertical, of course with the exception of roofs.
The following minimum conditions must be guaranteed for the mounting location of
STM solar cells:
· Check the STM initialization parameters as described in the user's guide.
· Check light sources (daylight or artificial light). Assume a worst case involving
fluorescent lamps if the light source cannot be clearly defined.
· Define minimum brightness and duration of illuminance required to ensure
operation.
· Check lighting conditions on the planned mounting location for the module
assuming the least favorable conditions (e.g. in winter).
The energy cell drains too much if the average illuminance drops below the
defined, indicated values and transmission ceases. Transmissions resumes
automatically as soon as the energy cell is sufficiently charged.
The list provides typical illuminance values. Please use a Lux meter to measure
actual values.
A satisfactory Luxmeter is available as of EUR 30.
