Solar Cell Handling, Soldering & Mounting
The EnOcean solar cell technology guarantees the highest stabilized efficiency values. At
the front, the solar modules have a glass covering that protects the photovoltaic layer from
the effects of the environment and weather. The rear features contacts for the electrical
connection.
Handling
Prevent injuries due to the sharp glass edges.
Always handle the modules carefully, avoid damage of the glass edges that leads to
glass breakage or glass chips. The layers are sensitive to punctual pressure, scrat-
ching or grinding. During handling and processing, always make sure that no par-
ticles are pushed into the coating. Scratches, imprints or particles pushed into the
layer can lead to short-circuiting of the module, thus deterioration.
The processing of the modules with lacquer spray processes or edge grinding could
lead to an impairment of the electrical function of the module (electrostatic influ-
ences).
In case of necessary module cleaning, the following cleaning agents are suggested:
Kleenex (200 tissues, Code 7107, D 0261 8930, Kimberly-Clark) / highpure DI- wa-
ter / Ethanol (min. 99,8 Vol.%).
Soldering
The solar panel has 3 connection pads on the rear side. On one side you will see the minus
sign. This is the GND connection.
Apparatus
Soldering iron: Temperature-controlled type with 60W heater at least and +/- 5°C
control range is recommended.
Soldering iron tip: Slant type or point type.
Temperature Measuring Device: A calibrated contact-type temperature meter (e.g.
Anritsu Model No. HL-100).
Materials
Pb-free solder wire: Sn96.5/Ag3.0/Cu0.5,
∅
0.8 mm, (e.g. Kester 245)
Lead wire: Dependent on the type of solar cell, use 20 - 30 AWG multi-threads
stranded type. For Pb-free soldering, the lead wire component shall be complied
with RoHS requirement.
Procedure for hand soldering
Environment: Soldering operation shall be performed in a clean environment with
ventilation to remove soldering fume during the operation.
Soldering temperature calibration
o
Temperature measuring device: The device (e.g. Anritsu Model No. HL-100)
shall be stabilized at room temperature prior to and during calibration.
o
Timing: Calibrate the soldering iron tip before the operation or every 30
minutes after the soldering.
