After more than two years in continuous operation of the first systems the project team which supports the manufacturer and customer makes a first summary.
Besides the absolute reliability and measuring accuracy another intended side effect became evident. Rather than using the simulator only at the end of the line for the quality rating of the modules as before, the “ProMoSim” serves today as an indicator for the process optimization and contributes in this way to an improved product quality and increased output.
Non-contacting brazing
in the past few months, Strama-MPS has with its contacting system “ProMoBraze” another asset for the production of PV modules. For the first time the extremely economical induction brazing may also be used for the connecting and interconnecting of thin-film modules.
Besides the decreasing material and process costs in contrast to the self-gluing technology, the high service life of the brazed connections, above all, is a crucial aspect of applying this procedure. As is standard in the automotive industry and its component suppliers, the developers at Strama-MPS already integrated as requirement into the concept for both systems not only the compact design but also a maximum flexibility in processing various types. Of course, the switchover to different module sizes is made fully automatically.

Hi-Bond Tapes Ltd www.hi–bondtapes.com
Quality solutions for the solar industry
Hi-Bond acrylic foam tapes ensure quality long term structural bonding essential for the high demands required by the solar industry. Our high performance tapes are formulated to withstand the most rigorous climatic conditions over prolonged periods without deterioration in performance levels. The unique characteristics of the foam tape give strength levels that cannot be matched by conventional adhesive tapes such as polyethylene, polyurethane tapes or silicones. The temperature resistance is from -40o to + 160o
C C these tapes withstand high humidity even at elevated temperatures.
The acrylic foam is visco-elastic; this property gives excellent expansion/contraction co-efficiency at high and low temperatures on glass, aluminum, plastics and backing films. Load bearing capability is exceptional with very high dynamic shear and tensile adhesion values, resisting very high wind forces and heavy snow loads.
Exposure to high levels of U.V. light over prolonged periods can be withstood with no degradation and discolouring.
These tapes are environmentally friendly with no solvents being used in the manufacturing process, with no outgassing which can damage electrical circuits. Applications in the solar industry are bonding modules to frames, a range of thicknesses are available that can accommodate different profiles and lamination thickness.
We supply rolls and spools for fully automated lines to improve productivity by speeding up the whole
process. We also produce precision die cuts for junction box mounting for both crystalline and thin film modules. Our tapes give a complete seal with instant bonding whether applied by hand or automated systems. The 6 series grades of acrylic foam tapes are UL approved. Thicker grades of tape are available for backrail bonding for large thin film modules for ease of installation. We also have tapes for cell fixing and electrically conductive tapes for buzz bars.
Hi-Bond tapes is your ideal partner for bonding solutions in the solar industry when manufacturing either thin film or crystalline modules.
HF induction brazing of thin-film modules
Helmut Petzko, Managing Director of Strama-MPS, feels confident that the solar industry will continue to be an important economic engine for the mechanical and plant engineering in Europe. ”In particular the reliable and quick process handling of PV modules is a real challenge for the automation specialists. Sooner or later we will hit on new limits for the interaction of speed and precision, and that is when in addition to the experience also the whole innovative strength of our branch is put to the test.“
