Solar modules consist of a number of solar cells that convert sunlight into electrical energy. Photovoltaic modules must be durably resistant to all atmospheric influences in order to be able to reliably generate electricity over decades to come.

Module Process

After the solar cell process, these are joined together using a foil-wire electrode to form a string. SmartWire Connection Technology (SWCTTM) is used to connect the cells. This has many advantages over busbar technology.

The solar cell strings are now positioned on a glass and the encapsulant. A number of strings form the solar cell matrix. In the next stage, the electrical connection of the strings and the assembly of all components takes place.

In the encapsulation process, the individual layers of the solar panel are bonded together under vacuum by means of pressure and temperature. In this way, the solar cells are protected against atmospheric influences and a long service life is ensured. The resulting solar module still has to be fitted with the electrical connection sockets after which it is tested for performance, hipot and electroluminescence.

Our equipment for module production

Meyer Burger’s SmartWire Connection Technology  (SWCT™) is the most cost-effective method of connecting cells using a foil-wire electrode. It has many advantages over conventional cell connection (ribbons) and makes for a significant performance gain. At the same time, the negative effect of possible microcracks can be minimized.

Solar modules are sold according to performance class. Precise performance measurement of the finished modules is therefore important. Meyer Burger offers high-precision measurement systems for modules of the latest generations.
