TPedge

Foil-free PV module


Looking to produce PV modules economically?
Here are three reasons why TPedge is your best choice

1.

Up to 40% cost reduction in PV module manufacturing

2.

Very short cycle time – down to 45 seconds per module

3.

New encapsulation system reduces stress from solar cells

Cost reduction with TPedge


TPedge technology reduces the costs of module production without solar cells by up to 40% – in a short cycle time of only 45 seconds per module line. As a result, the overall cost of a PV module can be reduced by approximately 14%, depending on the cost of the solar cells.

Time and cost savings are a result of a simplified modular structure and completely innovative production technology. The cell array is locally positioned between the two glass units. The use of films and any associated lamination is not necessary. The edge sealing of the TPedge module is carried out by applying the thermoplastic material at 130 °C.

An additional aluminum frame is not even necessary.

Innovative leap in module production

Bystronic glass, now Glaston, developed the technology for the TPedge module production in cooperation with the Fraunhofer Institute for Solar Energy Systems (ISE). Production lines for the TPedge modules can be designed in various expansion stages. In the serial production line, it is possible to manufacture a module in under a minute – compared to the 16 minutes required for the usual standard procedure.

The new production principle has been inspired by the sealing technology used in insulating glass production. The TPedge development process for the production of modules with thermoplastic sealing on the glass edge marks a great innovative leap in the entire module production sector.
