The DAS Energy modules are lightweight and to a certain extent flexible. This is because the solar cells are not laminated behind rigid and heavy glass, but between a specially patented barrier film made of fiberglass-reinforced plastic on the front and a durable polyethylene (PET) on the back. In this way, the Austrian manufacturer manages to reduce the weight of a module with 60 cells to 5.7 kilograms.
The module with polycrystalline cells and an output of 255 watts is quite impressive. Even the version with 60 monocrystalline cells does not lag far behind the competition of the standard modules with 280 watts of output. There are also variants with 72 cells and with 24 cells. In the latter, the cells are arranged in two rows, each with 12 cells next to each other, so that a narrow solar track with a width of 354 millimeters and a length of about two meters is created. Project-specific sizes and colours are also possible. Even the shape can be adapted to the specific project within certain limits. (mfo)
