Solar cells can be built into flexible films in addition to the well-known solar panels. This technology is in full development and the return is getting better.
Two types of films were used in this test set to compare the results: with a width of 37 cm and 50 cm. The installation of the electrical equipment and the pulling of the cables will take place at the end of July. Last year, experience was gained with a small pilot setup. Whether the solar cell trial on the crash barrier is successful will be announced in the autumn of 2019. The next step is to do an investigation on a larger scale, along different types of roads.
It is known that flexible films with solar cells can be used for electricity production. The return is slightly less than that of the known solar panels. The applications are much larger and the performance is improving quickly due to new developments in materials. The partners are working on improved production techniques and new technologies with higher efficiency, which will make solar energy cheaper.
