HeliaSol has a very low total weight of less than 2 kg per square metre due to the special layer structure of the solar film, which consists of plastic films and the very thin organic photovoltaic layer. By comparison: conventional solar modules weigh approx. 15-20 kg per square metre, and often have a metal substructure. The low weight of HeliaSol not only offers advantages with regard to use on surfaces with low static load-bearing capacity, but also installation, transport and delivery are easy to manage. A box of 24 films, rolled up and packed in a space-saving arrangement, weighs just over 40 kg and can be carried by two people.
