The total system is designed to be energy negative over its technical lifespan, which is estimated at 15 years approximately. Therefore all energy needed for manufacturing of the components, plus the assembly, can be compensated by the energy production of the tiles during their usage. The energy production however is very much depending on the location and its specific use.
We have several installations that are running for over 10 years and the efficiency is not going down. We keep monitoring energy production and improving our technology to make it more energy efficient.
For temporary installations the energy production does not balance out the energy for manufacture and installation. Here the biggest impact is made by creating awareness with the public about renewable energy and how their behaviour influences the energy in a location.
