Solar park

Organic solar cell solar park

The solar park is based on polymer solar cells developed in house and is the first ever organic solar cell park. The energy payback time for the practical installation of polymer solar cells on the wooden 250 square meter platform is 180 days when operated in southern Spain. In Denmark where the current installation is located the energy payback time is 277 days.

Installation and de-installation rate have been demonstrated to be above 100 m/min (see the video below). This makes the solar park installation extremely fast in comparison with all existing solar cell technologies.

You can read more about the solar park in the article "Rise to power - OPV based solar parks". The article is open access.
