After the successful completion of the the EXPO E-Trees in Dubai, Waagner Biro
steel and glass was contacted by Phoenix Contact, a world-leading manufacturer
of industrial automation and connectors, to design and build two rotatable solar
trees for their “All Electric Society Park” at their headquarters in Blomberg, Germany.
This show park was opened for their 100 year anniversary and the solar
trees, tracking the sun during daylight, are one of its highlights.

The design and operating principles of the two solar trees with a 12 m and a 8 m
diameter disc, clad with photovoltaic cells, was developed in a Pre-Construction
Service Agreement together with Phoenix Contact. For this project WBSG was responsible
for the steelwork of the trees and for the mechanical rotation devices,
cladding elements, PV panels and LED features and their cabling works.
After just 5 weeks on site, the two solar trees, with an outcome of the PV cells of
16.3 kWp (12m) and 6.5 kWp (8m) could be handed over to a very satisfied client.
