Events of Particular Importance and Their Repercussions

In order to significantly boost the awareness level of the SolarWorld brand also in the future market of the U.S., the group launched a TV campaign with actor Larry Hagman, internationally known from the TV series “Dallas” playing the part of J.R. Ewing. On the occasion of the trade fair Intersolar America in July, SolarWorld presented five television commercials featuring Hagman.
