Yes, simply go to the Solution Manager section in your Dashboard to reactivate or duplicate the solution (depending on its status). Then, in the full application (part 2), section 3.1, specify that you also want to apply for the Ocean Solution Label (by ticking the designated checkbox).
Any information from previous applications will carry over, so you won’t need to start from scratch!
You can always contact solution@solarimpulse.com if you have any questions or need guidance throughout the process.
