Goldfish could be the first Swiss solar powered submarine

Swiss company BKW FMB Energie is developing a solar powered submarine that will be powered by a floating solar array, saving power on continual trips to shore for recharging. The floating platform, reminiscent of a water-lily design, is made up of a central covered hub that can act as a conference/debriefing or supply center, surrounded by 5 pontoons that are fitted with solar panels. The solar array will cover an area of 300 square meters in total and generate 30 kilowatts of electricity. By going solar, the Project Goldfish sub can stay submerged for unlimited periods, while handling up to 30 people at a time. Passengers will be able to board and leave the sub via a solar powered shuttle.
