The Solar-Powered Clock by Vandasye was created as part of the Vienna Design Week Laboratory, where visitors could see all aspects of the process as a design was being realised. The clock has been designed for interior use, and therefore has a large solar-power to absorb as much light energy as possible.
Despite the slightly odd appearance, it’s one of the first solar clocks that I’ve seen that also include a backlit display for night time. The energy consumption of a LCD clock is very low, however, the backlight increases the power requirements significantly. That’s probably the reason for the large solar panel.
The design is a prototype, so I’m not sure we’ll see it in the shops anytime soon.
