According to the companys press release information, the included solar power app (available for download beginning November 15, 2010) features a lux meter to help you get the necessary light, makes it easy to get at-a-glance information about battery levels, and even alerts you when you need more power.

As you can see the solar panels haven't come about at the expense of design. At just around 0.28 inches thick this is one of Logitechs thinnest keyboards and it uses 'chiclet' keys with a unique contour made to be comfortable when hands are at rest. It is also compatible with the companys Unifying system, the tiny 2.4 GHz wireless receiver that can handle up to six devices at a time, meaning you'll only use a single one of your computers USB ports.
The Logitech Wireless Solar Keyboard K750 is compatible with Windows and Mac OS X systems, though the model being announced today uses a Windows key configuration -- Logitech hasn't ruled out selling a Mac-oriented model though. The device will ship later this month in the U.S. and Europe for $80.
