Solar notebook
A solar notebook or solar laptop is a laptop computer with batteries that are recharged by a solar panel attached to the notebook.

Features 
Unlike regular laptops, some models of solar notebooks come with a flap-like structure which functions as a solar panel and can be removed if required. This generates the electricity required to charge its batteries. Like many other laptops, they may include features such as Internet access, GPS and satellite phones. Other models feature external solar modules connected to the laptop and solar keyboard chargers, where the keyboard looks like a solar sheet with the outline of a keyboard imprinted on it. Samsung has integrated the solar panel in the cover (back side of the display)
