In October, a hotel in the northern Chile town of San Pedro called Tierra Atacama announced that they were going fully solar, and shutting down all its diesel generators. That's significant because the hotel is located by the Atacama desert, which is one of the driest places in the world. Switching fully to solar energy is the logical conclusion for the region.
National Geographic reports that the panels were designed by a german company called Kraftwerk, who have used improved lithium ion batteries to create an energy source that will be capable of generating enough power for the hotel to keep them going all day. They need about 100 kWh to run at capacity, but the new solar panels generate about 156 kWh every day, which means the excess power will keep things running at night as well.
