Sunfollower is a project inspired by the movement of sunflowers. 

Project Logo

Solar panels are normally positioned towards the cardinal point with the greatest solar incidence, but throughout the day a lot of energy is lost by this fixed positioning.

The idea is to create a public installation, a mixture of a public lamppost, with benches where the public can rest during the day and find a shelter illuminated at night.

The device has two light sensors that rotate the solar panel according to the highest solar incidence, and when there is not a minimum amount of natural light, the sensors activate the lighting of the installation.
