History
The first idea of a public solar charger for mobile devices, Strawberry tree was developed by Miloš Milisavljević, founder of Strawberry Energy company.
As of 2013[update], there were eleven Strawberry Trees installed. The first Strawberry Tree was installed in October, 2010 in the main square of Obrenovac municipality, Serbia. During the first 40 days from presentation of the solar charger, 10,000 chargings were measured. One year later, in cooperation with Telekom Serbia Company, a second Public solar charger for mobile devices was set up in Zvezdara municipality, Belgrade, Serbia. In the same month, a third Strawberry Tree was set in Novi Sad, Serbia. By the beginning of 2012, more than 100,000 chargings had been achieved on all three Strawberry trees.<ref>"Four Innovative Solar Tech Projects From Around the World".
