Every day, Mohammed Saber places a single rectangular solar panel on the roof of the bamboo-and-tarpaulin shack that he and his family have called home for years, the last stop on their journey after fleeing the Myanmar military's brutal crackdown on the Rohingya in 2017.

The panel is part of a portable solar kit given to the Rohingya refugee family as humanitarian aid six years ago.

It's been the family's primary source of electricity, making daily life so much easier in the camp for the displaced in Teknaf, Bangladesh.
