The solar panel Maroshi is light and flexible so that you can take it with you wherever you go. We encourage you to be creative in finding the best spot to catch the sun. It could be attached to your window, laid on the grass in a park or leaned on your balcony wall. The more the panel is in direct sunlight, the greater the energy production. NOTE: Your Maroshi solar panel is flexible but not unbreakable. So please take care of it and don't overbend it, because this will damage the solar cells.
