The energy of solar panel will be particularly efficient when paired with theDFRobot solar power management board. The panels are provided with open holes and copper clasps so that they can be attached directly to the backpack for easy portability and use. The ultra-thin, lightweight design weighs just 90g. It's much lighter than a solar panel in a traditional glass package.
When you hang this panel, make sure the panel is facing the sun and there is no shade covering the solar panel.
