- The panel absorbs natural light during the day, whether or not the sun is shining, and transforms it into electrical energy. - The energy is stored by the battery, which can hold enough power to last for a minimum of 45 days of total darkness, based on the shutters opening and closing twice a day. - The battery is therefore able to provide the necessary energy to ensure optimal operation.
