Solar panels do not have the ability to store electricity on theirown.A power bank is required to store the energy generated.The stored energy can then be used to charge your devicesdirectly. The efficiency of solar panels is influenced by weatheconditions and the intensity of sunlight.lt is advisable not toexpose smartphones and power banks to direct sunlight toprevent overheating.

Design of Parallel CircuitsIn parallel circuits, each of the 4 parts of the solar paneloperates independently. Even if one part is damaged, the systemwill still function properly and reliably. Operating temperaturerange:-20°C to 65°CRegardless of the season, as long as there is sunlight, thesystem can be utilized. The output power is more effective whensunlight is intense.
