Working Principle of Solar-powered Outdoor Advertising Machines
Solar-powered outdoor advertising machines mainly consist of solar panels, controllers, batteries, and the advertising machine body. The solar panels, as the core component, convert sunlight into electrical energy through the photovoltaic effect. When exposed to sufficient light, the panels generate direct current, which is stored in the battery via the controller. The controller regulates and protects the system, preventing overcharging or over-discharging of the battery. When power is needed, the battery supplies electricity to the advertising machine body, driving it to display advertising content.
