Abstract: A solar panel charging display device comprises: a solar panel capable of transforming solar energy into electrical energy; one storage module connected to the solar panel and storing the electrical energy produced by the solar panel; one measurement module connected to the solar panel and the storage module, and capable of generating an electrical signal which is an indication of the electric energy the solar panel generates and transfers to the storage module; and one display module connected to the measurement module and dynamically displaying the voltage or current. Using the display device, the user would easily determine the relationship between the positions or angle of the solar pane and the electrical energy is generating and re-arrange the solar panel accordingly for optimal performance. A method of use of the solar panel charging display device is also provided.
