A method and apparatus for the energy management of a portable solar lighting tower is disclosed. The portable solar lighting tower may have multiple modes and functions to adjust the power of the light and adapt the demanded energy of the lighting tower to overlap with the supply of solar energy during the days. Such modes and functions may easily be set and modified using a control panel on the portable solar lighting tower or on an external computer, such as a computer tablet. Additionally, an energy management graph may be displayed on the control panel accessed via the computer tablet that further allows a user to determine whether there exists enough solar energy for the desired power output of the portable solar lighting tower.
