A method includes selectably controlling a power supply from a solar Direct Current (DC) power system and an Alternating Current (AC) power system to a computing system including one or more data processing device(s) using an electronic control system, and continuously updating, through a computing power management system associated with the electronic control system, a power consumption requirement of execution of a high computational workload through the one or more data processing device(s) based on analyzing prior energy usage/production and/or predicted energy usage/production relevant to the execution of the high computational workload. The method also includes optimizing the power supply from the solar DC power system to the one or more data processing device(s) using the computing power management system based on the continuously updated power consumption requirement of the execution of the high computational workload.
