A method and system for handling granular material, such as proppant used in hydraulic fracturing in well drilling, is provided. In an operational configuration, a delivery module having conveyors receives and conveys granular material to a delivery location, and one or more mobile storage modules receive, hold and dispense granular material downward to the delivery module. The mobile storage modules comprise a raised, angular container portion for holding granular material. Each mobile storage module may comprise a rock-over chassis for support against ground. A remote control module provides centralized, remote control of the system. Mobile support unit modules may also be provided as a remotely controlled vehicle capable of providing power, control, heating, and the like to other modules. Mobile in-feed elevator modules may also be provided as a remotely controlled vehicle for feeding granular material to mobile storage modules. In a transportation configuration, each module is separately transportable.
