NOVELTY - The operation method involves programmatically determining, for a given time period, a demand for an output of the solar modular array by one or more energy consuming resources at the target location. The efficiency of the solar modular array is affected based at least in part on the determined demand. The programmatically determining process includes determining the demand by several components that utilize heat output or electrical output from the solar module array. The solar module array is affected by controlling devices that affect temperature of the modules in the solar module array.    USE - Operation method for solar module array at target location. Can be used to control solar energy supply systems.    ADVANTAGE - Provides for the control or use of a solar module array, and provides for use of both thermal and electrical energy, as provided by a solar module array that outputs both electrical and thermal energy. Provides a controller control system that can fluctuate or vary an efficiency of the solar module array based on a determined or anticipated energy need. Ensures that controller or control system is provided for enhancing how thermal or electrical energy is distributed. Provides a controller that may be configured to factor in various considerations, such as what loads are best services with energy to minimize utility costs or otherwise service the energy requirements of the target location. Ensures that the control system or controller implements an optimization scheme to optimize cost savings or credits, in which the optimization scheme or plan may be implemented through efficiency fluctuations of the solar module array or energy usage of energy consuming assets. Ensures reduced demand charge, power consumption and total energy costs.
