Systems and methods for selectively producing steam from solar collectors and heaters, for processes including enhanced oil recovery. A representative system includes a water source, a solar collector that includes a collector inlet, a collector outlet, and a plurality of solar concentrators positioned to heat water passing from the collector inlet to the collector outlet, a fuel-fired heater, a steam outlet connected to an oil field injection well, and a water flow network coupled among the water source, the solar collector, the heater, and the steam outlet. The system can further include a controller operatively coupled to the water flow network and programmed with instructions that, when executed, direct at least one portion of the flow through the solar collector and the fuel-fired heater in a first sequence, and direct the at least one portion or a different portion of the flow through the solar collector and the fuel-fired heater in a second sequence different than the first sequence.

Systems and methods for selectively producing steam from solar collectors and heaters are disclosed. A method in accordance with a particular embodiment includes directing a flow of water to a solar collector, directing the flow of water to a gas-fired heater, and, as a result of heating the flow of water at the solar collector and the gas-fired heater, forming steam from the flow of water. The method further includes changing a sequence by which at least a portion of the flow passes through the solar collector and the gas-fired heater.
