1. An oil recovery system, comprising:
a solar steam generator, comprising:
a reflector positioned to receive and redirect solar radiation; and
a receiver positioned to receive radiation redirected by the reflector;
a fuel-fired steam generator coupled in parallel with the solar steam generator;
a steam distribution system operatively coupled to both the solar steam generator and the fuel-fired steam generator to receive steam from both the solar steam generator and the fuel-fired steam generator, the steam distribution system being coupled to at least one oilfield steam injection well; and
an automatic control system coupled to at least one of the solar steam generator or the fuel-fired steam generator and programmed with instructions that, when executed, direct an incoming volume of water to be heated by only the solar steam generator or only the fuel-fired steam generator.
