Abstract
Abstract An active solar energy system comprising an array of solar collectors, a pumping device to circulate fluid therethrough and a storage tank to contain the heated fluid. The pump is driven by an electric motor and a solar-electric power transducer system energizes the motor, whereby the fluid is circulated through the collector system whenever sunlight is available. The heated fluid from the collector array, as well as the unheated fluid from the source are delivered to a mixing vessel from which the mixture fluid is delivered to a storage tank to meet demands.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
152 words
In an active solar energy system comprising: an array of solar collectors; intake and transfer fluid ducts connected to said collector array; a source of fluid; a pumping device in said intake duct; an inlet line for delivering a fluid from the source thereof to said pumping device; an electric motor conditioned to drive said pumping device; and a storage tank; said transfer duct being adapted to conduct fluid to said storage tank; the improvement comprising; a solar-electric power transducer system exposed to sunlight when available; said transducer system including solar-electric transducers in size and number to generate electricity sufficient to energize and drive said motor; electric conductors connected to deliver an electric current from said power transducers system to said motor; and a mixer vessel connected into said transfer duct and said inlet line upstream of said pumping device, whereby fluid from said collector array and said source will be mixed.
Claim 2
Dependent Claim
152 words
In an active solar energy system comprising: an array of solar collectors; intake and transfer fluid ducts connected to said collector array; a source of fluid; a pumping device in said intake duct; an inlet line for delivering a fluid from the source thereof to said pumping device; an electric motor conditioned to drive said pumping device; and a storage tank; said transfer duct being adapted to conduct fluid to said storage tank; the improvement comprising; a solar-electric power transducer system exposed to sunlight when available; said transducer system including solar-electric transducers in size and number to generate electricity sufficient to energize and drive said motor; electric conductors connected to deliver an electric current from said power transducers system to said motor; and a mixer vessel connected into said transfer duct and said inlet line upstream of said pumping device, whereby fluid from said collector array and said source will be mixed.
Claim 3
Dependent Claim
29 words
The solar energy system defined by claim 1 including; a thermostat controlled heater to heat fluid in said storage tank; and a delivery duct opening from said storage tank.
