Abstract

Methods, systems, and computer program products for user-preference driven control of electrical and thermal output from a photonic energy device are provided herein. A system includes a solar photovoltaic module, and a fluid positioned on the solar photovoltaic module. The system also includes configurable reflective surfaces that collect and distribute direct solar and diffuse solar radiation across multiple portions of the fluid and/or portions of the solar photovoltaic module. Additionally, the reflective surfaces is physically connected to the solar photovoltaic module at an angle that is variable in relation to the surface of the solar photovoltaic module. Further, the system includes a controller that modulates an amount of thermal output and/or electrical power output generated by the solar photovoltaic module by transmitting a signal to adjust at least one variable pertaining to the fluid, and transmitting a signal to adjust at least one variable pertaining to the reflective surfaces.

First claim

What is claimed is:

1. A system comprising:
a solar photovoltaic module;
a fluid positioned on the solar photovoltaic module, wherein at least one variable pertaining to the fluid is configurable based on one or more user preferences;
a plurality of configurable reflective surfaces that (i) collect direct solar radiation and diffuse solar radiation and (ii) distribute the collected direct solar radiation and the collected diffuse solar radiation across (a) multiple portions of the fluid and/or (b) one or more portions of the solar photovoltaic module, wherein:
each one of the plurality of configurable reflective surfaces is physically connected to the solar photovoltaic module at an angle that is variable in relation to the surface of the solar photovoltaic module; and
at least one variable pertaining to each one of the plurality of configurable reflective surfaces is configurable based on the one or more user preferences;

a controller, wherein said controller comprises at least a memory and a processor coupled to the memory, and wherein the controller is configured to modulate an amount of thermal output and/or electrical power output generated by the solar photovoltaic module in response to an input of the one or more user preferences by:
transmitting a signal to adjust the at least one variable pertaining to the fluid in response to the one or more user preferences, wherein said adjusting the at least one variable pertaining to the fluid comprises adjusting a height of a layer of the fluid on at least a portion of the solar photovoltaic module to satisfy at least a portion of the one or more user preferences based at least in part on values related to thermal output, electrical power output, absorptivity of the fluid, absorptivity of the solar photovoltaic module, and electrical efficiency of the solar photovoltaic module; and
transmitting a signal to a hydraulic mechanism to adjust the at least one variable pertaining to one or more of the plurality of reflective surfaces in response to the one or more user preferences, wherein transmitting the signal to the hydraulic mechanism comprises transmitting a signal based at least in part on (i) sun angle information related to time-of-day information and (ii) total demand information; and

the hydraulic mechanism coupled to the controller, wherein the hydraulic mechanism adjusts inclination of one or more of the plurality of reflective surfaces based at least in part on the signal transmitted by the controller to the hydraulic mechanism.

2. The system of claim 1 , wherein the fluid comprises water.

3. The system of claim 1 , wherein the one or more user preferences comprise one or more of a total demand of thermal output and a total demand of electrical power output.

4. The system of claim 1 , wherein the one or more user preferences comprise a relative proportion of (i) thermal output demand and (ii) electrical power output demand.

5. The system of claim 1 , wherein the at least one variable pertaining to the fluid comprises the depth of the fluid positioned on the solar photovoltaic module.

6. The system of claim 1 , wherein the at least one variable pertaining to the fluid comprises the velocity of the fluid with respect to the solar photovoltaic module.

7. The system of claim 1 , wherein the at least one variable pertaining to each one of the plurality of configurable reflective surfaces comprises an adjustable reflectivity point of the plurality of configurable reflective surfaces.

8. The system of claim 1 , wherein the at least one variable pertaining to each one of the plurality of configurable reflective surfaces comprises inclination of the plurality of configurable reflective surfaces with respect to the solar photovoltaic module.

9. The system of claim 1 , wherein the modulated amount of thermal output and/or electrical power output is a predetermined percentage of thermal output and/or electrical power output generated by the solar photovoltaic module.
