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 computer-implemented method includes automatically modulating an amount of thermal output and/or electrical power output generated by a solar photovoltaic module in response to an input of one or more user preferences by: adjusting at least one variable pertaining to a fluid positioned on the solar photovoltaic module based on the one or more user preferences; and adjusting at least one variable pertaining to one or more reflective surfaces physically connected to the solar photovoltaic module based on the one or more user preferences.

First claim

What is claimed is:

1. A method, comprising:
automatically modulating an amount of thermal output and/or electrical power output generated by a solar photovoltaic module in response to an input of one or more user preferences, wherein the one or more user preferences comprise a relative proportion of (i) thermal output demand and (ii) electrical power output demand, by:
adjusting, based on the one or more user preferences, at least one variable pertaining to an un-partitioned layer of fluid, wherein the un-partitioned layer of fluid is positioned (i) on top of the solar photovoltaic module and (ii) between two or more reflective surfaces that are physically connected to the solar photovoltaic module, and wherein the at least one variable pertaining to the fluid comprises the velocity of the fluid with respect to the solar photovoltaic module, and wherein said adjusting the at least one variable pertaining to the un-partitioned layer of fluid comprises adjusting height (h) of the un-partitioned layer of fluid to satisfy at least a portion of the one or more user preferences (ρ) via:

 wherein E thermal refers to thermal output, E electrical refers to electrical power output, A w refers to absorptivity of fluid, A p refers to absorptivity of the solar photovoltaic module, and η p refers to electrical efficiency of the solar photovoltaic module; and
adjusting at least one variable pertaining to one or more of the reflective surfaces physically connected to the solar photovoltaic module based on the one or more user preferences.

2. The method of claim 1 , wherein (i) said adjusting the at least one variable pertaining to the un-partitioned layer of fluid and (ii) said adjusting the at least one variable pertaining to one or more of the reflective surfaces are carried out by at least one computing device.

3. The method of claim 1 , comprising:
processing the input of the one or more user preferences via a user interface.

4. The method of claim 1 , comprising:
automatically recommending additional adjusting of the at least one variable pertaining to the un-partitioned layer of fluid positioned on the solar photovoltaic module based on a forecast of one or more weather-related parameters.

5. The method of claim 1 , comprising:
automatically recommending additional adjusting of the at least one variable pertaining to one or more of the reflective surfaces physically connected to the solar photovoltaic module based on a forecast of one or more weather-related parameters.

6. The method 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.

7. The method of claim 1 , wherein the fluid comprises water.

8. The method of claim 1 , wherein said automatically modulating the amount of thermal output and/or electrical power output generated by the solar photovoltaic module comprises controlling an average amount of thermal output and/or electrical power output generated by the solar photovoltaic module over a given period of time.

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

10. The method 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.

11. The method of claim 1 , wherein the at least one variable pertaining to one or more of the reflective surfaces comprises an adjustable reflectivity point of the one or more reflective surfaces.

12. The method of claim 1 , wherein the at least one variable pertaining to one or more of the reflective surfaces comprises inclination of the one or more reflective surfaces with respect to the solar photovoltaic module.
