Abstract

Systems, methods, and apparatuses regarding an improved product dispenser are provided herein. The product dispenser includes a housing and a photoelectric power device disposed on an external surface of the housing. The product dispenser may include a power storage device configured to store energy provided via the photoelectric power device. The product dispenser may also include a motor or pump configured to operate to provide a dispense of the product. The product dispenser components, including the photoelectric power device, the power storage device, and the electric motor may be aligned to operate at a system voltage such that no voltage adjustment relative to an output of the photoelectric power device is needed. This reduces electric power losses. The product dispenser may be configured to perform an installation routine to aid in proper placement of the product dispenser with respect to receiving light for powering the photoelectric power device.

Claims

1. A product dispenser comprising:

a housing;

a photoelectric power device disposed on an external surface of the housing, wherein the photoelectric power device is configured to receive light and convert the received light to output a system voltage;

a power storage device configured to store energy provided via an electrical connection with the photoelectric power device, wherein the power storage device is configured to operate at the system voltage such that no voltage adjustment relative to an output of the photoelectric power device is needed; and

a dispensing mechanism comprising an electric motor that operates to cause dispensing of product from the product dispenser, wherein the electric motor is powered by the power storage device and configured to operate at the system voltage such that no voltage adjustment relative to the output of the photoelectric power device is needed;

wherein operating voltage alignment of the photoelectric power device, the power storage device, and the electric motor at the system voltage reduces electric power losses.

2. The product dispenser of claim 1, wherein the photoelectric power device comprises at least one photovoltaic cell.

3. The product dispenser of claim 1, wherein the photoelectric power device comprises a flexible surface that contours to an external surface of the housing.

4. The product dispenser of claim 1, wherein the photoelectric power device comprises solar paint.

5. The product dispenser of claim 1, wherein the photoelectric power device has a peak power transfer efficiency at the system voltage.

6. The product dispenser of claim 1, wherein the power storage device directly powers the electric motor.

7. A product dispenser comprising:

a housing;

a photoelectric power device disposed on an external surface of the housing, the photoelectric power device being configured to receive light and provide an output power signal indicative of an amount of light being received by the photoelectric device, wherein the output power signal is configured to provide power to at least an electric motor of the product dispenser for operation thereof;

a user interface; and

a controller configured to;

receive an input signal, the input signal being based on the output power signal of the photoelectric power device;

compare a characteristic value of the input signal to a light quantity threshold, wherein the light quantity threshold corresponds to an amount of light received by the photoelectric power device sufficient to support operation of the product dispenser; and

operate, in an instance in which the characteristic value of the input signal satisfies the light quantity threshold, the user interface to indicate that sufficient light is being received by the photoelectric power device to support operation of the product dispenser.

8. The product dispenser of claim 7, wherein the user interface emits visual or audible user feedback.

9. The product dispenser of claim 7, wherein the controller is configured to compare the characteristic value of the input signal in response to transitioning into an installation locate mode.

10. The product dispenser of claim 7, wherein the controller is configured to repeatedly compare the characteristic value of the input signal to the light quantity threshold.

11. The product dispenser of claim 7, wherein the characteristic value of the input signal is indicative of an open circuit voltage of the photoelectric power device.

12. The product dispenser of claim 7, wherein the characteristic value of the input signal is indicative of a short circuit current of the photoelectric power device.

13. The product dispenser of claim 7, wherein the characteristic value of the input signal is indicative of a voltage measured across terminals of a power storage device.

14. The product dispenser of claim 7, wherein the characteristic value of the input signal is indicative of a current through terminals of the power storage device.

15. A method comprising:

receiving, at a controller, an electrical input signal, wherein the electrical input signal is based on an output power signal of the photoelectric power device, wherein the output power signal is configured to provide power to at least one power consuming component of a product dispenser for operation thereof;

comparing a characteristic value of the electrical input signal to a light quantity threshold, wherein the light quantity threshold corresponds to an amount of light received by the photoelectric power device sufficient to support operation of the product dispenser; and

operating, by the controller, in an instance in which the characteristic value of the input signal satisfies the light quantity threshold, a user interface to indicate that sufficient light is being received by the photoelectric power device to support operation of the product dispenser.

16. The method of claim 15, further comprising repeatedly comparing, by the controller, the characteristic value of the input signal to the light quantity threshold.

17. The method of claim 15, wherein the characteristic value of the input signal is indicative of an open circuit voltage of the photoelectric power device.

18. The method of claim 15, wherein the characteristic value of the input signal is indicative of a short circuit current of the photoelectric power device.

19. The method of claim 15, wherein the characteristic value of the input signal is indicative of a voltage measured across terminals of a power storage device.

20. The method of claim 15, wherein the characteristic value of the input signal is indicative of a current through terminals of the power storage device.
