Floating solar photovoltaic array with on-board energy management system for controlling and powering inflatable support pontoons, water quality, air compression and mooring devices
A floating solar photovoltaic array having an energy management power control system configured to send power clipped by an inverter to the at least one powered accessory device which can be an aerator, a diffuser, a sub-surface agitator, a sub-surface water circulator, a sub-surface positioning/mooring system, a water quality sensor; a panel washer, or a bird removal system. The array has inflatable pontoons and an air manifold system which is powered by the solar photovoltaic modules can be used to adjust the angle of inclination of the solar photovoltaic modules to the sun. The powered accessories can also be powered by unclipped power or on-shore power or combinations thereof which can be controllably adjusted by the energy management control system over time.
1. A mooring system for a floating solar photovoltaic array, comprising:
(a) a plurality of PV modules;
(b) a plurality of floating pontoons for supporting the PV modules above the water; and
(c) an array positioning system configured to perform each of the following:
(i) rotate the array to track the movement of the sun,
(ii) move the array in a straight direction across the surface of the water to a desired location, or
(iii) maintain the position of the array at a desired location on the surface of the water when the array is subjected to forces from wind or waves.
2. The mooring system of claim 1 , wherein the array positioning system comprises a plurality of motors with propellers attached to the floating solar photovoltaic array, the motors with propellers being positioned below the surface of the water.
3. The mooring system of claim 2 , wherein the motors with propellers are attached to the floating solar photovoltaic array in pairs pointing in opposite directions.
4. The mooring system of claim 3 , wherein some of the motors with propellers point inwardly towards the center of the array and some of the motors with propellers point outwardly away from the center of the array.
5. The mooring system of claim 3 , where the motors are bi-directional.
6. The mooring system of claim 2 , wherein the motors with propellers are mounted at side edges or corner edges of the array.
7. The mooring system of claim 2 , wherein the motors with propellers are independently steerable to point in different directions.
8. The mooring system of claim 7 , wherein the motors with propellers are each rotatable about vertical axes.
9. The mooring system of claim 2 , wherein the motors with propellers are angled downwardly to add buoyancy to the array.
10. The mooring system of claim 1 , wherein the array positioning system is powered from power generated by the solar array.
11. The mooring system of claim 2 , wherein the array positioning system further comprises:
(d) a motor speed controller that permits:
different motors with propellers to be operated at different intensities from one another, and
each of the motors with propellers to be operated at different intensities at different times.
12. The mooring system of claim 1 , further comprising:
(d) an inverter on the array for receiving DC power from the PV modules and converting the DC power to AC power such that any power received above an AC Power Limit would be clipped by the inverter; and
(e) an energy management power control system configured to send power that has been clipped by the inverter to the motors with propellers.
13. The mooring system of claim 1 , further comprising:
(d) a plurality of mooring cables connected to the array.
