Reconfigurable solar array and method of managing crop yield using the same
A method and apparatus are provided that combine solar technology and agriculture in a symbiotic relationship that optimizes revenue from both sources. An array of reconfigurable solar collector assemblies is deployed in a crop field. As various crops benefit from varying degrees of shade through their development cycles, and are prone to damage from high winds and hail, the array of adaptable, reconfigurable solar collectors is deployed in the crop field and allows for the easy reconfiguration of each solar collector assembly to vary the amount of shade that is applied to the crops below the assembly, and to provide maximum hail and wind protection when necessary.
1. A method for managing crop yield through varied shading of a crop in the crop field, comprising the steps of:
providing a plurality of reconfigurable solar collectors, each said reconfigurable solar collector comprising:
a telescoping base including a telescoping mounting post extensible from said base and being retractable to a position in which a top end of said telescoping mounting post is positioned below a soil surface of said crop;
a support pole removably mountable on said telescoping mounting post; and
a panel array comprising a plurality of panels, wherein each panel is movably mounted on said support pole from a first, generally horizontal position providing a maximum amount of shade to crops located below said panel array toward a generally vertical position, said panel array mounting at least one photovoltaic cell;
positioning said plurality of support poles on said telescoping bases; and
reconfiguring said panel array to vary a shading over said crop field.
2. The method of claim 1 , said step of reconfiguring said panel array to vary a shading over said crop field further comprising the steps of:
causing said panel array to provide 25% to 100% shade over crops in said crop field from planting of said crops to plant emergence;
causing said panel array to provide 0% shade coverage from plant emergence to a first intermediate development point;
causing said panel array to incrementally increase a percent of shade coverage from the first intermediate development point after plant emergence to a second intermediate development point; and
causing said panel array to further increase a percent of shade coverage to a maximum maturity stage of said plant.
3. The method of claim 2 , further comprising the step of:
after causing said panel to incrementally increase a percent of shade coverage and before causing said panel array to further increase a percent of shade coverage, causing said panel to reduce a percent of shade coverage during a third intermediate development stage.
4. The method of claim 3 , wherein said step of causing said panel to reduce a percent of shade coverage during a third intermediate development stage further comprises reducing said percent of shade coverage to 25% shade coverage.
5. The method of claim 2 , said step of causing said panel array to incrementally increase a percent of shade coverage further comprises causing said panel array to incrementally increase said percent of shade coverage from 25% shade coverage to 50% shade coverage.
6. The method of claim 2 , said step of causing said panel array to further increase a percent of shade coverage to a maximum maturity stage of said plant further comprises causing said panel array to increase said percent of shade coverage to 100% shade coverage.
7. The method of claim 1 , wherein said step of reconfiguring said panel array to vary a shading over said crop field is configured to mitigate crop losses due to at least one of heat stress, drought stress, wind, and hail damage.
8. The method of claim 1 , wherein said telescoping base further comprises a fixed tube having a latch mechanism configured to releasably hold a bottom end of said telescoping mounting post.
9. The method of claim 8 , wherein said telescoping mounting post is spring biased toward an extended position, and wherein said base is configured to automatically move said telescoping mounting post from a retracted position to said extended position upon release of said latch mechanism.
10. The method of claim 9 , wherein said telescoping base further comprises a shaft latching ring affixed to a bottom end of said telescoping mounting post.
11. The method of claim 10 , wherein said latch mechanism further comprises at least one cam latch releasably engaging said shaft latching ring, and a solenoid actuator mechanically engaging said cam latch to release said shaft latching ring upon powering of said solenoid.
12. The method of claim 9 , wherein each said reconfigurable solar collector further comprises a post carrier fixedly attached to an outer surface of said mounting post, a lower shaft support collar fixedly attached to an interior of said fixed tube, and a spring positioned between said post carrier and said lower shaft support collar.
13. The method of claim 1 , wherein each of said panels has a maximum width at a first end thereof furthest from said support pole and a minimum width at a second end opposite said first end, wherein each said panel is movably mounted to said support pole at said second end.
14. The method of claim 1 , wherein at least one panel in said panel array comprises at least one removable panel section.
15. The method of claim 1 , wherein said telescoping base further comprises a fixed tube, wherein said telescoping mounting post is extensible from a top end of said fixed tube.
16. The method of claim 1 , wherein each panel is mounted on said support pole to automatically move in response to excessive wind impacting said panel array.
