Abstract

A solar tracking system comprises multiple solar panel modules forming a grid of solar panel modules, wherein the multiple solar panel modules are orientatable to a solar source independently of each other; and a control system configured to orient each of the multiple solar panel modules to the solar source independently of each other based on a performance model to optimize an energy output from the grid of solar panel modules, wherein the performance model predicts an energy output from the grid of solar panel modules based on a topography of the area containing the grid of solar panel modules and weather conditions local to each of the solar panel modules.

Claims (8)

1 . A method of initializing a solar tracking system comprising multiple rows of solar panel modules forming a grid of solar panel modules, each of the multiple rows of solar panel modules having a corresponding photovoltaic, each of the multiple rows of solar panel modules independently orientatable to a solar source, the method comprising:

determining a performance model for maximizing an energy output from the grid of solar panel modules, the performance model having control parameters generated from first data, wherein the control parameters are adjusted based on diffuse fraction over predetermined time periods; and

transmitting to each of the multiple rows of solar panel modules orientation commands based on the performance model.

2 . The method of claim 1 , wherein the first data comprise a topography of an area containing the multiple rows of solar panel modules.

3 . The method of claim 1 , wherein the diffuse fraction is based on shading between adjacent ones of the multiple rows of solar panel modules.

4 . The method of claim 2 , further comprising determining the topography.

5 . The method of claim 4 , wherein the topography is determined by laser surveying, aerial surveying, tracking the solar source using energy sensed on the multiple photovoltaics, tracking the solar source using energy sensed on the multiple rows of solar panel modules, or any combination thereof.

6 . The method of claim 5 , wherein the aerial surveying comprises airplane surveys, drone surveys, satellite surveys, helicopter surveys, or any combination thereof.
