1. An array backtracking angle adjusting method, comprising:
acquiring an initial backtracking angle group of a horizontal single-axis tracker; the initial backtracking angle group including initial backtracking angles of a plurality of arrays of the horizontal single-axis tracker;
adjusting, according to a preset deviation angle, the initial backtracking angle group, to determine a plurality of candidate backtracking angle groups; the plurality of candidate backtracking angle groups including adjusted backtracking angles of the plurality of arrays;
determining, according to a degree of dispersion of the adjusted backtracking angles of the plurality of arrays in each of the candidate backtracking angle groups, a target backtracking angle group from the plurality of candidate backtracking angle groups; the target backtracking angle group including target backtracking angles of the plurality of arrays; and
controlling backtracking angles of the plurality of arrays of the horizontal single-axis tracker according to the determined target backtracking angle group.
