The invention discloses a split winding structure for solar power generation, which has the advantages of realizing balanced ampere turn between a primary winding and a secondary winding, preventing the windings from being damaged and reducing investment cost and loss. The split winding structure is realized by the following technical scheme that: the split winding structure for solar power generation comprises a first primary winding, a second primary winding and the secondary winding, wherein the secondary winding is wound on an outermost layer; and the first primary winding and the second primary winding are positioned on an inner layer, primarily wound with each other synchronously and lastly wound in a mode of being staggered 180 degrees away from each other.
