The present invention relates to a bird access preventing device for water solar power generation and a water solar power generation device having the same. More specifically, the present invention relates to a bird access preventing device which blocks birds from accessing a solar module and prevents output decrease and damage of the solar module due to excrements produced by birds, and a water solar power generation device having the same. The birds access preventing device comprises: a first fixing means fixed to one side of a support frame in the longitudinal direction of the solar module； a second fixing means fixed to the other side of the support frame as to be parallel to the first fixing means； and a wire having one end which is wound by the first fixing means, and having the other end which is connected to the second fixing means.본 발명은 수상 태양광 발전용 조류 접근 방지장치 및 이를 구비한 수상 태양광 발전장치에 관한 것으로, 상세하게는, 조류가 수상 태양광 모듈로 접근하는 것을 차단하여 조류가 배설하는 분변으로 인한 태양광 모듈의 출력 감소와 손상을 방지하는 조류 접근 방지장치 및 이를 구비한 수상 태양광 발전장치에 관한 것이다.
