The present invention relates to a device for diagnosing photovoltaic generation. More particularly, the present invention relates to a device for diagnosing photovoltaic generation step by step, capable of preventing an overload in a module diagnosis process by including a string determination part which collects and analyses a sensing value for some of the modules comprising a string and determines whether the string is abnormal, and a module determination part which collects and analyses a sensing value for each module for only the string which is determined to be abnormal by the string determination part, and specifies an abnormal module. |
