PROBLEM TO BE SOLVED: To obtain a device for managing a photovoltaic power generation system which makes it possible to sufficiently maintain the targeted amount of power generation by the appropriate management of maintenance contents.SOLUTION: The management device comprises: a solar cell module database 14 in which a degradation prediction model and characteristics data for predicting a transition in the time degradation of output from a solar cell module 19 are recorded; an output decline risk information processing unit 16 for calculating predicted output predicted from an environment condition and a degradation prediction model specified for each of the solar cell module 19 by referring to environment information and location information, and thereby predicting a transition in the output decline of the solar cell module 19 by comparing output information and the predicted output; and a maintenance content management unit 17. When the output information and the predicted output do not match, the output decline risk information processing unit 16 has the degradation prediction model changed, and the maintenance content management unit 17 updates the maintenance content in accordance with the revision of the degradation prediction model by the output decline risk information processing unit 16. |
