  Here, the abnormality pattern information FF1, which is information indicating the possibility of occurrence of abnormality generated in the above-described steps S128, S136, and S144, generally includes six types of power generation amount abnormality as shown in FIG. Patterns A to F can be applied. In FIG. 17, the abnormal state of the power generation amount data and the correspondence (treatment) to be taken to recover from this abnormal state are shown corresponding to each abnormal pattern. The state corresponding to each abnormal pattern in FIG. 17 is shown using a graph of the amount of power generation corresponding to the solar radiation time. In this graph, the solid line indicates the actual power generation amount, and the broken line indicates the calculated predicted power generation amount (normal power generation amount).

  The abnormal pattern A in FIG. 17 is a state in which no output is detected, and is considered to be a serious system failure. Since the abnormal pattern B is assumed to be a non-critical cause such as a nearby tree overgrown recently, information to that effect is posted only on the homepage for alerting. The abnormal pattern C is a case where the amount of power generation changes drastically, and one failure of the power generation system is assumed. This is considered to be a serious system failure. The abnormal pattern D is a case where the power generation amount gradually changes, and it is assumed that the panel surface of the solar cell array 110 is gradually soiled. As a response in this case, it will be posted on the website.

  Abnormal pattern E is considered to be a non-significant cause due to the influence of the shadows of solar radiation in the case of seasonal variations, so that information is posted only on the homepage. However, if such a state is always maintained, a system setting error or a system selection error is assumed. In that case, the maintenance company is directly contacted. If the abnormal pattern F is determined based on other data and specified to be due to the high temperature of the panel, the abnormal pattern F is posted on the homepage. If the abnormal pattern F is specified to be caused by an abnormal operation of the power conditioner 120, it is sent to the maintenance company. Contact directly.

  As described above, when it is determined that the abnormal patterns A, C, and E are frequently generated and the abnormal condition F is operating abnormally, the CPU 470 performs a predetermined processing procedure. Immediately thereafter, information regarding the state of the abnormal pattern is transmitted to the network terminal 600 (602, 604) of the maintenance company via the network 300. In addition, when it is determined whether a temporary state has occurred due to the seasonal variation of the abnormal patterns B, D, and E in FIG. 17 or when an abnormally high temperature of the panel has occurred due to the influence of the shadow of the abnormal pattern F. The CPU 470 executes homepage creation processing, processes the abnormal pattern information into abnormal pattern information FF1 for the homepage, and registers it in the homepage information database 408.

  The processing procedure of the CPU 470 corresponding to the abnormal patterns A to F detected as shown in FIG. 17 is shown in the flowchart of FIG. In this flowchart, the type of detected abnormal pattern is determined in each step of S250, S252, S254, S256, S258, and S262.

  Then, a process corresponding to the type of the detected abnormal pattern, that is, a process of contacting the maintenance company (S251, S255) or a process of registering the abnormal pattern information FF1 of the personal user information URi (S253, S257) is performed. .

  If an abnormal pattern E is detected, it is determined whether or not such an abnormal state is temporary (S259). If it is temporary (YES in S259), the corresponding personal user information URi is determined. Is registered with the abnormal pattern information FF1. If it is not temporary but frequent (NO in S259), a contact is made with the maintenance company and action is taken immediately (S261).

  When the abnormal pattern F is detected, the detected data is analyzed (S263), and it is determined whether or not the analysis result is due to the high temperature of the panel (S264). The abnormal pattern information FF1 of the individual user information URi is registered (S265). If it is not due to a high temperature, an operation abnormality of the power conditioner 120 can be considered. In that case, a maintenance contractor is contacted and a prompt action is taken (S266).

  As illustrated in FIG. 19, the CPU 470 sequentially monitors the power consumption received from the solar power generation device 100 over time, so that an abnormality or extraneousness of the home appliance indicated by the registered device information FF5 that is the user load 150 is detected. It is possible to discover power consumption, create appropriate advice information, and contact the user on the home page as abnormality advice information FF2.

  As a result of monitoring, if the total power consumption in the user's home shows a change as shown in FIG. 19 during one day, this is the characteristic of the home appliance indicated by the registered device information FF5 corresponding to the user. It is disassembled originally and is represented by power consumption for each home appliance as shown in FIG. For example, as shown in the figure, a device that is turned on / off periodically for a short time with low power is a refrigerator, and a device that is turned on / off together with a resident's activity is a lighting device, which is large when the resident is active and hot. Assume that the one that consumes power is an air conditioner.
