(Transmission condition setting process)
The report mail transmission conditions are set from an external terminal such as the operator PC 130 (see FIG. 1). The transmission condition setting unit 206 determines whether there is access for setting related to report mail transmission from the operator PC 130 (step S100).

If there is no access for setting related to the report mail transmission from the operator PC 130 (step S100: NO), the process is terminated. If there is an access for setting related to report mail transmission from the operator PC 130 (step S100: YES), it is determined whether there is a request for setting a report mail transmission condition and a report mail transmission time (step S101).
If there is no request for report mail transmission condition setting and report mail transmission time setting (step S101: NO), the process is terminated. If there is a request for setting the report mail transmission condition and the report mail transmission time (step S101: YES), the transmission condition setting unit 206 sends the above-described report mail transmission condition setting and report sent from the operator PC 130. Save mail send time settings.

  Through the above transmission condition setting process, the sender's email address (the email address of the photovoltaic power generation system monitoring apparatus 200 shown in FIG. 1), the recipient's email address (the business operator's PC 130, the mobile phone 150, etc. shown in FIG. 1). E-mail address of the external terminal), sending time of the report mail (e.g., 8 o'clock, 12 o'clock, 15 o'clock, 18 o'clock, etc.), contents of measurement data included in the report e-mail (e.g., time when the AC power peaked) Is stored in the transmission condition setting unit 206.

(Report email sending process)
The measurement data collection unit 202 collects the measurement data described above from the power conditioner 210 (see FIG. 1), for example, every 10 seconds (step S200).

  For example, when the measurement data aggregation time set every 10 minutes is reached (step S201: YES), the data aggregation unit 204 aggregates the measurement data collected by the measurement data collection unit 202 (step S202). If it is not the measurement data aggregation time (step S201: NO), the process proceeds to the next step S203.

  The measurement data transmission unit 208 determines whether or not the report mail transmission condition set in the transmission condition setting unit 206 is valid (step S203). If the report mail transmission condition is valid (step S203: YES), it is then determined whether or not the report mail transmission time has come (step S204).

  When the report mail transmission time comes (step S204: YES), the measurement data transmission unit 208 transmits the measurement data aggregated by the data aggregation unit 204 to the transmission destination set in the transmission condition setting unit 206 (step S205). ). If the report mail transmission condition is not valid (step S203: NO), or if it is not the transmission time (step S204: NO), the process is terminated.

  As described above, the photovoltaic power generation system monitoring apparatus 200 according to the present embodiment transmits a report mail having preset contents to a specified external terminal at a specified time, and therefore transmits a data request mail from the external terminal. There is no need to do this, and you can view the contents of the measurement data collected by the external terminal.

  In the present embodiment, the transmission conditions and the types of measurement data are illustrated, but the transmission conditions and the types of measurement data are not limited to those illustrated.
