PROBLEM TO BE SOLVED: To provide a generated energy displaying device which can display one-day and one-month integrated generated energy without setting any calendar nor time. SOLUTION: The generated energy displaying device stores the data about the latest one-hour integrated generated energy by overwriting the data in the storing spot where the oldest data are stored. When a generated energy displaying switch 12 is pressed by a user, the device displays instantaneous generated energy in a displaying section 13. When an integrated generated energy displaying switch 14 is pressed, the device displays the integrated generated energy until the then point of time and, when a one-day generated energy displaying switch 19 is pressed, a display control section 17 displays the value obtained by subtracting the oldest data from the latest data stored in a one-day data storing section 20 as the past one-day integrated generated energy. |
