Solar power generation apparatus

Abstract

To provide a solar power generation apparatus in which even if a plurality of sunshade means are opened / closed simultaneously, a failure diagnosis can be easily made for each solar battery array and a solar battery array having a failure can be separately exchanged.SOLUTION: A solar power generation apparatus equipped with a power conversion device 6 capable of collectively outputting power generated by a plurality of solar battery panels 5, includes: failure detection means 8 that detects a failure in each of solar battery arrays 4 by measuring generated power in accordance with the open / closed states of blinds B1 and B2 detected by open / closed state detection means 7; and opening / closing control means 9 that performs control to set different driving timings of opening / closing driving means 2 to open / close the respective blinds B1 and B2 when an operation of simultaneously opening / closing the plurality of the blinds B1 and B2 is performed by an opening / closing operation device S.SELECTED DRAWING: Figure 1

Claims

A plurality of sunshade means that can be arbitrarily switched between an open state and a closed state; an opening / closing drive means for opening or closing each of the plurality of sunshade means; An opening / closing device that can arbitrarily select a plurality of sunshade means and arbitrarily switch between an open state and a closed state of the sunshade means; an open / closed state detection means for detecting an open / closed state of the sunshade means; a solar cell array in which solar cell modules that receive sunlight and generate electricity are connected in series and which is installed on the sunshade means so as to be perpendicular to the opening and closing direction of the sunshade means; a solar cell panel in which a plurality of the solar cell arrays are arranged in parallel with respect to the opening and closing direction of the sunshade means and connected in parallel; a power conversion device capable of collectively outputting power generated by the plurality of solar cell panels; A solar power generation device comprising: a fault detection means for detecting a fault for each of the solar cell arrays by measuring the generated power in accordance with the open / closed state of the sunshade means detected by the open / closed state detection means; an opening / closing control means for controlling the opening / closing drive means for opening and closing each of the sunshades so that the drive timings of the opening / closing drive means for opening and closing the respective sunshades are different from each other when the opening / closing operation device is used to open and close the plurality of sunshades; A solar power generation device comprising:

2. The solar power generation device according to claim 1, characterized in that when the opening / closing operation device operates to open or close a plurality of the sunshade means simultaneously, the opening / closing control means controls each of the sunshade means to be closed in sequence by a predetermined dimension.

3. The solar power generation device according to claim 2, characterized in that in the process of controlling the opening / closing drive means so that each of the sunshade means is opened and closed in sequence by a predetermined dimension by the opening / closing control means, if the opening / closing operation is stopped by the opening / closing operation device, the opening / closing control means controls the opening / closing states of the other sunshade means so that they match the opening / closing state of the sunshade means with the largest closing dimension.

4. The solar power generation device according to claim 1, characterized in that, when the opening / closing operation device operates to open and close a plurality of the sunshade means simultaneously, the opening / closing control means controls so that after one sunshade means is closed, another sunshade means is closed.

5. 2. The photovoltaic power generation system according to claim 1, further comprising a failure display device which, when a failure of the solar cell array is detected by the failure detection means, displays the sunshade means having the solar cell array in which the failure has been detected and the position of the solar cell array in the sunshade means in which the failure has been detected.

6. 2. The photovoltaic power generating device according to claim 1, wherein said solar cell array is detachable from said sunshade means and replaceable.

7. 2. The solar power generating apparatus according to claim 1, wherein the sunshade means is a blind, a curtain or an awning.

8. 2. The photovoltaic power generating apparatus according to claim 1, wherein the power conversion device performs maximum power point tracking control when outputting generated power from the solar cell panel.

9. 2. The solar power generation device according to claim 1, wherein the sunshade means comprises a blind, and the open / closed state detection means for detecting the open / closed state of the blind comprises a stroke sensor and a slat angle sensor, and when the slat angle sensor detects a value equal to or greater than a predetermined value, a failure is detected by the failure detection means.
