Abstract
A solar cell unit capable of easily replacing a film-type solar cell while concurrently using the film-type solar cell and a non-film-type solar cell, and a solar cell unit maintenance system are provided. The solar cell unit includes: a film-type solar cell disposed on a light incident side; a non-film-type solar cell disposed on a side opposite to the light incident side of the film-type solar cell; and a reeling mechanism that reels the film-type solar cell. The film-type solar cell is slidable relative to the non-film-type solar cell by means of the reeling mechanism.
Claims7
A solar cell unit comprising:
- a film-type solar cell disposed on a light incident side;
- a non-film-type solar cell disposed on a side opposite to the light incident side of the film-type solar cell;
- and
- a reeling mechanism that reels the film-type solar cell, the film-type solar cell being slidable relative to the non-film-type solar cell by way of the reeling mechanism, and the reeling mechanism comprising:
- a first case that houses the film-type solar cell that is unused;
- a second case disposed at a distance from the first case so as to provide a power generation region between the first case and the second case;
- and
- a reeling unit configured to reel out, to the power generation region, the film-type solar cell that is unused and housed in the first case, the reeling unit being configured to cause the second case to house the film-type solar cell reeled out to the power generation region.
A solar cell unit maintenance system that performs maintenance of a solar cell unit,
- the solar cell unit comprising:
- a film-type solar cell disposed on a light incident side;
- a non-film-type solar cell disposed on a side opposite to the light incident side of the film-type solar cell;
- and
- a reeling mechanism that reels the film-type solar cell, the film-type solar cell being slidable relative to the non-film-type solar cell by way of the reeling mechanism, and
- the solar cell unit maintenance system comprising:
- an infrared ray image capturing unit that captures an infrared ray image of a surface of the film-type solar cell present in the power generation region;
- and
- a control unit comprising a processor programmed to control an operation of the reeling mechanism based on the infrared ray image captured by the infrared ray image capturing unit.
