Abstract

[Problem] To provide a solar cell unit that can be installed near a window and offers improved installation flexibility. [Solution] The solar cell unit 100 of the present disclosure is a solar cell unit 100 to be installed near a window, and the solar cell unit 100 comprises a solar cell 10 and a support part 20 that is attached to a frame part FL near the window and supports the solar cell 10, and the support part 20 comprises a support rod 21 that can be extended and retracted and detachably attached to the frame part FL. For example, the support rod 21 comprises a thick pipe 21A and a thin pipe 21B that is partially inserted into the thick pipe 21A from one side of the thick pipe 21A, and the support rod 21 extends and retracts as the length of the thin pipe 21B inserted into the thick pipe 21A changes relative to the thick pipe 21A.

Description

This disclosure relates to a solar cell unit to be installed near a window, and a method for installing the same. Patent Document 1 discloses a window-type photovoltaic power generation system comprising: a frame positioned inside the window of a building, between the window lintel and window sill; a power generation unit provided on the frame that generates electricity from sunlight incident through the window; and an upper and lower connecting mechanism that connects the upper and lower parts of the frame to the window lintel and window sill. The frame is formed by connecting a pair of vertical frames, arranged horizontally, with the upper and lower parts connected by a pair of horizontal frames. The power generation unit comprises multiple vanes arranged vertically parallel to the horizontal frame, with the longitudinal direction being horizontal; a rotation mechanism that rotates the multiple vanes around a pivot axis arranged parallel to each vane; and solar panels arranged on the outer surface of the vanes. The connecting mechanism includes holding members positioned on the window lintel and window sill that hold the upper and lower parts of the frame and maintain the frame in a vertical position. Furthermore, Patent Document 1 describes a window-type solar power generation system having the above-described configuration, in which a frame equipped with a power generation unit containing solar power generation panels is placed between the window lintel and window sill on the inside of the window section of the building via a connecting mechanism, thereby allowing the solar power generation panels to be installed in the window section simply, easily, and safely. Furthermore, Patent Document 1 specifically states that this solar cell system holds the frame in a vertical position by supporting its upper and lower parts via retaining members positioned on the window frame and window sill. Therefore, it can be easily and simply connected to the window of an existing building, allowing the power generation unit to be positioned in a predetermined location within the window. Furthermore, Patent Document 1 states that because this solar cell system is installed on the inside of a window, it can be used safely and securely even on high-rise windows or non-opening, fixed windows. It also specifically mentions that because the solar power generation panels are installed indoors, measures against strong winds and rainwater intrusion are unnecessary, and the system can be used for extended periods while drastically reducing surface dirt and dust accumulation. Furthermore, Patent Document 1 states that the power generation unit has a structure in which multiple vanes, each with a solar cell panel on its surface, are rotated by a rotation mechanism. This structure also has the advantage of being able to adjust the orientation of the solar cell panels according to the sun's altitude, thereby improving power generation efficiency.
