Abstract

A photovoltaic panel includes: a plurality of power generation portions each having a light receiving surface, each power generation portion including a plurality of power generating elements each configured to generate power in accordance with an amount of received light; and a coupling portion configured to couple each power generation portion, wherein each power generation portion is coupled so as to be rotatable about the coupling portion used as a rotation axis, and the power generation portions are capable of, by being rotated, taking a light receiving position at which the power generation portions are located such that the light receiving surfaces of the power generation portions are oriented to an identical direction, and a fold position at which the power generation portions are located such that a set of the light receiving surfaces of the power generation portions face each other.

First claim

The invention claimed is:

1. A method for manufacturing a photovoltaic apparatus provided with a photovoltaic panel, the photovoltaic panel including:
a plurality of power generation portions each having a light receiving surface, each power generation portion including a plurality of power generating elements each configured to generate power in accordance with an amount of received light; and
a coupling portion configured to couple each power generation portion so as to be rotatable about the coupling portion used as a rotation axis,
the method comprising:
a step of adjusting the light receiving surfaces of the respective electric power generation portions so as to be oriented to face an identical direction;
a step of rotating the power generation portions, to cause the power generation portions to take a fold position at which a set of the light receiving surfaces of the power generation portions are located so as to face each other;
a step of transporting the photovoltaic panel in which the power generation portions are at the fold position;
a step of lifting the transported photovoltaic panel by use of a cord-like member, and carrying the photovoltaic panel to a predetermined position; and
a step of loosening tension of the cord-like member at the predetermined position to rotate the power generation portions and restore the power generation portions to the positions realized immediately after the adjustment of the light receiving surfaces, thereby causing the power generation portions to take a light receiving position at which the light receiving surfaces of the power generation portions are located so as to be oriented to the identical direction

wherein the step of adjusting the light receiving surfaces of the respective power generation portions is performed by adjusting an angle of each power generation portion with respect to the coupling portion,
wherein the adjustment of the angle of each power generation portion with respect to the coupling portion is performed by rotating a push bolt.

2. The method for manufacturing a photovoltaic apparatus according to claim 1 , wherein the step of rotating the power generation portions is after the step of adjusting the light receiving surfaces to face the identical direction.
