Recently, various energy sources such as wind power, geothermal power, solar heat, and solar power have been used as alternate energy sources. Among them, solar energy is attracting much attention.

Solar energy refers to energy using solar cells that convert solar energy into electric energy by using the photoelectric effect of light energy. Therefore, if a certain amount of sunshine is ensured, a solar panel can be installed in any area to obtain pollution-free energy.

However, in order to obtain electric energy using solar light, a large number of solar panels need to be installed, and accordingly, a lot of manpower is required and time is consumed.

A large number of solar panels, in particular, are connected by individual cables, which require space for the cable to pass through the frame, and a ducting to accommodate the size.

As a conventional technique for solving such a problem, many solar panels for facilitating cable work have been proposed.

For example, Japanese Patent Laid-Open No. 10-1338616 (registered on Dec. 23, 2013) proposes a photovoltaic power generation device disposed in a center portion including a junction portion to be attached to a front panel and a bus bar to electrically connect the junction portion. .
