PROBLEM TO BE SOLVED: To improve power generation efficiency by securing power generation operation at the back side region of a photovoltaic power generation module utilizing reflection light even at a time zone when the solar altitude becomes low such as morning and dusk.SOLUTION: A photovoltaic power generation panel A comprises a reflection plate 2 arranged at the back side of a photovoltaic power generation unit B group arranged in a planar state spaced out each other, and lets direct incident light inject at the front side region of a photovoltaic power generation module 6 and lets reflection light inject at the back side region reflected by the reflection plate 2 after injecting from a gap space s between photovoltaic power generation modules. Each of the photovoltaic power generation unit B includes: a photovoltaic power generation module 6 about which a plurality of photovoltaic power generation elements 6b are integrated on a film-like plate 6a; a transparent outer tube 7 covering the photovoltaic power generation module from its outside; and a lead wire 10 for generated power which is extended from the photovoltaic power generation module and taken out to the outside of the transparent outer tube. Furthermore, it is characterized in that the photovoltaic power generation module 6 of the photovoltaic power generation unit B is formed in a flat shape in which its height is smaller than its width. |
