SNOW GUARD STRUCTURE OF PHOTOVOLTAIC POWER GENERATION PANEL

PROBLEM TO BE SOLVED: To provide a snow guard structure of a photovoltaic power generation panel capable of preventing snow drop while ensuring generating efficiency of the photovoltaic power generation panel.SOLUTION: The snow guard structures of a photovoltaic power generation panel for preventing drop of snow accumulated on a photovoltaic power generation panel 3b installed on a pitched roof includes: an accessory panels 5a which is disposed neighboring the photovoltaic power generation panel 3b at the eaves side in an inclination direction of the photovoltaic power generation panel 3b and which forms an even plane with the upper face of the photovoltaic power generation panel; and a snow stopper 6 which is disposed on the accessory panel 5a for preventing drop of snow accumulated on the ridge side of the photovoltaic power generation panel 3b which is disposed at the ridge side of the accessory panel 5a. The length of the accessory panel in the inclination direction is set to a length so that ridge side shadow region S2 of the snow stopper 6 which is generated at the ridge side of the snow stopper 6 does not overlap with the ridge side photovoltaic power generation panel 3b.
