Title: PHOTOVOLTAIC POWER GENERATION DEVICE, AND SNOW-MELTING METHOD AND COOLING METHOD THEREFOR
Abstract:
[Problem] In order to promote the utilization of photovoltaic power generation, this invention provides a hybrid energy system comprising: an unpowered snow-melting system that uses a geothermal heat collection system and a heat pipe; and a water-sprinkling system and a groundwater storage tank using a steel pipe pile. [Solution] This photovoltaic power generation device comprises a photovoltaic module (10), a heat pipe (120) that uses groundwater (Q) inside a pile embedded in the ground as a heat source, and a heat-conducting plate (130) affixed to at least the top end (10B) of the photovoltaic module (10). The heat pipe (120) has a heat-collecting section coupled to the groundwater (Q) heat source, and a heat-releasing section that releases heat. A heat medium inside the heat pipe (120) is circulated between the heat-collecting section and the heat-releasing section, and the heat-releasing section is thermally coupled to the heat-conducting plate (130).
