Description

Technical Field

[0001] The invention relates to the technical field of solar photovoltaic power generation, and in particular to a solar photovoltaic panel waterproof support system. Background Art

[0002] Solar energy is the energy generated by the continuous nuclear fusion reaction process of sunspots inside or on the surface of the sun. Solar energy has the advantages of abundant resources, longevity, wide distribution, safety, cleanliness and reliable technology. Since solar energy can be converted into many other forms of energy, its application range is very wide. To obtain electricity from solar energy, it needs to be achieved through photoelectric conversion of solar cells.

[0003] In the traditional waterproof photovoltaic panel support system, there is a gap between the horizontal component frames of adjacent photovoltaic panel units, and the waterproof effect is completely dependent on the water guide groove below. In severe weather with strong winds and heavy rain, if the water flow is too large, the wind will blow the rainwater out of the water guide groove. When the water flow is too large, it will even overflow, causing rainwater to seep in, seriously affecting the overall waterproof performance of the support system. Summary of the invention
