The present invention relates to a weed-preventing sheet having a reflection function, and more specifically, to a weed-preventing sheet having a reflection function, in which a reflective coating layer is formed by applying a light-reflecting liquid that is composed mainly of a thermosetting resin and glass particles to a surface of a main sheet and thermally curing the light-reflecting liquid such that light can be reflected from the surface of the main sheet, thereby suppressing the growth of weeds on the ground when the weed-preventing sheet is laid on the ground of a photovoltaic power plant, in which the sunlight is reflected by the reflective coating layer provided on the surface of the weed-preventing sheet, thereby further increasing the power generation efficiency of a photovoltaic power generation module with a double-sided photovoltaic power generation panel installed, and in which the reflective coating layer is formed by using glass particles, thereby increasing the reflection efficiency of the reflective coating layer and prolonging the lifespan of the product. 본 발명은 반사기능을 가진 방초시트에 관한 것으로서, 더욱 상세하게는 메인시트의 표면에 빛 반사를 위해 열경화성수지와 유리입자를 주성분으로 하는 빛반사액을 도포하여 열경화시킨 반사코팅층으로 형성하므로서, 방초시트를 태양광 발전시설의 지면에 깔았을 때 지면에서 잡초가 성장하는것을 억제할 수 있음은 물론 방초시트의 표면에 구비된 반사코팅층에 의해 태양광이 반사되어 양면태양광발전패널이 설치된 태양광 발전모듈의 발전효율을 더 높여줄 수 있으며, 유리입자를 이용하여 반사코팅층을 형성함에 따라 반사코팅층의 반사효율을 높여줄 수 있으면서 제품의 수명을 연장시킬 수 있도록 한 반사기능을 가진 방초시트에 관한 것이다.
