In the soil cultivation system equipped with a solar panel, the space between ridges of a plurality of frame units supporting the solar panels is coupled with a roof member, furthermore, the perimeter surface thereof is integrally covered with a cover unit. In this way, a cultivation house in which the frame units are used as support columns is established. Then, in the solar panels, light transmitting regions are provided, a transmissive member is used as the roof member and thus agricultural plants are cultivated by light passing through the light transmitting regions and the roof member. Furthermore, the cultivation of the agricultural plants is performed in cultivation tanks in which a soil is put, and an appropriate cultivation nutrient solution is supplied through a supply means. In this way, the cultivation environment of the agricultural plants is managed, and thus the agricultural plants can be efficiently cultivated while the burden of an operator is reduced.
