Detailed Description

Referring to fig. 1 to 5, the cylindrical solar cell of the present utility model employs a plurality of solar panels 10, each solar panel is connected to a cylindrical member (which may be referred to as a multi-sided cylindrical structure) by a panel frame 30, and has a straight prismatic shape, and the solar panels may be disposed on all sides of the multi-sided cylindrical structure, or may be disposed only on a side having a certain illumination intensity, for example, if one side faces north, since only light is scattered in this direction, the side may not be provided with a solar panel (see fig. 3) in order to save the solar panels. However, conventional sheet materials (non-solar panels, e.g., plastic sheets, or metal sheets) may be provided on the sides where the solar panels are not provided, based on aesthetic, protective, or overall strength considerations. For such a polygonal columnar structure, no matter from which direction the sunlight is irradiated, the light irradiated on the polygonal columnar structure is received by the solar cell panel without providing a sun-by-sun system. The configuration associated with the solar cells (e.g., connections between solar modules, solar controllers, and, further, energy storage devices/batteries, etc.) may be in accordance with the prior art.

As a practically preferred embodiment, a polygonal column structure of triangular columns (as shown in fig. 1), pentagonal columns (as shown in fig. 2 to 4), or hexagonal columns may be employed.

When one side face faces forward south, the side face is provided with a crystalline silicon solar cell panel, and the other two side faces are provided with thin film solar cell panels; when one side face faces north, the side face is not provided with a solar cell panel or provided with a thin film solar cell panel, and the other two side faces are provided with crystalline silicon solar cell panels.
