Composite power generation device and system

Abstract

This invention relates to a composite power generation device that can provide simultaneous or selective combined solar and wind power generation. It comprises: a base fixed to the ground or roof; two poles attached to the base, positioned opposite each other and spaced apart, each pole equipped with a wind power generation unit and a warning light at its top; a solar power generation unit with a flat blade mounted on it and pivotally connected to two joints between the two poles, the flat blade having a solar panel on both its front and back sides, and a solar tracking unit connected to the two joints; and a control unit mounted on the base or the two poles, electrically connected to the solar power generation unit and the solar tracking unit.

Claims

1. A composite power generation device comprising: a base for fixing to the ground or a roof; two poles attached to the base, facing each other and spaced apart, with a wind power generation unit on each pole and a warning light at the top of each pole; a solar power generation unit, having a flat blade mounted on it and pivotally connected to two pivot points between the two poles, with a solar panel on both the front and back of the flat blade, and a solar tracking unit connected to the two pivot points; and a control unit disposed on the base or the two poles, and electrically connected to the solar power generation unit and the solar tracking unit.

2. The composite power generation device as claimed in claim 1, further comprising an energy storage unit, wherein the energy storage unit is installed inside the base, at the bottom of the pole and / or on the outer side of the base, and the energy storage unit is electrically connected to the control unit.

3. The composite power generation device as described in claim 2, wherein the solar panel is provided on both the front and back sides of the flat plate fan blade.
