Abstract

The invention discloses a solar photovoltaic power generation device. The solar photovoltaic power generation device comprises an L-shaped support, a rotating rod connected with two free ends of the support in a pivoted manner, a motor for driving the rotating rod to rotate, a first cell panel, a second cell panel, a third cell panel, a rechargeable cell connected with the third cell panel, a photovoltaic panel, a photovoltaic panel azimuth control device, a transmission assembly of the photovoltaic panel azimuth control device and a motor power supply control device, wherein the first cell panel, the second cell panel and the third cell panel are arranged on the rotating rod; the motor works under the control of the photovoltaic panel azimuth control device and drives the photovoltaic panel to rotate to directly face the incidence direction of sunlight; the third cell panel is used for charging the rechargeable cell; the first cell panel, the second cell panel and the rechargeable cell are used for supplying power to the motor alternately under the control of the motor power supply control device. Besides, the invention further discloses a solar photovoltaic power supply system. With the adoption of the solar photovoltaic power generation device and the solar photovoltaic power supply system, the photovoltaic panel can fully absorb sunlight, the output energy is stable, and energy saving and environmental protection effects are realized.

Description

technical field [0001] The invention relates to the technical field of solar photovoltaic power generation, in particular to a solar photovoltaic power generation device and a power supply system thereof. Background technique [0002] At present, with the development of economy and the progress of society, people put forward higher and higher requirements for energy, and finding new energy has become a new topic for current technicians. Since solar power generation has the advantages of cleanliness, safety, and extensive resources that cannot be compared with thermal power, hydropower, and nuclear power, solar energy is considered to be the most important new energy source in the 21st century. At present, solar energy application technology has made great breakthroughs, and has been more maturely applied to local lighting of buildings, urban lighting, solar hot water supply and heating systems. In particular, the development of solar photovoltaic technology has brought broa...

Problems solved by technology

[0004] Using the first method to supply power to the motor has the disadvantage of wasting electric energy. In the second method, since the photovoltaic panel also supplies power to the motor while outputting electric energy, it cannot make full use of the output energy of the photovoltaic panel and reduce the utilization rate of solar energy.
