Embodiment Construction

[0020] see figure 1 , which is a structural schematic diagram of a preferred example of a solar photovoltaic-hydrogen energy storage power generation system of the present invention. As shown in the figure: the solar photovoltaic cell 1, the power source of the system, is electrically connected to the power distributor 2 through wires. The principle of photovoltaic cell power generation is to convert light energy into electrical energy by using the photovoltaic effect characteristics of semiconductor materials. The I output port of the power divider 2 is electrically connected to the input end of the DC load 6 through a wire, and the II output port is electrically connected to the input end of the electrolytic cell 3 through a wire. The power generation of the photovoltaic cell is responsible for reasonably distributing and outputting the generated electric energy to the DC load 6 and the electrolytic cell 3 . The capacity matching of solar photovoltaic cells and electrolyzer...

Abstract

The invention relates to a solar photovoltaic-hydrogen energy storage power generation system, in particular to a novel high-efficiency solar photovoltaic-hydrogen energy storage power generation system, which comprises a solar photovoltaic cell, a power distributor, a direct current load and an energy storage power regeneration device, wherein the solar photovoltaic cell serves as a system power source; and the energy storage power regeneration device consists of an electrolytic bath, a hydrogen storage tank and a fuel cell. By the system, the main technical problems of low energy storage density, short energy storage time, short service life, high leakage rate, high failure rate, environmental pollution caused by scrapping and the like of the conventional solar cell are solved. Compared with the conventional solar photovoltaic energy storage system adopting a storage battery as energy storage equipment, the energy storage power regeneration device of the system has the advantages of long energy storage time, high energy storage efficiency, low running and maintenance workload, no anti-reverse charging diodes and the like. The system fully utilizes renewable energy sources, has the advantages of energy saving, environment friendliness and the like, and can be popularized and used in places such as remote mountainous areas, islands and the like with sufficient sunlight but insufficient utility power.

Description

technical field [0001] The invention relates to a solar energy system, in particular to a solar photovoltaic-hydrogen energy storage power generation system. Background technique [0002] With the development of society and the improvement of people's living standards and environmental protection awareness, it is imminent to find environmental protection and renewable energy. As a clean, renewable and resource-rich energy source, solar energy has incomparable advantages over fossil energy sources. Therefore, the development and utilization of solar energy has attracted the attention of more and more research institutions. [0003] At present, most solar photovoltaic power generation energy storage methods use battery energy storage. Although battery energy storage can meet the requirements of continuous load operation around the clock, battery energy storage itself has defects that cannot be ignored, such as short energy storage time, easy leakage, and short service life. ,...
