Abstract

The invention discloses a flexible photovoltaic integrated power supply system. The power supply system comprises a physical power supply, a chemical power supply and a power supply controller. Solar energy is converted into electric energy through the physical power supply. A flexible thin film solar battery module is adopted and comprises an amorphous silicon thin film solar battery module, a microcrystalline silicon thin film solar battery module, an amorphous silicon-germanium thin film solar battery module, and a laminated solar battery module consisting of the amorphous silicon thin film solar battery module, the microcrystalline silicon thin film solar battery module and the amorphous silicon-germanium thin film solar battery module, or a copper-indium-gallium-selenium thin film solar battery module. The chemical power supply adopts a storage battery component which comprises a nickel-cadmium battery module, a nickel-hydrogen battery module, a lithium ion battery module, an alkaline-manganese charging battery module or a lead-acid storage battery module. The power supply controller is a solar power supply single output controller with the model of V-ST10, is respectively connected with the physical power supply, the chemical power supply and the load, and is used for regulating and controlling the physical power supply and the chemical power supply. The flexible photovoltaic integrated power supply system provided by the invention has the advantages of good flexibility, light weight, high intensity, good environment tolerance and the like.

Description

technical field [0001] The present invention relates to a new energy photovoltaic system, in particular to a flexible photovoltaic integrated power supply system. Background technique [0002] Solar photovoltaic power generation is a popular and expected energy source among clean and renewable energy sources. The energy that the sun irradiates on the earth can meet all the energy needed by all human beings to survive. Solar photovoltaic power generation was first used on artificial satellites, and general civilian use began around 1994. Although it has only a short history of more than ten years, it has developed very rapidly. Traditional silicon-based thin-film solar cells are deposited on rigid substrates such as glass. This type of solar cell is bulky, heavy, and consumes energy. It can only be used for power generation at a fixed flat position, which limits its application range. [0003] Flexible thin-film solar cells deposited on flexible substrates such as polyester ...
