A portable foldable solar photovoltaic cell system

Abstract

The invention provides a portable folding type solar photovoltaic cell system comprising a folding framework, multiple folding components, a controller and a storage cell. The folding components have a multi-piece slide folding structure and each folding component is composed of a slide mechanism and a photovoltaic cell unit, wherein the slide mechanism is composed of a pulley component and a slide groove component. The photovoltaic cell units are packaged on a baseplate which is connected with the slide mechanism. The slide mechanism is operated in a pull-down slide rail laminated piece drag mode. The folding components can suspend at any position with the curved surface facing the sunlight. The photovoltaic cell units include two rows of crystalline silicon solar cells which are arranged in arrays. The two crystalline silicon solar cells of each row and MOS transistors are arranged in parallel, and the rows are arranged in a series connection way so that the hot spot effect caused by the local obstruction can be effectively avoided. The portable folding type solar photovoltaic cell system has the characteristics of being simple in structure, reliable in system and convenient to use so that the system can act as the curtain system of buildings and can also be used in temporary and field solar photovoltaic power generation systems.

Description

technical field [0001] The invention relates to a solar photovoltaic battery system and belongs to the technical field of photovoltaic power generation. Background technique [0002] The sun is the only source that continuously provides energy for the earth. The fossil fuels such as coal, oil, and natural gas that we need in our lives are all because various plants convert solar energy into chemical energy through photosynthesis and store it in the plant. The flora and fauna in the ground have been formed through long geological ages. In addition, water energy, wind energy, wave energy, and ocean current energy are all converted from solar energy. It can be said that the broad sense of solar energy covers a very large range, while the narrow sense of solar energy is limited to the direct conversion of photothermal, photoelectric and photochemical solar radiant energy. Solar energy resources are very rich in the world. In recent years, oil crises have occurred frequently. T...

Problems solved by technology

Of course, there are also its shortcomings: ①The energy distribution density of the irradiation is small, and generally needs to occupy a large area; ②It is greatly affected by weather conditions such as seasons, day and night, and cloudy or sunny

[0006] The standard size of solar cells is 125mm×125mm (2.4W, 0.5V), and the sheet thickness is <1mm. It needs to be connected and packaged on the bottom plate before it can be used. Therefore, the size of the bottom plate is also relatively large. It is relatively small and cannot bear too much weight. To meet the needs of popular application and mobility of solar cells, a base plate with a certain size and rigidity should be used, and the sliding and folding problems between multiple base plates should be solved. Ways of wiring, countermeasures against sunlight shading, etc.
