Stretchy type solar photovoltaic assembly and photovoltaic system

Abstract

The invention discloses a stretchy type solar photovoltaic assembly and a photovoltaic system. The stretchy type solar photovoltaic assembly comprises a fixed support and a plurality of layers of solar cell panels, wherein the fixed support is fixed on a supporting face. The fixed support comprises track support bodies. Each track support body comprises a plurality of layers of tracks. The solar cell panels are installed on the tracks. At least one solar cell panel can be stretched out and drawn back in the stretching direction of the track where the solar cell panel is located. The photovoltaic system comprises a carrier and the stretchy type solar photovoltaic assembly which is installed on the top face of the carrier. According to the stretchy type solar photovoltaic assembly, when the solar cell panels are drawn back, the size of the stretchy type solar photovoltaic assembly is effectively controlled, and convenience is brought to carry; when the solar cell panels are stretched out, large-area solar cell panel installation is achieved in a limited supporting face area, the insolation area of the stretchy type solar photovoltaic assembly is effectively improved, and therefore the generated energy of the stretchy type solar photovoltaic assembly is improved.

Description

technical field [0001] The invention relates to a photovoltaic component, in particular to a shrinkable solar photovoltaic component and a photovoltaic system. Background technique [0002] Solar power generation refers to the use of photovoltaic modules to collect solar radiation and convert solar radiation into electrical energy through photoelectric conversion. Abundant sunlight resources make solar energy inexhaustible; and the simple photovoltaic module power generation device reduces the cost input of solar power generation process. High efficiency, energy saving, inexhaustible, environmental protection and no pollution make solar power generation have profound energy development potential, and simple power generation process investment also enables solar power generation to overcome the limitations of traditional urban power transmission and supply networks, even in some relatively remote areas or some nomadic peoples can also benefit from solar power generation. ...

AI Technical Summary

Problems solved by technology

However, in actual operation, due to the large mass of solar panels, it is inconvenient to unfold and store folded photovoltaic modules.

Another example is that although the technical solution disclosed in Publication No. WO2009103726 uses a mechanical support and a rotating shaft to realize mechanical expansion and contraction, the use of the container is greatly limited because the solar panel is directly installed in the container.

However, in the technical solutions disclosed in Chinese patent publication / announcement documents CN1397695A and CN201850649U, the deployed solar panels are directly installed on the top of the moving cavity. Easy installation, disassembly and maintenance of photovoltaic modules
