Photovoltaic system

Abstract

The present invention relates to a photovoltaic system which is expandable and collapsible according to the sensing of an illumination sensor, thereby maximizing space utilization; prevents the failure of a solar cell panel due to natural disasters such as strong winds, heavy rain and heavy snow, thereby significantly increasing the lifespan of the solar cell panel; allows a main box cover to be automatically closed and completely sealed when the solar cell panel is lowered after sunset, such that it is possible to easily accommodate and store the solar panel, and thus it is easy to remove, move and install the photovoltaic system when necessary; has an effect in which use efficiency can be further improved as an installation site may be changed and thus a place of use is not limited; accommodates all components in a main box, such that it is easy to repair and replace a part; and enables a user to easily maintain and manage the photovoltaic system remotely by automatic and manual operations via wireless communication.

Description

technical field [0001] The present invention relates to a solar power generation system, and more specifically to a solar power generation system capable of operating solar panels in accordance with the movement of the sun and changes in weather, thereby bringing about the effects of improving power generation performance, protecting solar panels, and extending life , especially, the movable setting brings about the improvement of usage efficiency. Background technique [0002] Generally, solar power generation is used to convert solar energy into electrical energy, including solar panels, batteries, and power conversion devices (micro-inverters). [0003] That is, when sunlight irradiates a solar cell panel in which a P-type semiconductor and an N-type semiconductor are bonded, holes (holes) and electrons (electrons) are generated in the solar cell by the energy of the sunlight. [0004] At this time, holes gather to the P-type semiconductor, and electrons gather to the N-...

AI Technical Summary

Problems solved by technology

[0006] However, the existing solar power generation system as described above cannot be used for other purposes for more than 10 years if it is installed in open space or fields, reservoirs, seas, etc. A large amount of demolition and reconstruction costs are required for new construction, and the applicability of the roof space is significantly reduced

[0007] In addition, since it is fixedly installed outside in an exposed state, it is always exposed to natural disasters unprepared, and has the disadvantage that its lifespan cannot be sustained, such as frequent failures.

[0008] Moreover, because it is a fixed installation, there are problems that limit its use due to the limited amount of sunlight, use only in a limited place where it is installed, and restrictions on the installation direction.
