The present invention relates to a mobile photovoltaic device, and more specifically, by mounting a solar panel on each of a plurality of sides of a movable frame rotatably with respect to the upper end of the frame to fold the solar panels on the side of the frame. It relates to a portable photovoltaic power generation device that stores and moves, and expands at least one solar panel according to field conditions in the outdoors to generate electric power using sunlight.

As concerns about environmental problems and energy depletion grow, interest in power generation using sunlight as an alternative energy with abundant energy resources, no environmental pollution problems, and high energy efficiency is increasing. In particular, research and development of photovoltaic power generation that converts sunlight into electrical energy using a solar panel is being actively conducted. Such photovoltaic power generation is greatly affected by power generation efficiency according to the amount of sunlight, the number of solar panels, the area, and the like.

Recently, as national income has increased and many companies have implemented a five-day work week, interest in personal welfare and hobbies such as leisure is increasing. Accordingly, the number of people who enjoy outdoor activities such as camping or fishing as one of their leisure activities, and holidays at weekend farms or farm houses on weekends is rapidly increasing.

In addition, due to the development of various outdoor electric devices or electronic devices, as electricity consumption increases even in outdoor activities, the battery is frequently charged using a vehicle. To this end, when the battery is charged while the vehicle's ignition is on, soot and fine dust are generated, thereby increasing the problem of environmental pollution. In order to solve this problem, as one of several methods, a portable or portable solar power generation device has been developed and commercialized.

Therefore, power generation can be easily and conveniently used even in these outdoor activities by using a portable or portable solar power generation device. In addition, the portable or mobile solar power generation device can generate and utilize electricity by using it at home or in the office, and thus has the advantage of conserving energy and contributing to environmental preservation.

According to this trend, portable photovoltaic power generation devices that can easily perform photovoltaic power generation outdoors have recently been developed, and various types of loads in outdoor activities, for example, portable electronic devices that consume high power, such as smart phones, have been developed. As outdoor electric devices used for camping or similar situations develop, various types of portable solar power generation devices are being developed to satisfy customer needs.

These existing portable photovoltaic power generation devices have been developed to be miniaturized, foldable, or movable according to their use, but are still often insufficient in portability, mobility and convenience due to their size, volume, and weight. In addition, in the case of miniaturization for portability and mobility, the solar power generation efficiency is not very high due to the limitations of the size and area of the solar panel, so it is insufficient to satisfy the needs of customers. Accordingly, there is a demand for product development for various capacities or models with improved portability, mobility, and convenience of photovoltaic devices.
