Description

  The present invention cuts a solar module into a rectangular shape with an appropriate size, a first plastic case (1) in which this solar cell module and one of a nickel metal hydride battery, a lithium ion battery, and an alkaline battery and an inverter are built-in, The present invention relates to a portable solar power generator in which a second plastic case (2) in which a solar cell module is built is integrally formed so that it can be bent.

Recently, power generation by burning fossil energy such as nuclear power generation and oil / coal is not only a factor causing global warming and destruction of the environment. Since the economic burden of electricity usage charges is forced, development related to power generation using natural energy such as solar, wind, hydropower, and heat is an urgent task.
Among them, solar power generation is especially expected as a practical power source, but it is expensive and is now popular because it is used for building roofs and parts of electric appliances and parts for lighting. This is not a remarkable situation.
Conventionally, photovoltaic power generation has been used for buildings, and recently, for various applications such as clocks, calculators, and garden lighting.
Several portable technologies have been proposed. Photovoltaic power generation is direct current, and few have an AC conversion device.

Conventionally, photovoltaic power generation is used for various applications such as buildings for large-sized buildings, and recently for clocks, calculators, and garden lighting.

  Conventionally, solar modules have been used in the form of a flat body by placing modules of a certain width on a floor board, and there has been no idea of placing modules in a double layer or winding them.

As a prior art, wind power and a set of solar power generation and lighting fixtures are mainly used as a street lamp, and a solar power generation apparatus itself that can be used freely and has a large capacity and can be carried is rarely found.

Depending on the available power capacity, the size is different, but it is small and has good performance. Some parts need to be replaced in 1 to 2 years, but it is compact and easy to use and store. In addition, it is desired to use portable solar power generation that is free to use, can be used for a long time by charging solar light for 3 to 5 hours at a time, and is inexpensive and durable.

  The invention of claim 1 includes a solar cell module, a nickel metal hydride battery, a lithium ion battery, an alkaline battery, a first plastic case (1) containing an inverter, and a solar cell module. The second plastic case (2) is a portable solar power generation device that is integrally formed so as to be bendable.

With regard to the development and effects of portable solar power generation devices, those that can be easily carried by human hands, those that can be used by many people, and models that use a small simple truck crane and that weigh 500 kg or more per set. Can be produced in a wide variety.
Therefore, it can be used widely for personal use, such as radio, television, computer, lighting, etc., and it is expected that it will be useful for home and outdoor use.
B. The power generation amount is small, and it is possible to manufacture from 1K to 2K watts using truck crane from 10 watts or more. Furthermore, if 1 set or 2 sets are used in parallel, 2K-3K watts can be generated considerably. . Therefore, in addition to support for power supply, surgery, communication, lighting and relief development in areas with earthquakes, floods, conflicts, terrorism, etc., and wide use in the sea and mountains Can do.
C. New battery types will be developed. If the capacity is increased, portable solar power generation can be further applied, and new devices and new functions can be developed.
D. The use of existing solar modules and nickel metal hydride batteries makes it possible to carry it for the time being, so that most people can easily use solar power generation at low cost and global warming. For prevention, the effect of increasing interest in the use of natural energy can be expected, and if it is gradually used even in the home, a considerable advantage can be obtained in the CO2 emission reduction effect.

An embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view of a portable photovoltaic power generation apparatus according to claim 1 invented this time, one of a solar module, a nickel metal hydride battery, a lithium ion battery, an alkaline battery, and a plastic case 1 incorporating an inverter. 2 and 7 are plastic cases 2 containing solar modules, 7 and 6 are lids for the respective housing parts, 3 is an ON / OFF switch, 4 is an AC power supply socket, and 5 is a handle / handrail that can be lifted entirely. And 8 is a strap that wraps and binds the whole.

  With this structure, a slight recess is made between the plastic cases 1 and 2, and this recess is made of a soft material and is easy to store. The plastic case 1 is a little thicker than the plastic case 2, where one of the solar module, nickel-metal hydride battery, lithium-ion battery, and alkaline battery that converts direct current electricity to alternating current, Incorporate an inverter that automatically adjusts the amount of current. The plastic 2 can be inserted and removed even with a slightly thicker solar silicon module.
