Description

Floating solar power assembly {LEVITATION TYPE PHOTOVOLTAIC POWER GENERATING ASSEMBLY}

The present invention relates to a floating solar power generation assembly, and more specifically, by attaching a light flexible solar module to a floating body such as an ad balloon and attaching a light flexible solar module as if advertising, to generate electricity in various places of use It relates to a floating solar power assembly that is free from the problem of space restrictions that may occur when installed on the ground, as well as being able to save money.

In general, new and renewable energy (New and Renewable Energy) is energy used by converting existing fossil fuels or using renewable energy including sunlight, wind, geothermal heat, biological organisms, and the like.

The future energy source for a sustainable energy supply system is characterized by its characteristics.

Renewable energy has grown in importance due to the instability of oil prices and the response to the regulations of the Climate Change Convention.

In Korea, renewable energy in 8 fields (solar heat, photovoltaic power generation, biomass, wind power, small hydro, geothermal, marine energy, waste energy) and new energy in 3 fields (fuel cell, coal liquefaction and hydrogen energy), total 11 fields are designated as renewable energy.

Among these, solar power generation refers to generating electricity by condensing sunlight on a solar cell or a solar module.

A photovoltaic module is an aggregate of photovoltaic cells and becomes a practical basic unit of photovoltaic power generation.

Due to the nature of photovoltaic power generation, the amount of photovoltaic power generation has variability depending on the seasonal concentration and average temperature.

In summer, when the amount of solar light is at its maximum, the power generation efficiency decreases by 5 to 15% compared to the maximum due to overheating of the solar module due to excessive insolation.

Rather, it is observed that the solar power generation has a peak in spring and autumn rather than in the summer when the amount of light is the maximum.

In winter, the solar power output is generally lowered due to the low daily altitude of the sun. Snowfall due to snowfall in winter and neglect of the snowfall due to it are factors that decrease the output of solar power generation in winter.

In addition, since a flat and wide land is required for solar power generation, a large initial investment is required to secure the land.

Invented from the above point of view, there may be mentioned the same as "levitation type generator" (hereinafter referred to as prior art) of Patent Registration No. 10-1913390.

In the prior art, solar panels are connected with a flexible joint and a base balloon floats these solar panels to receive sunlight in the air to generate electricity.

This prior art uses a wide solar panel to obtain a large-scale power generation, and connects and floats many base balloons to generate buoyancy force for the large-area solar panel. It is disposed on the upper side and serves to generate buoyancy force at the upper center of the solar panel.

However, in the prior art, although the generation of buoyancy force by the top balloon can be expected, there is a fatal problem in that the decrease in power generation efficiency due to the shadow generated on the solar panel by the top balloon is unavoidable.
