Description

Levitation solar power generation assembly {LEVITATION TYPE PHOTOVOLTAIC POWER GENERATING ASSEMBLY}

The present invention relates to a levitating solar power assembly, and more particularly, by attaching a banner to a buoyant body such as an ad balloon and attaching a lightweight flexible solar module like an advertisement to generate solar power in the air, thereby generating electricity for various uses. It relates to a levitating photovoltaic assembly that can save money and is free from space limitations that may occur when installed on the ground.

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

Its characteristics are future energy sources for a sustainable energy supply system.

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

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

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

A photovoltaic module is an aggregate of photovoltaic cells and is 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 amount of light collected per season and average temperature.

During the summer season when the amount of solar light concentration is maximum, overheating of the solar module due to excessive solar radiation causes a decrease in power generation efficiency of 5 to 15% compared to the maximum value.

Rather, it is observed that solar power generation has the highest value in spring and autumn rather than in summer when the amount of light is greatest.

During the winter season, the daily altitude of the sun is low, so the output of solar power generation is generally reduced. Snowfall due to snowfall in the winter season and neglect of the resulting snowfall state are factors that reduce the output of solar power generation in the winter season.

In addition, since flat and wide land is required for photovoltaic power generation, a lot of initial investment is required to secure the site.

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

The prior art connects the solar panels with a flexible joint and raises the solar panels with a base balloon to generate electricity by receiving sunlight from the air.

This prior art uses a wide solar panel to obtain large-scale power generation, and in order to generate a lifting force for such a large-area solar panel, many base balloons are connected and floated. It is disposed on the upper side and serves to generate a buoyancy force on the upper side of the center of the solar panel.

However, although the prior art can expect the generation of buoyancy by the tower balloon, there is a fatal problem that the reduction in power generation efficiency due to the shadow caused by the tower balloon on the solar panel cannot be avoided.
