Description

Photovoltaic Power Generation Equipment using Pipes}

The present invention relates to a water-based photovoltaic device using a pipe, and more particularly, to a water-based photovoltaic device using a pipe to enable photovoltaic power generation in the sea or rivers, rivers and the like.

In general, energy is limited to fossil energy such as petroleum, coal, and natural gas, and has a problem of emitting pollutants.

Therefore, the development of alternative energy that can be used to replace this is important, the most attention among them is the solar power generation using solar light.

The solar power generation technology is a principle that can easily obtain power by receiving light and converting it into electrical energy. Therefore, it is a clean power generation technology that can change the pollution-free sunlight into electric energy indefinitely, and there is no pollution such as air pollution, noise, heat generation and vibration.

It can also have a semi-permanent life that requires little fuel transportation and maintenance of power generation equipment.

Photovoltaic utilization technologies include solar cell utilization technology that converts solar energy into electrical energy through solar cells consisting mainly of solar cells, and solar energy utilization technology that directly uses solar heat energy through collectors.

Solar cells are semiconductor compound devices that convert solar energy directly into electricity, and are manufactured to a thickness of 0.2-0.5 mm. The structure of the solar cell is a p-n bonding structure made of a p-type semiconductor made by impregnating phosphorus, arsenic, antimony, etc., with pentavalent elements on silicon.

When solar light having energy greater than the forbidden bandwidth of the p-n junction enters a solar cell composed of a pn junction, electromotive force is generated by a photoelectric effect, and an electric current flows when a load is connected to the outside. Using this principle, solar cells can be connected in series and in parallel to produce the electricity needed for industry.

A solar cell refers to a semiconductor unit device that converts solar energy into electricity, and a solar panel refers to a power generation unit manufactured in a small area unit manufactured by considering a durable environment by electrically connecting a plurality of solar cells.

Solar cells do not get enough output with a single cell, so each cell must be connected in series or in parallel. This connection is called a "solar panel."

The solar panel is composed of a back sheet, a solar cell, a ribbon and EVA glass. The back sheet is a material that is laid at the bottom of the module, and a TPT (Tedlar / PET / Tedlar) type is widely used, and a ribbon is used as a passage through which electric current flows, so a material coated with copper or silver or tin lead is used.

Photovoltaic devices are often equipped with a solar tracking function for efficient light reception of the solar light, the solar tracking device has to rotate a huge solar panel, it is expensive to manufacture a driving device for driving the solar panel There is a problem.

In addition, since it is necessary to maintain robustness against an external natural environment such as a typhoon, there is a problem in that a large amount of power is consumed even when driving a motor due to large inertia of a structure.

In addition, there is a problem in that solar power generation requires a relatively large area due to low energy conversion efficiency. That is, since a solar cell uses a planar solar cell module having a structure in which a matrix (rows and columns) is arranged on a plane, a large area is required to produce a large amount of power.

However, such an increase in area may place restrictions on the installation site and the like, and may increase the cost. In addition, the planar solar cell module may be easily damaged by rain, hail or wind, and there is a problem that power efficiency varies greatly depending on the direction in which sunlight is irradiated.

In addition, photovoltaic power generation has a low energy density, so many solar panels are installed on the land which is several kilometers long, and it is difficult to find suitable installation place due to lack of land for installing many solar panels. The high land prices make it difficult to buy for solar power, and it is difficult to find a sunny place.

Therefore, securing a space for installing a solar panel is a challenge of photovoltaic power generation.

As a way to secure the installation area, it can be considered to install on the surface of rivers, lakes, reservoirs, dams, seas, etc., where the amount of sunlight is abundant and the open area can be easily secured.

In the conventional water-based photovoltaic power generation system, the angle of the solar cell panel is fixed, so that the solar light is not properly irradiated to the solar cell panel according to the position of the sun which changes according to the change of season and time, so that the power generation efficiency is inferior.

For example, Patent Document 1 discloses an 'aquatic photovoltaic power generation system'.

The water photovoltaic power generation system according to Patent Document 1 includes a solar cell array composed of a plurality of solar cell modules, and a bracket coupled to a rear surface of the solar cell array to support the solar cell array.

With a unit.
