Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a solar power generation system with extremely high reliability and energy efficiency.

Conventionally, it has been common sense to install solar panels facing the sun, tilted from the horizontal by an angle corresponding to the latitude θ of that point, and facing upward. In this case, sunlight irradiates the solar cell panel surface in a y-perpendicular direction, but since the solar cell panel faces upward, if snow, sand, etc. accumulate, the solar cell becomes difficult to operate. In addition, if foreign objects such as leaves or bird droppings are locally placed on the solar panel, the solar cells in that area will not generate electricity, and the resistor will act as a load on other solar cells. This is called a hot spot and has been a major problem in practical solar cells.

Also, depending on the weather conditions, large amounts of electricity or shielding could fall and damage the solar panel surface.

In order to eliminate the above-mentioned drawbacks of the solar power generation system, the inventor of the present invention has already invented a method of vertically installing solar cell channels, and has found that it is extremely effective when snow cover or a reflective mechanism is used. However, when using a fixed solar panel, the solar panel is usually installed facing south, so in the morning and evening when the sun's position is significantly east or west, the sunlight will not be reflected. There was a drawback that the solar cell nozzle was irradiated obliquely, resulting in a decrease in the output of the solar cell nozzle.

The present invention was developed in view of the above points, and is equipped with an automatic rotation mechanism that always orients the solar panel in the direction of the sun, so that it can obtain an almost constant power generation output throughout the day and maintain high reliability. DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a diagram illustrating the principle of the present invention. solar panel 1
is held perpendicularly to the ground 5 by supports 2, and an automatic rotating machine is installed to rotate the solar cell panel 1 to face the direction of the sun while keeping the solar panel 1 vertically.
3) In the morning, when the sun is in the eastern sky, this automatic rotation mechanism 3 causes the solar panel 1 to face the direction of the eastern sun, and rotate the solar cells according to the movement of the sun. Kunel 1 always faces toward the sun and rotates from south to west. The automatic rotation mechanism 3 may include a solar direction sensor and a servo mechanism, but the sun
Since it moves westward from the bundle at a rate of 15 degrees per hour, it may be combined with a simple clock mechanism to rotate at a rate of 15 degrees per hour.

In this way, by providing the automatic rotation mechanism 3 to the vertically erected solar cell panel 1, the solar cell panel 1 always faces the direction of the sun, making effective use of sunlight 4, and fixing the solar cell panel 1 in a fixed position. In the morning, compared to the case of a solar panel that
A constant output is obtained throughout the day and evening, and the total generated power increases significantly.

In addition, there has been a so-called solar tracking type solar power generation system in the past, but this is because the solar panel tracks the sun from the direction perpendicular to the direction of the sun. As mentioned at the beginning, since solar panels face upward, it is impossible to avoid obstacles caused by falling objects. In contrast, in the present invention, the solar panel always remains vertical and tracks only the direction of the sun, which solves all the conventional technical difficulties and ensures extremely high performance. It is.

FIG. 2 shows an embodiment of the present invention, in which a reflection mechanism 6 is also used in order to further improve efficiency. In the east and west directions, the height of the sun is low, so the length of the reflection mechanism 6 is lengthened, and in the south direction, the height of the sun is high, so the length of the reflection mechanism 6 is shortened. In this case, the reflection mechanism 6 is a metal board or a white board installed on the ground 5. The reflection mechanism 6 may be a water surface.

FIG. 3 is a diagram showing another embodiment of the present invention, in which a solar panel 1 and a reflection mechanism 6 are fixed to a support 2 and connected to an automatic rotation mechanism 3 through a common shaft 2. 5. The solar cell panel 1 held vertically and the reflection mechanism 6 are integrated together to track the direction of the sun. Compared to the case of the embodiment shown in FIG. 1, the effective area of the usable sunlight 4 is widened by the addition of sunlight reflected by the reflection mechanism, and the stain removal output is constantly increased.

FIG. 4 is a diagram showing still another embodiment of the present invention, in which a holder 2' that holds the vertically held solar cell nozzle 1 and the reflection mechanism 6 can be rotated using a hinge. and depending on the altitude of the sun, the solar panel 1 and the reflection mechanism 6
The amount of sunlight 4 used is always maximized by changing the angle formed between the two. When the altitude of the sun is high in the daytime, the angle between the solar cell nozzle 1 and the reflective function 6 is small (Fig. 4(a)).

When the sun is at a low altitude, such as in the evening, the angle between the solar cell channel 1 and the reflective function 6 is large (Figure 4(b)).
).

A solar altitude sensor and an automatic control mechanism may be used to adjust the angle of the solar panel 1 and the reflective function 6, but since the altitude and direction of the sun are fixed depending on the time, a clock mechanism may be incorporated to adjust the angle. You can. In any case, rotation control and angle control can be easily performed using conventional techniques.

As explained above in detail, the present invention increases the electrical output toward the sun by keeping the solar panel perpendicular to the ground and providing a rotation mechanism, and the solar panel is equipped with a rotating mechanism to increase the electrical output toward the sun. The effect is particularly remarkable when used in conjunction with the mechanism,
It provides a constant electrical output regardless of the season or time, and maximizes the use of the sun's energy for power generation.
It will make a major contribution to the supply of electricity in various parts of the world.
