- Korean Patent 10-0836870 measures the amount of energy incident on a plurality of identically shaped solar sensors installed on the bottom of a perforated cylinder, and measures the position of the sun by comparing and measuring the current generated from each sensor. When the solar cell is perpendicular to the sun or directly incident to the sun, a larger current value is obtained. When the tracking device is moved to have the same current value of each solar sensor, the sun is determined to be perpendicular to the tracking device.
- Korean Patent 10-0904243 has a partition between the light sensor to detect the sun.
- this method has a problem in that the position tracking of the sun is impossible because the difference in the amount of energy generated by each energy absorbing device is small when sunlight is weak or the sun is covered by clouds, such as morning or evening.
- Korean Patent 10-0427690 relates to a cylindrical solar position tracking device equipped with a convex lens on the top surface and four photodiodes installed on the bottom surface, so that the sunlight condensed through the lens shines on four photodiodes equally. Will move.

It provides a device that measures and compares the amount of energy absorbed to track the position of the sun.
- the light absorbing plate since the amount of solar energy absorbed by the focused absorbing plate and the non-condensing absorbing plate is significantly different since the light collecting device is installed, the light absorbing plate operates accurately in the weak sunlight such as morning and evening, and occurs in each absorbing plate. Comparing the amount of energy used, the sun can be determined whether the sun is present or not, and the condenser has no mechanical moving parts and can always track the sun's position.
- the solar light is collected by the column type light collecting device and the collected sunlight is absorbed by the energy absorbing plates
- the amount of energy absorbed by each of the absorbing plates is compared, and the presence or absence and orientation of the sunlight hardly and accurately determine altitude.
- each absorber shows a similar amount of energy or energy ratio, it means that there is no sunlight, and if there is a difference in the amount of energy, it means that there is sunlight.
- the difference in the amount of energy occurs as mentioned above, and the sun is concentrated in the absorber that shows the greatest amount of energy.

- the columnar concentrator 10 of the present invention has a characteristic of having the same transmission, refraction, and condensation, regardless of the angle at which the sunlight is incident in a circular, elliptical, or partial circular cross section. Otherwise, the sun does not need to be tracked and moved, and as shown in FIG. 1, a focal trajectory is made at a position separated by a focal length of the rear of the column concentrator according to the movement of the sun from sunrise to sunset.
- the plurality of solar energy absorbing plates 11 having the same width and the same plate shape are continuously disposed in the circumferential direction at the position of the solar focal trajectory from the sunrise angle to the sunset angle so that each absorbing plate absorbs sunlight.
- the projection area where the absorber plate is in contact with the sun is the same as the top view (above) of FIG.
- the amount of energy absorbed in each absorbing plate has a characteristic related to the projected area of the absorbing plate.
- the absorbing plate receiving the sunlight out of the light collecting device has a unique characteristic value, and the absorbing plates B, C, D that the solar focal point has a significantly high amount of energy see.

- the amount of absorption of solar energy of absorber B changes according to the position of the sun. This phenomenon occurs sequentially in all absorbers, and the position of the sun is due to the change in energy of absorbers that compares and focuses the energy of each absorber. You can check.
- the width of the solar energy absorbing plate is determined according to the physical characteristics such as the diameter, refractive index, and focal width of the light collecting device. For example, when the diameter of the column concentrator is 30 cm and the focal orbit diameter is 50 cm, 80 absorbent plates having a width of 0.9 cm may be disposed on the focal orbit in a semicircle of about 180 degrees with an interval of 0.1 cm. One absorber plate corresponds to about 9 minutes. If necessary, the absorption plates can be arranged in multiple lines to further refine the time interval.
- Each absorber plate is connected to a device for measuring the amount of energy absorbed to calculate the change or rate of change of energy from the amount of energy in each absorber plate, and to determine the position of the sun by comparing the difference in the amount of energy between the absorber plates. In any case, the sun exists over the condenser of the absorber plates with the highest energy levels.
- the energy amount measuring device is a device for measuring the amount of solar energy absorbed by each solar energy absorbing plate by the amount of electrical energy or thermal energy. When the solar cell is used as an absorption plate, solar energy is absorbed by each absorption plate to generate electric current or electric power in the absorption plate, and the energy amount measuring device measures electric current or electric power generated by the absorption plate.
- the energy amount measuring device measures the temperature of the absorption plate It is a device for measuring the amount of thermal energy.
- each absorbing plate has a different diameter but has the same center as that of the light collecting device. The distance of each absorbing plate from the center of the light collecting device is slightly spaced apart to give a difference in the concentration of sunlight. Each absorber is connected to an energy measuring device to determine the degree of absorption of sunlight.
