Thereafter, the AC power output from the solar cell protection unit 5 is measured by the generated power meter 7 via the AC regulating opening and closing unit 6, and thereafter, through the home distribution panel 8, the heating device of each household ( 9) is applied.

However, the method and apparatus for utilizing solar energy as a heating boiler fuel source according to the prior art prevents the solar cell module from operating normally when the weather is cloudy, in particular, when the solar heat is not properly input by snow, rain, and earth rotation. There was a problem that can not generate power.

In addition, when the weather is clear, more power is produced than the amount of power required for heating of each home, and there is a disadvantage in that conventional surplus power cannot be properly utilized to maximize the function as alternative energy.

On the other hand, the generated power connected to the conventional heat collecting plate structure is charged to the battery, the power is not charged at night or cloudy days without sunlight may be a sulfate generated from the battery.

And a switching unit for connecting and disconnecting the battery to and from the battery, and a control box for controlling the solar cell unit, the power controller, and the switching unit.

According to the present invention, since the solar panel collects sunlight while rotating along the direction of the sun, there is an advantage that can absorb a large amount of sunlight.

In addition, the present invention has the advantage of preventing the fixing of the sulfate in the battery by charging the home power when there is no sunlight, so as not to generate a time that is not charged.

In addition, the present invention has the advantage of heating the boiler using a separate heating means when there is no sunlight.

And a control box 70 for controlling the solar cell unit 10, the power controller 20, and the switching unit 60.

Here, the DC current produced by the solar cell unit 10 is charged in the battery 30 by the power controller 20. At this time, the control box 70 controls the power controller 20 to supply the power charged in the battery 30 to the boiler 40 to be used for heating. At this time, the battery 30 may be further provided with a capacitor 31 that can be charged with the remaining current remaining after the charge. That is, the battery 30 and the condenser 31 may be provided together to increase the amount of charging power.

When the solar light is not collected, the control box 70 may control the switching unit 60 to supply the external power of the external power input unit 50 to the battery 30 to charge it. In this case, the switching unit 60 preferably includes a DC converter when converting an AC current, which is an external commercial power source, into a DC current. In addition, the switching unit 60 preferably uses a relay.

The solar cell unit 10 includes a solar panel 11 absorbing sunlight, a rotating shaft 13 connected to the lower portion of the solar panel 11, a driving motor 15 rotating the rotating shaft 13, and And solar cells 17 disposed on both sides of the solar panel 11 to compare the sensing values of the plurality of solar sensors 17 and the plurality of solar sensors 17 to control the driving motor 15. It may be configured to include a panel control unit 19.

Here, the plurality of solar sensors 17 sense and track sunlight, and are preferably disposed on both sides of the solar panel 11 so as to know the twisted angle of the solar panel 11 from the direction of the sun.

At this time, since the solar panel control unit 19 controls the driving motor 15 based on each value sensed by the plurality of solar sensors 17, the solar panel 11 is driven by the driving motor 15. By rotating in the direction of the sun.

In addition, the driving motor 15 preferably uses external power supplied from the external power input unit 50. Here, the external power may be a DC or AC power supplied from a home or an office.

At this time, the motor driving unit 19e drives the drive motor 15 by the motor driving unit 19e to correct the difference by a different value.

In addition, when the driving motor 15 is driven and no difference between the sensing values sensed by the plurality of solar sensors 17 occurs, the motor driving unit 19e stops driving the driving motor 15. Therefore, since the solar panel 11 is always adjusted to face the sun, it can easily absorb a large amount of sunlight.

In addition, the solar panel control unit 19 may be configured to include a control box (70).

And, as shown in FIG. 4, the boiler 40 uses a water tank 41, a pipe 42 for circulating water in the water tank 41, and a water tank (using a power source of the battery 30). 41 may be configured to include a heater 43 for heating the water filled in, and a pressure discharge trap 45 for discharging the pressure when the pressure of the water tank 41 is increased by a predetermined value or more.

Here, the heater 43 may directly heat water using a DC current, and since the DC current generated from the solar panel 11 is directly used, there is a convenient advantage. In this case, the heater 43 may heat water from 12V to 48V.

In addition, the water tank 41 is preferably filled with a medium height in consideration of the amount of water recovered. The pipe 42 is connected to a discharge port 41a through which water from the water tank 41 is discharged, and a discharge port 41b through which water discharged through the discharge port 41a is recovered to the water tank 41. Can be circulated. In addition, the water tank 41 is formed in the upper portion of the water tank 41, the inlet (41c) for replenishing water.

And, the heater 43 is preferably disposed from the top of the water tank 41 to the bottom in order to increase the area in contact with the water. That is, when the contact area of the heater 43 is increased, a large amount of water can be heated quickly. In addition, the pressure discharge trap 49 may discharge the pressure increased in the water tank 41 to the outside to prevent breakage and explosion of the water tank 41.

In addition, the pipe 42 may be further provided with a circulation pump 47 at the rear of the pipe 42 to facilitate the circulation of water. The pipe 42 may further include a hot water pipe 46 for supplying hot water by the control of the hot water valve 44. In addition, an auxiliary valve 48 for supplying and stopping hot water may be further provided between the pipe 42 and the hot water pipe 46.

It may be configured to include a pressure discharge hole (49e) formed in the pressure discharge pipe (49a).

First, the pressure discharge hole 49e formed higher than the weight support jaw 49d may be kept closed by the weight 49b supported by the weight support jaw 49d.

Here, when the pressure of the water tank 41 is increased by the heating of the heater 43, when the weight 49b rises along the pressure discharge pipe 49a by the increased pressure, the increased pressure causes the pressure discharge hole 49e to rise. Can be discharged to the outside. Then, when the elevated pressure is discharged and the pressure of the water tank 41 is lowered, the weight 49b is lowered and supported by the weight support jaw 49d. At this time, the weight of the weight (49b) can be adjusted to be produced so as to discharge more than the pressure that the water tank 41 can withstand.

The external charge switch 72 controls the switching unit 60 to charge the battery with external power supplied by the external power input unit 50 on a cloudy day or evening when sunlight is not absorbed.

In addition, the pressure sensing unit 73 and the temperature sensing unit 74 may be installed in the boiler 40. In this case, the sensed pressure and temperature values may be displayed by the pressure and temperature display unit 75. In addition, the pressure and temperature display unit 75 may be implemented as a liquid crystal plate. That is, the user may visually check the displayed pressure and temperature values and correspond to them.

In addition, since the current supplied from the battery 30 is controlled and supplied by the current controller 76, the boiler 40 may heat or lower the temperature of the water.

In addition, the charging state display unit 79 may be further provided to display the charging state of the battery 30. In this case, the charging state display unit 79 may be implemented as a lamp. That is, the user can visually check the state of charge by checking the lamp.

Here, the timer 78 stops the operation of the boiler operation switch 71 after the operation time is completed if the operation time of the boiler operation switch 71 in the state set the operating time. That is, since the user can drive the boiler 40 for a predetermined time, it is possible to save the power of the battery 30 by driving the boiler 40 unattended without the user.

In addition, the pressure and temperature values displayed on the pressure and temperature display unit 75 may be stored in the memory 90. In addition, the memory 90 may store the adjustment state of the angle adjuster 77. In addition, the set time of the timer 78 may be stored and provided to the boiler operation switch 71.
