The control method for the self-diagnosis for the solar cell module 128 is as shown in FIG. 6, and the control method for the self-diagnosis for the wind generator 131 is as shown in FIG. 7.

First, referring to FIG. 6, the controller 139 operates the solar radiation sensor cleaner 166 to clean the incident surface 160 of the solar radiation sensor 159 (S10), and then the sun through the solar radiation sensor 159. The solar radiation amount irradiated to the battery module 128 is measured (S11). If foreign matter such as dust is deposited on the incident surface 160 of the solar radiation sensor 159, accurate solar radiation information cannot be obtained. Therefore, the incident surface 160 may be cleaned before the solar radiation sensor 159 operates.

Subsequently, the controller 139 measures the amount of electricity generated by the solar cell module 128 through the power meter 164 (S12), and the measured amount of power Pm1 and the solar radiation sensor 159 are measured. The initial set power amount Ps1 of the solar cell module 128 according to the solar radiation amount is compared (S13). Here, the initial set power amount Ps1 of the solar cell module 128 is an amount of power produced by the solar cell module 128 in a normal state, and a value according to the amount of solar radiation is preset and stored in the controller 139. .

The controller 139 determines whether a difference value between the initial set power amount Ps1 and the measured power amount Pm1 exceeds 15% of the initial set power amount Ps1 (S14), and if it is within the allowable range, the solar cell module ( It is determined that there is no problem in the operation of 128). On the other hand, when the difference value exceeds 15% of the initial set power amount Ps1, the control device 139 determines that there is a problem in the operation of the solar cell module 128, generates an abnormal signal, and generates a wireless communication device 137. The control room is notified through (S15) and the solar cell module cleaner 140 is operated to clean the incident surface 129 of the solar cell module 128 (S16).

Next, a control method for self-diagnosis for the wind generator 131 will be described with reference to FIG. 7.

The controller 139 measures the wind speed of the wind for operating the wind generator 131 through the wind speed sensor 162 (S20). In addition, the control device 139 may collect information on the direction of the wind through the wind direction sensor 161 and reflect it on the information obtained from the wind speed sensor 162. Subsequently, the controller 139 measures the amount of electricity generated by the wind generator 131 through the amount of electricity meter 164 (S21), and measures the measured amount of electricity Pm2 and the wind speed measured by the wind speed sensor 162. Compare the initial set power amount Ps2 of the wind power generator 131 according to (S22). Here, the initial set power amount Ps2 of the wind power generator 131 is an amount of power produced by the wind power generator 131 in a normal state according to the wind speed, and is set in advance and stored in the controller 139.

The controller 139 determines whether the difference between the initial set power amount Ps2 and the measured power amount Pm2 exceeds 10% of the initial set power amount Ps2 (S23), and if the wind turbine generator 131 is within the allowable range. It is judged that there is no problem in the operation. On the other hand, if the difference value exceeds 10% of the initial set power amount Ps2, the control device 139 determines that there is a problem in the operation of the wind generator 131 generates an abnormal signal and the wireless communication device 137 By notifying the control room through (S24) to be managed by the manager.

In the present invention, the allowable range for determining the abnormality of the solar cell module 128 is not limited to 15% of the initial set power amount Ps1 as described above, and may be variously set according to various conditions. In addition, the allowable range for determining the abnormality of the wind generator 131 does not need to be limited to 10% of the initial set power amount Ps2 as described above, and may be variously set according to various conditions.

On the other hand, Figure 8 shows a part of the water purification apparatus according to another embodiment of the present invention.

The water purification apparatus according to another embodiment of the present invention is a solar cell module 180 and a portion of the configuration is changed, the rest of the configuration is the same as the water purification apparatus 100 described above. In the solar cell module 180 according to another embodiment of the present invention, its tilt may be changed by the tilting mechanisms 183 and 189.

The first tilting mechanism 183 adjusts the left and right tilts of the solar cell module 180, and the second tilting mechanism 189 adjusts the vertical tilt of the solar cell module 128. The first tilting mechanism 183 includes a tilting frame 184 and a tilting frame 184 which are rotatably coupled to a pair of brackets 186 fixed to the base panel 111 (see FIG. 1). 185). One end of the solar cell module 180 is rotatably coupled to the tilting frame 184 in a vertical direction by the hinge device 187.

The second tilting mechanism 189 includes a pair of guide members 190 provided with the tilting frame 184 and a pusher 192 coupled to the tilting frame 184 to push the solar cell module 180. The guide member 190 is provided with a guide groove 191 having a predetermined curvature, and the protrusion 182 of the solar cell module 180 is inserted into the guide groove 191. When the operation arm 193 of the pusher 192 pushes the solar cell module 180 upward, the protrusion 182 moves along the guide groove 191, and the inclination of the solar electric module 180 increases, and the pusher 192 When the operation arm 193 of) decreases, the solar cell module 180 inclines in a direction in which the inclination decreases due to its own weight.

These tilting mechanisms 183 and 189 may be controlled by the controller 139 so that the solar cell module 180 may tilt in accordance with the sun. For example, the control device 139 may control the tilting mechanisms 183 and 189 according to the solar radiation information detected by the solar radiation sensor 159. The structures of the tilting mechanisms 183 and 189 are not limited to those shown, and may be changed to various structures capable of varying the inclination of the solar cell module 180.

The solar cell module cleaner 140 for cleaning the incident surface 181 of the solar cell module 180 is the same as described above. However, the solar cell module cleaner 140 is coupled to the solar cell module 180 to maintain the wiper 141 in contact with the incident surface 181 of the solar cell module 180. The drive shaft 149 and the driven shaft 151 are rotatably coupled to the support members 195 and 196 coupled to both ends of the solar cell module 180, respectively.

In addition, the solar radiation sensor 159 and the solar radiation sensor cleaner 166 is coupled to the support plate 198 coupled to the solar cell module 180 so as to be tilted together with the solar cell module 180. Therefore, even when the solar cell module 180 is inclined, the incident surface 160 of the solar radiation sensor 159 is always inclined in the same direction as the incident surface 181 of the solar cell module 180.

In the solar cell module 180 according to another embodiment, the power productivity is improved by tilting the incidence surface 181 at the tilting mechanism 183 and 189 at an angle that receives the most sunlight.
