最大出力点から著しくはずれた点Ｃに移る。In the figure, ■ is a solar cell plate, and when the solar panel (:) is irradiated, there is a positive pole at terminal 3 and a negative pole at terminal 4.
"tl), h is generated and the output is 5. ・L+l !+'j of the olfactory diagram 2, the 1st field of the pond panel 2 is re-extracted by the circuit shown in Figure 3 in the electromotive state. Here,
Items with the same numbers as in Figure 2 are i.
This solar panel 2 has a V value when the temperature is kept constant (e.g., SuOK) and the amount of solar radiation is changed. As shown in FIG. 4, the relational curve between the output current 1s and the output pressure &s changes as the amount of solar radiation changes, and changes like the three curves marked by the dotted line in the middle of the maximum output point Frd1<J. 9t and now there is solar radiation! 'l
For example, when the solar radiation amount changes from 50 to 100 due to changes in the weather, for example, when driving with a resistor that can obtain the maximum output when O+Ni is 4 and connected to the solar panel 2, the amount of solar radiation may vary from 50 to 100. When the amount of solar radiation increases to 1I, the operating point is determined from the intersection point A of the load characteristic curve with the relational curve of output current versus output CD pressure when solar radiation is 50, and the operating point is 100 + nV'J when solar radiation is 50.
It moves to the intersection point 13 with the output current vs. output voltage relationship curve when /ctA, and it is no longer possible to output the maximum output by one. Also, from 150 trWArl of solar radiation, for example, 1
0IIA%'/2! , the operating point moves to point C, which is significantly away from its maximum output point.

することが難しくなる。As described above, the output of a solar panel group constructed by connecting a plurality of solar panels 2 in series and parallel, whose output fluctuates as the amount of solar radiation changes, is also easily affected by the amount of solar radiation. Therefore, it is not possible to efficiently extract output from the solar panel group up to this trench, resulting in a low efficiency solar power generation system. Usually, as a load, if it is a DC device, it requires constant voltage characteristics, or if it is an AC device, it is necessary to convert DC to AC, so as shown in Fig. A converter 13 consisting of a chopper or an inverter at the output of
f shows the system connected to the load 14 via f. In FIG. 5, 11 is a solar cell panel group consisting of a plurality of solar cell panels 2, and 12 is a backflow prevention diode. In order to prevent the aforementioned low efficiency of the solar power generation system, conventionally the solar power generator 11
There is a method in which a monitor circuit for monitoring the electromotive force of the solar power generator 11 is provided close to the solar power generator 11, and the converter 13 is controlled so as to extract the maximum electromotive force of the solar power generator 11 using the output of this monitor circuit. It is considered. As shown in Fig. M6, this monitor circuit was configured with a solar cell panel 2 or a device capable of measuring sunlight irradiation, in addition to the solar power generator 11. However, the configuration shown in Figure 6 is the solar power generator 11.
It is not possible to monitor the true emf of For example, in the figure, if the solar power generation (C) 11 is blocked by clouds etc. and the monitor circuit 21 is receiving solar radiation, the output of the monitor circuit 21 will limit the electromotive force of the solar power generator 1. Since the converter 13 is controlled in such a manner as described above, there arises a drawback that control is performed that significantly deviates from the operating point shown in the explanation of FIG. The larger the scale of the solar power generator 11, the more likely this drawback will occur, and the more difficult it will be to control it.

This was done in order to provide a solar power generation device that can always produce maximum output so that the operating point of the solar power generator does not shift.

動作点のずれが発生することを防止できる。(e) Effect of the invention Therefore, since the monitor solar cell 34 is installed in the solar cell panel group 31, the solar cell 34 is installed in the solar panel group 31.
This means that the solar panel receives solar radiation equal to the solar radiation of one or both of the solar cell panels 2 constituting the solar cell panel 1. That is, if one side of the solar panel 2 is blocked from sunlight by clouds or the like, part of the monitor solar cell 34 will also be blocked from sunlight, and the solar cell panel with two solar panels 2 connected in series. At the same time as the output of the group 31 decreases, the output 343 of the monitoring solar cell 34 also decreases. Father, even at this time, if the solar panel group 32 is free from interference with solar radiation from the back etc., the output of the solar panel group 32 can be equivalent to the amount of solar radiation, and the monitoring solar The output 353 of the pond 35 can also provide an output sound proportional to the output of the solar panel group 32. The same is shown for solar panel group J3. This monitor solar cell 34°3
The outputs 343, 353, and 363 of 5.36 are added to the converter 1 using a commonly known adder (not shown).
3, the solar panel group 32 receiving solar radiation
゜3: Maximum electromotive force can be extracted from the tube. In addition, if the outputs 343, 353, and 363 are connected in series, interference with solar radiation from the solar panel group 31 will reduce the monitor output and suppress the output of the converter 13. In other words, the monitoring solar pond installed inside the solar battery panel 11 is used to monitor the output power of the surrounding solar panels, as shown in Figure 6. It is possible to prevent deviations in the operating point from occurring due to differences in sunlight irradiation, as in the conventional case.
