方式とが知られている。(Conventional technology) Traditionally, solar power generation systems have two methods: a tracking method that changes the orientation of solar cells to follow the movement of the sun, and a method that installs solar cells facing due south at an angle of inclination that matches the latitude. It has been known.

なる傾向がある。(Problem to be solved by the invention) By the way, in the method of installing solar cells facing due south at an angle of inclination that matches the latitude, the amount of solar radiation on a clear day is highest at noon and lower in the morning and evening, so the power generation of the solar cells is difficult. As shown in FIG. 5, the electric power exhibits a parabolic generated power waveform 1 with reference to sunrise and sunset. However, on the other hand, in the case of a consumer such as a household, the load power 2 is often almost constant during the day, and the power used tends to increase in the morning and evening.

By synthesizing the waveforms, a composite generated power of the solar cells that approximates the load power is obtained.

きる。According to the solar power generation system according to claim 2 of the present invention, one solar cell is oriented in the direction in which the sun rises, and the other solar cell is oriented in the direction in which the sun sets, so that power is generated in the morning. It is possible to obtain the generated power waveform where the power is maximum and the generated power waveform where the generated power is maximum in the afternoon, and by combining these generated power waveforms, it is possible to generate power in the morning and evening instead of suppressing the generated power during the day. Electric power can be increased, and the power generated by the solar cells can be used effectively.

波形１１が得られる。In FIG. 1, 3 is the sun, 4 is a solar cell oriented due east, which is the direction in which the sun 3 rises, and 5 is a solar cell oriented due west, which is the direction in which the sun 3 sets. solar cell 4.5
is installed at an appropriate inclination angle θ depending on the location where the solar cell 4.5 is installed. The solar cell 4.5 is connected to a commercial AC system via an AC/DC inverter 6. As shown in FIG. 2, the generated power waveform 7 of the solar cell 4 has a waveform having a peak 8 in the morning, and has a characteristic that the waveform rises sharply in the morning and slopes gently toward the evening. As shown in FIG. 3, the generated power waveform 9 of the solar cell 5 has a peak 10 in the afternoon, and has characteristics that it rises gently from morning to daytime, and has a large fall in the evening. Therefore, by combining generated power waveform 7 and generated power waveform 9, instead of suppressing the wasted generated power during the daytime as shown by diagonal lines in Fig. 4, it is suppressed in the morning as shown by diagonal lines B and C. An increase in the generated power can be expected in the evening, and a composite generated power waveform 11 that approximately approximates the load power 2 can be obtained.
