Problems solved by technology

[0003] Due to the permanence, cleanliness and flexibility of solar cells, products using solar power generation technology such as solar water heaters, solar street lights, and solar batteries are very common at present. However, the solar panels of these products generally can only receive radiation from a fixed direction The sun's rays, and in fact the angle of the sun's radiation will continue to change over time, so these products have a low utilization rate of solar energy

Embodiment 1

[0063] see figure 1 , figure 1 It is a schematic flowchart of a method for controlling the rotation of a solar cell panel disclosed in an embodiment of the present invention. in, figure 1 The described method for controlling the rotation of a solar panel is applicable to a control device for a solar panel. like figure 1 As shown, the method for controlling the rotation of solar panels may include the following steps:

[0064] 101. The control device judges whether the current time is the preset collection time, if yes, execute step 102, and if not, end the process.

[0065] In the embodiment of the present invention, since the sun moves relatively slowly, the control device can determine whether to control the rotation of the solar panel according to a certain frequency, and the frequency can be set according to the rotation speed of the sun. Specifically, the control device can set the sunrise time and sunset time of the day as the start time and end time of a collection...

Embodiment 2

[0081] see image 3 , image 3 It is another method for controlling the rotation of solar panels disclosed in the embodiments of the present invention. like image 3 As shown, the method for controlling the rotation of solar panels may include the following steps:

[0082] 201. The control device judges whether the current time is a preset collection time, if yes, directly execute step 203, and if not, execute step 202.

[0083] 202. The control device judges whether the real-time output power of the solar panel is smaller than a preset first threshold, if yes, execute step 203, and if no, end the process.

[0084] In the embodiment of the present invention, the first threshold is set with reference to the average output power of the solar panel at the current moment when the conversion data of each voltage value in each voltage value group is equal. The real-time output power of a solar panel can characterize the ability of the solar panel to convert solar energy into ele...

Embodiment 3

[0102] see Figure 4 , Figure 4 It is another method for controlling the rotation of solar panels disclosed in the embodiments of the present invention. like Figure 4 As shown, the method for controlling the rotation of solar panels may include the following steps:

[0103] 301. The control device receives a target time sent by any mobile terminal through a Bluetooth connection, and sets the target time as a preset collection time.

[0104] In the embodiment of the present invention, the control device may include a bluetooth communication module, which is used to perform data transmission with an associated mobile device through a bluetooth connection. According to different scene requirements, users can customize different collection moments.

[0105] In this embodiment of the present invention, steps 302 to 305 are the same as steps 201 to 204 in Embodiment 2, and the following content will not be repeated.

[0106] 306. The control device judges whether the conversi...

Abstract

The invention provides a method and a device for controlling rotating of a solar cell panel. The method comprises steps of determining whether the current time is preset collection time, if yes, obtaining voltage value groups collected by at least one pair of photosensitive sensing modules symmetrically arranged on the solar cell panel, and each pair of the photosensitive sensing modules is corresponding to one voltage value group, and each voltage value group is composed of a voltage value collected by each photosensitive sensing module in the corresponding pair of photosensitive sensing modules; performing analog-to-digital conversion operation on the voltage value included in each voltage value group to obtain conversion data for each voltage value in each voltage value group; and controlling rotation of the solar cell panel according to the conversion data of each voltage value included in each voltage value group until that the conversion data for each voltage value in each voltage value group is the same. The embodiments of the present invention can improve the utilization of solar energy.

Description

technical field [0001] The invention relates to the technical field of solar cells, in particular to a method and device for controlling the rotation of a solar cell panel. Background technique [0002] A solar power generation system is a power generation system that can directly convert light energy into electrical energy through the photovoltaic effect. Solar panels are the core part of the solar power generation system and also the most valuable part of the solar power generation system. Its function is to convert the solar energy into electrical energy, and then store it in the battery, or use it to drive loads to work. When the sun shines on the photodiode of the solar panel, the photodiode will convert the sun's light energy into electrical energy, generate current, and complete the conversion of solar energy into electrical energy. [0003] Due to the permanence, cleanliness and flexibility of solar cells, products using solar power generation technology such as so...
