Background technique

Solar energy is the most environmentally friendly and clean energy source, and the use of solar energy to generate electricity is becoming more and more popular. However, there is still a lot of room for improvement in the efficiency of its power generation. The installation locations of solar panels today are all installed in order to obtain a large amount of sunlight. On the top floor of the building, the installation site is not only high but also dangerous, so there are few inspections. When the solar panels are installed, in order to prevent the dust and dirt on the panel area from affecting the power generation efficiency, the solar panels are all installed in an inclined shape, and the power generation of the solar panels It is not large, so a large number of solar panels must be installed in series. The power generation efficiency depends on whether the solar panels are clean. If there is one solar panel of poor quality or dirty (such as bird droppings) in the whole string of solar panels, it will seriously affect the entire string of solar energy. It is difficult to detect damage or poor quality among many solar panels. For this reason, the industry installs detectors for each solar panel, and then connects each detector to the control room for monitoring; but this is expensive. , and the junction box behind the solar panel will be damaged or the adhesion will be reduced during the construction process, which will affect the service life of the solar panel. the

Detailed ways

In order to make the features and advantages of the utility model more obvious and easy to understand, the content of the utility model and the functional benefits that can be achieved are introduced in detail below with illustrations, as follows:

Please refer to Fig. 1, the utility model relates to a solar panel performance detection device, the detection device includes a voltage detector 10 and a detection controller 20, the voltage detector 10 includes a voltage detection circuit 11 and a wireless transmission circuit 12. The voltage detection circuit 11 is connected in parallel to the power output terminal of the solar panel 30, detects the output voltage generated by the solar panel 30 at any time, and transmits the measured voltage signal through the wireless transmission circuit 12 at any time; and the detection control The device 20 contains a detection control circuit 21 and a wireless receiving circuit 22. When the signal emitted by the wireless transmitting circuit 12 of the voltage detector 10 is received by the wireless receiving circuit 22, it is checked and compared by the detection control circuit 21 to determine the signal. Whether the power generation efficiency of the solar panel 30 is normal. the

Please continue to refer to the voltage detection circuit 11 of the voltage detector 10 shown in Fig. 2 and Fig. 3, which is connected in parallel to the power output terminal of the solar panel 30, detects the output voltage generated by the solar panel 30 at any time, and the measured voltage The large and small signals are emitted by the wireless transmitting circuit 12, and the voltage detector 10 is installed in the junction box 31 behind the solar panel 30, so as to maintain the tightness without damaging the junction box. the

The solar panels 30 are arranged in series (as shown in FIG. 4 ), and a voltage detector 10 is installed in the junction box 31 behind each solar panel 30, and each voltage detector 10 detects the output generated by the solar panel 30 at any time. The voltage signal is transmitted by the wireless transmitting circuit 12, and is received by the detection controller 20 wireless receiving circuit 22, and the detection control circuit 21 is checked and compared (as shown in Figure 5); the power generation efficiency of the solar panel 30, It is related to the amount of sunlight and whether the solar panels are clean, but the amount of sunlight of each solar panel 30 should be consistent, so the detected voltage signal of each voltage detector 10 received by the wireless receiving circuit 22 of the detection controller 20 is determined by the detection. The control circuit 21 checks and compares. Under normal circumstances, the voltage signals detected by each voltage detector 10 should be the same (or within the normal error value). Due to the influence of climate factors, the power generation efficiency of each solar panel 30 should be the same. If the voltage signal detected by one of the voltage detectors 10 is lower than the voltage value detected by other voltage detectors 10, it means that the panel of the solar panel 30 may be dirty and affect the amount of sunlight on the solar panel 30, or the solar panel 30 may be dirty. The panel 30 may be faulty. After the detection controller 20 detects and controls the circuit 21 to check and compare, the abnormal solar panel 30 can be cleaned or repaired immediately. the

To sum up, the utility model solar panel performance detection device uses the voltage detector 10 to detect the output voltage of the solar panel 30, and the detection controller 20 judges whether the power generation performance of the solar panel 30 is normal. The essentials of the establishment of the patent have not been made public before the application. I sincerely hope that the Jun Bureau will clearly observe and grant the patent. It is really a prayer of gratitude. the
