The importance of solar energy is increasing in Gujarat. Now, large solar plants have started to be built to generate electricity from solar energy.
However, a technique to know whether a solar panel is working properly or not once installed has been developed by IRDA (Electrical Research and Development Association) and researchers from MS University’s Faculty of Technology.
Further, “Solar panel efficiency can be tested in the laboratory, but they don’t yet have the technique to know which panels are working properly on site where the panels are installed”. Thermography cameras and IV tracers are used as part of this technique. According to them, a number of panels are connected to one solar panel and if there is a defect in one panel, it affects the other panels.
Furthermore, it reduces the production capacity. For this, it is necessary to check the efficiency of solar panels. They have started using this technology. Through it, they have checked and found defective solar panels in four to five solar plants.
How is a faulty panel detected?
On the other side, a hot spot is detected on the solar panel with a thermography camera. The normal temperature of the panel is around 50 degrees, but if a hot spot is seen, it can be estimated that, the panel is not working properly. If there is a hot spot, a certain type of color is visible on the camera.
After, its temperature is measured with such a tracer. If the temperature is 25 to 30 degrees higher than the normal temperature, then it can be assumed that, the solar panel is not able to generate electricity properly. Most of the time, such panels are replaced.
Awarded the best research paper in an international conference
A research paper on the technique of knowing the efficiency of solar panels was recently presented in the Faculty of Technology in an international conference on Researched Advances in Applied Science and Engineering. This paper also won the best paper award in the conference.
