What are the modifications that we can do to improve the performance of the solar and wid plant? Explain with diagrams. How it will improve the performance for both
Some of the Factors or modifications that can help in improving the performance of the solar plant are:
1. Solar cell glazing
To increase the life cycle of the solar panel it is needed to protect the surface of the solar panel and for that, we can cover the surface with polycarbonate or low-iron glass. It is recommended to use this material because its transmissivity is nearly 90%. This is material can be used for the replacement of the glass on the solar panel since glass transmissivity is less as compared to the polycarbonate. Consider the diagram shown below for the glazed flat plate solar panel.
2. Solar panel orientation
the output of the solar panel is directly dependent on the angle at which solar rays fall on the surface of the panel. For the maximum output, the rays should fall perpendicular to the surface of the panel. For this purpose solar tracker is used. The solar tracker changes the orientation of the solar panel throughout the day. It makes sure that the panel surface is always facing the sun directly. Consider the diagram shown below,
3. Solar concentrator
The output of a solar panel is directly proportional to the intensity of the light falling on it. So to optimize the output a solar concentrator can be used to increase the intensity of the light falling on the panel.
