Is it possible to do modeling for LDR(light dependent resistor) for a solar tracker?

Hello guys, I currently doing a solar tracker modeling in Simulink. I do dual axis solar tracker that is elevation angle and azimuth angle. At first, I will input the latitude and longitude to calculate the solar position. Then, the panel will rotate to the desired solar position. I try to use LDR as a feedback sensor to see whether that angle is the best angle to harvest solar energy. After getting feedback from the LDR,the angle will be adjust to reach it maximum solar energy harvesting. The question is how to do a modeling for LDR as a feedback sensor?

do you have a solution bro ?
