make solar panel/ paneles solares caseros

To make different proyects, I need energy that is not available all time in the village. for this reason, I experimented with the construction of a solar panel. 

I used tedlar, solar cells, glass, heat gun and very patience. the sandwich is compound glass, tedlar, cells,tedlar and glass.

the mounting of solar system is show in this picture:

finally the system of 24 volts I get [3.5-4.0] Amp as max power.

Solar Tracker./ mini seguidor solar

The objetive of this proyect is make a solar tracker to use it in a future solar oven or solar panel proyect.

code:

       

#include //desactiva pwm 9 y 10  arduino uno
Servo miservito1;
float ldr1;
float ldr2;
int pinTemp1=1;
int pinTemp2=5;
int pote=0;
int delta=5;
int pinservo1=2;

void setup() {
 miservito1.attach(pinservo1);
 Serial.begin(115200);
 pinMode(11, OUTPUT);
 pinMode(12, OUTPUT);
 pinMode(13, OUTPUT);
}
 
void loop() {
 ldr1=analogRead(pinTemp1);
 int potenciometro=analogRead(pote);
 potenciometro=map(potenciometro,0, 1023, -40, 40);
 Serial.println(ldr1);
 ldr2=analogRead(pinTemp2)+potenciometro;
 Serial.print(" ");
 Serial.print(ldr2);
 Serial.print(" ");

//Serial.println(potenciometro);
 float tol=ldr1-ldr2;
  
  if (tol > delta){
  digitalWrite(11, HIGH);
  digitalWrite(12, LOW);
  digitalWrite(13, LOW);
  miservito1.write(93.0);
  }
  if (tol <= delta && tol >= -delta){
  digitalWrite(11, LOW);
  digitalWrite(12, HIGH);
  digitalWrite(13, LOW);
    miservito1.write(90);
  }
  if (tol < -delta){
  digitalWrite(11, LOW);
  digitalWrite(12, LOW);
  digitalWrite(13, HIGH);
    miservito1.write(86);
  }
delay(250);
}
