How to stop PWM signal?

hi. using servo move rather heavy solar panel. once set angle to, say, 45 degree, servo doesn't quite has strength move panel 45 degree , motor rotating, trying panel 45 degree.

my question is, possible turn off pwm signal once set angle 45 degree? if not, can using external circuit? (using nmos or whatever?)

code: [select]


#include <servo.h>

setup(){
servo myservo;
myservo.attach(3, 300, 1550);
}

loop(){
myservo.write(45);
delay(2000)
}


if stop servo refresh won't hold position.
if that's not issue can "detach" pin.
