Solar battery charger with overcharge protection

This circuit is formed maintain one’s position voltage from solar cell with , shunt regulator circuit. For protect voltage not too until much destroy battery. Because of something charger too much. The D2 be for protect current flow turn back from battery during nighttime. The circuit maintains one’s position current the few , for feed give the circuit randoms voltage battery. Which have IC LM723 be main part by may use battery model acid general lead. That want power supply give the circuit all the time , thus should choose battery at have many capacity such as , 40Ah sizes etc. The detail is other , see in the circuit.

Analog Solar Tracker by power Mosfet IRFZ34 + LM339

The basic operation is essentially that of 2 separate photo sensor circuits in pairs. Each separate sensor circuit has a control pot to set it’s sensitivity for bright sunlight.

It is important to have a thorough understanding of the operation of the circuit in order to be successful in making the correct adjustments for acceptable operation. One must do the adjustments on a clear cloudless day. At the very least wait until the sun is between clouds.

CdS cells have a wide variance in the resistance they exhibit in bright sunlight. Generally the resistance is too low for this type of circuit. I have found that the CdS cells can be modified to have higher resistance by painting the cells with a black marker. I use a Sharpie black permanent marker. I paint this on all sides and edges. If you get too much on it can be removed with fingernail polish remover or acetone.
