Portable solar charger designed using LM358N

This portable solar charger circuit electronic project is designed using some common electronic parts .
As you can see portable solar charger circuit, is based on a LM358N operational amplifier and one transistor.

This regulator provide a constant 2.4 volts DC and can be used for powering small devices that needs to be powered from two AA battery cells .
Because the regulator has a low drop down voltage of 0.3 volt you should take care about this when you choose solar cells .
Maximum load current for this solar charger electronic circuit project is around 125mA typically , enough for small portable devices like radios .

Hello This YOUR Application has a FATAL ERROR! The PIN 1 must be changed to PIN 8 of IC LM358!!! In YOUR Application - so cannot functionally! Thanks

From datasheet of LM358 pin 8 is VCC Pin 4 is GND and pin 1 is Out A.
