hi, i need help i want to charge my mobile phone from the solar cell which gives me 5V in a sunny day
this circuit still gives me the same input( output=input)
i want to change it in order to step up the voltage.
because i want to charge my phone indoor also using the solar panel
That's not the actual power output if you just multiply short circuit current and the open circuit voltage. It has to be measured simultaneously to get the real power available.
