Reg: Circuit to charge the capacitor from solar cell?

We Answered:

It doesn't matter how many micro-farads the capacitor has, apparently the time it takes to charge the cap is not so important to you....
The "circuit" is like that:
Connect the "plus" of the solar panel; to the anode of a universal diode, like 1N4001
Connect the Cathode of that diode to the "plus" of the capacitor.
Connect the "minus" of the solar panel to the "minus" of the capacitor.
Finished.
Since the diode will "steal" about 0.7 volt, your solar cell should be a 4.5 Volt type.
