Hello every one I have a question that I hope has not been asked recently.
Because solar cells are limited by the amount of sunlight they see there output fluctuates.
Is it possible to design a circuit that will keep the output at a constant voltage with out adding a lot of other parts?
What I would like to do is to make a circuit to add to a typical solar cell powered garden light that uses a single 1.2 volt rechargeable battery.
On a Clear day I have observed that most of the solar cells I have will put out 2 to 3 volts without a battery to charge.
But as expected when it clouds up the voltage will drop down to under 1 volt which will not fully charge the battery and the led will not stay on all night.
Is there a way to make the voltage a constant 2 to 3 volts as long as there is some sun light?
Thanks in advance
