want to operate the Arduino from your solar cell and do not propose any storage options, and if the cell generates about 8V open-circuit, then in this particular case, you operate it with a shunt regulator - which is to say, you simply put a 5.1V Zener diode of about 5W rating (given that the solar cells are guaranteed
to generate more than 5W) in parallel across the solar cell and feed this directly to
That is the simpler way of operating solar cells.
Note that you may have to calibrate the brownout threshold of the Arduino to cope with a
applied (and removed) supply voltage.
