I'm need to calculate the how long it will take to charge a battery using a solar cell. I am not taking any charge curves into account, I just want to get a close answer before I run the experiment. I have attached the battery specs as well as the solar specs. I tend to get lost as I go down the rabbit hole with the calcs. Could someone please help.
My Battery calcs:
1600mAh / 13.44W *4.2v = 5hrs (im not sure if this is even close)
My solar calcs: wh=(mAh)(v)/1000 1600mAh*4.2/1000=6.72wh 6.72wh/0.000198W = ?
I am not an EE and I feel like im all over the place. Thoughts?
