How will it take to charge 36V 4Ah battery using a 5V 2.4A Solar Panel?
Now, 42W at 5V 2.4A doesn''t make any sense (5V and 2.4Ah makes less sense for a solar panel). So I''d guess it was actually 5V * 2.4A = 12W. 144Wh / 12W = 12h of charging considering 100% efficiency, etc. If you consider 80% efficiency for the charger*, then 12h/0.8 = 15h of full output from the solar panel. So maybe two days for 12W solar panel?
