The solar panel is most efficient at a point called the maximum power point which is surprisingly not the maximum voltage 10v but a little less 8v.
The sunny buddy s output charge current measured was about 7ma since the small 2w solar panel was not able to reach the minimum input voltage requirements by itself.
We recommend using a larger solar panel like the 3 5w 6w or 9w solar panels to achieve the sunny buddy s minimum voltage input requirements.
Set up is easy as well just plug your solar panel into one side of the sunny buddy and your battery into the other and you are good to start charging.
