So im trying to figure out how much Wh I would have with these solar cells I have. Each solar cell is rated to have 2.8w. Does this mean if I have 40 of them I would have 112 wh? I am going to be putting the solar cells in series. Does this affect the power? I know adding in series is good because it boost your voltage but.. im not sure if that affects your power. If it does then, How do i figure out what my power would be?
