That's not at all how battery charging works.
Whatever the voltage output of the solar panel is, you can always step that up or down.
The batteries go up in voltage slightly when they are charging, but not much relatively.
For a typical LiIon cell, it may be at "0%" at 3.4V (you don't want to drain it all the way). And "100%" full is around 4.2V.
As long as you can supply at least 4.2V, it will charge up to that point.
