Herb is right, there is no free lunch. If you double the output voltage you at least double the input current, so you need fewer cells but they each need bigger capacity. You do have more flexibility on the voltage supplied though.

However there is another advantage. If you have a big single cell it is easy to charge. If you have two smaller cells you need to provide for balance charging of the two cells which is slightly more complicated. This can make the installation easier.
