I have mentioned this before and will again:
Why not construct clusters of low voltage batteries each with their own
set of solar cells. Then each low voltage battery ( 3 volts or so) has
its own boost voltage converter to charge to a much higher voltage bus
(15-24 volts). In this way, the failure or depletion of a battery will
affect only the available current on the bus, not the voltage.
The solar cells could then be placed on all sides of the spacecraft and
charge their associated batteries at will, with no concern of having the
entire solar cell array in same plane with the sun as there would be
with a high voltage string of solar cells.
