It should be even easier to store Oxygen.

It can be stored as either water (H2O) or hydrogen peroxide (H2O2) without refirgeration.

Water can be electrolyzed as needed, this would need somewhat larger solar panels.

Peroxide can be catalytically decomposed so would not need extra solar panels. It also has a higher Ox mass fraction, so has some advantages over water. Of course H2O2 decomposition leaves water as a by-product, this could be electrolyzed. If we do this, we get twice as much oxygen per watt by storing it as H2O2 rather than as H2O.

Another benefit, H2O2 when decomposed actually creates energy, so it could possibly be used as a power source,
driving a turbine for power, then collecting the exhaust to use as propellant.

All that is bit complex, but probably less complex and lighter than rerigeration.
