What is the optimum charging voltage for 1.2 volt ni-cad rechargeable AA batteries?

I am going to build a solar panel that charges these batteries so i I need to know the best voltage to charge them.

I generally charge nimh at about 1.5v nicads are about the same. To get them to full charge it needs to be higher than 1.4v since the actually fully charge voltage of a nicd cell is 1.4v ish 1.2v is the nominal capacity that they drop to under load.

You need more than 1.2V, but not that much more. What does the panel give you?

What's their capacity ? Charge ni-cads by current. "nice " charging would be at a rate of capacity / 10
