AC Driver for low voltage LED

LED newbie question here...

I have a solar-powered LED address plaque that doesn’t get enough sunlight to charge the Ni-MH battery.  So I’d like to replace the battery with a 110 VAC driver but I’m not sure which one.  The specs are:

SMD2835 3V 0.2W x 10 (I assume these are connected in parallel?)

Battery: 1.2V NiMH AA 1200 mAh 

(Solar panel: Poly-silicon 2V 300ma)

Any suggestions for an appropriate driver?
