Not really a question for a programming site but as it's in my area. You configure the LM317T as a current source you can neglect the voltage totally. There is a formula for trickle charge rate of NiMh an online calculator is here Rechargeable battery charging time and mA current calculator | Convert to units and culinary measures.[^]

For a 2000maH stack maximum trickle charge rate is 66mA which is well within range of your solar panels. You can't charge any faster using a simple LM317T circuit otherwise you will damage the batteries.

Finally the circuit is shown here (second one with the solar panels)
Ni-Cad Battery Charger with LM317 - Jose Pino's Projects and Tidbits.[^]

The 22 Ohms on the circuit will give you 56mA of trickle charge .. if you want exact max 66mA you need 19 Ohm 1/2 Watt resistor.

The diode protect (1N4001) protects the solar panels when they aren't in sunlight

You want a more advanced charger go to a proper electronics hobby site and not here Smile | :)
