[Elecraft] slightly OT: need reference for solar charging system for 18AH battery

[Allan Taylor]

I know someone who checks this reflector is heavily involved in solar
charging for small (QRP) station use. I have
a fresh 18 Ah battery that I wish to take along to power the K2 on a
white water raft trip (Salmon River, Middle Fork).
This has proven an impetus to finally inquire about a solar charging
system. Can someone point me to this
person (or others) to get me off dead center??
