Yes - I'd keep the 9v regulator, since I need the range.

At the moment that's the approach I'm using. I have a 20w solar panel, but last Winter I noticed a big drop off in power produced. The problem is that I'm finding all sorts of other, non-weather related things that I'd like to run off the 12v supply in that area of the garden now and that leaves less power budget for the Tx. Maybe I'll have to buy a 30w panel next Winter.
