This isn't what you're asking for, but when I heard the word "lake", are you allowed a floating dock? Or better yet, a floating swim platform that would be out there in the sun just begging for a few solar panels? There's a fellow in BC who's put in enough floating gardens to get some serious food out of it (too little sun and too many rocks on shore for a garden) and there's evidence that floating food gardens can actually improve water quality, so I'm just throwing the idea out there.
At least you've thought about the option. There are pros and cons to every location, and we all work within what our land supports. I know *all* about big trees blocking my light!
However, I have actually thought about floating dock solar panels but the run would require cables thick as your arm. Likewise, I could put them on the embankment and get longer direct sun but we're still talking a 60 foot run.

10A Cable/Wire $40 (at 120V-DC the cable actually doesn't need to be thick for a 60ft run, no different from a regular 60ft 120V-AC extension cord)
100A Charge Controller $500 (it's very likely that you can continue using your current charge controller, battery bank, wires, inverter, etc)

Seeing as how you are only using 1KWH out of 1gallon of gasoline, that strike me as a very inefficient system. Even then it still use less fossil fuel per day than most folks, so its still a win.
