20% was a number I pulled out of the air based on some things I've heard. I don't know that I'll ever be able to measure the true difference. These batteries just sit there on float 95% of the time and I have no device for measuring my amps in/out on this little system.
I'm preparing to fly a 680 watt array with a similar setup. It might be possible in a year or so for me to compare fixed vs. tracked on the bigger system but it won't be for quite a while.
I haven't thought much about heat in the jar. Hmmm, maybe I should. The nice thing is if I burn the tracker up, it's only a $35 lesson.
I was out yesterday and today and the thing was pointed exactly at the sun every time I looked at it. It works flawlessly so far. Maybe I'll disable it for a while since I'm not using a single watt of that electricity I'm making.
Now I'm dreaming on how I could use the heat from a solar concentrator. I've got two very nice eight foot aluminum dishes laying around here.
