I was commenting on an oft heard comment that trackers aren't worth it - they "expend more energy than they save"...!!
I did a rough calc and reckoned about a 10 or 20:1 payback (energy-wise) based on an adjustment at a max of 3 degrees (which corresponds to about a 5% drop in output).
So I couldn't understand the naysayers.
Then I spoke to a few, and they all started "(Well you stoopid idiot...) the CPUs....".
And they reckoned I was stupid?
(Then I explained why digital computers are so inferior to analog.... LOL!)
BTW - the connection to this thread was the talk of in-house batteries, CPUs etc....
