That is a BRILLIANT installation. Hard to believe it is DIY.

Michael, you obviously know your stuff and have thought through this project way more than I ever could. You make me doubt my conclusions about one axis tilting to match the sun's inclination.

I used pvwatts to estimate how close a manual tilt 4 times a year would come to daily continuous, and IIRC I thought > 90% of ideal collection would be achieved with manual. What do your numbers and calcs say ?

I am unhappily surprised to hear the price you paid. I thought panels were under $1/watt these days; from your post it sounds like you paid closer to $4/watt.
