I recently purchased the SunTura HD and I just finished setting it up this past weekend, I'm pretty impressed with how sturdy this kit is because I've got a 8 x 145w tracker and it's about 330 lbs. I'll post video when I've got it all setup (for now I've posted a photo). The project took A LOT longer than I expected. Now onto my question. This morning around 10am the sun was up (mid-horizon) in the sky (June in Massachusetts) with no clouds. I have a bolt mounted on the frame it to see if there is a shadow (check alignment) and it was way off, for some reason it wanted to go east and it really needed to go west to follow the suns movement. I gave it a few hours and checked it later and it was back to tracking nearly perfect. should it matter that much in the morning? When I tuned it I did it in the afternoon around 1pm or so, which about when I checked on it today. I also tried adjusting the LED's this morning but it didn't seem to respond in the right direction.
