To All, Once again thanks for all of the help and useful suggestions, as well as those who contacted me directly. Yesterday afternoon, I wrote a very long and detailed e-mail to our customer explaining to him that we had run out of options, and that I did not think we would be able to instal

I realize your client is set on doing this, but I installed adjusting tilt racking on the 5 kW solar array I installed on my home over 15 years ago and I can tell you after the first year of adjusting these heavy sections I finally selected an average position and they have not moved in 14 years

The only system I've done with this feature, we used 2 Seas (now Iron Ridge, it appears) racking. I guess if you can limit those racks to being only two modules high, the weight would still be manageable. Still not something that one person can easily adjust, though. Example: http://www.ironri

I so totally agree - during the winter there's not enough sun to make a difference where we tilt the modules, and in the summer we dump power anyway so we've set them for a nice spring/fall angle and forgot about them for the last decade of so. The funny part is I spent all kinds of extra d

Is there a wind resource? Does the wind or solar resource seasonality correspond to the conference center use? Perhaps a hybrid system would be prudent? I wouldn't want to pay for that battery bank Roger Dixon Skylands Renewable Energy, LLC 908.337.2057 cell roger.di...@skylandsre.com ww

This is a funny thread as I spend some of my time doing commercial installs in Hawaii, where tracking and tilt adjust is definitely not happening, and you're lucky to get the panels facing even close to south. The rest of the time though, I'm working with off grid customers that some may ac

Dana: I imagine you can cull some general advice from the Wrenches. Beyond that, it sounds like you have a large design project in front of you. This is something many of us do, for a fee. William Miller At 04:20 PM 8/13/2009, you wrote: Hello All, I have an inquiry for a 40KW+ off grid

HI Dana First I have done a 40+kW Outback in 2003 working fine, but it is on grid. I have a 6 pack Outback Off grid working fine. I do not have anything this big off grid. However my Outback products have served me well. And they are flexible, allowing many configurations. I have done some
