Re: [RE-wrenches] Trackers

Hi Chris, In regards to wattsun, which controller are they using? The website doesn’t give any details. The last one I did used a quite complicated one and it didn’t have easy to use external manual controls. Thx Jay Peltz power. > On Sep 6, 2018, at 1:13 PM, Chris Schaefer wrote: > > Ch

Re: [RE-wrenches] Trackers

I like Array Tek and for offgrid. It is a waste to dual axis track. Less is more! All you need is the array point at the sun with enough tilt to shed snow. Again, Less is more. If it had a failure (and none of mine have) it is still a fixed array until it is repaired. Dave Angelini Offgrid Solar

Re: [RE-wrenches] Trackers

I agree with Bill & Allan on this,  I worked on my first Zomeworks tracker in '89. Trackers add quite a bit of cost and complication, and if they have a failure, they can actually be worse than a fixed array.  The Array Tech trackers would table top in failure mode, which is not good in the win

Re: [RE-wrenches] Trackers

Bill, Wrenches In most cases space is always an issue, sure modules prices have dropped but top of pole trackers have a place along with large ground mount tracking systems. It will come down to economics of the ROI, 20 to 35% more output for 10% more cost, yes yhere is an increased in maintaince c

Re: [RE-wrenches] Trackers

To All, Seen it first hand with existing Northeast offgrid clients that had old pole mounts with lots of generator usage during the winter months. Added a single 12 module DAT and generator usage was down to as little as twice in the entire winter. Others usage was down to just a handful of times

Re: [RE-wrenches] Trackers

Bill, No, I'm with you on this.Given the the greatest boost (~+/- 30%) of daily tracking is during the summer and most stand-alone applications are winter-peak (where tracking adds at best 10-15%), seasonal water pumping is about the only time when small-scale tracking is justified over simpl

Re: [RE-wrenches] Trackers

There are a lot of All Earth trackers going up in these parts. Of course they are made just North of here, so that may be part of it. Dual axis active tracker – seem to be well made and pretty reliable. https://www.allearthrenewables.com/ -Glenn From: RE-wrenches On Behalf Of ch...@oas

Re: [RE-wrenches] Trackers

Bill, If you lived offgrid and had to run a heatpump for cooling in the desert, you would see that either virtual tracking ar a tracker would give you the long hours of solar power to minimize battery use. Dave Angelini Offgrid Solar "we go where powerlines don't" http://members.sti.net/offgri

Re: [RE-wrenches] Trackers

Chris,I thought since solar PV prices have come down (understatement), is it not more cost effective to buy more modules than a tracker? Are there scenarios that the above would not ring true? (As I remember, off grid water pumping for livestock ponds may still be an exception as also, limited spac

Re: [RE-wrenches] Trackers

I have been waiting for a small 6" pole tracker like the AZ125 that array tek made. I could get 2KW on it. They only make the 8" (too much work) and HZLA that I use quite a bit. --Dave On Wed, 5 Sep 2018 14:41:19 -0600, wrote: Dear people: What trackers are y'all using nowadays? I have
