Are used Zomeworks Utrf168 Trackers worth 2,000.00

Re: Are used Zomeworks Utrf168 Trackers worth 2,000.00

I have a Zomeworks tracker that was made for 8 panels 1 ft by 4 ft (old Arco 35 watt panels), and I bought it used many years ago. It works, and probably should have the shock absorber replaced soon, but it is proabably 15 to 18 years old. When I added another 1.5 kw of PV to my system, I priced a lot of trackers and other mounting methods, and decided that it wasn't worth buying a new one, so I built an adjustable angle ground mount, since I have room for it. As suggested, do the calculations for estimated output both with a fixed mount and using the tracker you are considering, and see if the total cost of the tracker versus a fixed mount gives more power annually than spending those dollars on more PVs. I found that our Outback MX60 almost paid for itself, though, just because it allowed me to use smaller cable (higher voltage string of PVs) for the 250 feet from the combiner box to the controller.

I think that the Zomeworks trackers are reliable, as they have no electronics. The installers that I know that install dual axis trackers figure that motors and electronics are standard maintenance items over the life of the system. Disadvantage of Zomeworks is slow response in early morning, and it is only single axis tracking, so it needs to be adjusted seasonally for tilt.
