ECO-WORTHY Dual Axis Solar Panel Tracking System Expanded

I would have given the tracker 5 stars but the controller could use a little work. I have two of them with four 455 watt panels on each. A little larger than recommended, but they work and the tracker doesn't seem to have any issues. Yesterday I had winds in the 40-50 mph range with gusts up to 80 mph. Luckily the trackers are on the back side of my house which acts as a wind break most of the time. I hooked up some carabiners with parachute cord hooked to some 4 foot long bungee cords to act like a set of shock absorbers to help. But at 80 mph, the panels move around more than I like. I've purchased a couple of 30 ft long ratchet straps and will try them to see if the tracker is more secure. Those eight 455 panels produce almost as much power as sixteen 375 watt panels on my roof. During the peak of the day my east roof array is pushing about 4000 watts and the trackers are producing about 3500 watts which is more than the 3200 watt rated output. I used Canadian Solar TopCon 455 watt panels. Everything works really well. I just live in a winder than I would like are of Norther Colorado. ;0)

I initially purchased the extended tracker several months ago. It has been flawless. I purchased based a second tracker. Although the installation/assembly was somewhat easy, the written instructions could have been better. Both trackers are running my off grid cabin.

I intend on adding several more trackers this spring.

I was a bit disappointed with the production of the bifacial panels.

A very good product. I highly recommend.

The internal clamps for this system are specialized aluminum extrusions that work in tandem with square U-bolts to secure the solar panels to the horizontal rails. I personally like these clamps as they allow the panels to be mounted without any gaps. Unfortunately, the kit only comes with 32 clamps. I need an additional 24 clamps to mount all my panels. I sent numerous emails without any response. Finally, I sent an email on ebay which did get a response. "Dear customer, I am sorry to inform you that we don't have separate inventory of the solar panel clamps you mentioned. Could you please try searching for photovoltaic (PV) mounting bracket accessories in the shopping mall to see if you can find suitable components?..." Very upsetting since the part is listed on this website in the "spare parts" diagram.

I would have easily given this 5 star review had it not been for the lack of information for assembly, they were not terribly clear. The tracker itself is well made and works very well. The instruction booklet is somewhat lacking. As an example, the clips sent to secure the panels to the uni-strut are unlike anything I could find any information about. I believe they are designed to clamp to the frame of the panel from underneath so that there would be no gaps between panels and that the array would appear quite streamlined. I'm quite happy and excited to have this and I will definitely be purchasing at least three more in the future, I just am not pleased with the assembly books. Going forward, now that I've assembled this one, future trackers should be easy to build.

I recently purchased and installed two Extended Dual Axis trackers and solar panels from Eco-Wothy. both trackers and solar panels arrived with no damage and defective free. I must say Eco-Worthy does provide some of the most protective packing. The system came with clear instructions noting which numbered package to when constructing the panels. Once all systems were installed I was quite surprised with the power results I received through the panels. I am getting between 80 to 90% power output.

I would highly recommend the Eco-Worthy Dual Axis tracker and solar panels. The design of the tracker and panels were well thought out.
