ECO-WORTHY Solar Panel Dual Axis Tracking System (Expanded Version Increase 40% Power) with Tracker Controller,for 10PCS 100W/8PCS 200W/4PCS 400W,High Stability, Multi-Angle Adjustment, for Yard/Farm

Can't argue with what you get for the money. A tracking system for less than 1K is pretty good. I loaded mine with 8x old 50W panels. They crank all day long. My workshop is off-grid and the panels mounted on here are doing WAY better than the 8 you can see in the photo. The pad I mounted it to is 2x2 on the top and goes down 3 feet. Our dirt here is VERY hard and almost like compacted gravel so it's not going anywhere.The good:Easy to put together.Plenty sturdy for our winds with wind sensor.Included unistrut stuff is easy enough.Tracks very well, within its limits. More below.The bad:Stainless hardware requires you to either use anti-seize or watch your torque. It is easier than you would think to make the hardware unremovable.Tracks well but the southern extent of travel is a bit lacking. I am in New Mexico and I don't think it'll actually be able to pull down far enough to actually track 90 degrees to the sun for peak winter.The neutral:Would be nice if the control pad could easily be mounted the correct way. The manual says to keep the wires coming out the bottom and then you have to mount it turned 90 degrees. I am not too concerned about this as it doesn't rain here much but might be a problem in a wetter climate.Build looks a bit loose in the wind but it is holding up great and doing a good job so far.I've had this installed a month now and it is working well. Gets confused on cloudy days but quickly corrects itself when the sun comes back out.My next upgrade will have to be some newer, higher-efficiency panels for this thing. The 400W array is cranking out what it can for power so I'll need to find some of these infamous Chinese super cheap panels in the US to give me closer to 1000W on this backyard sunflower.

I installed first solar tracker last April. Mounted it on concrete in a location that i know gets alot of sun. We have a pretty good view of the sky East to west and South. On a good we get nearly 12 hrs of sun during summer months. This takes advantage by tracking East to west and north to south. The first system I purchased was tracking so well I purchased second tracker during Prime Days in July.Quality very good. In my first review last May I identified some problems with the installation manual and some improvements that could be made to parts.With this second tracker the installation manual had been updated. They did a pretty good job correcting some of the issues.Each tracker has six 195W panels for a total of 2340watts. Several clear days the first week of August the trackers combined to produce over 15.5 kwh/day.Since I wasnt sure where to put second tracker I built heavy duty 48" x 48" pallet out of Preasure Treated 4x6 with 2x6 decking.Trackers look cool (see photo). There is a cool factor. Nice to see them both track the sun like sunflowers.I would advise you buy some protection caps for ends of the struts or somebody might get hurt. The ends of the struts protrude just above eye level.We'll see how they perform over the winter months.

The basic unit has some issues that are easy to work around. The rail system is only suitable for light loads. If your looking to beef it up solid super strut or unitrack can be doubled back to back. Lows and Home D sell 10” long spans of this in 14 ga. You will need to use the biggest washers you can fit isn’t every place you can. After several mind bender mods I was able to cram 4-400W bi-facial panels on it.The oem drive rods will growl over this. You can pick up after market heavy duty right here on Amazon.Not too pricy for 600 pounders. They run slower but run quiet. This will also give you larger pins to manage the extra weight you will be adding. Program numbers will double as well. If you’re wondering if this thing will be worth the effort. The answer is a resounding yes. I’m still chasing all the bugs out of my mods but so far able to overcome all most all of them. The instructions for programming this thing are very basic and do not clearly define exactly what does what.I run KUKA robots for a living and trust me this thing is a hand full so far. I may pick up another one andre-engineer from the ground up. Many of the stress points need some help. All in all I’ve had a blast playing and planning this toy. It may very well pay for its self in the long run. If you stick to the basic unit it will do just fine. I see where they have made several upgrades already from the factory. I’m also seeing a lot of people stop by and ask about solar. When they see it working. Will update as things change.Sun trapping at its best.Update 4/1/24 Here in Oklahoma (Tornado Alley) we see straight winds over 80mph so every thing to beef this up is a must. So far this has lasted through some 40 mph gust in the flat and now tied down configured with bungee straps. All this is with the aid of weather apps and reports. We are expecting 50 mph+ today. I doubled the straps to 8 total. When knowing which way the wind is coming from is a plus. I’m going into manual settings and trimming the angles of the panels about 10 deg. Into the wind. Hoping to avoid some of the lift of the wind to flow over in a glancing blow. It is a must to kill the power to actuators after setting angles and tie downs.You may wonder about the bar clamps in some of the photos. They are a test of some fast disconnects of panels if need be. Fingers crossed for high winds in morning.
