About this Item:
  • More power generation: Single-axis tracking mounts maximize efficiency by keeping your solar panels facing the sun at all times. Single-axis tracking mounts can boost the power generation of solar panels by at least 30% compared to traditional fixed solar mounts.
  • 270° adjustment: The single-axis tracking mounting system allows light sensors and controllers to work together to push the rods through 270° of angular adjustment so that the solar panels always follow the sun's rotation, absorbing solar energy from the north-southeast and north-west, thus generating more power.
  • For different panels: The single-axis tracking racking system is also suitable for different sizes of solar panels. Up to 4 panels can be installed when width of each is less than 22in. Up to 3 panels can be installed when width of each is less than 29.5in. Up to 2 panels can be installed when width of each is less than 44.8in. You can install the board according to the actual needs.
  • Stability & installation: Stability of single-axis tracking mounts still deserves your attention. Wind resistance level >L8 and pressure resistance >5400PA are sufficient for most environmental conditions. In addition, the installation is very easy and requires only 4 simple steps: â‘  Use expansion screws to fix the base â‘¡ Connect the A-E rods and actuators to the main pole â‘¢ Installing the Controller â‘£ Installation of solar panels.
  • Easy to use: The setup is very easy, you only need to operate the controller to complete the control of the single axis tracking bracket system. SET Button - Automatically track the solar mode. FLAT(M) Button - Automatic flat bracket mode.

This single axis solar tracker is mainly about squeezing more output from limited space, especially for ground mounts or roof replacements where drilling is already planned. The controller can lay the array flat in low sun or high wind, and the actuators have held up for more than a year in some setups. The tradeoff is that wind, maintenance, and eventual motor failure are recurring concerns, and the space it needs can rival simply adding another panel. For many layouts, extra panels still look like the simpler path.

I just ordered eight of these. Even if the motors break right away, they're cheaper then six premade ground mounts. I pulled my solar off the roof to get a new roof, and I'm not going to drill another 800 holes in that new roof. Also, I'll put these in the field for much, much better afternoon solar throughout the year. I am jazzed. And heck, if 8 work, I'll get 8 more and finish out the old microinverter system. The bad news is, I have to dig maybe 250 feet of trench. :\
I have a brand-new roof also and is so concerned about drilling into it??? Sigh.

Do not drill. Do not roof mount. Bad!

Now that I look at the specs, I'm only going to get two of my old panels on each of these with tracking. Still, 16 panels of sun tracking is better than nothing. ~3200 watts with a 30% boost for tracking = 4160 watts equivalent. I could also skip the sun tracking and just use these as mounts with two extra panels on each. 32 panels = 6400 watts, but hacky. Or have the additional panels straddle for a firmer mount and less weight each with them all aligned. 3 panels each = 24 panels = 4800 watts. Also hacky. But then I cannot adjust seasonally. Decisions to make. I'll probably start with two each and good spacing and then move to four if I feel confident.

Roof mount is awesome (to most roofs) if you at least add the mounting when redoing the roof. The panels actually protect the roof increasing its lifetime and can reduce heat. It's like having a roof on your roof.

How do you mean "add the mounting when redoing the roof"? Would that somehow make the leaking issues less likely?

I'm sure it can be done perfectly, but not likely so.

Probably not the best place to get a detailed answer, there's 1000s of YouTube videos about the basics of solar systems.

I have some old Candian Solar panels that we removed when redoing our roof. And enphase microinverters. A lot of people pretty much give away old panels when they redo their roofs, as most solar companies only want to do new installs, so you may be able to get free panels if you look around.

I imagine the caveats on it are likely enough to discourage you from doing that. I have the two-axis one, and I'm nervous even in moderate windstorms, though it's on a concrete base that's 6ft across and 6ft down, and nominally weighs 17,000 lb.
Do you mean wide? If you mean you poured a depth of 6' of concrete then I'm asking which mobster you burried.

It does seem like a rather large amount of concrete for ~4 panels.
