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: ① Use expansion screws to fix the base ② Connect the A-E rods and actuators to the main pole ③ Installing the Controller ④ 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.

I'd unhook it and bring the panels inside during a Hurricane.

Looks like it holds two full size panels? Would be cheaper to buy a third panel on fixed racking and get higher total output.

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. :\

Attach solar panels to the laser beams and you can /recharge/ the sun!

You get the ultimate tier green energy bonus card to show off.
Only if you also put solar panels on the sun

Hmm I passed on the big trackers in the past, but one of the smaller ones (well two of them) actually sounds enticing to atleast try out.
Panels are getting so cheap I wonder if it is worth bothering installing trackers instead of just putting in more panels.

Not usually, had to be very specific circumstances.

Trackers limit density because of the shade they cast, and they require robust anchoring as well.

Add in more maintenance and things to go wrong or break and it becomes even less desirable.

For me I'm a solar educator so I always want to try things so when I give an option I can back it with experience.

You're much better off just getting more panels and/or better panels. That's an incredible amount of money, work and concrete for very little upside while they work, and a major headache when the motors start failing or there's a major wind storm.

Ground mounts cost more, and I'll still have to dig all the trenching, run across the bridge, and so on. We also have a lot of shade down in the canyon, so catching what we can catch would be nice. Then there's the ability to mow underneath, since we're in a high fire area, and I can't do that with basic ground mounts. I think, on the whole, it's a worthwhile experiment, even if I just re-aim them four times a year by hand.
I looked at doing a pergola mount, even going so far as to design one myself to save money, and it was just a hell of a lot of work to get them off the ground, more work than these mounts by far.

Is tracking worth it vs just getting more panels?

Yes, but you'll have to calculate where the sun will be 8m and 20sec later since the relative position will change by then. You cannot just aim where the sun is now if you want to start laser-targeting it.
When running past someone spraying them with water, their relative position will be different, yet they didnt move so no need to change aim. if they also moving, yes need to aim where will be. which is this? I have no idea.

Will it reduce the power bills? And how? Will it power at least all the fans and lights every day?
