I have been eyeing this solar tracker for a while, they released an updated version that can do more panels. Checking to see if anyone else has gotten one yet and has any input on how well it works? I already have the 195w bifacial panels on my camper and I am pleased with the output I get from them.

 
I’d rather have $700 more of fixed panels or batteries. Maybe if I lived way far north like above 55 degrees

Agreed. I live at 55 degrees latitude and you don't even see them up here. Some of the big commercial installation run huge single axis trackers, but I've only ever seen a one dual axis tracker, and its at a local school and more for demonstration of operation. More panels are way cheaper $/watt and no maintenance.
 
What got me thinking about this is I see quite a few of the new solar farms running single axis trackers, so must be something to them. Figured a dual axis tracker would be a fun project in the backyard. I am well versed on solar for RV's, just not home use, yet.

I appreciate you sharing your knowledge on this.

I think there were some states that incentivized tracking installs. Maybe in a location where space is limited for home use I don’t see any advantage. Home solar would be install it and forget about it. I would not even install thermal panels because of required annual maintenance to the glycol system.
 
I know some people on solar FB pages that swear by their trackers. A lot of those are people who have limited space. I see advantages to trackers, especially the use of fewer panels and longer optimum sun angle.

Those with lots of space go with more panels (although I'm unsure why, it may just be bias or maybe they like looking at a long line of panels out their window). And then those same people are talking about how maybe it would be better to have different arrays facing different directions for longer sun exposure.

I would love a tracker (I have limited space), but it would not work well for me.
  • The biggest reason is that every 2 months I have to change the physical location of where my ground panels are because of shading issues. Right now, I am on the cusp of changing location from the northeast corner to the northwest corner.
  • Another issue with a tracker is that it basically needs to be permanent mount. That would mean I would need town permitting. And, they wouldn't allow it to be anywhere but the back yard (behind the house, on the east side), which is the 2nd worst place.
  • And, lastly, I'm not sure it would work in winter because the battery would be too cold.
Note that my household solar is on my roof. I use ground solar panels to charge my battery stations for 8-9 months from spring to fall. I got those stations as backup for winter power outages but figured if I use them on the daily, I would be well in practice if needed during power outages. I use them to run kitchen appliances, the washer, window fans, charge devices and run my computer station when I have reliable sunlight.
