why not allow it to tilt directionally too by changing just one actuator? seems not well thought out as it could be

I think there are so many possibilities with linear actuators working with solar panels. Great work.

In your design, you have to watch if one actuator fails or does not move at the same speed/distance this will cause a twisting of the panels. I am not sure if you were going to automatically control the angle do this manually.

Cool project, my only concern would be high wind events and it being susceptible to damage acting as a huge sail. I live at a more northerly latitude (49th parallel) so the winter/summer solar angle difference is large, a system like this would be ideal, thanks for sharing

All this is great if you don't have any of those pesky building inspectors asking for "wet stamped" engineering plans and calculations or proof of a proper building permit. Also, your actuators would probably last much longer if you turned them over so rainwater cannot run down the shaft and damage the motor & drive components.

Great video. I also bought similar bi facial panels from a local FB sale. Mines are 535W each. Bought 10 of them. Already placed mine on a very cheaply made ground mount since I don't know how the sun tracks in my place here is GA. I'm about 1 hour from Athens; I'm in Powder Springs Ga myself. I went with an off grid setup. Eg4 6000xp and 48volt configuration. Which wires did you end up using ? What gauge and how much did you pay for it ? I have yet to wire mines since I have another row of 5 panels to do.

Hi James :) Great work! I've found actuators are less likely to fail if mounted "upside down", with the motor up, that way moisture doesn't seep its way down past the seals and spoil the motor over time.
