I’m turning my home made solar system into a tracking system. Details on the construction can be found here. It turns out that the plumbing unions I used work great as bearings and the system is nearly balanced so all I had to do was add a couple linear actuators and electronics to make it a tracker. So far I just have one actuator working. Hoping the other one comes in today.
I’m also 1/2 of a Megawatt hour (500HWH) ahead on my PG&E usage so far. But this yard collector is responsible for 400KWH of the excess production. But the SolarCity panels are 100KWH ahead of the game so I’m pretty happy with SolarCity so far.
