This is a photo diary of the installation of our solar array. The array sits on two Zomeworks UTRF-120 trackers and one Home made tracker.

My neighbor has a mini excavator so he came over and dug the main trench and roughed out the post holes (holes are 2 feet in diameter and 5 feet deep)

The trackers sit on 6" schedule 40 steel pipe (6 5/8" outside diameter). I bought used pipe in 20 foot lengths for $8 a foot.
I only need 15 foot long poles (5' in the ground and 10' above) so I had to cut them down.

My little bandsaw can only cut through 4' pipe, so I had to cut a bit, roll the pipe, and repeat.
The photo above is the final cut and you can see the previously cut section below the blade.
As you can see here, the pipe is pretty thick, so it took about 40 minutes to cut through it. Fortunately I wasn't in a hurry.

Naturally the bandsaw is solar powered. This is the 240w array that feeds my workshop, which is completely off-grid.

Braced and ready to pour the concrete.

and here you can see the poles all lined up and waiting.

Concrete poured, hardened and the supports remove...

I need to paint the poles before installing the trackers, PV panels, and Enphase micro inverters.

Ok Paints dry enough

Time to start installing the trackers.
Here you can see my pattented method of applying the required ~200 ft-lbs of torque (notice my feet are off the ladder)

Panels installed on the trackers

Picked up the Enphase inverters today

Need to build some brackets to install them on the trackers.

Inverters installed.

The array is now finished and just waiting for the final county inspection and approval, then power company will turn it on.
