After calculating things and remeasuring I found out I would need bring the ground level up at least 2.5ft to bury the pipe. So, I've decided to go with a closed loop glycol system.

Other than that, we started building the rack today. After some talking with my father in law, we changed the design of the solar rack and also increased the height of it.

In preparation for digging the trench to the rack, we dug out the flower bed around my porch. Digging under the porch will be the fun task for tomorrow.




This is the location the solar rack will sit. We had to cut down a few trees that were in the way.




In the morning we went to the equipment rental place and got us one of these. I gotta say, this thing works like a dream. We had to drill five 10" holes four feet deep. With this machine it didn't even take two hours. Well worth the ~$75 it cost to rent.






Here are all the holes dug, its hard to see but there are five holes dug over roughly 35 feet.




These are the posts we used. We nailed and screwed a few 2x6s to create a 6x6 20 feet long. This thing was heavy! We made and used five of them.




As you can see, its no short piece of lumber, and that is with 4 feet in the ground.




After getting the first post up we noticed we needed to do a bit more tree trimming.




And here is the far post put up. We got all 5 posts put in the ground and cemented in. However, it was too dark to take pictures by then. I'll snap a few in the morning.
