Panels to arrive tomorrow

The panels are to arrive tomorrow per freight from Con-Way freight. Today after work I was able to run a segment of the ground wire through the conduit from the roof through the condit to the inverter location. Basically I need to install the support railing and the #6 copper ground wire to the railing using the grounding lugs but I need the railing splice connectors and grounding lugs. (they have not come in from the shipper yet). Once the ground wire is installed, I can then install the panels and attach the ground to the panels using the grounding lugs as well. I am taking photo's as I go. I will upload the photo's later.

All Stanions Up

All the stanions are now installed and properly flashed. This took some doing and was not as easy as I thought. I also installed the flexible EMT conduit and ran the mc cables through the conduit to the exit near the inverter location. I also was able to mount the sunny boy stainless steel inverter mount. This SMA inverter is excellent quality. The Sauare D AC disconnect is also mounted near the service meter base. Photo's to follow.

24 Stanions Now Installed

Ok, I was able to get off work today at noon and was able to get some stanions up. Need to install 24 more.

Installing More Stanions

Today I installed more stanions. I now have 16 of the 48 required. Its slow going working alone but I only worked 4 hours. If I had a full day, I could probably get the remaining stanions on. Next will be the panel support rails.

System Arrives

Today the system arrived via Federal Express Freight. No problem unloading the components to my trailer. Had lift gate service. I unpacked the system components and verified all was present compared with the shipping list. There was one component not shipped, I notified the solar provider company and the item was immediatly shipped with no questions asked. I began with installing the fast jacks and actually was able to install 4 of the 48 required. I am not able to work on the project tomorrow, I have to attend a conference for my profession. I am having trouble with obtaining the assistance of a solar electrician. I called the solar electrician for this area and he told me that he would not attempt to assist in the installation since he was not the person whom sold the system to me. I had no idea I would run into this problem. According to my state regulations related to solar installation, A homeowner may install his own solar system on his residence but I would like to have a certified solar electrician perform the actual grid tie. I am not sure how all of this is going to pan out. I live in a rather small city and I think he is the only certified solar electrician around. At any rate I am going to keep on working on the installation when I get time.

NEC Codes

I am awaiting the arrival of the system and trying to take advantage of this time to plan every detail of the install so there will be no surprises. I have been reading the NEC codes related to solar installation and I want all codes complied with. These codes are written for safety and performance of the system. Throughout the installation all NEC codes shall be complied with. Today I had a local solar installer come give me his thoughts on the system and he agreed with all that I have planned. The engineers called for #8 thwn-2 wire to be the conductor from my load center to the AC disconnect switch. Today I made access to the load center by removing a window of sheet rock beneath my load center. I then accessed the location where the conductor would exit the wall to the outside where the ac disconnect is located. When I built my house, I put a 1" hole in the brick for this access. I ran 3/4 inch rain tight flexible conduit from the exterior of the house through the 1'' access hole to the load center and properly secured to the knock out lug. The backfeed will be through a 30 amp two pole breaker that was placed in the load center. I did not connect to the conductor to the 30 amp breaker. I marked with chaulk the outline of the disconnect and the inverter on the brick. I then ran #8 thwn-2 wire through the flexible conduitand have it ready for the connection to the AC disconnect when available. All of the connections shall be verified by a licensed electrician to verify all NEC codes were complied with.

Note: My load center has a 200 amp main breaker. This will support up to 40 amps of back feed. If you have a 100 amp main breaker on your load center, the backfeed breaker will be limited to 20 amps.

Flashing Arrives

Today the flashing arrived. I choose to use the 4 1/2 in roof jack stanions for my installation. I definitly wanted this set-up because this combination along with the roof flashing will make for a durable and leak proof roof penetration attachment. I do not want anything screwed into my roof without being properly flashed. Reguardless of what other claim, flashing is the best way to protect you roof. I like the fact that the panels will be at least 4 1/2 inches off of the roof for cooling purposes. I did not want the panels mounted near the roof surface due to the heat that can build up on our roofs that lowers the efficiency of the solar panel. The wire transfer of funds occured today. Hopefully the system will be shipped soon.
The photo's show basics of how I installed the roof flashing and fast jacks. I used a chaulk line to be sure all is straight and square. I was surprised of the quality of the fast jacks, all solid aluminum, with all stainless fasteners. My roof rafters are spaced 16 inches on center. I had attic acces to these as well. I started by drilling a small hole near the rafter through the roof and used this location to measure the remainder of the rafters every 16 inches. I only missed about 3 or 4 through the entire roof. Since all will be flashed, it did not matter that I missed those 4 rafters, although I did seal the holes with sealant.
