The panels rare REC, and use HJT technology.Are you using monocrystalline panels?
So today was a really mixed bag.The panels rare REC, and use HJT technology.
Heterojunction Technology (HJT)
HJT solar panels have three layers of photovoltaic material:
Top layer: Amorphous silicon catches sunlight and light that reflects off the layers below.
Middle layer: Monocrystalline silicon turns most of the sunlight into electricity.
Bottom layer: Amorphous silicon captures any remaining photons.
You should have waited until December then you would have had to postpone it to spring.So today was a really mixed bag.
We were delayed by ice. It rained very hard before turning to snow and went well below freezing last night. So we had to wait for the Sun to burn the ice off.
The next problem was I had not seen their materials, and when I saw the conduit it was much heavier than I had been led to believe. There was no way this could be installed on the composite Smartside rigid stack siding.
At that point we almost canned the project. However at the last minute the solution came to me. We can use the wood corner pieces. This however means going through the roof over the barbecue/outside kitchen and down to ground level. It leaves us with a long run under the lowest part of the siding along the concrete foundation. So there will be a lot of concrete drilling. This is doable.
Then the biggest set back. As soon as we decided on the plan, the electrician got a text and picture from his wife. Their truck has been involved in a serious hit and run in their driveway. There were parts everywhere and some got into the road. So he was gone for the rest of the day dealing with that.
Anyhow we did get all the mountings for the panels installed on the roof. The panels can not be installed without the electrician present.
Monday and Tuesday look like rain days. Due to our roof configuration we have determined we can not do roof work in the rain.
So it looks as if Wednesday will be the earliest work can recommence.
Booked for Thursday November 7.So today was a really mixed bag.

So we got the system complete today, and it now awaits inspection and the installation of the reverse meter by Dakota Electric Co-Op. Everything went very smoothly.Booked for Thursday November 7.
Of course, Mexico will finally pay for it all. Wonder what the interest will cost them from 2017.looking nice and tidy !
Don't worry about Trump, he'll be too busy building the wall, fly cargo planes of illegals back , etc.![]()
I am surprised they didn't install some of the lower rows further to the left of the upper rows, close to the vents to reduce shading.I took some more pictures today.
This is a view of the connection up to the panels.

So the panels have not changed the appearance of the house significantly.
With the sun on the panels they should produce 7.6 KW.
The state electrical inspector will be here on Thursday November 14. If he passes it, and I anticipate he will, then Dakota Electric can place the reverse meter and the system can go live. So there will be no more news until Thursday.
Blue Raven Solar have not installed a system on an ICF home in this region before. So it turned out that I did a lot of the design from output of the panels to the main service. This has taken a lot of hours and negotiations. I am very happy with the installation at this time, and expect the hard work is in the rear view mirror. One thing I do know is that there are very unlikely to be any mechanical issues, and I don't think any part of it is about to fall or blow down. In a frame built home the system would attach to the exterior of the home.
I encourage members to consider solar projects, there is a big tax right off which will cover about a third and the sale of the reverse electricity flow should be close to self financing. It also makes the home more valuable at resale. I would be happy to advise any interested members, especially if you have good south facing roof space.
That was late evening and the shading is not significant. We can not add more panels as NEC prevent more panels than will provide more than 20% of the electric service rating. The service is 200 amp which is pretty standard, so the max output of the panels can not be more than 7.5 KW. This is a bad limitation.I am surprised they didn't install some of the lower rows further to the left of the upper rows, close to the vents to reduce shading.
You want to know why? It's because assuming that they know this fully is a bad idea and it would be safer to assume that they DON'T know it.The rig past inspection last Thursday. The inspector was impressed and put the green sticker in the cabinet.
The latest hold up is to get the provider to sent the certificate of completion to the power company.
Also there was a hassle over the power company being worried about phasing issues. The provider also seemed to have a hard time with it.
However I have explained the issues to the satisfaction of all parties. There is an Enphase IQ8X inverter in each of the twenty panels. There is a master phase locked loop controller that keeps all 20 of the inverters in phase with great precision. According to the spec the inverter is referred to as a switching design. So this means that each inverter has a 380 watt class D amp. That probably accounts for their high efficiency and very good distortion specs.
Hopefully I have explained this to all parties satisfaction. Why I should have to is a fact that astounds me.
Those IQ are certified for grid tide system so why are they questioning? Oh, they don't comprehend or read the specs on them.The rig past inspection last Thursday. The inspector was impressed and put the green sticker in the cabinet.

Oh, boy, do they do that with all solar installations or just yours because of the IQ8.We are now near the finish line. There has to be a witness test, involving the a Blue Raven Solar Tech and Dakota Electric for noon December 4. If the system operates to Dakota Electrics satisfaction the system will go live. So that is two weeks from tomorrow.
All of them.Oh, boy, do they do that with all solar installations or just yours because of the IQ8.
One mans garbage is another mans treasure. Mother nature does things as such. Nicely done. Power company surely will not be happy with the tax base lost. You'll be warm and toasty while some of your neighbors freeze.I am not a garbage Trump supporter, but the Harris signs are covered in snow today. Nature played a Halloween trick round here.

No the power companies love it, as they have to meet Net Zero targets. These schemes reduce their capital outlays, so they really encourage them and are supportive.One mans garbage is another mans treasure. Mother nature does things as such. Nicely done.
