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.
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.
