I have the Sol Ark 12k. It is pretty awesome. I could tell by your description exactly what it is. I do not have my solar connected to it. I had solar installed with micro-inverters before my battery. I am AC-coupled. My solar is landed on a sub-panel. I moved most of my house to the sub-panel, and the Load portion of the 12k feeds my panel from the battery.

You will like it. Lots to play around with.
Nice setup.

I'm a data nerd, so I'm pretty excited to see what this can do. I know I'm going to have to wait until the power company gives the final okay, so I probably shouldn't be getting myself too excited right now (much like the fact that I won't have the Mustang for another couple of months), but I can't help myself. :)

We installed a 10kw system about a year ago and just added the Mach E to our garage. Thrilled to be driving solar powered miles! Have not charged at a public charger yet.

We've had our solar system for about 10 years. It's a 9.2 kw system. We usually put back power at this time of year but noticed since getting the mache that we are now using more which is to be expected. The power generation has been going down over the years which is normal. We also live be a dirt road so the panels get dirty when we have long dry spells. With 5 adults living in our house, we use quite a bit of electricity!

We have a 7.5 kw system that produces a peak of 51 kWh daily in summer and a low of 29 kWh in winter. I charge up once a week to 95% on one of my days off (whichever is sunnier) with our pool equipment turned off, and have yet to use a public charger. I'm not tech savvy enough to know what percentage of the charge is coming from the solar panels, but I'm confident it is very high.
We live in an area with a very high percentage of clear sunny days so I feel this setup is a no-brainer and well worth the investment. A Tesla battery provides our nighttime electricity needs and ensures we are not affected by grid power outages.

I believe I used pvlib for the main API for plotting the solar location.

Thanks for the link.
I can imagine an app that would use your phone and step you through plotting the solar location on a picture of your sky area. The phone has location and time and could align the plot over the picture since the sun would be in the picture when and where you look it. You could use that to line it up.
Maybe solar installers could use it to sell solar or predict what was in the way. I am sure other features could be added based on roof angle. The picture just looks so cool.
Does any of this make sense?

It does make sense, and it would be a nice app. I would love to have the time to create it.

Most of the solar installers I know use one of two tools:
1) a neat mirrored, semi-spherical tool into which you place a preplotted sunpath based on one's location and of which one takes a photo. So you end up with something similar except in a spherical projection.
2) A suneye, which is basically a specialized camera+small computer that costs a couple to a few thousand dollars.

A phone app that could do this would be awesome. I have never written a phone app, though, so it would be difficult for me to accomplish this. I can write the algorithm/mathematics, but the UI and etc is not something I have experience with.
