You might get more cooling if you add a water mister on the outdoor condenser.
I don’t think those really make much of a difference here in humid Florida where @mstgkillr and I live. Plus the minerals and such in the water can damage the coil.

Mineral content is an issue, but coils with 60 degree water reduce the head pressure and compressor energy needed vs whatever the air temp is.I don’t think those really make much of a difference here in humid Florida where @mstgkillr and I live.

Does Tesla offer any options for parts, e.g. inverters or panels?
Good to hear that some people had good Tesla response. My biggest worry is communication and response. My local installer is $7k higher installation cost. Hard to go with his very highly regarded local solar company at such a price differential. His company also offers Panasonic 25year guaranteed panels. With Enphase micro-inverters. Does Tesla offer any options for parts, e.g. inverters or panels? How good are they at designing the roof layout?
Much cleaner look too @BrettS. I was wondering what was going to happen with it. The wall looks great and since all your equipment there is gray, the GW1 really doesn't look bad there. In fact a GW2 would have looked out of place. Good luck on getting that inspection and then I assume you have a wait for the PTO like we do here in Calif.
Sure, here’s the graph for Wednesday. This was the day I went off grid, so my house was powered by the grid until about 8AM, then I turned off the breaker. My home usage was 75.5kWh, Solar Energy was 73.3kWh, and it took 19.3kWh from the powerwalls.

Here is yesterday where I was off grid all day. My home usage here was 67.2kWh, the solar generated 72.3kWh and it took 31.7kWh from the powerwalls.

And here’s so far today. My house has used 55.1kWh, the solar has generated 71.8kWh (it did better than I thought it was going to when I posted the graph above), and I’ve taken 20.4kWh from the powerwalls.

If you want me to post the home usage/solar generation/powerwall usage graphs individually, instead of all three things on top of each other, let me know and I can do that.
@BrettS Question for you on your usage graphs. The rhythmic pattern with the consistent spikes up to ~3kW of usage (blue graph) seen primarily at night between ~8pm and 7am, is that the HVAC unit or something else or do you even know?
Yeah, that’s my HVAC. It draws about 2.6kWh when it cycles on. You can see it cycle during the day as well, although it runs for longer during the afternoons.
So I was just checking on the production of my system (as I have been doing obsessively for the past week or so) and saw this:

It’s showing my 15.12kW system generating 15.3kW of power, which is pretty good if you ask me. 15.3kW was the peak number that I saw and it was bouncing around 15kW a little during that time dipping down to around 14.7kW and then back up into the low 15’s, but personally I think that number is pretty impressive.
Depends where the limit is.Forgive my ignorance here, but does that mean the 15.12kW a theoretical limit and not a hardware limit?
When the silicon solar cells are created they don’t all perform exactly the same way. Some will perform better and some will perform worse, but the panels are guaranteed to produce a minimum amount of power under specific conditions. It’s possible that some panels may exceed their rating by some extent.
Someone correct me if I’m wrong, but this is my understanding...

Additionally, as mongo stated, conditions can vary quite a lot and it’s possible that the panels were getting more energy from the sun than the what was required for rating the panel.
However it’s also worth noting that the panel rating (and the system rating that is based on the panel rating) is based off of the DC power generated by the panels. There will be losses as that DC power is converted to AC in the inverter. So in the real world it’s not always common to see AC production that exceeds the system rating like that. Up until today the highest I’ve seen my AC production numbers was around 14kW, which I thought was pretty good. At least until this afternoon.
There’s another thread talking about cleaning panels and how much that affects performance. We had very heavy rain yesterday afternoon, so I suppose it’s possible that the rain helped to clean the panels and that’s helping to increase the production numbers as well.
