So I had my Tesla solar/powerwall system installed one year ago and I’ve gotten rather busy lately, so I haven’t spent much time here on the forum, but I wanted to provide some updates after a year. Here is my original thread documenting my ordering and install process:
Tesla had originally estimated that my system would produce 19,386 kWh annually and they came pretty close. According to the Tesla app I generated 18,897 kWh and according to the SolarEdge app I was at 19,400 kWh. The SolarEdge app has always indicated a bit more power than the Tesla app. It’s also worth noting that I started using my system in “extended off grid testing mode” on 6/25/20 and I didn’t officially turn on the system until I finally got PTO more than 2 months later on 9/3/20. I think I captured a lot of solar energy during those 2 months, but there were times when the system was off or the powerwalls were full and the inverters shut off, so I know that I could have generated a bit more power than I did. I’ll post an update on 9/3 to see how the numbers look for 365 days of full time operation.
Also of note, I wound up producing a little more power than I used. According to the Tesla app my house has only used 18,387 kWh. I was actually anticipating only producing about 60-80% of my annual usage, but because of covid I drove significantly less during this last year and didn’t need to charge my car nearly as much as I anticipated.
Finally, my best production day was May 7th when I produced 89.7 kWh according to the Tesla app or 91.8 kWh according to the SolarEdge app.
In contrast, my worst production day was April 11th when I only produced 6.1 kWh.
New Tesla 15.12kW Solar / 4 Powerwall order in Orlando
I placed an “order” with Tesla for a 15.12kW solar system with 4 powerwalls and paid my $100 on 4/23. I have been kind of dragging my feet with them as far as approving and signing documents because I wanted to get a few additional quotes before I totally committed to Tesla. Today I finally...
