Hoping some of the experts can provide some insight here. I'm trying to include lots of information, as I see that often requested here. Happy to provide more info if needed, just let me know what I can do.
I've submitted a service request with Tesla, and it is an ongoing saga now going on second month. After 2 visits (detailed below), and a Tier 2 escalation, I was told that "everything is operating normally", which I refused to accept, petitioned, and it is being reviewed again.
System: 9.36kW solar roof with 2 Tesla PW. Tesla Inverter 7.6kW. Estimated year 1 production 11870kWh
The first picture is my production on April 3, the last day that the system was normal. It was peaking at 6.7kW on my 9.36kW system, with 46.5kwh total production which is consistent with what I had previously on clear days. This is a representative curve for the latter days in March where there was no cloud cover.
Starting April 4th, on clear sky days, there were sudden dips happening in the mid morning, with peak production subsequently maxing out around 5kw. This curve happened repeatedly for about a week.
When this was happening, I logged into the inverter and it said there were errors with String 3 not being online. Later, I was able to log in to the inverter again and find String 3 was online, but I dont know that numbers I'm supposed to be seeing. This is what it looked like today, at mid-day (highest peak production), still in a limited state.
The technician that stopped after my first service request by confirmed there was a problem with string 3 when he logged into the inverter, but he couldn’t get onto the roof by himself. He said he had to put in a request for a roof team to come by.
A few weeks later, the roof team showed up while I wasn't home, apparently not reading any case file or knowing what they were looking for. My wife at home simply told them production was low, and to call me. They apparently went on the roof, pulled some things up, and called and simply told me that production was low (but not "too" low) and they had to escalate it.
Clearly there is something wrong.
Since April 4, I have not had a day with total generation over 40kWH. Before this day, the norm in a clear day was mid 40 kWH, with this time of year increasing in production given my solar layout. In fact, my daily generation should be approaching 50kwh per day with the system peaking in the 60+kWh/day range.
On a clear day I am still only getting 38kwh
This is my historic production back in June last year when the system went online
The last contact I had from Tesla was that it was reviewed by a Tier 2 person and pushed back saying everything was working in order. Thats clearly not the case, and I argued with the Energy customer support person that it wasn't right, and she agreed to send it to another Tier 2 team. She said they would only expect to have a 0.5% decrease in production per year.
I'm hoping to better understand the problem so that I can continue to push to get this fixed if they come back saying things are still "OK"
Thanks so much in advance!
