I realize it is about expectation, but I am also worried that it wasn't installed properly. Some backstory: on the last day the installers were on-site, the foreman said he was finished at 1PM, then the whole team proceeded to hang around for an additional 1.5 hours, crawling all over the roofs again, checking this and that. It turns out that the panels weren't outputting what he expected (he didn't give me a number he was expecting though) and they couldn't figure out why. He said he would return on a very sunny day and retest - but he never returned, there was never another visit scheduled to check this out. Next came commissioning, then inspection, then PTO. So I've been thinking that there could be something wrong with the installation since then. Since Tesla won't help check it out at this point, I'm trying to determine on my own (with the help of all the folks here) whether or not there is indeed something that is installed incorrectly, which could bite me in the a$$ later. If it turns out that everything is installed properly, and 45kW per day is the best I can expect, then I will be satisfied.
Having said all that, the only "promise" I can find in my docs is the Interconnection Agreement, which states 12774 kWh. I'm pretty sure this is a conservative number, but I guess this is the minimum they promise. The last customer service person I spoke to told me that they expected my arrays to produce 1500 kWh in June. It looks like it won't reach it.
I am not sure about the inverters either, all of this is new to me.
Thanks for your help!
