Yes I recall you had the benefit of the free at work charger which will help reduce your overall home consumption significantly. My system is in my signature below, but will add it is SW facing on a single large array so "highly efficient" as I'm told by the installers. On a excellent sun-day, I'll generate 65-70 kWh per my graphs.
I've played with the data and the net export/import is interesting from the Tesla app, but it doesn't quite translate to the bill because of the TDU. i.e. you'll get charged for every kWh delivered while you sell at your fixed rate. You appear to be on a good MP2 rate since you said you're paying and selling at 11.7 since the recent rates are now variable export not that fixed that you have. However your buy rate is $0.117 + $0.049 TDU. Keep that in mind as your monthly bills come in and you have a chance to analyze. I've seen exciting bills under $10, but those are the ones that I'm proud to highlight. If I'm being real, Houston has more hotter months than cooler months. My 12 month bill average was $45/month and that was based on the older 0.08 rate maximizing 2 PW usage. This $45 monthly average isn't going to break any bank especially considering the system cost, but just beats me up on the personal business case when I went down the solar route in my total ROI estimates. I like looking at the data and seeing how I can should manage it. I have a few spreadsheets. lol
Last month's first real bill with our new MX was $200. And we didn't even drive much. Compared to $9 bill the same time last year was the trigger for me to pay the $200 cancelation. If it's $200 in November, I can't imagine what the bill will be like in the summers. And like you, if that stupid CT actually comes out... that's another huge consumer in the garage. We're a 2500-3000 kWH monthly usage home already.
I was excited to see my bill usage report. It was $2.58 for the week and that's with heavy hosting for the holidays with christmas lights on the house on. I called in and asked to convert my 18month free nights to a 48 month plan since I don't want those plans disappearing any time soon.
Like I said, these #s aren't going to break the bank..but interesting and hopefully helpful for you or anyone else reading this. Since you have the free charge at work, your plan may work just fine. Ride it out for a few more months and extrapolate your usage and estimated bill. My original models were close, but did not anticipate for the 30-40% increase in electricity prices we have today.
. Or maybe Cheap guy life. Lol
