I had to look up those zip codes on Google maps and unfortunately I don't know those areas. From a brief look at https://www.accuweather.com/en/us/atasc ... =7/01/2018 and some months around it, it does seem pretty warm there.
Unfortunately, it is way too early to tell how the 40 kWh battery will hold up in terms of degradation. It takes us about 2 summers to find out. However, you do have an 8 year/100K capacity warranty unlike us 24 kWh folks (w/5 year/60K capacity warranty).
Recently again, I was able to keep my battery a few degrees above 70 F when it go to 90 F outside.
There's no way during the hotter months of my year I could choose not to charge because it was above 55 F. Even in cooler months, since I charge mostly at work for free, I still will be doing the bulk of my charging when outside air temps are above 55 F.
Notice his delivery date is in Jan 2011 and 4th bar loss was in March 2016? He was down somewhere past 30% capacity, maybe 35% or 36%. He got no takers at $4500 and donated it. It didn't help that he was a remote part of CA. I bet if he were in the SF Bay Area, it'd have been snapped up at that price.
Unless something changes the vast majority of my charging will be at home overnight/early morning timeframe.
Sounds like I should just use it albeit be smart to a point & make use of the warranty if I need it. Especially since I can drive about 1000 miles a month & track with the battery warranty timeline perfectly. It will be very interesting to see what the replacement pack specs will be in 10 years.
