I live in North Texas and have 2 Powerwalls, 2 Trane 17 SEER AC, 5 Ton and 3 Ton. Last summer was my first experience with the heat and PWs handing the load. The PWs did fine with the exception of draining quickly usually to nothing once solar power power dropped. I now have 4KW and 1 PW on order with installation scheduled soon.Hi folks,
I am moving to a new home in a couple weeks, and am trying to validate whether the plan below is financially viable.
There are several energy plans in my area for "Free Nights and Weekends" where you only pay the TDU charges. I don't get enough regular sun to use solar - but would it make sense for me to get Powerwalls anyway?
I live in South Texas, HVAC use is HEAVY. My power bill in the summer months is about $300, and about $180 in the winter. That breaks down to
Energy: $0.071400 PER KWH
TDU: $0.044700 PER KWH
plus $8 in tax/fees.
If the PowerWalls run my house during the day, I can remove the majority of the "Energy" line, which would save me between $100-200 per month depending on the time of year.
My thought is -- what if I have the Powerwalls and my car charge at night during the "free" period, and then use that energy during the day, so I'm not consuming during peak hours. Rinse and repeat.
I have a brand new 2800 sq ft home with 2 AC units, and I'm thinking 2 PowerWalls would be plenty to keep me running for a full day. I don't know much about the loan length/terms for PowerWalls, but could 2 Powerwalls pay for themselves in this way within the warranty period?
My electric plan is free nights and .15 per KW Peak use. Charge my Model Y Performance and Model 3 Long Range during free nights. The PWs will discharge during the free time unless I manually set the mode to backup only from TOU.
I don't calculate payoff time with solar. I look at solar/pw as an investment with a monthly return for me of $200.00.
