Hello,
New to this forum section. We are a ModS and ModY household and are in the planning stages for solar + Powerwall(s). We are in south central Texas so there will be plenty of sun. Our purpose is to have backup power for as long as reasonable (2 days?) as well as offset the cost of electricity for the house. We use quite a bit of energy at the house with teens at home all day due to pandemic etc....
We have used anywhere between 1500 KWh to 4000 KWh per month depending on the time of year (hot summers in TX). As I mentioned, we have 2 EVs that charge at the house (one of them 2x per week since I drive a lot), 2 AC central units, and pool equipment (pump etc..). All our appliance except for oven/washer/dishwasher and microwave are gas operated.
Tesla recommends their large system (16.32 I think) and 4 Power walls. In reading here, seems like most people do not go with the Large system and have more PWalls. We would like to have a stable backup process when off grid with the panels replenishing the PW as much as possible during an outage. I know we will load shed some things (only run 1AC, go to Supercharges instead of charging at home, etc...) but wanted some opinions as to what size of system to install. Definitely new at this and looking for input. How about the inverters/tesla gateways? What else am I missing that I may need (like panel upgrades - house is 3 years old so dont expect much here)
We actually put order in with Tesla and hope that it can be modified after assessment.
Thoughts/recommendations?
Thanks, JJ
