Hi all thanks in advance for any info it’s much appreciated! Long story short we bought a house with an existing uleased 8kw solar system from Tesla. We have 10 more yrs before lease is up. Our new house has propane for water, heat and oven and a swamp cooler for ac. Want to go all electric and install a heat pump for central heat and air, electric water heater etc. We also just bought an EV that we average about 20-25kwh per day. If I add a system to the grid I will need to replace the service panel (only 100 amp) plus pay pge for adding to the system and would also want battery backup for outages. If I go off grid i could charge my ev off of the grid tied system(the system produces about what we drive per year). I could also use the 30 amp grid tied plug to charge my batteries through the backup generator plug right? Seems like a no brainer but not sure if I’m missing something that would make grid tied system better. Thank you!
