Is there an analysis of PV plus powerwall versus PV only? I'm trying to justify 1-2 powerwalls as we have "only" lost power for 4 days (hurricane Irma) and 11.25 days (hurricane Ian) from hurricanes since 2017 Does anyone have any spreadsheets or similar to give an analysis of the above or a...

Are there folks considering using the cybertruck as a stationary/mobile set of powerwalls? My initial thoughts were the 75 kW is actually ~5 powerwalls plus a basic truck that I could combine with my 11,655 PV array. Legally I cannot disconnect from the grid, but hurricane Irma caused >5 days no...

folks, i got a quote of $11,500 for a powerwall plus gateway install (Ca$h) $13,500 financed that seems a tad pricey.... can anyone share please

Has anyone in the US or elsewhere, gotten info about becoming nodes in a VPP (virtual power plant)? It looks like _something_ is going on in Australia. Is anything going on in Puerto Rico or even much smaller projects?

I am trying to gather information. I have an OBDB recorder hooked to my datastream ostensibly to lower my insurance rates,. I have a PHEV, not Tesla, but am getting a model 3 long range later this year I drive 1 pedal driving exclusively, with high regeneration. both 1,000+ mile trips and 5...

here is a link to Australians proposed VPP, Virtual power plant, using (proposed) 1,000 PV arrays and ~7kW battery banks for a 7 megawatt (5 megawatt usable) power. I would really like to buy/rent/PPA/whatever a PV array from SCTY and a powerwall (or 2) with inverter that has capability of...

I'm not sure if this has been discussed elsewhere or answered so apologies in advance. I am fast approaching 70 and have a friend with a Z3 who probably has had several TIA's (transient ischemic attacks)(mini strokes) while driving and had a "time discontinuity". driving, then suddenly parked on...

I realize this is a somewhat non-sensical question, but I am trying to vaguely find the "weight" of 85kWh of electrons. "It takes 6 x 10^18 electrons to equal a coulomb. A kilowatt hour is a measure of power. An amp is equal to one coulomb/second. A watt is volts x amps. SO, if you had a...
