Hi @offandonagain, one minor issue I see with solar estimates: the monthly estimates are inconsistent with the summed daily estimates. My April 2024 summed daily estimates come to 1128.1 kWh but the monthly display shows 1034.5 kWh. Or perhaps they are pulling from two different PVWatts...

Yes there is good chance the paperwork process of getting onto DSGS wastes May-June earning potential, knowing the speed of Tesla.

It depends on the number of events in a season. It seems ERLP has a lower floor but a higher ceiling for payment, as it scales with the total amount of kWh over baseline each PW discharges. Below section of the Tesla ERLP VPP site says a minimum of 7 events for typical payout of $140 per PW...

Just noticed this link via the Tesla app > Virtual Power Plant > Program Facts, info icon. As of April 2024 all new VPP users will be enrolled in the DSGS program. Folks who had participated in previous years will still be in the ELRP program, unless they disenroll and enroll in DSGS...

Hi @offandonagain, I noticed recent Netzero updates referring to Utility Rate Plans. I can't find any sign of this on my app running on iOS, is this feature applicable to all?

I am grid charging but at the hours right before 3pm, after solar has mostly filled the PW, instead of overnight. This minimizes the GC energy used. I indeed used a Netzero schedule automation to do this.

Very interesting. Looks like VPP in CA will be moving to an average kW model more similar to Eversource (New England) Connected Solutions program, which compensates $225/kW for up to 60 events, up to 3 hrs ea, for a battery's "contribution" which is its total discharge during an event, vs the...

Perhaps recent Netzero automations make TBC vs SP superfluous since you have full control of behavior, in which case you are all set. I setup my TBC prices last summer. In case you want to try TBC, one other note is I think 50% for sell is too extreme. If you are on PG&E EV2A, try these...

Hmm, not sure what's going on there. IIRC, it took a couple days for the TBC algorithm to learn the new conditions so it wasn't an immediate change. Also, I think you need to setup analogous Buy/Sell prices for Peak, Shoulder and Off Peak, not just Peak.

Net generator here too. I have 7kW solar and one Powerwall2. My PTO was Sep 2021 so am in NEM 2.0. My provider is PG&E and my CCA is Peninsula Clean Energy (PCE). I have similar concerns as the OP in trying to balance maximizing my annual payout, while using the PW2 gently. To this end I...

Congrats, that's about as quick and seamless a warranty replacement process as I've heard. You may want to check your full pack energy after the battery is at 100% for a few hours, it may go up to ~15kWh

@RKCRLR I use TBC and am able to self consume solar power during peak. You need to do the following hack, go into the Tesla app settings, Utility Rate Plan, and set your Sell Prices to be 10-30% lower than your Buy Prices. This incentivizes the TBC software to act the way you want. For...

Hi @mudder thanks again for the investigation and wondering if you've heard back from Tesla or Intertek? I watched the teardown videos as well, would you mind if I posted links to this forum? In one of the videos you mentioned characterizing the battery pack's full capacity when you get a...

Hi @Vostok see the discussion on what we think are the origins of the 37 MWh throughput limitation here. Practically speaking, the warranty is still 10 years and your PW2 still having a usable capacity of 9.24kWh or 9.45kWh (depending on if you use 13.2 or 13.5 kWh specified original capacity)...

I agree that anecdotally I see higher failure rates in the early PW2s. My own experience attests to that. My first PW2 failed 1.6 years after install, but the replacement PW2 has been rock solid. I thought that Tesla made true reliability improvements for my replacement PW2, but what if they...
