So now you are selectively slicing quotes? It is working as intended - it is also not working as this user desired. And, to be clear, I have nothing but sympathy for his discovery that the reality did not live up to the hype.

It is clearly working as intended in the MA situation (the CA situation with the red flag warning may well be an issue) - Tesla themselves (Storm Watch | Tesla Support) say it is based on NWS, and the evidence says it was - with a user near the coast, in the warning area, getting Storm Watch...

It illustrates the fact that PWs are a finite resources, and we all have to choose how to allocate that energy. I am not missing the forest for the trees, just providing the iron-clad solution you were looking for. Since, as Tesla documents (regardless of marketing) it is intended to only...

But it does not require an active role - set it to 100% and forget about it, and you will always have backup power.

This is a very good point, and something that ideally would be taken into consideration in general (even though it seems not to apply in the particular situation in MA, given the relatively low number - under 1% - and relatively spread out nature of the outages in that particular area.) The...

The nice thing is that there is an iron-clad solution, which is to set the reserve at or near 100%. If storms that the NWS does not classify as severe are frequently knocking out power, that is the solution. To me, this is not a workaround as this indicates a grid deficiency somewhere...

And I think this is the key point. It was absolutely a major weather event, but the severe storms did not apparently (based on what I have seen so far of NWS alerts) extend that far inland. Having lived in that area for a number of years, I was just going to add the same point that it is...

I am pointing out that not all "weather" is severe weather. There has to be a cutoff, and expecting a Storm Watch every time a thunderstorm comes through is unrealistic. From what I've seen there was legitimate, severe weather in parts of MA, but not in all of MA. Those with severe weather...

Where Storm Watch does not react to a covered warning, it is an issue (we just don't have the information at this time that Tesla ignored any NWS warnings that should have triggered a storm watch in these particular events.) Speculating, since Tesla has not ever been explicit about Storm...

No doubt, there is a disconnect between the marketing implications and actual implementation, as is unfortunately all too common in marketing. But your words "severe weather" and examples like you cited of "extreme weather" being used in the first paragraph are the key. Just like so much...

While anybody has a right to be upset when things don't work as expected, the point here is that 1) expectations need to be reset for how the product actually works, and 2) while improvements can be made to the product, there are limits, including general prohibitions against grid charging...

While 300k+ (looks closer to 500k) in MA are without power, Middlesex county seems to have about 4,500 (< 1%) without power. Another user in SE MA reported Storm Watch did activate for them, as I would hope it did for many in SE MA, the Cape, RI, and at least coastal parts of CT. But it seems...

Do you know how the NWS actually evaluated the storms in terms of warnings? Looking at your location right now, I see only a wind advisory, which I would not expect to trigger storm watch, but there may have been warnings yesterday/overnight. And for prior storms, sometimes the trigger seems...

Thanks for posting this. Looks like similar specs to the original (v3.0?) tiles, but lighter as well - 3.1 psf vs. 3.4 psf.

Nice - based on the lack of search results for that part and lack of other posts, you may be one of the first installs with the new tile. With a ~23% increase in output per tile (presumably same size tile,) that really starts to close the gap on their solar panel offering. It is still less...

One other thought in favor of getting clarification sooner.... The (original) v3 tile strings are limited to 35-36 tiles per string (I think I've seen both mentioned.) Our roof has four 35-tile strings on it. I would be concerned that the change to 209 could be an attempt to limit the size to...

In the meantime, you could reach out to your advisor - at some point it would be good to have an electronic copy of the updated layout (and depending on the AHJ, they may need to submit the updated plans at some point as well.) We did also receive a one-page Datasheet on the modules as part of...

That would be interesting, if accurate. Are there any boxes around or other way to validate the model number of the tiles? The active PV tiles we had installed are part "SR60T1", which is 58.47 W, and that matches your original plan (256 tiles ~= 14.97 kW.) And, I believe the boxes that Tesla...

Having previously had these, along with a 50-foot tall pine hanging over our roof (since removed due to age,) I had no issues with needles getting in, nor with water overflowing. But, removal is definitely an issue, and these types of gutters require more expertise to install properly (to get...

I think it is a plausible argument and might win the day. On the other hand, the code does not provide any language that has an exception for something being unique, and the logical extension of this would be that if the entire house was designed with some proprietary lego-like connectors, this...

We do have gutter guards with our solar roof - ended up installing the metal mesh style as that worked best with the roof (we had previously had the reverse curve style, but the way that mounts would not work with the solar roof we were told.) So far, no obvious issues, though we don't have as...

I am not sure why the price went up so much - it is possible they have been updating their pricing recently, but also double-check on the settings for powerwalls and for show/hide incentives. In any case, it is definitely an estimate, so you really will need to put down a deposit to get a...

Does your agreement mention gutters at all? If it was completely silent on gutters, I would think you have a case in that the normal expectation would be if they are silent about something, it will not be altered by the project. However, if the agreement did say something about Tesla removing...

I think it was supposed to come from scale, no marketing, and fewer options. But, I agree, it certainly would not be clear - particularly to a prospective customer - that it would be at the expense of what seems like reasonable service expectations. I have also thought that an SLA would be...

I think we generally agree - my initial point was Tesla couldn't hide behind "whole home" - as you suggested Tesla might try - by excluding a compressor because it is technically outside the 4+ walls of the home since it means nothing. In the end, "whole home" is to me not particularly relevant...

It seems to me the answer is Tesla, who could then take it up with Hyper-Engineering, depending on the agreements those companies have in place. In this situation Tesla is the expert, and it is their responsibility if they are committing to supporting the A/C to ensure that it is compatible...

Regarding small claims vs arbitration, at least my contract with Tesla provided within the arbitration clause that I also had the option to file in small claims court. Not sure if that is in the current contract, but both might be options. Not disagreeing that small claims might be best - just...

I agree the argument is strongest where everything is on the same plane, though there is still a question of whether it qualifies just because it happens to be part of what Tesla might call a system. Taken to an absurd level, if Tesla designed modular homes around its solar/battery product...

I get the argument of it being an integrated system, though this is not what Tesla was saying about the same product as recently as a year ago. I do not know what prompted the change - whether it was simply an internal reassessment or some guidance from the IRS - but it is a change. And...

I don't think it being outside of the home would likely be an issue - and I expect "whole house" is really just marketing puffery anyway. The more important question is whether Tesla knowingly wired the compressor into the backup panel. If so, then they were essentially saying it is part of...

What is your roof angle? That is a pretty extreme difference - we have half our solar roof on our north-facing side, and our average expected production at the solstices is 31.1 vs 11.9, and our best within a week has been 47.6 vs 17.7, so in both cases a ratio of somewhere between 2.5:1 and...

As @jjrandorin said, it takes time. And, until you get PTO, there may be extra factors. Once you get PTO, there are are a few ways to tell, depending on how much effort you want to put in. Tesla should have given you an annual estimate, and you can just wait for the year after PTO and see if...

Just a couple thoughts on this - I would continue calculate PWs separately, mainly because it is still an option to do re-roof + solar panels + PWs, instead of solar roof + PWs. In MD, with the state solar incentives should be enough to justify the roof or panels on their own, and then PWs can...

Agreed that PWs should be excluded as should the cost of a new roof. (And if you don't need a new roof, it is almost certain solar roof will not be competitive with panels.) Even with all of that, with power costs typically cheaper out east and often lower performance (weather, and in your...

That is certainly a different position than they used to take. I would feel like it is a bit of a stretch for exactly that 1-tile extreme example (and I did not claim my entire roof, based in part on what Tesla was advising at the time) but I would certainly be more comfortable if Tesla and a...

Glad you got that worked out as it will almost certainly be better for you financially. Just be prepared for SREC prices in MD to fall. Right now, SRECTrade is paying out (after fees) about $72-$73 per SREC, based on the $80 SACP level this year. But, starting next year, the SCAP drops to...

It seems like you have a good handle on what the numbers are, so no need to use PVWatts - but a good resource to know is available if/as you get curious about the numbers. It looks like a reasonable layout from Tesla - seems like they pretty much maxed out the South, East, and West roof planes...

I don't want to get into guessing what any individual wants as OP can certainly make up their own mind, but at this point I don't see anybody getting mired into details, just asking some reasonable questions to understand how to judge what they want and would need. My point is that I think it...

In fairness, the stories on TMC present a biased picture given that people tend to post when they have issues. And, of course, your issues illustrate how other installers and utilities can also be the issue. The Tesla solar roof people seem to at least be marginally better than their average...

It will be interesting to see actual data on this at some point, including how effective the raised design is at shedding the heat in different climates (and I could imagine things like wind could be factors.) Nominally, it seems like the solar shingles would only be about 5% less than the...

As @jjrandorin suggested, PVWatts is a great resource to get an estimate of your production. It is worth noting that Tesla tends in many cases to be a bit conservative (perhaps 5-10%, though it is not consistent) with its estimates compared to PVWatts. The one thing that is missing here is...

As others have said, past experience has been that Tesla has been a real challenge for timelines, which presents a particular challenge for new construction. However, as you are seeing, there are at least some indications that they might - and I emphasize might - be making an effort to work...

While I do not know what is typical (and the CA folks seem to have a different process,) at least around here the utility is definitely involved before construction and requires an "Approval to Install" to proceed, and there are at least potentially consequences for not doing so. Doing a very...

Yes, the 21.31.x versions seemed to trigger this behavior. However, at least for me (still set in backup only mode) 21.35.0 reverted to not doing this any longer.

In MD. Maybe it is different in NV - I know some folks in CA were reporting that they still were required to buy PWs, so perhaps NV is that way as well.

What does Tesla's ordering page say? PWs used to be optional, then were required, but are again optional in at least some parts of the country. Where I am, the default pricing includes PWs, but there is a "Remove Powerwall" option.

Good update, and glad to hear Tesla is finally trying to do the right thing. But I really do wonder (and we will probably never know) whether this whole incident was worth it for them. They certainly generated a lot of bad publicity and unhappy customers, plus the costs involved in dealing...

The gutter piece is not uncommon - it depends on the type and positioning of the gutters relative to the roof and really is something that requires the site visit to determine. In our case, the gutters couldn't even be re-installed, due to the gutter guard system we had, so new ones were...

While I generally agree with this approach, the other piece that needs to be addressed is what was contracted. In particular, what (if any) specs were provided that indicated the number/size of inverters and what was the estimate for annual production? It does all get a bit murky, because the...

While the expense part definitely could be an issue, I think the latter statement requires some qualification. I have not seen evidence that the same size array, pointed in the same direction, will show any significant difference in production whether the array is of panels or the roof...
