About 10-15% down for me yesterday in San Jose. Yesterday walking to lunch I noticed you could barely see the mountains through the haze, and the sky was more grey than the blue it was a day earlier. Clearly not as much sunlight getting to the ground.

My v1 GW updated last night, 21.20.2 to 21.20.6. I will say that 21.20.2 is the most stable release I've seen in a while as far as the local REST API goes, since the auth requirements for the local API started my local logging kept dropping-out every few days and I'd have to kick my script...

I enabled the feature, will be curious to see what happens the first time it kicks in. Then I'll decide whether I leave it on or not. If it works the way I think it does, I wish it had its own reserve level, like the way the vehicle charging during outage feature works, as I might want to set...

Yeah, the Delta RSDs click as the sun comes up in the morning, I can't hear the ones in my attic unless I'm in the attic when they do it, but there are two in the garage that I can hear from my dining room table. The RSDs are just relays controlled by a signal coming from the inverter. I'm...

Haze also affects things, of course. I see a big difference between a hot hazy day and a truly clear day that is just as hot, even though both are cloudless days. Lots of variables.

One thing to note, there has always (as far as I understand it) been metal in the v3 Solar Roof. There's just more of it now than there used to be. In a v2 roof like mine everything is glass, and they had to cut a lot of glass to handle the valleys, edges, etc. It also means there are...

Yeah, mine was basically the same (the plan-to-increase-by being >100% the current usage). I suspect they might be more willing to accept this when the current usage is low, mine was also around 5000 kWh/year. I do intend to add AC, and am sure I'll end up with an EV at some point, so my usage...

It's most common in my experience of manufacturing that the serial number contains the date, typically in a YYWW format, i.e. last 2 digits of year and a 2 digit week code. For example, my PW delivered January 2019's S/N is TG11833...., where the 1833 would make sense as the date code (August...

There's a lot that seems unwise about this to me, since it seems like it might result in exceeding the nameplate ratings. I'd hope the units were actually tested at the higher limits during manufacturing, and aren't just upping limits later and hoping all units work without verification (though...

Yeah, it's hard to say how much the roof with it's airgap between the tiles and decking that should provide some insulation properties and how much the ridge vent each helped since they happened at the same time, but I feel like there was a dramatic drop in my attic temperatures. My attic had...

Similar for mine, I didn't have a ridge vent originally, they cut it the first day of the install proper, just ran a circular saw along the top of the roof once on each side to cut away the decking they'd added to the top. In my time lapses it's about 8 seconds in on the second video (next to...

Hi, two things I'm having trouble with on the new forum look: 1) How to get it to use the whole width of my browser window. - I still have some tabs open from the whole page, they used to use the entire width of my screen. Now I have a huge waste of space on both sides, meaning I get less...

Logging in as customer, and it doesn't do that on login, it does that on completion of registration, whether not logged in yet or already logged-in. So all 4 times I've gone through the registration forms I get bunches of extra clicking and humming from the PW for ~15 minutes or so, then things...

Nope, that didn't help for me. Even logged-in it says registration incomplete, even after doing the registration form 2 more times. And every time I complete the registration it seems the PW goes through another initial calibration cycle, it goes offline and starts making extra noises it...

It's completely inconsistent for me, sometimes I've been logged-out in around a day, other times it's stayed logged-in for a few days. Every time I'm logged-out it says the registration is incomplete, I filled out the registration forms twice now, yet it still says incomplete the next time I...

I've had my v2 solar roof installed for ~3 weeks short of 2 years, haven't had any RFI issues at all, and I have a ton of electronics in my house. A hobby of mine is high-power rocketry so I set up a bunch of GPS trackers for recovering the rockets, and I haven't even seen any more difficulty...

Back to the original question, it only makes sense that boxes powered from the solar system will consume some power on their own, and require some minimum amount of solar production before they can do their job (which in the case of a RSD is passing power through to the inverter). The same is...

That's still not a rule, just a rule of thumb. If your solar system was at the equator it wouldn't be true at all. But in some parts of the US it is probably a reasonable ballpark estimation. From pure sun angle my system certainly doesn't vary 5x from winter to summer. A good winter...

No, the size is purely an ideal operating condition value for any given panel/tile, times the number of them used. It has nothing to do with the installation details or other conditions that can affect production. Like my Solar Roof totals to 13.32kWp, 561 tiles at 23.75W each. But those...

One thing I'll note is that the time specified does matter. In my testing I've found that even with very old dates, asking for 00:59:00 vs: 00:59:59.999 will give you different answers for that final 5 minute interval. It seems like Tesla never consolidates the data, and has like every reading...

I guess I never took a really close look at mine, they didn't really get the inverter location right (it's a lot closer to the utility service than the Powerwall), and I see you don't have all of the high voltage warnings mine has, looks like they tried to indicate where the Diode Trunk Harness...

8am PST today for me, 1.50.1 to 20.40.3. Seems like they went wide with the distribution today. Not familiar with their car versioning, is the .40 the week number? If so that would be late Sept/early Oct, wonder if maybe it's basically the same FW just with a new number.

Like I'd said above, PG&E still reported mine up until they corrected the billing. That data didn't disappear, but no data was ever added after that point.

My PG&E electric usage details stopped reporting when they switched me to NEM/TOU (started out on TOU-A, I have since been switched to TOU-C, have never been on an EV rate). Since there was almost two months they'd still billed me as E-1 my first ~2 months of solar production shows, but then...

I don't know that two panels would be needed, non-backup loads (if there are any) could probably just stay in that service panel. My 1960 San Jose house's original 100A Zinsco was replaced with a 200A service panel ~11 years ago with a kitchen remodel, and Tesla moved more breakers / amperage...

It took PG&E a few months to get my bill right. My billing date was not affected. It wasn't until the bill I received almost 2 months post-PTO where they finally got things right (the bill a month after PTO was still showing me as on E-1, just with less consumption that month), with several...

Mine definitely has some placement deltas, it was obvious that their initial drawings didn't have the vents perfectly placed and the like, so in some cases they just couldn't have put the tiles where the drawings originally suggested. Fewer vertical rows should result in fewer diode blocks I'd...

Probably Gateway2 vs. the original Gateway? Pretty sure they're different enough that they'd have to run different FW.

I also went with black gutters (and had the fascias painted black where there would be gutters, the other fascias matched the house color, Tesla had to replace all of the fascia boards so they painted all of them), with downspouts that matched the house color for all but one that was against a...

Others have seen that before, it seems to be something misconfigured on Tesla's side. I think you'll have to call support and have them straighten it out, seems like sometimes there's an extra divide-by-2 on the total power figure for some reason, or something like that.

25.1 kWh from my 13.32 kWp Solar Roof on a clear day in San Jose yesterday. Within about a month of the winter solstice a tree in my neighbor's yard provides some afternoon shade, the shelf at the end is a brief period where the sun dips below the leaves before it goes below the neighbor's...

I didn't install a skylight, but I did replace a ~8" bathroom vent with a 10" Solatube. I figured it would make more sense to have that install coordinated with the Solar Roof (mine is a v2) install rather than to install on the old roof then immediately change things, but in the end that was a...

On my v2 install they just attached the OSB to the existing skip sheathing.

I'm with SJCE and I only have a single true-up date, not sure where you heard otherwise. I didn't see any reason to stick with PG&E so I didn't. I am jealous of the people in other CCA's that get much better payouts at true-up, but SJCE's is still slightly better than PG&E's as you noted. One...

I would think you should start with your installer, I'd wonder if they even wired up the Gateway properly for solar monitoring, it really should just take proper placement of the Current Transducers (CTs), but if they didn't do that for solar or did it wrong there likely won't be anything Tesla...

Doesn't seem like you linked the right video? I didn't hear your quote anywhere in it, what they clearly said is that the primary reason why it costs 35-50% more is the wells. So if you ignore the cost of the wells the rest of the equipment doesn't really cost any more than a 'high-quality'...

Seems like your Tesla account doesn't have solar associated with it, only 2 Powerwalls. Solar panels also appear in your second picture when they're on the account. The self-powered option would require solar so pretty sure that's why it's not there. If you really do have solar you should...

The advanced options appear within a few days. Seems they want the system to learn your power usage for a few days first before enabling them. I'm not sure whether the 'few days' starts from commissioning or PTO, just don't recall at this point.

If you're adding an additional inverter for the new panels, the easiest thing would be to simply add the new inverter to the existing solar CTs. That should be easy if the inverter AC wiring all runs through a common point. If they don't then things could be much trickier I'd suspect. My...

Powerwall reserve management is one reason. Most of the year I can leave my reserve at the minimum and not draw anything from the grid, because the PW won't run out before the sun comes back up to recharge it. But if the next day is going to be very cloudy it would be best to raise the reserve...

No, you seem to have missed my point, or perhaps how the CTs work. By putting multiple wires through the CTs you can perform simple addition/subtraction. So what I described above would get you exactly the home load, removing the extra solar and battery currents that were not going to home...

That's certainly not true for my house. All of my loads come from a single panel, since I have whole-house backup. Granted there is a PW breaker and a solar breaker that feed into this panel, arranging the wires such that a single pair of 'home' CTs measured everything entering the panel minus...

If one were installing a Neurio to measure their household usage, they'd connect the CT's to the house loads. Tesla uses the Neurio for different purposes, only measuring net grid current and solar current. So in Tesla's case the home load isn't directly measured at all, it can only be...

I saw that my Gateway fell off my WiFi this afternoon, and in trying to get it to re-join it spontaneously rebooted. Also noticed that it now reports 1.49.0, which it had actually updated to mid-day yesterday. So I hope this isn't a sign of instability to come with 1.49.0. :p No release...

Probably means a 90 degree turn, like basement stair wells that go down a bit to a landing before continuing the rest of the way down, I've seen that in a lot of houses, I wouldn't imagine it's an issue but that's just my opinion.

I had one after my Solar Roof was installed last year.

This was certainly the case for me, they had commissioned my system a month before I received PTO, and I was live with the app, seeing my home draw from the grid and my PW % keep dropping closer to 0 over the next month until I received PTO. It's really just a matter of when your get...

My PG&E Energy Usage Details page stopped the billing cycle that I received PTO. So my graph only includes a few days of solar production May 2019, and nothing else after that.

It's more complicated than that. At 100% both sources agree. But at 0% in the app the Gateway's reported value is roughly 5%. The offset between the two scales linearly across that range, though the rounding is also different, the app rounds down while the Gateway rounds 'normally' (0.5% =>...

Ah, if that's the email they sent you at PTO start, I guess that's why I didn't get one, PG&E sent me that email end of October 2018, even though my install didn't start until February 2019 and the final inspection / PTO process didn't begin until late March 2019. I assumed everybody got this...
