    Heterojunction and UV Tech

    👍 Yay Wild Blue Yonder! Dad was Navy, Army Air Corps, Air Force, then flew for JAL when we came here. I guess I'm as Bratty as they come! I am very much looking forward to Solar + Powerwalls.

    Heterojunction and UV Tech

    Hey @BGbreeder , just so. 👍 As my home state is Hawaii, I gotta admit the Yokohama is comparatively filthy. We face National Route 1 to the south, so traffic dust is a real thing, even though tire dust and diesel particulates are way down, it's still there. A few times a year pollen is wicked...

    Heterojunction and UV Tech

    Thank you for the reply @BGbreeder , Yes, I wish I could get more info, too! My guy is coming today with the Choshu installer, so hoping he has some info. The Premium Blue is a new product, but the company is pretty big, and still around after 40+ years ... a good sign. Yokohama has a LOT...

    Heterojunction and UV Tech

    Hahaha! A record for me, for sure. So about those Premium Blue ... You must've read the same article I came across, "UV Solar Panels are a Scam." Yes, UV only makes up only 4% of the radiation that hits the roof ... on a sunny day. I think they are trying to harvest that wavelength because...

    Heterojunction and UV Tech

    Yeah, China and Japan seem to have a lock on ping pong, lol. We were at a party about 30 years ago, and this fellow was boasting of being captain of the Princeton team ... my 5'3" wife humbled him soooo bad. Military Brat? I came for here HS on Yokohama Navy Base (Yo-Hi), and met my wife at...

    Heterojunction and UV Tech

    Haha 😂 Ishikawa Kasumi, 3-time Olympic medalist. Just retired, I guess Choshu Industries identifies with winners. I know this, because my wife was on-course to play with Team Japan … then met me! Apparently, no regrets, as she’s still with me 50 years).

    Heterojunction and UV Tech

    Hey All ... again, The PV + PW system I am looking at is taking shape, and as I learn a bit more, I seem to know a lot less (bear with me, Super Newb). My project guy is coming to assess my building for install and fill me in on what can and can't be done with regulations here in the middle of...

    PV + PW in Japan

    Harry, I don’t see anything like that in the preliminary proposal, and not sure about specific local regulations, which my guy is investigating now. After seeing some of the unit prices, plus additional installation charges, I’m not sure how much I want another part that could easily bump...

    PV + PW in Japan

    Harry, I hear you. While we have milder temperatures, we have immense humidity swings, pretty constant seismic activity , and typhoons. Unless I REALLY need more electronic gizmos with clear economic benefit, I want the simplest system possible. (who was it that said, "the best part is no...

    PV + PW in Japan

    Hey @wwu123 , thanks for this and your later post. Haha, this is turning into a saga! "The Story of the Cross" or "The Shadow of the Cross" ... Oh, wait! Those are on my bookshelf. ;) That white steel cross is from our first rented place in '87, and after a few years of use was up in the...

    PV + PW in Japan

    Hey @zTesla, thank you. It seems the panels I’m looking at are the Half Cell type with Bypass Diodes, which (according to YouTube, mind you) are a little smarter at ignoring cables and such. The cross is not much wider than a cable, so hoping for the best. it Comes off with just three bolts...

    PV + PW in Japan

    @jjrandorin and @hmcgregoraz thanks for the ideas of Microinverters and Optimizers. I watched a few Y-Ts by Gary Does Solar on the topic, and now have some (small) clue (Solar Panel Shading ) I haven't heard back from my project guy yet, but will definitely want to find out about these...

    PV + PW in Japan

    Hey @wwu123 , thanks for the reply. Indeed, Japan authorities are conveniently blind to a lot of such situations. This property was owned by my late father-in-law's company since just after WWII, and was originally a woodworking shop and dormitory. I think if someone tried to start a business...

    PV + PW in Japan

    Konnichiwa, @jjrandorin san, Arigatou! "Pencil out" is a new term to me, but I've already read it about 10 times since investigating a solar harvest/storage system. It's fun to find out what's going on "back home." (quotes because after living in Japan 50 years of my life, I guess this is home...

    PV + PW in Japan

    Hey @jjrandorin , thanks for the reply, and a very fair question. Maybe I'm still formulating that question in my head, and need more data? Well, that's not precisely the case, I DO want to get a more control of our energy costs, and not just be paying TEPCO whatever they tell me forever. The...

    Hey All! I live in Yokohama, Japan, and am looking at Solar Panels and a pair of Tesla Powerwalls. Please understand I am a carpenter and mechanic, and know a bit about IT, but a newb about Electric Stuff ... please be kind. Wife and I went to the Tesla Owner's Club All Japan Meet the end of...

    2023 Model Y no USS discussion, incl. Discussion of Tesla Vision Firmware

    FYI, January 2023 Shanghai MYP, delivered March 1, has fully functional USS. My 2020 Fremont M3SR+ (shown back-to-back on Delivery Day) had latest updates here in Japan, but never lost functionality. I was surprised (and happy) to see this, as Japan has a LOT of tight driving/parking situation...

    MYP Suspension Travel

    Thanks for the reply @gaabbee, I don't have any way to compare my Shanghai MYP with a Fremont build, but while there are a few differences in some features, I haven't any reason to think suspension is one of them. I am fairly confident in saying the suspension is much less harsh than previous...

    MYP Suspension Travel

    Oops! Forgot to post details of my "suspension travel enhancement" devices. ;) RAYS GramLights 57CR 19X8.5J +35 with Pirelli Cinturato P7 255/45R19 resulting in a total weight saving of 34.8kg, about 77 pounds.

    MYP Suspension Travel

    After a month of driving my Shanghai (I specify because there seem to be several differences) 2023 MYP with "square setup" lightweight, narrower 19" wheels and more comfort-oriented tires, I can definitely report that I feel no need for more suspension travel. Though the rear was effectively...

    MYP Suspension Travel

    Hey @HonchoNI , thanks for the reply. Not THAT snarky, lol. :cool: Since I didn't (past tense, now that I've taken delivery since starting the thread) have any choice except RWD "short range" and Long Range Performance, we chose MYP. Which means we are not gonna find used MYLR parts in...

    Waiting in Japan for MYP

    Well, It's been a couple-three days of new car ownership! Sadly, not that much time to drive, though I did get some time to go out and admire (and check!) and wash "RJ Dream." The wash had to happen, as Japan in in the depths of Cedar Pollen season, and just one short evening of gusty Spring...

    Waiting in Japan for MYP

    Another month gone by, and 3 more days to Delivery Day! So got only one offer on my Model 3, and that was $3,000 less than Tesla's trade in offer. Japan really is in the doldrums for the used car market of any make. March promises a higher price, as much of the nation has the end of the...

    MYP Suspension Travel

    Hey @240vPlug, thanks for the reply. I suspected the 21” Uberturbines would contribute to some harshness simply by 255/275mm of tread supported by a small amount of sidewall. I am already planning on getting a ”square” set of 19 X 8.5J wheels with 255/45 Cinturatos (I’ve always like Pirelli...

    MYP Suspension Travel

    Hey All! MYP delivery scheduled for March 1, and getting excited ... and perhaps a bit anxious 😐. Trading in my '20 M3SR+, I would really like to NOT get the "terrible/horrendous ride quality" some folks talk about. My test ride was a lot better than my M3, sooo ... My question is about...

    Hey from Japan!

    Hey James! Just subscribed to your TMJ channel, and also Scott down in Kansai. Three gaijin Tesla fans makes a club, right? Lol. You probably figured out I'm in Yokohama, and I assume you are in Tokyo? Maybe a Tesla meet is in order? Or maybe we can just show up at a テスカス meet ... which is...

    Waiting in Japan for MYP

    Got a Delivery Date the other day, March 1st at 4pm. I have to pick up at the Tokyo Delivery Station, no other options available. It's not too far, about an hour by train or by expressway. It's not "official" until I've paid, and can't pay until I decide on the trade in. My M3SR+ is posted...

    [UK] Would you buy another tesla

    Answered “Yes,” and after 2-1/2 years with my M3SR+, waiting for a MYP. Delivery Date in 5 weeks, ordered 6 monthis ago, before a LOT of recent hullabaloo. However, none of that stuff bothers me. I live in Japan, and have investigated all alternative EVs available here, and even test-drove...

    Waiting in Japan for MYP

    Gulp! So much for a cheaper bottom line … Trade in offer also a LOT cheaper! My previous offer expired on November 30, so in 43 days, took an $8,000 hit. Yikes! Win some, lose some … but not going to just lie down. Contacted my Advisor, asking (nicely … not gonna organize a “mostly...

    Tesla cuts prices in China, Japan, South Korea and Australia; will the US be next?

    Exactly. That particular market is enjoying a roller-coaster/see-saw of competition just now ... which will probably continue for a while. But seriously, I don't see any kind of real protest getting traction, and certainly not any kind of litigation. From my perspective, it was a brilliant...

    Tesla cuts prices in China, Japan, South Korea and Australia; will the US be next?

    Hehe, Seems those same folks crying “unfair” forgot that they received a government subsidy last year that the new price cut people did not get. As Scar from Lion King said, “Life’s unfair.” (Oh, yeah, he was the selfish bad guy in the movie) Yeah, I imagine if everything you buy is an...

    Tesla cuts prices in China, Japan, South Korea and Australia; will the US be next?

    Japan has had no price changes for at least 6 months, when I ordered my MYP, but yesterday got a call that my car was in production, VIN by the end of January, and delivery end-February to early-March. Got an email with "changed terms of contract," and indeed showed a 10% lower bottom line. I...

    Waiting in Japan for MYP

    Checked Tesla homepage this morning, no change. But while out with wife today, got a call from my Tesla Advisor, and she said my car was now in production, should be finished in a few days do I still want it? I said, “Well, yeah …” We were in an underground parking, so reception was not so...

    Do tires last longer on 19" wheels than on 20" wheels?

    Hey @antio ! Warning! General statement: 19" tires *may* last longer and be more economical, because 1) 20-21" tires tend to be more sport-oriented, and unconsciously (or consciously?) tempt us to more (ahem) vigorous driving, 2) sport-oriented tires tend toward higher grip vs longer wear in...

    Curb Rash on brand new Model Y Rims... How should I repair them or do I need to replace them? Worth to claim insurance?

    Ouch! Definitely get a professional opinion. If the wheels are not bent, repair may do the trick. My own experience tells me to never cheap out on wheels and tires, especially on a car that can quickly pass a ton (100mph). Here in Japan, wheel repair is frowned upon by the National...

    Lucky Bags

    Haha! After starting this thread, 50th Anniversary Lucky Bags a bust so far. Only one place open January 1st, and (according to wife) No Fun. Today, January 2nd, had plans to go to another department store, but a long FaceTime call with US family threw us off early morning groove. My...

    Waiting in Japan for MYP

    Hahaha! Yeah, the Keijidousha (used to be 360cc, now up to 660cc) light trucks are still all over the place, especially the countryside. But now gross weight and commercial limitations keep them from doing nearly everything. Back when, I used the 1/2 cubic meter mixers to deliver small...

    Waiting in Japan for MYP

    Good point, especially in Tokyo, where a lot of older vertical parking lots are. Here in Yokohama, things went vertical about a decade later, most having a bit taller specs. Width is also a problem for the incredibly tight individual parking machines. But my wife worked with me at the...

    Waiting in Japan for MYP

    After reading a bit here, I'm intrigued by all the Tesla online ordering drama. I first heard about the Model Y coming to Japan in July '22 or so, and scheduled a test ride asap. Here's a screenshot of the price of MYP with Red exterior and white interior. At the time, ¥8,810,000 minus...

    Tesla Model Y build quality, manufacturing refinement and assembly

    Haha! More likely, WE have to invest in that ;) . MYP coming soon. The one I test rode was pretty good around town, but didn't try on the expressway. If any worse than my M3SR+, will probably invest in the Unplugged Performance Luxury Coilover kit UP Luxury Coilover Suspension. Cheers!

    Really?!? R. Daneel Olivaw? Chetter Hummin? A thousand pardons if that is your real name. I assumed you were using a character from one of my favorite authors, Isaac Asimov, my bad. No disrespect, but I'm flummoxed. Eto Demerzel, Asimov Fandom I salute you for a great name! Happy New Year...

    Mobile Repair Experience

    Nice report, @Kokukenji, I've had a few minor things done on my M3SR+ over the past two years, but always at the Yokohama Service Center. I've never used Mobile Service, even though their appointment app always tries to lead me there. My "problem" is that the SC is just 10 minutes down the...

    Waiting in Japan for MYP

    So waiting just past the 3 month mark, I'm now officially ready to take delivery! Tonight is New Year's Eve, and 2023 is 12 hours away. We got a call from our Tesla Advisor asking if we were really ready to get the car. Hahaha! But I guess a lot of folks back out, or are waiting for the...

    Tesla Model Y build quality, manufacturing refinement and assembly

    Hey @flynndean, I am sorry you are dissatisfied with your new car ... that is sad. I do hope that Tesla comes up with a reasonable alternative sensor system with Vision soon (my own MYP ETD is Feb/Mar '23). Maybe they will also allow music through the app of your choice? Indeed, I noted poor...

    Am I being an idiot by not taking delivery before year end?

    Good for you, @tubaprde ! Your first sentence, "My situation is somewhat unique" was certainly true. I assumed partner and family, my bad. Sorry if I made you uncomfortable. My advice stands for a lot of people, but I think your case is well thought out, and sensible. I had to laugh at your...

    Tesla Model Y build quality, manufacturing refinement and assembly

    Hey Daneel, er @Eto Demerzel from Japan! I agree with your thoughts after owning an import ;) "Ame-sha" (American Car) M3SR+ for 2-1/2 years. It very much reminds me of my '76 Honda Accord hatchback, in that it was Honda's first try at a "real car." The tech was amazing, but so many things...
