once one has taken care of making the house relatively efficient this becomes a time to look at thermal pv to charge ones hot water. A sinple array of vacuum tubes to preheat the water even on days when it is raining and cold would have likely driven all of your needs.. This is what I would install over the garage rather than the 8 panels. Remember atleast 15 % of your energy needs goes to heating water.
For those really low output days this is a great reason to have a 10 Kw genset. A couple of gallons of gas and you can charge your batteries in 3-4 hours run time. Since this is just emergency charging and only happens perhaps 5 to 14 days total in a year Still would not kill the bank and yes allow you to fully charge the batteries. For myself have 1 to 1 net metering so one emergency battery is all that I would need for the few times that the power is interupted. Unlike California power costs perhaps 11 cents per kwhour so any more batteries becomes for me a silly investment. I should note I paid $250 for a 5 kw genset. so for longer outages it is kind of a non starter for a longer outage. I dont have an electric vehicle at this point If i did I would likely install 30 kw worth of batteries and use a dc charger and its own system that is not connected to any grid tie or any other needs in the house. Panels are at this point dirt cheap so would not need more than 20 550 watt panels
These Hankooks have a tread wear rating of 600. Very good. The OEM Continental ProContacts have a tread wear rating of only 400. Should get much better mileage with the new tires.
This is one of the best done short reviews on a tire that I’ve seen. Bravo. After a recent blowout of a Goodyear Eagle F1 Asymmetric 5 (Tesla’s 20” OEM for the 2021 Model Y LR), I was prompted to shop for tires and quickly came to the conclusion that Tesla’s electric smarts don’t translate to tires. I like it that your review highlights the important stuff without going too deep into the weeds.
I live in southern California, where the sun is so intense that the glass roof turns the interior into a solar oven in the summer. Wrapping the glass roof pearl white makes a night and day difference!
I don't understand Dec 29 (17:55 on the video), where the batteries jump what looks like 15% (~6kWH) @ 3pm while the power production minus usage appear to be about 1-2 kWH (by my rough estimate). What's going on there?
Have you considered using your car's 75kWH battery as a backup to your 40kWH stationary battery? Would that alleviate all your "not enough battery" worries?
My car does not do bi-directional power transfer. New Cybertruck will do that, as well as Ford Lightning EV, and maybe one or two other EVs. But if there is no sun to charge my house battery, neither is there sun to charge my car battery (which I need to buy groceries, etc.).
Really impressive video. I felt you presented the info at a pace where I could really absorb it. Well done! I do wonder, for the general case, if it's good or bad for every other house to build a system that's much bigger than needed for it's own use so that the other half of the population on the grid are NOT using burned fuels. This would imply a larger battery, the excess capacity of which (ex, over what your house needs) is really only used by your neighbors via the grid. This would mean that the payment system would need to reimburse the panel owner better for their investment and the grid owners need to take less. I've also seen people floating the idea of a large battery per neighborhood (ex, every 10 houses) because larger batteries are more efficient and would be professionally maintained, monitored, and updated. A mini-grid that is resupplied from the central grid where there's multiple dark days in a row.
Hey! My system does not export any power to the grid (the local utility will not allow large systems to participate in net metering - they don't want to buy consumer excess power here in SoCal where residential solar is so common). But micro-grids are great for small isolated communities. The San Diego for-profit power provider is investing in new gas-fired power plants rather than in utility scale battery systems.☹
Hi Chris thank you for the reply.. I'm now ur fan.. your very detail. And I believe your the first to to point out what happen during bad rain weather. Keep up the video. I am planing to get solar because of you. I also live in California is it true there a law limit of 40kw battery limit?
Usually I put more tomato pieces than what I showed, and the diced tomatoes actually have more water in them than a thin layer of sauce. And of course the spinach, olives, and pineapple are all wet. But no, pizzas not dry at all.
Came back and gave this a thumbs up for the dogs! These tires were much quieter than my Pilot Sport All Season 4's. However, they took my 0-60 from 3.45 seconds to 3.56 seconds (including 1ft roll-out). They also took my 60-0 braking from 115ft to 128ft. I have not tested them in the rain, yet. They are identical in efficiency. They are MUCH QUIETER! and the car rides much softer. This is on an EV6 GT, comparing Michelin Pilot Sport All Season 4 tires, all in OEM sizing.
@@Chris21709 I had a set of Michelin cross climate on my model X for about 1.5 years. The front tires only lasted about 18k miles while the rear tires are still good. Just replaced them with these Hankook tires.
Put a pair on the front of my, originally Michelin shod, Model 3 LR last week. Car feels much more planted, with some improvement to the ride. Guess I’ll replace the Ms with Hankook when wear dictates.
I got these in 20” for my MYLR!! They changed my life! I felt like I had an all new suspension. The also run super quiet! No lie these are the bee’s knees’!!
Also got these for my Model Y long range 20 inch tires to replace OEM Goodyear after 30,800 miles. The ride quality seems better as my wife even noticed the Tesla was less harsh on bumpy roads in my town.
They're absolutely quieter, they might be smoother riding, but they're much stiffer for turning. They don't want to turn, they want to go straight. It's a different feel, i'll get used to it im sure this a 23 model 3 performance
Even though you don't care, could you share your wh/mi since last charge of at least 50 miles? I'm curious to know what you get, even if you drive like a mad man. Lol
In middle of charging now. 307 Wh/mi most recent local driving this morning (cool). 285 Wh/mi which covers the longer trip yesterday with air conditioning on high.
@Chris21709 sounds like it shouldn't hurt my efficiency much lol Might even be more efficient depending how spirited you're driving. Haha Considering my original tires are lasting over 28k miles, I think that's a good sign that efficiency will be better than what you got. Haha That and I got wheel covers that actually make it more efficient. I'm excited. I'll likely be getting a set after my 4000+mile roadtrip to Florida.
Never checked it. Get all my electricity from my solar + battery system so not concerned about efficiency. Did notice yesterday afternoon in very hot weather the charge dropped more than normal with the A/C blasting. 🙂
Anyone thinking they can just get by with solar IMHO is fooling themselves. The amount of batteries you need is horrendously expensive. Sun and Wind are counter cyclical. When you don't have one, you routinely get more of the other. The wind is strongest at night, in the winter, and during weather events. For the cost of 10kw of batteries you can buy two 2kw wind turbines. And half the amount of storage.
Never checked. My large solar + battery system provides all the free electricity I use for my car and my all-electric house, so not something I care about. 🙂
This is why I do not like proprietary systems. You are at the manufacturers mercy. Where as if you bought server rack batteries and off the shell inverters etc you pay a LOT less and you can afford to have twin inverters/controllers. If Enphase discontinues this line and something goes sideways, good luck getting the software out of them that matches those batteries.
lol. I'm at 19k miles on my 19" gemini continentals on my Model Y Performance. The back tires are done for lol. Front ones are okay for now. But I, too, will go for the Hankook evo ion as suv. (As for the 21" uberturbines... haven't used them since I got the car.)
I did the same switch to Gemini wheels with continental tires from my 21 inch Uber turbine wheels on my 2021 YP with p zeros ( back tires only lasted 22,000 at 1100 a pop!😮
Two small windmills added to my friends system always gets him past the no sun days. I keep a five hundred generator that I have never used just in case. No worries.
$256 each where I bought them, including balance and mounting. By stock tires do you mean tires used for gas cars? Prices vary greatly by brand and model. See tirerack.com for discount prices for Michelin, Pirelli, regular Hankook, etc. EV-specific tires are a new thing.
I mean whatever tesla recommends for tires. Like the tires you'd get if you took it to tesla for service. I haven't had to replace my tires yet on my S
@@Skippy-Jason-Rock Tesla seems to change its OEM tires almost every year as tire tech evolves. Continental > Pirelli (MY), Michelin>Pirelli (MS), Michelin>Hankook (M3). What they put on your car is not what they are putting on the new Model S. I suspect Tesla service would give you a choice, same as an independent tire dealer. Plus all-season or performance, etc.
Being green means to encompass a whole lot of things the heat coming from your Kim could’ve went back into heating or keeping water at a steady temperature or higher…. Meaning, if you were to use thermal solar panels to heat your water before you heated it with electricity, you wouldn’t have to heat the water as much and if you use the kiln to heat water in store that heated water in a heat exchanger. Going green ask actually a combination of a lot of things that we haven’t even fully understood how they relate to each other. It’s the laws of physics heat water with the sun. I know it’s not always sunny, but if you put it into the ground and let it stay there at a certain temperature do you know that the temperature is always going to be there. More battery than you really need.
I have an engineering degree with several courses in thermodynamics and a boatload of physics. I'm using some of the energy from the sun that hits my roof. It ALL turns to heat, whether used for a useful purpose or not first. I'm not using any grid power, which where I live is 2/3 from fossil fuel, so I'm not burning anything. I'm also not eating any cows, responsible for a large part of climate change and loss of biodiversity, and neither do I fly on airlines, another big producer of greenhouse gases. I'm filling my yard with new trees.
I wonder if installing mini splits would be more efficient, instead of the traditional central heat/central air, since you can turn off the mini split(s) you would need at night and not have to cool or heat the entire house.
I have spent a lot of effort insulating my 1500 sq.ft. house so partitioning it not useful, and especially during summer, I have a large surplus in energy generation capacity. So not so much concerned with efficiency or saving energy. Almost unlimited free energy with no climate repercussions. Typical summer weather here is warm (sometimes hot) days and cool nights. Thanks for the comment!
