#tesla #solar #powerwall - Auta a dopravní prostředky
Would anyone be interested in an energy channel? Wouldn't really be car related but more on the production, distribution, storage, and usage of everything energy!
Duhhhhh
Hell yes. Full send, please. This is very important, and was, for me, an important pre-requisite to have in place before buying an EV.
Yes. So many avenues to go down.
I would love it, but please try not to make it all about Tesla. I would argue most home solar installations are not Tesla systems and they don’t operate in a LOT of states.
@@ScoobyFermentationit would be a lot of grid scale stuff, mostly beyond home energy
Undecided with Matt Ferrel said in one of his videos that there was a Tesla bug that was overstating power production. He said Marques Brownlee had the same bug. Maybe that explained the 15 kw production on a 10kw system.
It was showing double the actual output so quite possible. That is, Marquez and Matt were showing double the amount of output compared to what they were getting.
That’s right, it’s a known bug. Generating more KW than the rated power defies physics, so it’s obviously wrong. Can’t believe Tesla solar hasn’t fixed this bug for all users already.
Yes, this. It is important that this be mentioned.
It is hard to figure out when the charge the battery. It depends on what you’re using, what you used, and the weather the next day. Why charge full if it’s sunny. And then do the inverters support and smart controls? Don’t think so.
Tesla misstating facts like with their EPA mileage fantasies? I'm shocked I tell you, shocked!🤯
Been living with a setup like this for almost 4 years. Life is good being your own utility company.
you still need the grig lol...
Especially him. Over 50% of his power is grid power.
@@alanmay7929
You do if you size your system to take advantage of net metering. But you can obviously size your system such that you can live completely off the grid. However, why do that when, as was mentioned, you have net metering?
Now with that said, electric suppliers are getting scared and are forcing politicians to change the rules on net metering, such that while it still exists, maybe they sell you electricity at 20cents per kWh, but they only buy it from you at 4. In cases like that, if you still want to go solar, it makes sense to have more storage (preferably LFP, which can handle more charge/discharge cycles) and live off of battery power at night, so you're using the grid less and less.
I’m in the same boat. Installed solar and battery first in 2019, sized to accommodate going all electric eventually, and then added EV, heat pump and heat pump-driven water heater. The gas line is locked by the utility now, couldn’t use it even if I wanted to.
Same. Purchased a total of 2 kw from the grid last month. Yeah, that'll do. And running 2 x EV's.
2 minutes in and I'm so jealous. That's exactly the home setup I want.
All good except for HOA, a layer of "the man sticking it to you" I wouldn't tolerate.
I wonder what's the point of batteries when you have net metering? Avoid 3h downtime in the last 2 years?
Love my PowerWalls! They were awesome during our last Hurricane. We lived off grid for 11 days!
I only have one but man it is so awesome when the power goes out. So far we have only lost power a couple of times for a few hours each time but the only way I knew is the notification on my phone from the power wall. The switch over was instant.
I went through a 10 day outage from a hurricane 5 years ago. I spent that time researching solar. I installed a system like this with 3 powerwalls and I have coasted through multiple hurricane outages since then.
I have powerwalls and solar. I charge my cars off the grid at night and export during the day. I live in CA so the cost savings is significant, I can get back over 2x the energy I export. I believe energy storage in general is part of the overall long term benefit of EVs that detractors are missing. Picking up renewable energy and storing it for later will benefit everyone, and better energy storage will come directly out of the mass production of batteries for EVs.
Tesla's integration here is next level Apple grade stuff. I am so impressed with the integration and the continuous adding of features, the "overflow solar into the car" being one of them. One negative I can see is you can't set a charge limit on the batteries so they do charge up to 100% every day. In theory that is not good for the powerwall's battery chemistry. In the winter I run my batteries down as little as I can and still arbitrage rates, however during the summer I need all the power I can get from them to run my two AC units so they get run down a lot lower then.
Exactly! His changes make no sense but cycling cells for nothing. Produce during the day to the grid. Consume from the grid during the night.
What power wall battery system do you have?
powerwalls are all LFP, so charging them to 100% is perfectly fine. Their cycle life is crazy long
@@MidnightO42 Powerwall 2s ? I have powerwall 2s. I could never find any concrete info from Tesla but the internet seems to think Powerwall 2 is nickel cobalt manganese.
@@blanketwodahs6741Fairly sure. You can confirm it yourself by dividing the kWh for the unit by it's weight. Per google: LFP batteries in EV applications were initially resisted, primarily because an NMC battery has an energy density of 150 to 300 Wh/kg while LFP battery cells have an energy density of 90 to 160 Wh/kg.
based on powerall 2 specifications, I got ~122 wh/kg - squarely in the lfp range
I installed a DIY 10kW 30 panel system for $5000. I made a video about it to make people realize that the systems can be cheap and DIY friendly if you employ a simple ground mount design, and are willing to tackle a relatively simple project on your own. I did this with no prior experience in this area or special equipment or tools. This is the real goal with electric cars, to have the ability to power them with the sun. I don’t have a battery back up yet, but I will be getting my cybertruck in about a month and hopefully with the provided gateway, will be able to use it as a battery back up and have the ability to charge it with the solar panels. I am grid only at this point. Looking forward to the content.
Would you mind posting a link to that video you made? And did you buy the panels used or new?
@@XDRoX619 I'm assuming this is the vid czcams.com/video/t35PsE61Jd0/video.html
We installed a 11.5 kw system a year ago, and I love it. After rebates it ended up costing about the same as a Camry and now I've got free electricity for the rest of my life.
Free? You just pre-paid and if the power goes out, you also lose power. You did nothing to help yourself or improve anything. You now has an added risk, another company to deal with and no upside. Unless you spent another Camry's worth of cash for batteries, total waste of money.
Well, maybe only if you plan on living 10-15 more years. Contrary to people what are told/think, batteries and solar panels do not last forever. And, they also lose performance over the years even prior to their ultimate failure. They also "break" and do need periodic maintenance with circuit boards, wiring and battery issues. A person would need have a *significant* electric bill to even remotely justify this over a short 10-15 year period.
@@markmonroe7330 30 year warranty, so that's why I say the rest of my life.
@@markmonroe7330 most solar panels have a 25 or 30 year power output guarantee of over 80% of original capacity. Panels won't break, there are no moving parts. The inverter will die after maybe 10-15 years. I have a 10 year old EV and the battery is fine, still on around 75% of capacity. The reason solar has been adopted all over the world is because of its reliability.
Solar cells lose efficiency every year. So you will slowly lose efficiency. Large hail can also destroy them. Just look what happened to a huge solar farm in Texas.
Yes, I have solar and have followed you for 2 years and just joined your channel. You Out of Spec reviews on the electric cars are the best. I'm looking to purchase my first ev in June 2024
Great great info! Yes, we need more of this.
Rob is my hero - awesome setup albeit expensive, definitely GOALS
Dropping in to say I enjoy your other videos too but this subject is usually more interesting to me. I can't afford a $90k EV, but solar can actually pay for itself over time so it's something more likely to be in my future. Your friend was very gracious to allow the access and to answer questions at the end. Sweet guy, and a good look for the solar/EV community to have people like him evangelizing!
Installed a solar array on my roof two years ago, talking to several installers, including Tesla. Ending up going with twenty seven 400 watt Q-Cells equipped with Enphase micro-inverters. Tesla was price competitive, however, there were other concerns. Tesla resists customization on their installs and refused to incorporate micro-inverters to help deal with shading issues. It was also difficult to get a human to talk to and there were persistent rumors about overestimates on power output. Very happy with my current Q-cell setup. My home uses about 11,000 kwh's/year. The solar array produces about 9000 of that and, in addition, Dominion Energy gives me about $400 in additional credits each year, allowing them to count my production towards state requirements on the utility to produce a certain amount of energy from renewable sources. I charge my BMW i4 almost exclusively at home adding about 1350 kwh's to drive roughly 5000 miles/year.
AMEN! I also chose Enphase for these reasons with no regrets.
String inverter setups use optimizers which handle shading the same as micro inverters
@@lemongavinenot Tesla. They are an old fashioned string inverter. You don’t get panel level views, and have no idea if a panel is underperforming. I have seen their arrays with panels on north facing roofs, etc. Poor conduit work, finishing a job with people waiting months for interconnection, etc. They are so hit or miss. Love the car (own a Model Y and have some stock) but their solar business is a mess. Best batteries in the game though. If your roof has obstructions or shading avoid a Tesla system.
Great video - similar setup with Model 3&Y, 2x Powerwalls and 40 Panels (Panasonics) producing 15kw peak in San Diego… with 25k miles between both cars we only export energy! Love it!
With my Tesla Solar system, I have it set to drain to 20% to power my house. Storm watch would charge it to 100%. When it felt a storm was approaching that could cause an outage. And I always had the ability to immediately charge the battery, if I thought something, that might not be a major storm but enough that there could be an issue I could change the setting to accommodate that.
I would keep the powerwall between 20 and 80% and only leave it at 65% minimum if storms are expected. He would import much less electricity. I wish solar was practical for me but I'm a low user of electricity and there is no payback yet in FL. Nice showing of this great system.
Yes, Out of spec energy would most likely be one of my favorite channels
A Tesla solar roof pretty much only makes sense if you have to do a major overhaul of your current roof.
A solar roof almost never makes sense financially. It’s significantly more expensive then just a traditional solar setup and a simple
Roof replacement. But they sure are cool
We're in the middle of the transport and energy transition. You do a great job of covering the transport element and it makes sense for you guys to cover all of it. Have fun, there's loads of content.
I would absolutely love to see more content regarding solar and battery back up solutions.
With regard to his panels pulling in more energy than their rating...that can happen on full sun, cool/cold days. The panel ratings are based on performance at certain conditions, including a certain temperature. Solar panels do better when they're cool though, so that can lead to what you were seeing, provided the inverters have the extra capacity to handle it.
I'm in the UK and have had a solar PV+Powerwall 2 installation for three years. I've also had a TMYLR for two years. I have 16x400W Sunpower panels on a south-facing roof, feeding a 6kW SolarEdge inverter. PW is AC connected, so provides up to 5kW. My energy distribution network operator placed an export power limit of 5.4kW, so there's a gizmo to throttle the inverter if necessary - actually rarely happens. We have smart utility meters with 30-minute reporting that allow energy suppliers to offer a range of time of day import and export tariffs tailored to EVs, heat pumps, spot-market pricing, etc. I run the PW with the recommended 20% backup reserve because we rarely get power outages and they don't normally last longer than 30 mins. We did have one event when our electricity supply cable joint broke and the PV+PW ran the house off-grid for three days until power was restored. Good job it didn't happen in December! Storm Watch will charge and hold the battery at 100% if wild weather is forecast. This system provides 75% of house energy annualy, 90% if I include smart overnight charging at cheap-rate in the winter. We export 50% of what we generate. I found that exporting surplus solar during the day and charging the car overnight at cheap rate works best. I have a 7kW myenergi smart EV charger. Tesla and our energy provider make available to download loads of very useful system performance data, which I have squirrelled away over the past few years for analysis:)
Awesome! Appreciate all the information you share with us. Very helpful. Thanks for all your hard work and long hours.
Let me say great video, I love the fact that it’s a great way to draw energy and have a peace of mind, and an energy channel would be nice. Thanks for the education
Yes to a home Solar PV, Battery, V2H focused channel.
I have the Enphase version of what's in this video, waiting for Enphase bi-directional charger and Rivian to support V2H.
In San Diego we no longer have net metering for NEW systems. Utility wants to pay 2 or 3 cents a unit and charge 39 cents a unit to replace it! Unless a a battery that has 5 times the storage is installed, the payback period is probably increased by 10+ years. If CATL or another competitor can produce a lower energy density (heavier) battery with excellent cycle life, homeowners have the option to shaft the utility that IS shafting them. Also, joining the Tesla VPP program yields far more income. Converting DC to AC and AC to DC for charging your EV is losing 16% of that power, when a low power DC charge directly to the EV keeps that loss to simple line length.
You can build your own LFP batteries for a 1/4 of the price. If you don't want to build, 5kWh server rack batteries are about double the $/kWh at ~$1300. Which is still about 1/2 cost over tesla. Their system is very nice, but it is pricey!
Upfront costs mean DIY the way to go.
Yes - energy channel please! This was great & would love more on this charging topic. Alternative channels seem offer personal bias. Go Kyle!
This is so great!!!
Anything y’all would do I would watch. The way you’re able to explain information and make it understandable is amazing. An energy channel would be amazing!
It is like having your own gas station with your own oil grid and your own oil refinery at home. Whoever can afford it , definitely worth it!!
wrong!!! its not even a comparison! oil is refined to make literally millions of byproducts from car tires to plastics for cable insulation, fuel for mining, construction, agriculture, transport... even launching rockets for internet, asphalt roads, aviation and tousands of other applications.
Getting ready to go with EcoFlow Ultras and ground mount panels because I can install them easily vs Tesla Powerwall 3 only being available through an installer.
You can force the powerwalls to charge by moving the slider then just before charging completes go into the utility rate plan and manually adjust export price and force grid export. Do this all day every day and make bank. Our electricity bill last month in UK was -£40.
Welcome to my world! You should come up to VT sometime, we're in the middle of building an entire neighborhood with solar and Powerwalls!
Would be fascinated seeing the story on that.
Is this part of a GMP project? I’m impressed with how much they have pushed things like micro grids and overall grid resilience. Other utilities (and state governments) should be paying attention. I wish NH was as far along as you guys are!
Yes
Yes
and
YES
That was indeed the inverter you identified on the side of the house. There is no reason not to charge in off peak hours when you are on a net metering system. Love the free power on my system, for the house and the car. So far, we are in the green by a long way with no power bill, just a monthly connection fee.
Yes please! I would love to see an energy channel! Panel warrantees are based on maintaining 80 percent of the label power so many manufacturer will sandbag the rating to ensure they achieve it long term. However, installers will usually put in an inverter that is less than the systems rated power to reduce clipping at low production times (morning/evening). Not sure what’s going on here.
Yea,that was pretty neat.
Kyle, I was surprised to hear you hadn’t dived into this energy cycle before, specifically because of how you’ve spoken in the past about grid powered, solar enhanced Megapack charging stations and similar. The home scenario is exactly the same just scaled down to the single family home level; solar PV system, Powerwall (or similar) and grid tied.
Out of Spec Energy, Definitely, You Nailed it Again Kyle
Thank You for All that you are doing for our Planet Earth.... Peace.. Shalom.. Salam.. Namaste 🙏🏻 😊 🌈 ✌ ☮ ❤
Yes!
I have an Enphase Micro-inverter setup on 2 houses.
First is 4.5kW Solar running for 11.5years and produced 65MWh, no storage.
Second is 12kW solar and 20kWh storage running for just 7 months and produced 10.4MWh.
I have a Chargepoint Home Flex hardwired and 48 amp capable so the Taycan can get 11kW.
Thank you Tesla for good product
Yes Out of Spec Solar would rock, just looking at 16KW system for our house near Vancouver BC for not only charging our EV's also net metering, backup power on outage etc.
You should consider making a video about Tesla Wall Connector Dynamic Power Management. Adding a power meter allows the wall connector to reduce power when the house is pulling a lot of power and allow peak power when home power draw is low. No one is talking about this. It saves thousands in service upgrades, and gives you peak charging.
So cool to see the integrations between products!
Tesla always nails that!
Yes. Yes. Yes. An alternative energy channel would be wonderful. On some days in Texas, alternative energy provides 90% of the energy to the Texas grid.
Lovely house. Brilliant installation. Got to video on Porsche 👍
Great video - We just got almost exactly the same setup (8.1KW system with 2 power walls all Tesla $37K total cost - 30% Federal Government Incentive). Most of our stuff is mounted on the south-facing side of the house, outside, directly next to the main panel.
While you can't really justify the system from a cost-savings perspective (at $150/month it would take 250+ months (21+ years) to amortize, people spend money on standby backup generators (like Generac), which cost between 5K for a partial backup and 20K for a whole house backup + installation cost. If you consider that, it does make fiscal sense. Add to that the 30% Federal Government incentive (which applies to the entire project (including power walls)), and it is a no-brainer.
+++ on an energy channel - it would be a neat way to bring the entire "solar-electrical revolution" together.
yes
Great video. Definitely should do an Energy channel!!! Th reason we didn't go with the Tesla Solar panels because they switched to one main inverter. We went with Tesla PW x3 and SunPower Equinox E20 327W system - 54 panels, with micro inverter on each panel. Our place have lost of shade. Also SunPower provide an architect signed solar generation plan. Planned generation was 11,400 kwh, actual 10.9 in 2022 and 11.2 in 2023. With these panels our ROI is about 17 years.
I highly recommend something similar to a keshee battey kit (13.4 kwh) for $2500 over the powerwall. I got those and they are excellent.
That was awesome Kyle and Thankyou Mr. Rob for allowing us to learn from you. that's exactly what I want to have my house set as for the same reasons Mr. Rob expressed.
I'm building my solar system as we speak in Southern Colorado.
My initial setup is 8kw of panels, ~15 kwh of battery, and an 18k PV/12k inverter. I will double my battery bank probably at the end of summer 2024, and also probably add another 4kw of panels for a total of 12k worth of panels.
Yes to out of spec energy! Tesla/EVs was my gateway drug, but now I'm a full-blown green energy nerd
For about a year my solar system has been online and I do not regret having done that for a minute.
I have a similar setup. 12 kW peak power and 28kWh of energy storage and I am also charging my EV. I am not familiar with the current prices in the US but $40 000 seems a little bit expensive to me. My system is based on Victron components and I spent about 24000€ for that.
Nice to see an tightly integrated system. I have a disparate one where nothing talks to nothing and it is a bit of a faff, but that's what you get when you go incremental (and don't want to pay Tesla prices on the energy stuff).
We added a Tesla Solar and powerwall system to an existing 4 year old solar system. The Tesla app enables us to monitor the old and new system in the Tesla app but I still have the app for the older system running and the two agree on output power and energy generation so no issue with the Tesla app power measurement. In the year we have had our powerwall there have been 16 recorded outages with the longest 45 minutes but most of the other outages were momentary dropouts which we would not even know about unless we were notified by the Tesla app because the switchover to battery is almost instantaneous. The Tesla backup delays the return to the grid for bout 5 minutes after the grid power is restored which is good because often the grid power is unstable when it first comes back on line.
1) wire outside home is better in case of fire n debug
2) charging from battery is better because u do not pay energy distribution cost. Basically there is lot of transmission loss from the grid.
I would suggest drain battery to 10-20% at night to charge and same way use battery to power up home during peak hours. Export max electricity during peak. Rest up charge battery or car
Fantastic video
Have invested in several go green systems at my home in Seattle. On a scale of 1-10 here’s how I rate them
Solar Panels 15 KW system - Rate 10. Silfab with Enphase microinverters; Very happy.
Advise getting large ststem to take care of your possible future electricity needs (I.e. EV, heat pump, electric range, etc.). Adding later is possible but you have to go through the permit process again and might not get as favorable a net metering contract in future. I didn’t get battery storage because I have a good net metering deal and I think our cars (like F150 ) will act as batteries in future though that requires about $5k of equipment too.
Hyundai Ioniq5- I rate 9.5 out of 10. Downgrade slightly because road trips slight anxiety. My son has Tesla Y which has had price decrease to level where I’d probably choose that and enjoy the Supercharger network for road trips (though all cars likely get to use it soon).
Home EV level 2 charger. Rate 9.5 because I wish wasn’t so expensive for electrical work. If you have a 240 in your garage, I’d start just using that if your car comes with a 240 home charger (Tesla does, Hyundai doesn’t).
Mitsubishi Heat Pump (without heat strips or gas furnace). Rate 9.5. I downgrade a little as they are expensive and I don’t think last quite as long as a high efficiency gas furnace. But I am able to make enough electricity with solar panels so feel good about environmental efforts.
Thanks for your interesting channel Kyle, I’ve learned a lot.
Great video! In order to use charge with solar with my Tesla is the Tesla Wall Charger required or would this work with any charger?
Definitely would be interested in an energy channel! I always thought that you should be integrating this into your CZcams videos. I remember the video where you showed the Tesla Powerwall that you had still boxed in your garage and was hoping at the time that you would show how it would be used (without solar) to flatten the load. Tesla has gone back and forth about allowing the purchase of the powerwall without installing solar. A solar installation just doesn't make sense for some houses and the powerwall has many advantages especially when the utility all allows you to sell back electricity at peak times. One issue that no one seems to talk about that I would like you to cover is dealing with roof repair and replacement once you have solar panels on the roof. This will happen and would like more information on how people deal with this.
Really really interested in this!!!
Pretty interesting. The way I look at the net metering thing, it may not be making HIM more green/as green as he could be, but it's helping OTHERS be more green, so it's still a net positive over all
That’s a dream garage! And Yes I would love to see more content like this. I’m thinking of adding solar panels and this is exactly what I would do minus the Porsche lol
It's correct to say Driving on Sunshine 😊
It is fantastic that you are constantly learning-there are others like Matt Ferrell that cover power very well-so dipping into this area could be helpful - but a full channel?
New Channel sounds like a great idea. Buying into home energy generation has scary prospect because of the high final cost numbers. $300 light bill seems better than a $40,000 solar install. Trading a loan payment for a light bill makes so much more sense when you realize that the final cost of solar is set and cost of electricity from the grid is not. Living in NC where new net metering will go into affect soon, I will be upgrading my system with battery backup and makes the purchase of a monsterous truck like the silverado ev and its 215kw battery more appealing to me. Not only as a vehicle, but as a means to go offgrid in the future using the teucks massive battery to get through the winter months without paying Duke Energy $28 a month just for the privilege of being connected to their grid and taking my solar for pennies in the summer
I have a 4.8kW Powerwall+ system with my MYP and love it. I plan to expand my system if Tesla does bidirectional charging on its other models.
Yes to OOSE!
Yes to the new channel
Wow, beautiful installation! 😀
How high is his ceiling???
I, too, plan my solarroof power to come inside the attic and then to the garage from a gable peak roof connection.
Cheers, Eric
I have a 7kW solar system (~40kWh per day) and two Powerwalls, with 2 EVs charging from it (a Tesla Model S and a Rivian R1T). I had to write my own software to make it possible - mixing a 2016 Tesla wall charger and an OpenEVSE. But it works great, and I’m in the process of adding automation based on weather forecasts - to prioritize charging the Powerwall from the grid at night if there’s not going to be much sun the next day.
Opt for REC panels, Enphase microinverters, Tesla Gateway-2, Tesla Powerwalls-2, and the Tesla Universal Wall Connector. The last three Tesla components are essential for accessing "Powershare" bidirectional charging.
Cheers guys
Same system here and 3 years in and it works amazing…Tesla doesn’t get enough credit!
Most definitely interested
Absolutely interested in out of spec energy
his 2 inverters are 7.6kw each. Great video!! I have a 6kw system with 2 power wall 2's installed last March.
The new Powerwall 3 are 13.5 kW each!
We have a Tesla Solar Roof and Powerwalls. I also have a BMW i3 REx. On a sunny mid-March day when we don't drive a vehicle at all, the solar offsets about 55% of our energy usage. Got it right after they built their solar tile plant in NY and got NY-made tiles. So far in March '24, solar only accounts for 28% of our energy. In February it was 21%. Only 12% in January. 11% in December 23. It was 26% in August '23, but the absolute amount of solar generation was much higher due to it being summer. But the A/C was also running high so it drew a lot of electricity from both the solar and the grid. Our best month recently was May '23, which was 38% solar.
Overall, our solar does offset some of our energy usage, but it really leaves a lot to be desired. We're nowhere close to being self-powered, even when we aren't driving. And if we ARE driving the i3, and charging it at home, that pulls down our solar offset significantly.
BTW, the 5 minute outages every month or so are standard. It's technically just a really quick light flicker, as either the inverter or the grid performs some kind of self-test, and runs off of the powerwall for 5 minutes. If you connect directly to the grid you wouldn't even notice those as outages at all.
I would recommend Powerwall to anyone - it is a good system - but I would not recommend solar roof. Solar panels will produce more energy per unit area, so just get those. Also, using a third-party EV with the Tesla system doesn't give us any kind of EV integration with the Tesla app. It's very much a walled garden, leaving our EVSE as just a generic load (but we can obviously see in the Tesla app graphs when the EVSE charges, as it forms the single biggest load spike on our usage graphs).
One thing to keep in mind: the guy in this video has a much bigger house than me. Assuming that your solar setup is giving you slightly more energy than you consume per unit area of panels or solar roof, then it stands to reason that the bigger your house, the higher % of your energy budget is going to be offset by solar. Therefore with a small house, you can expect a relatively small impact.
Thank you for the real-world results that you shared. I am curious, what is the rated output capacity of your solar roof?
Being in the Northeast on an average day we only get 6 hours of sun, when you factor in clouds, rain, snow, fog etc. if you lived in Arizona where they average over 10 hours of sun per day. They average way more sun per day and solar makes more electricity and more sense
@@jackylsmith8138I’m in NH and solar makes total sense at my house. We have 2 EV’s and almost all electric everything. 5 people in the house, a pool, etc. I don’t pay a bill. Ever. With the high utility rates in the northeast Solar makes up for any production losses due to geography. Also, our colder temps are more conducive to high yields. May is the best month for most of us in New England!
Is very neat. Battery and solar panel prices have plummeted over the last 12-24 mos too
Looks like a great system. The price is a head scratcher. I priced adding Powerwalls to my solar system and it was cost prohibitive at more than $30k added to my solar system cost.
Loved that! More - please!
Our friends in Hawaii run the America Savings Bank
The new Solar system keeps them running off the sun!
For free!!
Homes and Americans are starting to get it.
Wish I could do it in my rainy Vancouver condo… 😒
For sure add solar system or energy plants in general. Would be a awesome addition. I have diy a 11kw system I run 9 months out of the year mostly off grid. I run my model 3 performance on solar as much as possible. Living in Minnesota is tough from November to February to get enough solar power. It would be cool if u interviewed other youtube solar channels, Some are interested in evs also.
Solar panels are rated based on a standardised amount of light directly perpendicular to the panel at a temperature of 25 C. Depending on conditions and panel placement, actual production can exceed or fall short of the nameplate capacity. E.g. on a cold bright sunny day, panels can exceed their stated capacity.
These are the kinds of videos I want to see
In cool weather coming out from under clouds solar panels can routinely make 16-20% more than rated but just for a few minutes until the sunlight heats the panels.
We are installing a similar system but using Enphase (solar panels micro inverters, controller, and batteries). They can do everything the Tesla can, but costs less. Depending on your utility, they often pay more for your solar (peak hr) production than they charge for your night time (off peak) usage.
I have a Generac PWRCell system with Sense energy monitor. I charge our 2 Tesla’s from extra solar using TesSense.
Out of Spec Energy. Yes. Keeping the system off grid is tough, more battery or more solar for cloudy days.
I have the same excess power production bug on my system. I've had them come by and try to fix it. I gave up and the instant power rating is wrong, but the historical is correct.
I noticed the chimney on the roof- since Tesla uses string inverters, won’t the revolving shadow from the chimney greatly diminish the output of the panels? I assume, with a chimney feature, that micro inverters (such as Enphase) would have been a better choice than Tesla.
Very cool setup. I love the integration on the Tesla app. I am curious though, you mentioned net metering as same cost in as what goes out. Is that common? Our electric company pays pennies on exported energy. I eventually want a massive system what can run day to day without touching the grid except for cloudy days or outages. Also is the whole house (all circuits) connected through the Power walls? AC units as well? I would assume so since it can run the EVs. I think I know this next answer... Would this setup control a Non Tesla EV in the same manner? Absolute YES for OOSE!!
This is excellent! Excellent service to the society at large!
I'm very interested in energy storage/production. I'm in an area where solar, hydro, or a combined setup would be feasible. I would love to educate myself to the point where I can make it happen.
This is the way to go. We got our 11KW system installed two years ago. It is extremely empowering.
When the next generation batteries come out with 80+KWH it will be even better.
We just installed 3 Powerwalls and about 10KW of solar on our fence and some ground mount. We have a Model Y that is set to charge from soar.
Our home (near Nashville TN) is all electric, heat pump hot water, heat pump HVAC, condensing washer/dryer, with a Model Y and a Smart For Two ED (yes, all electric), and even a electric lawn mower. BTW We set our 'reserve' to 30%, and have no net metering. Our cost of electricity is low (think 11 to 14cents/kwh depending on how you want to calculate it). We are not considering the ROI, since we did some things that make no financial sense, but we wanted anyway.
We are using grid tie inverters, that will work with the powerwalls if the grid is down. (Inverters are APSystem Solar DS3-S) and our panels are oversized at 370W bifacials).
You're right though about the potential increased cost from using the batteries more vs selling back to the grid especially if his Utility has a minimum monthly charge. His power plan is quite unique though
The power is limited by panels, and further limited by inverter. Solar is very expensive in US compared to Australia as you have tariffs on cheap Chinese panels that work well. The panels are on the south side as that’s where the sun is, especially in winter. Mine face north as I am in Australia. East and west is okay however facing away from sun is not.
