What you are saying is .. the solar professional will size out a system. let’s say 8kwh he will use real world number and add panels at that level to reach 8 kWh? Correct? And not the marketed wattage sizing.
Yes the solar professionals size the system based on real world output. So you can rely on that. Hopefully you have a good solar sales professional. Thanks for watching.
Thanks.
Thank you for watching and commenting. Enjoy the summer.
Where does the 1.etc comes from?
It comes from data culled by the Govt. National Renewable Energy Labs. Thanks for watching.
Very helpful.
Glad you liked it. Thanks for watching
Excellent discussion Jon, thank you
Glad you enjoyed it.
Freight ships may not be able to use solar, but, with auxillary sails, they could cut down fuel use, there by saving fuel and money for actually not that great of an investment of having automated auxillary sails on the ships.
Yes some of these challenges may require radical new solutions. But there are a lot of smart folks who are thinking of solutions now and we will see them in the next decades. Thanks for watching and your comment.
I don’t think so.. Solar is booming And it makes more sense now than ever
😀 You did not see my video did you? Thats my exact conclusion - Solar is booming and there is no stopping it.
@@MySolarHomeUSA I did watch it.. I’m just saying that as I know solar is blowing up
Como se apaga 😮

what happens after 20 years from now when we have a billion solar panels that needs to be recycled ? As far as I know we don't have a good way to do that at least today. And how much minerals do we have available on earth to make solar panels ? Don't miss understand me, I got solar panels my self, and I really like it, but can we keep on making them in large scale over long time without having a problem later ?
You make an excellent point. Recycling Solar Panels is one of the fastest growing areas in the ancilliary solar sector. There are a no. of large companies creating facilities to recycle panels and get them back into the manufacturing cycle. The enormous growth potential is drawing huge pools of investment. I believe we should be in a much better place in another 20 years. Thanks for watching and commenting.
So what if you paint the roof white under the panel to reduce temperature and increase reflection for double sided panels?
Bifacial panels work better on ground mounts or flat roof ballasted mounts.. Rooftop bifacial performance is not great as the panels are flush against the roof and there is very little reflection back to the panels. Stick to residential panels for regular roofs. Thanks for watching.
what exact kind of inverter would I need for 40, 400W Q cells panels? (16,000 Watt output) Could you attach a link where I could purchase it?
You can contact Cooper Electric and ask for the Enphase IQ8+ Microinverters. Thanks for watching.
I have 6 Solid Sate Batteries and use a transfer switch and system monitor. Power off at noon and back on at 8 pm. Runs A/C too.
That is very impressive. What kind of Solid State Batteries are you using. And it would be nice if you could share pictures. My email is [email protected]
No, I don’t think so. Right now the industry ,technology of all products is changing, more offerings and better equipment so next year when the new equipment comes out, why would I buy last year‘s equipment even if it was cheap why ? not me. Most countries with Solar use the larger 450 to 600 W panels and equipment. And it’s coming in the next few years to us . see more change.
I agree using the latest tech is the best. In solar the tech does not change that fast and last years tech might still be the best this year as well. Re the 450 to 600 watt panels - those are actually commercial grade panels - the are much larger than the residential panels and not suitable for use on our roofs. The most efficient residential panel we have today is the REC 470. I expect we will see some more panels in that range next year. Thank you.
How do I contact for further assistance?

Excellent, thank you!
Glad you enjoyed it! Thank you for watching.
I have a House in Mexico and the problem is that the Grid power is such poor quality ( between 240 volts and 265 volts) I had to switch from a Old Sunnyboy to a New Fronius Primo that will still sell/push power into the grid up to 270 volts. What is the voltage range that the TPW3 will still connect to the local grid? Thank you for your information!
Hey Kevin, That is a difficult question to answer. Solar and Batteries are programmed to work with higher than 240 volts, but no one discloses the exact tolerance in specs. I am not sure if Tesla sells the Powerwall 3 in Mexico - but if they do, they will be able to answer the voltage question with authority. Alternatively, you can call Tesla in the US and try your luck. But be prepared for some time on the phone. Best of Luck. Jon
I am not going to install battery. Just want to install solar my roof. I have lot third party vendors in my area who install enphase micro inverter + q cell. But enphase doesnt install solar. On the other end Tesla directly install solar system but they use string inveter but they are well known company and would be there to support in future. These vendors not sure whether they will in business for more time or not. Then what will happen in case any support required. Can i directly call enphase. Should i go with tesla as my roof is east and west facing. I have requirment of 22 panels. I can install all of them in East side. But i can only install 10 panel in west side. Should i install panel in east and west both side or just east side is fine ?
@GauravJain-qc2ux You can work with either Tesla or a large nationwide solar installer - they are usually reliable. Doing panels on the East only is OK - only if its exactly east west. If you share your address on email I could check that for you. And let me know if you would like a quote for just an Enphase system. Email me at [email protected] Thanks for watching and your comment.
Gedankenexperiment....in an off grid scenario w/o solar and only a PW3, what happens if your whole home backup draws more than 48 amps? Extrapolation.... say we have a PW3 and go off grid while a Teala model Y is charging at 48 amps. Would energy simply flow from the PW3 to the Model Y through the backed up Tesla wall charger? Or does the PW3 somehow communicate to the charger to quit?
To your question about the Powerwall 3 charging the CyberTruck (Congratulations !!!). Yes if you are out of home and your Powerwall 3 is on whole home backup mode - and that is the current configuration as far as I know, then it will start charging the Truck and go kaput in a couple of hours. Re Powerwall 3 working with Enphase - Tesla did tell me that they are working on launching an AC couple version towards the end of the year. I would make sure your solar installer actually has an AC coupled Tesla Powerwall 3. BIG CAVEAT - if you do Powerwall 3 with Enphase, you are wasting a lot of money. Thats because the Powerwall 3 has an inverter to take care of the panels and the battery. Now with Enphase the Tesla solar panel inverter will remain idle, unused and you would have paid for it. Either go all the way Enphase or all the way Tesla is my advise. I personally think its not going to be too big a difference in energy output as long as you have a couple of big arrays. Keep me in the loop and send a picture with you and the CyberTruck to [email protected] Thanks
Hey Jon...Picking up my 9 PW3 tomorrow!!!! (Cybertruck). Still doing all the maths. Will send you info soon. 1. I've seen several sources and one of my quotes say PW3 has 150 LRA. I see 185 LRA as you said. Why the difference? Are there different versions? 2. We talked before about PW3 NOT being capable of AC coupling (micro inverters). And others say the same. But sonething changed recently. My Tesla guy said it is possible now. And that is what PES quoted me....REC + micro + PW3. But why? My guess would be shading or snow covered panels? In Florida with minimal shading, I would think the advantage of micro inverter effiency would be less than the lower cost of DC coupled strings without conversion losses. Probably fewer boxes on my wall as well .... Talk soon.
Hey Drew, Apologies. I thought I had replied to this earlier. I presume congratulations are due for your new Cyber Truck. Congratulations. In Florida with a single or two array solar panel system the Tesla Powerwall 3 will do as well or better than Enphase Microinverters. With the cost advantage, Powerwall 3 would the route to go for you. Re the AC coupled Powerwall 3, I am not sure if it has been launched. Until I see some actual installs or if your installer has confirmed in writing that you will get an AC coupled version, I would be careful. Best and do email me once you are ready to see some numbers. [email protected]

I say this with respect. The comparison should be one Powerwall-3 against 3 IQ5P batteries.
I thought about that and I chose the smaller battery to keep the pricing similar. In terms of capability, the difference between a 10 kw and a 13.5 kwh Tesla would be about similar to the difference between a 13.5 kwh Tesla vs a 15 kwh Enphase. The excess power you get from the 3 batteries is not worth the trouble - as you really cant run those high power devices anyway with either 1 Tesla or 2 or even 3 Enphase 5P's. Thank you very much for watching.
@@MySolarHomeUSA But I thought that the 13.5kwh is the usable capacity, whereas for Enphase 5P, 80% usable capacity will be 4kwh. Hence, there is 8kwh usable capacity for the 10kwh. Therefore, a better comparison should be 3 Enphase (12kwh usable capacity, assuming 80% DOD) and one Tesla Powerwall.
@@1982757 The usable capacity of the Tesla Powerwall 3 is 13.5 kwh and the usable capacity of 2 Enphase 5P batteries is 10 kwh. The big boys give the usable capacity upfront. You don't have to do the 80% calculation. Thank you.
No! A Tesla scam!? I just can’t believe… That anyone still thinks they do anything else but scam.
Tesla is now all about getting solar commoditized and to lower prices as much as possible. That is putting downward pressure on other competitors and that is a good thing. The Solar Shingles are a disaster and should be discontinued IMHO. Thanks for watching.
Great analysis!!
Thank you very much. Appreciate you watching and commenting.
Thank You. Great info
I always thought "backup mode" capability was linked to the invertor and not the battery, what feature of the battery makes it backup mode capable, is it related to the discharge capacity?
Backup Mode capability depends on the availability of a Grid Interconnection device that allows the battery and the solar panels to be islanded during a power outage. This prevents the battery from electrocuting an utility worker on a pole outside. In a consumption mode or non backup mode install ,the battery only works during regular grid availability. On grid failure, the battery shuts down since there is no Interconnection device. Such installs are cheaper and thus favored by installers looking for more margins. As long as you installer gives you the option, you decide what works for you. For many folks in CA, the non backup mode is much cheaper and may be preferable. You just dont want to pay backup prices for non backup mode. Thank you for watching.
@@MySolarHomeUSA makes sense, and thank you for making these helpful videos
@@qudizzle1 You are most welcome. Thank you for watching.
I would look elsewhere if a solar company doesn't mandate battery backup with their installs.
Fortunately, most solar companies offer the option of solar panels with batteries. In states like California, this is mandatory since net metering is not available. However, in other states where net metering is available, batteries might not be essential. They only provide power during an outage, so areas with relatively rare power failures might not benefit as much from having a battery.
Great video, thank you
Glad you liked it! Thanks for watching.
5:06 Why is it not 13.5*16 ==> 216 kWh instead of the 165 kWh you stated?
Hello Vishal, You got me. That is an error and the max capacity should be 216 kwh. I have also heard that the Powerwall3 now has has an AC coupled version - but I have to confirm it. Thanks for watching and keeping me on my toes. Best Jon

every hse with solar needs a battery full stop no ifs no buts
I wish batteries were more affordable. I would whole heartedly agree with you then. Thank you for watching and commenting.
At the end you said "keep Tesla at a distance." Again, I'm in Florida, no shade, super South roof, perfect East/West roof also. And getting 9 Powerwalls (Cybertruck).
The new Powerwall 3 is a much better option now from Tesla. Pricing is excellent the 6 MPPT Inverter has better performance. When looking at Solar + Battery, the Tesla Powerwall 3 will be a top choice along with Enphase 5P batteries and their MicroInverters.
Thanks. Do any or all of these pannels work the the PW3 built in inverter? I think you said in anither video that Tesla pannels are Q Cell? You already answered one if my ither questions on anither vudeo. PW 3 Sucks? You siad PW3 can take different roof sections as separate strings. At Tesla website when trying to configure/order, why do they say pannels are not compatible with metal roof? I have metal roof. Not really standing seam. More like metal sheets overlapping with screws between them.
Hi Drew, All solar panels are compatible with the Powerwall 3. However when you buy from Tesla - they only have some specific panels and they are mostly from QCell. A metal sheet overlapping roof construction is tricky but do able. It depends on the distance between your rafters and their size. If they are 16-18 inches apart and they are 2 by 8 or larger you are good. Anything further apart would require an architect to have a look. My installer has done metal roofs like yours. Best Jon

Thank you for a GREAT explanation. 1. I have a great South roof and also excellent East and West. Should I put all pannels on facing South for efficiency, or put maybe put some facing East for morning generation, and sone facing West for PM generation (Peak rates). 2. I'm pretty much Tesla Guy. want PowerWall 3. Given the scenario above, would PW3 treat South, East and West facing panels as separate strings? 3. Got a quote from a company for an Enphase micro inverter array tied into a PowerWall 3. Is that even possible? I have read that PW 3 does not work with micro inverter system. THANKS!!!!! PS Im in Florida. No shade. Extra Credit: FL has standard Net Metering. Old philosophy had people trying to get Max array possible with NO battery. New philosophy seems to be people getting smaller arrays with more battery. Thoughts? I'm gonna have 10 Powerwalls next week!!!! ( Cybertruck+ 1 Powerwall)
1. Max out your South facing roof before the E and W roofs. The South roof gets energy through the entire day early morning to late evening. A South facing roof will always generate more energy than an E or W roof. 2. Yes they would be separate strings. And depending on how many panels are there on the South roof, that might end up being two strings as well. 3. Powerwall 3 with Enphase - not possible as on date as the Powerwall 3 is DC coupled and acts as the inverter for the panels as well as the inveter for the battery. So the quote must be for the Powerwall Plus and not the 3. I have a lot of customers in Florida. Your best bet is to maximize panels. Batteries will only give you backup power during an outage. If you dont have power outages - a battery will pretty much sit and do nothing. It wont reduce your electric bill since you dont have TOU billing in Florida. Congratulations on the CyberTruck. Share the quotes you have with me - send them to [email protected] I will most likely be able to offer you a better deal - I have established relationships with local installers for many years now. Thanks for watching and commenting. Jon
@@MySolarHomeUSA Thanks Jon. I will reach out. We do have TOU options with Duke Energy in Florida. Flat rate is about .15 /kWH. Under TOU, super off peak is .10. Evening peak is about .18, and other times .16.

great job. Just what I wanted. Thank you.
Thank you very much. Please do let me know if you are looking for any other videos that I could work on next.
Quite a good summary. Usually I find all sorts of problems with these sorts of videos but yours did a great job. I would recommend a somewhat different panel and charge controller configuration, but that's pretty much it. For the panel and charge controller configuration, don't use a parallel combiner at all. Parallel combiners such as the ones depicted in the video are actually fire hazards. Instead, use TWO Victron 150/35 charge controllers, each with one string of three panels going into it (well, assuming the string VOC is < 150V anyway). In addition, I would install a combiner box for each string (two combiner boxes, total).. .even though you aren't combining anything. The reasons for doing this are as follows: * You want at least two charge controllers for redundancy. If something breaks, you don't want to be left with now solar at all. * The lower amps from each charge controller makes wiring a whole lot easier. * The use of a combiner box both gives you expansion options later on and also gives you a convenient disconnect (the breaker in the combiner box) as well as fusing and a surge protection. So its good to have combiner boxes (two in this case) even if there is only one string going into each one. You already have some battery redundancy, which is great... a lot of people forget that but it is critical. The only thing left is the inverter. For the inverter: * I'd recommend a minimum of two inverters, for the same reason. Gives you redundancy in case you blow one up. But you can also do some cool things with two inverters, such as split the loads that might involve surges from all the other loads which just run regular house-hold non-inductive devices. This way the surges won't stress the other devices or the other inverter. * Consider a Victron Multiplus-II 48V. They come in a 3kW and 5kW model. Unfortunately only a single phase output but that's the way the cookie crumbles. The reason is the low idle power (about 12W for the 3000W version) and strong robustness. So like one of those plus one "junk" inverter, or just go straight to two multplus-II's. Low idle consumption is worth its weight in gold. -Matt
Thank you very much. Your recommendations are spot on and in my future videos I will surely incorporate those suggestions. And thank you for those kind words - I try hard to make sure I give good information and it is good to get validation from an expert practitioner. Happy Memorial Day.

I just purchased a new home at Georgetown,Texas and it's been only 6 months. Pedernal electric is our only Electric provider in my area. My house is under full sun and not surrounded by any trees.My usage is around 140-150 KwH during Jan,Feb'24 with my bill as $140-$150 while in the other months the usages are around 500-700KwH with my electricity bill ranging from $70 - $100 . I want to go solar but will it be a good option now. If yes,then which company will be the best providing solar panels and inverters like REC or Enphase, so that my monthly fixed payment is within $100 always. Would appreciate your kind understanding and guidance.Thank You!
Hi Biswanath, thanks for reaching out. I have responded to you by email. Best Jon.
very helpful video. Am in last phases of working out issues raised from site survey of my property. My spec is Panasonic EVPV400HK solar panels on garage with IQ8M microinverters. Originally spec'd IQ10T Enphase battery as backup but installers say issues with communication with this product and lack of space on wall next to main panel on main house is leading them to recommend PW3 with the built in inverter OR PW3 with A/C coupling (IQ8M micro). My question is whether you feel the new inverter in the PW3 with 6 MPPT for 6 arrays would be sufficient for 32 panels on a gable roof garage?
Hi Ray, Yes the PW3 will work very well with the 32 panel Panasonic panels. And why are you going with the Panasonic panels. Panasnonic has stopped manfucaturing panels and are now being supplied by REC. I think it is safer to buy REC panels direct. Who knows if Panasonic decides to exit. And, How much are you paying for the project? Email me details - I am usually able to do better than most vendors in the market because I have long relationships with the top installers in the country. And dont worry if you have a signed contract - since nothing is installed - you can cancel and the solar company will not come after you. (its an industry practice). Best Jon - my email is [email protected]
Jon, you didn't mention that Solaredge optimizers can be fairly easily bypassed. That means, the panels can revert to basic DC output.
I am not aware of this. Perhaps you can share more details on my email [email protected] Thanks for sharing.
FYI ... your website appears to be down as of 5/9/24.
