I was under the impression that large inverters have a definite lifespan and micro inverters can last much longer and work around shade.

Hello Martyna. Could you do a video on the different Certifications that a consumer would want to have on Solar Panels? For example: UL certifications for hail etc.

HOA's are UNCONSTITUTIONAL. You pay but you don't really own unless the mob gets their payment every month.

When I purchased my solar system in DFW, I was paying 5 cents/kWh + TDU for a net of around 9 cents/kWh. As of June 2024, that rate has increased to 11 cents/kWh + TDU for around 15 cents/kWh. That lengthens the payback period significantly. I'm currently on track for a 23 year payback but that will continue to decrease if the electric rates continue to increase, unless net metering (ignoring TDU) goes away and then the floor will fall out. You can't just multiply solar production with the electric rate unless your electric company pays the same rate for generation as consumption. No retail vendor in the DFW area offers that nor do I expect them to start. It's only going to get worse for solar payback as far as I can predict.

Good video. I got quotes from three solar companies where I live in the Pacific Northwest. Each proposed a different panel manufacturer, SILFAB, REC, and Q-Cell. I was also asking for a battery backup system and all three proposed Tesla Powerwalls. I also had personal recommendations from friends for two of the companies providing bids and the third was sent to me by Tesla. Ultimately I chose the outfit that proposed SILFAB. The panels were not the determining factor but rather the interaction with the sales rep and the effort he made to understand what I was actually asking them to build. The other two kept trying to tell me what they thought I wanted. It didn't hurt that SILFAB manufactures panels in Washington. You have put me at ease about SILFAB.

Interesting, but for me, don't care about the money. I want power all the time regardless of what the grid is or is not providing. Power security is the ROI for me.

It seems Tesla agrees with you but does the fact that the string inverter is built into the Power Wall 3 negate the advantage? Will users 10 yrs down the road need to replace the entire battery if the internal inverter fails? I suppose a 25 yr warranty with Tesla is a safer bet than most.

18 years solar owner, purchased best of best for time, SunPower 220W and after hail totalled my roof had solar removed. Considering not putting the old system back up because you can get panels with twice the wattage and only slightly larger panel. Also after 18 years microinverters have become king and shading is a lot larger problem in my residential neighborhood.

Great information. Batteries will explode when prices are less than 100 usd per kw/hour to the retail home customer. And that will happen in 2025.

Solar doesn’t work when the sun goes down, covered by ice or snow, or dark stormy days. If there is wind, none of what i mentioned is a factor.

Microwind turbines is a great way to supplement larger solar systems, giving the most power at times opposite to the solar panels.

I should have gone with Solartime. Too many problems to list here. I can say DO NOT buy from Aztec Renewable Energy.

I am new to your channel Question: what is the max solar system for a single PW3? In the past Tesla required you to buy a whole new system for expansion… my plan is to start with a 5 or 8kw system then add only panels to existing system in the future.

Could you explain a good TOU example? I do not wish to monitor credits from utility company. Would rather build a small enough system with battery to off set peak cost. Maybe also charge a little of the battery with off-peak grid rates.

Major cause of wind turbine failures is improper lubrication ( over lubrication )

Ya know what……. I have Enphase panels with micro inverters. I chose Enphase panels because they had the highest wind rating of any panel. The bottom line is to run a 2500 square foot house AND two electric cars …………$27.42 !!! That’s really all I care about.

FPL is still 1 for 1. They keep trying to change but have to pass during a election vote. They even try to re word it

Excellent summary.

Thank you for this. Most informative. I did not know that microinverters are not interchangeable. I always wanted a DIY kit or something close to that because as you've answered/stated who know who will be around in 5 years. My question for you or anyone else is....would I need optimizers if I'm using the Ecoflow Delta Pro Ultra? I plan on running the solar paneld in series and plugging it straight into the Ecoflow unit. My understanding is I would not need anything else? Thank you.

You explained to me why vendors go with one vs the other and where they charge, because we are in a business of making money. Before this solution I did not know what an inverter was. As an ecoflow customer Now I know if they would sell me inverters I would know what to choose. In which I would choose the String Inverter. Exchange it and peace of mind.

great Video,THANKS !

Hello. Can show the datasheet of the sma inverter? Have control the information of power about micro inverters and optimizers?

What she fails to mention is her system has No Expensive Batteries for Storage!. So when the Grid is down and the sun isn't out, she has No Power unless she has a generator backup!! Also, governments & utilities can not be counted on to keep paying you for back-feeding the grid! She is right about one thing though, solar panel on your roof is a bad idea!

Plsss why did the floor panels have a higher output than the south facing roof mounted panels even when they produced at the same time period of the day

No it will not because it has to re orient itself to catch the wind. If it were a vertical axis then it would catch the wind regardless of the direction. Just another example of a company that does not understand wind direction.

You did an excellent job! Keep keeping it real. Props

If you get less $ per kWh selling it to the power conglomerates than you pay per kWh, that is NOT Net Metering. Net Metering means the meter turns forward when you use electricity, and backward at the SAME RATE when you return electricity. The "net" result is you total you pay is: kWh Used - kWh Sent = kWh at regular rate. Anything else is not Net Metering.

The problem is, you produced that much…but did you get paid for your excess production? Without a 1:1 buyback or even a buyback at the lesser wholesale rate, you are giving that energy away for free. I have an 11.2kw system (36 panels) that covers just over 1/2 of our consumption. With a 1:1 buyback, which is no longer possible in my area, we used to get full credit and negative bills in the spring and fall and reduced bills in the summer. Now they cap the buyback to your total consumption for that billing cycle, and pay wholesale rates for excess. So if you produce 4000 kWh and consume 2000 your total credit will only be for 2000. Well that sounds like it adds up, but self consumption will likely not be the full 2000 kWh for the whole bill, they will pull from the grid at night. You will only self consume a portion of your production With a system that sized, there is no way that house is consuming all that production or being credited for excess at full retail rates of .17 cents. We get .10/kwh wholesale, pay .15 from the grid. If you are giving away power for free, you aren’t eating into your initial cost and thus not affecting your ROI timeline.

The question I would have is about the roof work. Mainly because roof work ain’t cheap.

What about 700-watt solar panels?

keep solar on the roof, but ground mount arrys are a waste of land , plant crops not pannels .

you are great

Hi Martyna, how about shingled panels? Does there any reliable shingled panels that can perform better compred to half-cut with optimizer? How about the cost comparison with half-cut+optimizer and shingled panels?

What if we dont have a garage? Where would we put the battery?

NOVEC in NOVA still pays 1:1 in credits but they do have a monthly service charge no matter what. They wipe the slate yearly - in January of course. My solution on my next install when I move South where 1:1 doesn't exist will be batteries so I need the power company as little as possible even at night. I've yet to sell credits, I cannot figure out what the heck to do with that.

Water damage would be a flood or water flowing up conduits! Not typical exposure.

Christmas light effect is still somewhat true if your installer parallels strings on roof. Tesla!

Wind is the totally effective solution to supplement residential power.

Thank you! Have a great day! România-UE

SCE only gives us $.07

Didn’t explain what the micro inverters do, Didn’t explain the bypass diodes, Didn’t get to the point, didn't describe the system size, didn’t organize your thoughts, repeated yourself. This should have been a string of videos. Gees

Wind turbines kill birds by the thousands !!

Can you redo this test by using string inverter with "shade fix" feature?

The cost of my power is only at .12/kwh. I’m not sure if it’s cost efficient for me to put money into solar panels. I’ll have to wait for government regulations to raise the price of my electricity to the .17/kwh for it to make sense. Well that’s if the price of solar panels don’t go up too.

@MrArtist7777. If you don't believe in wind power, but have installed over 2000 systems, what does that say about your integrity.

The government will start taxing the wind soon

What experience do people have when lightning strikes nearby? How difficult is each system type to repair with some lightning damage?

Enphase is the biggest name in the game! Not Tesla.

As you eluded, the biggest savings are realized from using the solar-generated power directly - at the time of generation. It looks like your system is significantly oversized - well beyond personal requirements. Would your return on investment have been significantly earlier had you went with only a system that was a small percentage over personal requirements? A higher rate of return over a smaller initial investment? Or were you looking at total return over the life of the system? More total energy produced and buy-back income after payoff?

What are your thoughts about solar tracking systems for ground mount systems? I own some stock in 1 such company, FTC Solar which is Austin TX, and I am also thinking in investing in another, Array Technologies . What are your thoughts about solar shingles? What sort of energy storage/battery systems have you looked at that are worth installing in homes? I own stock in Jinko Solar and in a number of other lesser known solar energy companies.
