Yes smatah herms.

Can cheap Sungrow inverter also solve the same shade problem? My installer keep promoting to get Solaredge and optimiser which is $3000 more expensive

hahahahaha the future. The companies no this is going to be the future. Sun Tax will end up in every state and it'll be the norm.

Good afternoon Sir. Dear Sir please can you give me a chance I want to work with your company. I’m working here in Japan with solar company if you give me a chance it will be great pleasure and more blessing for me and my family in Jesus name. Amen 🙏

Hey is there any vacancy for Installer or technician?

That was a real blessing to me.

Solar panels aren’t a source of energy

Solar output will be low when the sun is low on the horizon like mornings and afternoons. If your grid had battery storage you could store that extra power you get and use it at night that is the solution.

Which among sungrow string inverter and enphase IQ8p would you recommend if cost is not a constraint? I am looking for a system with topcon 560 watts bifacial solar panel.

Bullshite, proven by the Fact that all power bills have gone up. You and the government keep lying about renewables being cheaper, that is a lie, proven by the Fact that power bills keep going up. Prove otherwise or apologize to the citizens.

Top job NRG! Love your work! 👌

EV snake oil.

So the government can stop you from charging your EV car at the government's will.

Why would you want to learn from someone who is also still learning?

It sounds too big. A 6.6kw rooftop solar would have been adequate with the battery.

Why not panels = inverter?

And if you had an 8 kW inverter with the 8 kW of panels, you would get even MORE energy. So, what’s the point again of oversizing the panels to the inverter? This video surely doesn’t support it as the same logic used here would say to get a larger inverter to capture also the peak that is clipped.

Hilo sir I'm Solar Pv System Installation Technician I have 2 years experience 2 years experience in Saudi Arabia please me I no job this time

Hi sir I'm Solar Pv System Installation Technician I have 2 years experience solar Pv System in Saudi Arabia please solar job help me sir

I was a little confused because the video mentions that a Fronius string inverter can handle shading, and micro cracks etc... but really the inverter isn't managing any of that, right? Isn't it the technology employed in the panels themselves that determine the voltage and current output by the string? Great video though: nice confirmation that the micro inverter marketing is mostly BS. I'd much prefer a string inverter in an easily accessible point.

I wonder if one could drill down further into what caused the difference in unshaded production? What would the results have been with a string inverter with very low idle consumption, like a Victron?

The catch being, you better have enough sun light that hits your house. Roof built facing the opposite way? You’re screwed!

Is there a maximum number of micro inverters you can connect i series?

Its normal, i have done this on circle K car wash machine for years

Newer panels with bypass diodes make a big difference in helping string inverter setups NOT suffer like old-style panels, right?

Had a system with one of these installed last September. Unless this is an old video and I have mixed something up, this is hardly early access?

That was a huge 'micro' crack 😂

I was told the same thing about a shaded panel affecting the whole string just yesterday by an installation company. I thought at the time that it sounded ridiculous, because why would anyone put up with solar if that was the case? Those massive strings you see in farmers' fields would come unstuck with the slightest bit of mud on them. I'm glad my hunch was right and you've done the experiments to prove it. I don't have to shell out for the micro-inverters now which should save a significant amount on the installation, and reduce points of failure in the panels themselves. Thanks!

If it works, it works 👍

Did you ever make the video on using the string inverter with panels in parallel ?

Can you test two inverters, example SMA and Fronius string inverter on same panel set???? That would be cool test to show difference in shadowing controll in string and how MPPT controlls voltage and current!! Even if second inverter would be cheap chinese like growatt or similar. Nobody has done that!! 10 -12 perc panels (about 410w), there is difference in line controll in mppt. Depence who has make the string inverter and software.

@nrgsolar-nationalrenewable4401Are the modules on the Fronius string connected to each other in series or parallel?

I am solar installation technician I have installed all type sites please any opportunity refer me .

What’s the procedure for connecting via Ethernet? I try LAN on mine but i can’t connect. WLAN works but my connection is poor and i sometimes lose signal

It's all good, you can't go wrong with fronius. You'd have just as much success with SMA too probably. Those are the only 2 I trust (and Victron for more off grid kinda stuff).

Iam Shailendra kanaujiya From India ihave 6yeras experience solar engineer me joining Australia so plz gide me

Nice to see an intelligent, practical test of solar equipment - very well done. Could you test our political parties in the same way - especially the cricket bat test??? - just kidding - it would be like plaiting fog!

Thank you for your video; nice to see some actual numbers. Any reason to believe snow would change your conclusions?

Doing the math, there is no reason at all to have micro inverters nor DC optimizers.

So in conclusion, we don't need optimisers or microinverters?

Very very interesting experimentation & testing 👌👍

Hi, my name is Mohd Umair . I am from India . I am looking for a job in Australia as a solar installer and currently working in TATA POWER as a solar installer. Do you have any opening for fresher or intermediate?

Dont try and sound smart nobody cares

Thanks for recording and publishing your results. It calls into question the Marketing claims of many Solar Manufacturers.

"promosm" 😌

Thanks for the testing! I also tested shading panels, and the halfcut panel properly shaded WILL NOT DIE, and will not lower the performance of the whole string. Can anyone explain what happens on the panel level? The current should be halved on half covered panel, but it does not.

Are these videos for tik tok?

the guy at the truck at 13:08 was like: the fuck? hahahah

2 years later and there doesn't seem to be the follow up video, shame. I really wanted to see that. I keep swinging back and forth between 2 string inverter/2 string with some optimizers and full microinverters. Thanks to this and the video that led me here, I can now see through the marketing BS but as I will have panels on an East and South facing roof, I still need to decide which option will produce the most power whilst taking into account the cost for each solution. I've only just started learning about this stuff so with another few hours of surfing I might start leaning in one direction but for now, I'm standing here scratching my chin unsure which way to go. The East facing side (6 panels) only gets sun early in the morning when the south facing side (18 panels) is shaded. After 10am they both get sun but by 4pm the East side is shaded again. My biggest concern is that one side could pull the other down when it's shaded and this would happen at each end of the day. I've been quoted for a 2 string inverter without any optimizers but he's now suggested adding these for the 6 panels on the East side but then the inverter comes into play. It's currently quoted as 8kwh but with both sides shaded a lot, will the inverter be able to produce anything outside of the 6 hour window? Probably the wrong place to post this, should probably find a forum but seeing as I'm here, any advice?

You are right and very wrong. Solar PV and a heatpump together cost you $15k plus for whereas a solar water heating system is about $5.5k . We supply and install all 3 and nothing is better bangs for bucks than a solar water heating. See your channel is more and more about spending lots of money rather than best ROI which maybe good for your customer base (ie solar PV installers) but I feel is misleading the general public
