Lovely! Awesome video. I can't wait to get started with my own solar system as soon as I move into the new house. I already got some Victron stuff laying around ;-)
Fancy seeing you here!

wo bleiben deine todesverachtenden videos :D
Looking forward to hearing about it! Would love to join team blue too some day 🤑
Stay creative and I will see you next time!!
The amount of humor mixed in with all that electronics talk, I do manage to "learn" so much more! 😂
that one professor of mine who sneaked in memes into his slides was the most engaging and entertaining for me. so yeah, totally works for me aswell =)
Had me at ''...my wallet agrees vigorously...'
Nice system. One thing to note - panels shoved on a flat roof obviously do alot less well in direct sun but actually do really well in cloud and rain as the sun is diffused though the cloud to give a general light from above. Most people don't actually really need the 1pm peak power but they do need the non peak cloudy power at all other times so this is a legit strategy if trying to power loads in your house all day every day. Also - and this is the main benefit - saves a ton of hassle and money on mounting hardware and is super DIY friendly. Just my tip to any wannabe flat roof DIYers forget brainstorming how to angle them - shove them all up plug them all in in 1 day and enjoy the power.
Cool, thanks. Any recommandations on a "stand-off" for parallel lying modules? Are there any benefits for passive cooling through that or something similar?
@@MatureFister Maybe not an ansvear to Your question, but my father made a dual system where the old system is based on copper pipes and blackened aluminium sheets, which is for hotwater and central heater supplement only (that one is mounted on a woodenrack on the wall in the south), then the idea is to use the electric panels for what is described in this video, including if the size of the system allows it, hooking up a heatpump, if it does not, one can get away with just a small panel and say a 12 or 24V pump and it will be enough to power up a woodfired centralhater from spring to autumn even here this far up in the north, it has worked for almost 30 years now on my father farmhouse so i think it does prove the concept.
Flat panel layout is most effective in tropical/equatorial region where the sun is not tilted much every month
@@sihamhamda47 It is not just about angle. Like OP indicated, this is effective even in non-equatorial regions, if your region is cloudy often. I tested this in the winter, when sun was covered and tilted a lot - flat mounting provided almost twice generation of the one angled to sun behind the clouds.
@@esuil Ah yes, I learning more about this now. Just starting to learn about solar power and it's thing to consider after found many, many news about switching to net zero and renewable power recently
I learned more in this video than I did in many other videos about solar
For future reference: butyl-tape is extremely useful stuff for sealing. It remains flexible, and you can knead it like play-doh. It's used in boats/marine applications to keep salt water out of screws that go through a deck, windows sealed etc. Also very cheap!
Its like ducttape 2.0 - and an excellent "cover" for small electronics that have an LED you don't want to see :)
hell yeah more solar stuff
Love the Stonghold Crusader references :)
they suprrised me with every one and I loved them all as I spent so long in that game
I always forget how good this channel is. I scroll past videos all the time because I think "too smart for me to even understand" However this is something I can grasp. I just forget the videos are hilarious half the time.
Marco, Nicely done. First major installation was 15 years ago - 2KW solar, 7KW Outback Solar inverters / MPP charger controller, and 2.2K AH Rolls Starette Pb batteries (before LiFePo was an option). Time to replace the batteries.
This guy could talk about paint drying and I’d watch it
Goodjob Marco! We love your videos because when we watch it fools us into thinking we could do the same :)
Nice fireworks display - great to see the neighbours are supportive of your efforts :)
All thread rod is so damn useful. I use stainless and normal rod all the time for projects and keep a stock of it handy. Combine it with nuts, washers, flange plates, and split ring hangers, and you really have a solution as versatile as duct tape.
SUPER nicely done! Congrats on your regular harvest and imprisonment of so many angry blue pixies!
Your videos never fail to entertain and I always learn a bunch of things at the same time. Thanks!
In Australia the DC string cut off has to be mounted on the roof. Originally they were next to the inverter but this proved dangerous for the fire brigade so the regulations changed...
7:33: bwahahahaha, couldn't keep that one in! You had me blurting out in laughter. Love the way you mix in your dry humour. Really makes my day. Well done! :)
Its cool that you did it all yourself and filmed everything at the end
Marco Reps: 0.7ppm is BAD, SAVE YOUR LIVES
also Marco: magnet is perfectly good when you sensing 230VAC
I liked the "irresponsible clowns messing with solar panels" Stable Diffusion images.
Nice... look forward to the next installment, and as you reminded me I need a clamp meter I bought one with your ref code 🙂
I love the Stronghold references sprinkled throughout this video. Pitch needed indeed.
Very brave of you to make a bunch of holes in the roof.
Hats off for that.
I'd be extremely cautious.. probably would not make any holes at all if possible.
So excited to finally get this video, super happy to see how things have gone, even if not entirely to plan!
Keep up the great work!
your passion with your projects inspires me every time
How can a german engineer be this funny
Hi I'm a flat roofer and figured I should mention something. I can't tell for certain just looking at this video, but I'm guessing your current roof is sbs modified bitumen or app modified bitumen, and the ashpalt you're melting and "patching" with is oxidized asphalt. Mixing different asphalts will be problematic as adhesion usually is sub optimal, I work with SBS mod-bit and we can only make temporary patches on APP mod-bit or Oxidized asphalt roofs as the chemicals will repel eachother after some time and the patch will simply not last. I'm worried you'll run into the same issue if in fact you used a different asphalt mix compared to the roof. You already said it's an experiment and obviously it's a diy solution, just figured I should tell you to be prepared to patch the penetrations again in a year or so, or atleast inspect it on a yearly basis as it most likely would spring a leak in a few years.
Vielen Dank für deine vielen wirklich guten Videos.
Dein Humor liegt genau auf meiner Wellenlänge.
Stronghold! I loved that game!
Something I was taught is that in winter, during particularly cold but sunny days, solar panels can actually output _more_ than their rated voltage due to the cold increasing their efficiency. This can damage the inverter. So maybe upsize your system a bit if you live somewhere where that might be a concern.
Great video. Looking forward to the next installment. Thanks.
Always a treat to watch! Post more often!
I love the tweezers and roof work. 10/10
Great job ! the learning curve is the best part of doing it yourself ! Great video! I did my own 9k system and I learned things watching you !🎉
I loved this video! So insightful and helpful. Please do more. Thank you.
Remember, utility companies love solar power - so long as it's *their* solar power. They don't want you generating your own; they want you to buy theirs.
Amazing video, you are extremely knowledgeable and funny at the same time. Thank you!
Einfach original deutsch mit den guten Birkenstock schlappen👍
I hope that one day someone cares about me as much a Marco cares about his PPMs
Great video with great commentary. Thanks.
I am so glad your neighbors had a firework show for you to celebrate the successful competition of your solar install. lol
That was a blast! Much enjoyed this. Thank you.
The pitch could have been used as a thread locker too and like the modern loctite product you release it by heating it. Very handy stuff
love your channel, solid engineering in a joking manner
informative, intrataning and it made me chuckle few times. Nice Video Marco
This really puts into perspective all the engineering we did on the mounting systems when I worked at SolarCity.
Love this vid thx
Congratulations! Looks very nice. Once again your humor is second to none! 😂❤
"I chose this path, no complaining now..." hits hard
Those stronghold references were awesome
Loving it, keep them coming
the narration is priceless as usual. 😄 And quality content as always.
I envy your skills, that stuff looks crisp!
Thank you for sharing!
Really nicely done fantastic and interesting project
hooray! i've been waiting for this video! 😄
Great video Marco, here in the Netherlands there is at least one provider that has per hour pricing. I hope Germany will follow for you.
There are two here that have that
Spare batteries gratefully recieved for solar shed workshop project :D
Ich find deine Videos immer echt klasse .... weiter so .... *thumbs up
Nice! 3-4 years is very ok payback time for DIY solar system. Usually payback time is 10-15 years without DIY.
You could have used a magnetic field paper to get a more accurate/less likely to fall off solution to finding the beams.
Best regards from Sweden.
I have a small cabin without electricity.
Like you, I have a small plant but only for 12V, and as you say, the daylight is not enough during the dark season.
Desperately looking for a good solution.
Nice I want more solar videos
This is EPIC!
Probably my favourite little series you've posted along side the hunt for ppms. I'd love for you to go into more detail on the efficiencies of the inverter and all the data logging you have going on in the background. It's a shame you didn't open up the inverter before installing it, interested to see what makes it tick in comparison to my aliexpress micro inverter which kills it's own mosfets once a year.
The sarcasm in this video is so funny
A very Stronghold heavy episode. Subscribed
Cool. Video. I love your Awesome sense of humour. :)
Very interresting. Thanks
Nice work
Yes, the video I've been waiting for while my Victron inverter works on lead acid while I wait for my lifepo4 rack battery :)
Very entertaining! xD Good job.
was not expecting the stronghold reference😂 nice one
Great job!
I am also in the middle of doing some PV action myself. However, I don't have the luxury of a garage surface to work with. So I chose a high performance foldable panel to put on my south facing balcony and sneak the output directly into my living room in an Anker 757 Powerhouse. Classic island PV system, I will try to power my AV receiver or maybe the entire TV setup exclusively on that.
In winter I can reduce the number of powered devices and plug the 1.2kWh station into the wall for a 1kw addition if needed. It is pass-through capable with
Very cool!
I love those solar electrons being liberated so much they form plasma arcs
Never thought your electricity price was so high ! Looks like shutting down your nuke wasn’t the best idea 😅
Its more Putins fault then nukes. When this video was filemd they were still running
For new contracts it is 32 ct/kWh now. Still quite expensive but the prices are coming down.
@@DerVersteherPlus That’s good news ! Also nice to see how low carbon your electricity is 🙏
Watching from kenya
Love it 👍
Awesome. Im mossing the black rubber gloves. Bring them back
You're way too good at everything you do. 😲
thank you so much for your slow ass video editing skills, absolutely hilarious and even with the mistakes you did a hell of a job. :). also thanks for the welectron tips, that's some great kit.
Very entertaining thanks!
Danke!
Nice video
this was nice. 🤗
Very nice
thanks so much reps. i was not aware of some things you highlighted here, especially that those sok have the capability to manage the inverter. always a pleasure to watch
as for your welectron code - i very much still hope to use it one day. to get a bmi869s. and maybe some other probes or accessories and stuff. however unfortunately had to prioritize. and instead got some probe master probes (which cannot buy from welectron the custom lengths). and for the clamp meter got the cheap but infamous uni-t ut210e instead of anything more expensive.
next time though, i really do hope to get the 869s. if not saving up for unreleased oscilloscopes... or psus... or another 34401a.... or a fume extractor. damn
so yes! your economization strategies i admire. very good set of budgetary choices there
Marco, at least you did it, my way. From Australia all the best. Winter is coming back here soon. Autumn is proving me 5 kW out of 10 KW an hour.
Coooooool. Nice job
There are fixtures accessories for these , no need invent anything special LOL 😅😅😅 , with your solution that will fly easy away in windy weather.
Yeah, the red tape involved to install a grid tie solar installation in Germany is mind boggling. The power company's even managed to get you for tax evasion if you put your power in the grid without proper permits and income tax. The 4 big energy company's who pretty much rule the EU got us here. In Spain is even a planed tax on solar panels, so it could be worse. XD
It's actually not THAT bad anymore, there were a lot of changes this year. Up to 10kw is pretty easy now afaik
A lot of this got changed during the last year. Just some examples:
-VAT is now 0% for PV components.
-Up to 30kWp no income tax for the profits and no registration as business necessary. (Liebhaberei)
-No VAT tax declaration, if you choose the Kleinunternehmerregelung (small business regulation).
-No more limits for delivery to the grid (70% rule was canceled)
-Higher compensation for the energy delivered to the grid.
-No building permit required for normal roof-top PV systems (this is not new, but still worth mentioning)
Grid tied PV systems have to be registered at the Marktstammdatenregister and with the grid operator. The grid operator has strict time limits on how long the processing of the application can take.
@@fkiesel9442 we need the same shit in france I can't believe we're so far beyond in terms of regulations
Nice!
So lucky you were able to DIY install that. Cant legally DIY that in Australia, even off grid. (I tried off grid and was told to remove it).
Actually, we are not allowed to change light switches or power points like many other countries either.
Marco seems to love inventing the wheel.. haha :)
Lol, love it!
Your humour and knowledge are fantastic and all the whilst you're dispelling the myth Germans can't be funny. Well done!
I can tell you from experience that even low frequency sine wave inverters are not immune to RFI emissions. I have had to go to Great Lengths adding mix 31 ferrite chokes to all the wiring going in and out of my inverter to get radio interference down to an acceptable level so I could listen to the HF bands on shortwave.
man you know a lot when it comes to electronics like most of the stuff you do seems like magic to me but maybe try and not re invent the wheel when it comes to house stuff lol altho i guess im in aus were solar is widely adopted so we have our install procedures all worked out already
but still good to see people getting out and keeping the diy mentality alive while still staying safe
Looking forward to seeing what you get out of those east-west panels. They look higher up than your garage panels - perhaps that will help in the darker months?
For the rack construction I think I would have welded it together, but you would have to remove some paint in strategic locations.
