This is old technology, we in the UK built these 4 mtr panels in 1972. Our panels were made of copper sheet and had 15 mm copper pipe soldered to the copper sheet. They worked very well under glass until the Thermomax tubes came along. These tubes are now very low price and provide all your hot water requirements !
Hello... A year later, you'll need to remind yourself of this. Question: If this was practiced in the seventies, and you remember it, did you read Papanek's Design For The Real World? This isn't in it, but is in a similar vein. I'm 59, UK resident and come yearly to Kerala. Love seeing how the people here sort problems. I'm curious as to what readers thought of his book at the time. I read it in the mid-eighties and still love it. If you never read it, sorry.
I was thinking of something like this to give me hot water for my workshop., water supplied by the rain, filtered and then heated and stored in a hot water tank for use. Very informative video, thanks for sharing.
He man, you are so great handkrafter and i like your form for steel forming verry well, you think before working this is wunderful. Kind wishes from Germany
1 suggestion as i watch . Use better sealants. Maybe the self sealing butyl rubber for new home window flashing . That stuff stays soft in hot weather . High temperature RED engine sealants would work great also .
Link to the 2nd solar panel video: th-cam.com/video/jeKHMe0kVbI/w-d-xo.html Link to the 3th solar panel video: th-cam.com/video/DIk2mcJ7NHs/w-d-xo.html Link to the 4th solar panel video: th-cam.com/video/XtP4ypvRxz0/w-d-xo.html
Because copper is much more expensive and the efficiency would only be a small bit higher, because the water removes the heat so much faster out of the panel than it can radiate out of it.
Really nice execution, but so much work involved! I think it would be very interesting to compare this type of construction with something using more off the shelf parts like omega style heat transfer plates intended for in-floor radiant heat loops. Those transfer plates in 4 foot lengths are about $2-3 USD in 100ft quantities. To me that seems pretty cheap compared to the time to make your own.
@@keithedwards9953 above the prototype level, would be better off building a more robust and easier method of creating the panels. The pros use a roller system similar to seamless gutters.
That's a lot of work and materials that is unnecessary. But I'm glad I watched . As I am planning a new diy channel. I believe the insulation is a huge plus .
Just a thought but when two different metals such as copper and aluminum are in direct contact it causes galvanic corrosion. You could use the thermal paste that goes between a cpu and its heatsink. If would increase your heat transfer and act as a dielectric preventing contact between the metalsm
@@merchantmareed It happens even dry. When I was a pipefitter we had to use dielectric couplings when attaching pipes of different metals on even on air lines.
Two thin alu sheets. Gently bent edges and solder both sheets around perimeter leaving a void in the middle. Solder pipes in opposite corners. Paint one side matt black. Plug in hoses. Fill internal cavity with water/antifreeze. Instal in EPS insulated box. Use plastic (Polythene - same as for greenhouse) sheet to cover front... you can use two layers with cavity for better insulation. This could also work with alu-plastic composite, Alu sheet at the front and plastic backing. But in my area alu sheet comes cheaper than whatever plastic. Steel is another alternative, but increased weight and corrosion must be addressed. Much less labour. Much cheaper. Greater heat exchange area. But it will be heavier.
Good Lord bruw, use termoconductive paste in between the Allum and copper also don’t forget to sand both pipe and plate contact areas for maximum effect. Your welcome also thanks this is proof of concept on another idea that’s in the makings.🎉
Could have used an aluminum rod to press the pipe seat in one pass, plus use aluminum tube as the pipe to then weld braze the pipe to the aluminum sheet for full thermal bond. But you have it working and looks great.
When doing your 3 passes through the grove making clamp instead of lifting it out after each pass and feeding it through for the second and third just feed it back the opposite way then back again. Staying within the runners for all 3 passes
Photovoltaic / Solar Thermal Technician here: change the title what you built is a solar collector aka solar thermal collector not solar panel that converts solar energy to electricity. a tree can also be called solar collector when you think about it. i've built collectors from scratch. a lazy mans quick solar collector is also using a commercial grade garden hose. paint your collector black, yes makes a difference, i know that even without painting it still gets hot but been proven hotter if black and doesn't cause glare. i still give you a thumbs up.
You could make the housing out of wood, trespa (High Pressure Laminate-plate), some other plastic or ask someone to bend the aluminum for you like I did, the rest is DIY. Hope it helps!
Awesome project. I want to make my own Solar panels but it seems it is not easy. I hope there is an easier and cheaper way 🤭✌️ good luck always for you 🙏
If it gets hot enough, you can either use peltiers or Stirling engines to get a little electricity for the system and as long as you have a drop from height in the system you can also use a water turbine as well. It's not much electricity 10w but that's still enough to add extra charge to a system.
I think the temperature of the panel (not higher than 30c) is not hot enough to be useful for a peltier or a sterling engine. And the water doesn't drop because it is a closed loop. But good thinking! 👍
@@TheDIYScienceGuy well the Stirling would still work at that temperature but it's cold side would have to be in the building or something because it works through temperature difference. It starts working depending on the efficiency of the design at a 2 degrees C positive and 2 degrees C negative difference per side which means during summer it would work and winter it would work but it would be awful during evened out temperatures.
You should consider checking out Tech Connections page.. he has a formula/method for creating a thermal paste for extremely cheap and it would conduct better than your silicon.
Nice work. If the unit will not be used at mains water pressure, perhaps you can dispense with the copper pipe and use the silicone to seal the tube made from the two halves of aluminium? Connecting pipes will be required that can be made the same way. This eliminates thermal transfer resistance between pipe and plates. Perhaps you can just use two sheets of aluminium with spacers and sealing at the edges and bypass the piping aspect altogether? Another thought is if its possible to heat both sides at once with insulated sheets as reflectors? \ There there is the option of a linear parabolic dish focused on the pipe. You guys really started the creative juices going!
My "projects" at home are proof of concept, and/or utilitarian. When I do work on a customers site, I do finish work. My wife saw a customers house after I was done adding new circuits for pin lights, wall outlets, etc. It was at that moment she realized I could do beautiful work, not just the perpetually unfinished construction zone style I had subjected her to for 20 years. She turned and gave me that look, the one that could strip the heat shielding off the space shuttle. I am caulking baseboards in the room additions as we speak.
And you should pre-cut that chip before you start bending and I think you can bend from both ends and work it out like that little bit different construction but the same process with less things do on it more efficient and faster to assemble
If the ambient temperature doesnt come less than 5 degree celciuos in all seasons the evacuated glass tube heat collectors are the best for domestic water heating systems.
очень красивая получилась безделушка. Прежде чем делать надо было физику подучить. Вот на вскидку несколько ошибок: 1.Алюминий с медью образуют гальвано пару, не зависимо от наличия электролита. 2. узкая трубка с большим количеством поворотов создаст хгачительное сопротивление для движения воды. 3. поверхность пластин без чернения будет отражать значительную часть энергии в космос. 4. большая часть тепла не будет передаваться на трубку из-за малой площади соприкосновения с пластинами. Часть площади просто не будет передавать тепло на трубку. Самое главное, что все эти проблемы устранимы, достаточно просчитать по фоомулам.
.. grappig....ik maakte ca. 40 jaar geleden ook zulke panelen......wel met een houten bak.....we hadden 4 bakken van 150x100cm ( als ik het mij goed herinner)....en maakte met een warmtewisselaar van koperen pijp in de zomer een vat van 1m3 water tot 65 graden. De boer waar we de (test) installatie voor bouwde kon z'n ogen niet geloven! Dit was begin 1980 en toen nog wat bijzonders......
Nice project! I was wondering about how you prevent corrosion of the metals. Copper in direct contact with aluminium corrodes. Is the silicone layer enough to prevent that?
Impressive attention to detail. Why bother with so many small segments though? Seems like it would have been way easier to use a full sheet along the front or back and only small channels to clamp the copper tubing
Excellent build. With solar panel prices what they are why not just heat with electricity? With (8) 275 rated panels 4s2p , a disconnect and a 2000w 120vac water tank element ( in the lower tank position) you have a safe self regulating water heating system with no worries about leaks ,freezing etc. Over temp is controlled by a proper thermal DC switch.
You want rigid and water-tight? Weld it...it'd be less effort than what you did. You're very clever ! I'm sure you could design and build a roller-jig to impress the copper-pipe groove just by turning a wheel that rolls the sheet aluminum through.

I thought you meant how I sealed the joints of the aluminum housing. Indeed the bending is not very DIY but you can always pay someone to do that for you.
Interested in the calculating of laminar flow and turbulent flow, where did you guys find the information to calculate? And thanks for posting all these awesome videos! VERY COOL and informative. THANKS!
Have you heard of using black !/2" pipe coils in a wooden box covered in glass? Paint the wood black on the inside and build high enough that you can get 3 or 4 coils inside the box. works very well and very cheap. Get much better results than this rig will. Just an observation.
Excellent work, you have done many well thought out technical details, the silicone for maximum transfer was a very good idea. Congratulations. You have my suscription and my like.
Super easy huh!

Why not use copper plates and solder the plates to the tubes that should be more efficent.
Because copper is much more expensive and the efficiency would only be a small bit higher, because the water removes the heat so much faster out of the panel than it can radiate out of it.
