Link to my new solar panel video! Part one: ua-cam.com/video/9YswyY1i-Us/v-deo.html part two: ua-cam.com/video/jeKHMe0kVbI/v-deo.html
Cool video. I use to install solar pool heaters in FL. If I remember right they were sunworks systems.
one of the best diy solar water heater diy video in youtube..very inspired...
this is my version..ua-cam.com/video/TKZBX2Zwu7I/v-deo.html
Nice job! But for extra heat in sunny days you could use a black tarp layed on the water surface instead of the wooden lid ;)
👍 Danke fürs Hochladen!
👍 Thanks for uploading!
👍 Very good and beautiful, thank you!
👍 Sehr gut und schön, danke!
That's some amazing work you did on that. Be interesting if you made another using plexi or glass on the light entry cover to make a comparison.
Thanks! No I have only made this one so fare. I choose glass because this glass has those pyramids on it, and when it gets hot (in case that would happen) plexi could melt. But maybe I'll try it in the future as an experiment.
@@TheDIYScienceGuy plexi glass isnt UV-proof. It becomes opaque after a few years.
I know, it's best to use polycarbonate.
Leuk project, zeker vandaag de dag met de gasprijzen.
A Fresnel lens might help amplify the sun energy in winter on certain metals.... but what if you mix or match metals? Say stainless sheet fused over copper sheet? One allowing for even heat distribution while the other allows for staying hotter longer? Just like the copper infused on bottom of stainless steel cookware
Nice work!! However, you should connect left top / right bottom to the water tube in order to prevent a "short cut" flow of water through the collector.
Thanks, I have already done that. 😉
The DIY Science Guy How frustrating to discover you had this rght the first time, and it wasn’t the ‘school boy error’ you thought it was!
Well that's the way we learn 😉
The sell a sealer for roofs that would do better. Actually the plumbing that you had at first would be better. Water follows the path of least resistance. If you had an inlet on one side and the outlet on the other, the resistance through all paths would be the same. The way you have it, water prefers following the first "rung of the ladder" and least prefers the furthest.
Did you drill holes in the long top and bottom pipes and simply insert and solder the cross pipes?
Yes I realized that later but it's ok for now. Yes I drilled the holes and than soldered the pipes in them. Thanks for the suggestions! 👍
Thank you for uploading. How does it perform in winter temperatures?
Thanks!! I don't know jet. It's still summer where I live ;) I will let you know in a future video.
I like this installation. I may be looking for this as part for a solar powered water distillation kit. Use for purifying dirty water to drinking water. As i understand the water is activily steaming on a hot day, the steam can be feed into a tube that goes into and underground tank where it condensates. Maybe i would like to put a steaming kettle (with parabolic sunreflector) in between for extra safety. So the hot water of this panel feeds into the hot kettle where it is put into extra hot steam, then goes into a cooling vessel. How much would it cost to make this?
Nice idea! I thing around $250,- if you make it yourself.
what is the name of that glass you showed ?? would like to make a solar water heater to pre heat my water before going to an oil fired hot water heat looking at a tankless hot water heater however in my area say too cold for them to be effective however my thouugh would be if I could pre heat the water before it would go to a tankless hot water heat may make it work better
Great job, congrats,, what kind of pump or motor are you using ?, or how do you get the water flowing?, sorry if i missed on the video.
Great video by the way, very inspiring, i´m seriously thinking on building my own following your steps.
Here is a link to the pump I used: banggood.com
banggood.app.link/NSqSGkm5K7
Nice design and well made i think with some little improvements it be perfect, how much would it cost to buy
Thanks! Have you seen this video of mine: ua-cam.com/video/9YswyY1i-Us/v-deo.html th3 the new panel costs $450,- in material.
Good video, how is it performing now? Also what type of glass did you use? Thinking of building one for my wood fired hot tub I’m building, less chopping.
Thanks! Well it's winter here so to prevent it from freezing I emptied it out. But in the summer it could keep my hot tub at a nice 30C 86F which saved me a lot of wood! I'm not sure how the glass is called. I bought it at my local glass store thingy place.
The DIY Science Guy 86*F that's not even warm! Better make something else. Perhaps some solar troughs.
nice video
Thanks again! ;)
The hottest thing I've come too figure out is roofing tin. You can lay a piece of black plastic in sun and a piece of roofing tin. The tin gets hotter. Painting it black with black bbq grill paint, not shiny...may help it too get hotter.
There use to be a fan that works with heat....not electric or power source. There was something involved with the properties of the metal used that made the blades turn. Getting heat to move from one place to other without power and making it useful too warm interiors and so on. Now...thinking about it.....stainless steel cookware stays hot a long time after you cook something, but aluminum cookware cools down in a hurry. Sheet copper I'm not sure about, but certain cookware has a lining of it on bottom to make a better even heat.
If it feels hot it does not immediately mean it's also hotter. It could also conduct heat better and therefore supply more heat to your hand.
very accurate plans for something like that I found on Avasva
Thanks!
Fuck off avasva
in the industrial refridgeration business we had inner finned copper tube and outer finned copper tubeing depending application just a thought ... available ? usefull ?
Do you have a link because I'm not familiar with what you mean.
@@TheDIYScienceGuy no link, it was my job. an increse in surface area in heat exchanger tubes u could look in maybe parts suply . i will look also
Does the chlorine in the tube affect the copper?
Any why duct tape and *then* aluminium tape, instead of just using aluminium tape to start with?
No it doesn't do much. Aluminium tape tears easily. Have you seen my new panel? Part one: ua-cam.com/video/9YswyY1i-Us/v-deo.html part two: ua-cam.com/video/jeKHMe0kVbI/v-deo.html
Hi, I'm wondering … Could you provide the test results or take another video to show how much temperature increase to your pool?
Thanks 😀
Hi, I will make an other video about it this year I hope (that I will have enough time), but it produces around 500 watt. Thanks!
How to connect the power of the solar just like your provide why they have a water
It makes hot water not electricity.
Next plan is to built a pump on it with a temperature regulator?
You can read my mind Rickieboy! 😉
So... What was the final temperature after testing longer?
Don't know jet, that last test was yesterday, so I hope that I can further test it the coming week.
How many Watt per square meter during a normal sunny day ?
About 500/750 Watt
I think there is a better solution for your solar heater. You should try to make housing with strong material for example you can make frame with metal tubes and bottom with metal sheet and weld all that together, the goal is to be sealed. The rest is the same as yours panel, copper tubes inside and glass on top. After that you should put valve on the panel so that you can connect the compressor from the fridge to draw air from panel and to make the vacuum inside. Such a panel would be much more efficient. Vacuum tubes for solar heater can be purchased but they are overpriced. What do you think of this idea?
That would make a bit more efficient, but a flat structure that could withstand the forces of a vacuum would be very heavy and expensive.
That would give you partial efficiency gain. If you would make it twice as big it would create much more energy at a lower price than when you vacuum it. And it needs less maintenance.
The beauty of this design is that it's simple. It is plenty efficient for his purposes, and adding vacuum pumps and enlarging it is not necessary.
....the only thing I would do differently is build it in a plywood box for durability. It adds a bit of weight, but could still be moved around.
Does anyone know what he is using to do the welding please x
Solder
how to use a bunsenburner :-)
It's a Teclu burner ;p LOL
@@TheDIYScienceGuy is love to know how you do your welding and what it is your using. Please would you let me know. It would be great if you had a video of it . Love your videos xx
Thanks! I'm soldering it not welding. I use soldering tin and flux for copper soldering. This guy explains the soldering technic very wel: ua-cam.com/video/JyVbjDsric4/v-deo.html good luck!
Why not put the pipes on the front? More surface area, and the sun would hit the pipe directly rather than having to heat it via conduction through solder? (Solder is way less efficient than copper in that regard)
Insulating the mounting points would improve efficiency. Heading the wood blocks and steel clamps is a waste
It's not a bad idea however, when the sun is at an angle, which it is most of the time, it would create a shadow which isn't perfect either. The wood and clamps are inside the box and only connected to the outside by a thin screw (there always have to be some compromises). The in and outlet indeed neet to be insulated which I did (and the rest of the hose) but not jet in the video because this was one of the first tests. But thanks for your input! 👍
@@TheDIYScienceGuy i was referring to insulating the copper from the clamps, not the clamps from the box.
Good point about shadows. Maybe a formed plate like
___/0\___ (upside down) would let the sun hit the pipe without shadows.
Yes _/0\_ would work the best and that's how the off the shelve ones do it but it's hard to make without machinery and I think the difference is marginal. The clamp and wood are inside the box so even if thay get hot that doesen't mater as long as that heat can not escape. The screw that's going outside is screwed in the wood and wood also insulates pretty well compared to steel.
Go to Avasva eco blog and learn how to do it.
