To get maximum watts from pv panel we need to match the resistance of the panel, (320W/33V=9.6A)(33V/9,6A=3.47 Ohms) to the resistance of the heating element(24 Ohms). 24 Ohms/3.47=@ 7 panels in series. 7x33V per panel in series= 231V. Be careful, probably not a safe voltage to work with. Find an element with lower Ohms and use fewer panels in sereis. David Poz has an excellent video and spreadsheet to find the correct combination of series/parallel panels and resistance heating element.
Thank you for trying to help & educate everyone !! Even one lesser solar panel alone seems to offer a great opportunity of, 134° F hot water or hot sand and only for a $100 !!? Are there any dangers to running one(or two) solar panel(s) indoors with element(s) 24/7 ?
I love this type of content as I lack imagination but when I see it and demonstrate it I come out looking like a genius, so I really need to hang out with smarter people. My question is does it matter which wire positive or negative goes in the stove top coil?
I’d use three of those panels in series, but even better is 2 parallel sets of three panels. Keep in mind that voltage and current output can get dangerous when wiring solar panels together. The noodles will cook in warm water with two panels in series, but will take longer.
Not sure if it’s commonplace in solar but this is what hybrid automotive tech has been doing for ages. Electric power steering, variable A/C compressors to names a few.
The electric coil elements are considered really inefficient given the amount of heat escaping outside the pot. It would be interesting to see a head to head with the that electric coil setup vs an induction plate that heats only the pot! Also as others have said, testing with insulating the electric coil setup so much less heat is escaping could be great.
Nice test. For power outages, I have stuff that microwaves in 2 to 3 minutes at 1,000 watts. Using battery and inverter of course, but can always recharge the battery with solar.
Why not comeup with a heatpump? solar cooker? Could be 300% efficient(uses 1/3 power, to produce same heat of a resistance heater), using same amount of solar power from panels 🤔. Could also make a dessert or cool cans of soda on the side. Definitely not going to fry a thing, but could heat water and most liquids efficiently. For those wanting to fry things, there is always the solar tube cooker, preventing loss from the light to electric conversion, not even needing a solar panel🤯. Just some 💭.❤👍
I'm more keen to the idea of _combining_ a traditional solar oven/cooker with a bifacial solar panel (with active reflection) driven heating element inside. The solar oven/cooker provides insulation and the direct all around heating, while the solar panel inputs some direct conductive heating to the pot (in my case, I would probably use nichrome wire wrapped around the pot). Since I make my own vacuum insulated panels, and would make a double pane top (bottom glass, top acrylic with a half inch or so of space in between), I could get it to cook well even in winter on the coldest of days. Not very motivated to do so though, because our property has so little consistent sun. Just too many dang trees around.
Series usually keeps the current the same but that is when you are using the full capability of the panels. In this case we were well under the amount of current each panel could produce so that falls back to the V = IR relationship so as the voltages doubles we also double the current.
Not the fastest, but it WILL work, in case of an emergency. I think It would be faster to light a fire, and boil the water that way. Plus you keep warm. You can warm up water at night, with a fire. I say only in an emergency.

No
I love all the math you do in these videos. Would be curious about using an induction cooktop since it's so much more efficient.
Another very good video! Maybe add some insulation to keep the losses low.
That would have made a HUGE difference. Thanks for the feedback and support 👍
Felt like I was right back in Heat Transfer and Fluid Flow class in the Navy lol great video man 👍
Thanks!
I starved to death just waiting for the noodles to be done.
😂

Best and most interesting DIY information I've found. Great teacher! Thanks for your gift of knowledge!
Thanks so much for the support 🙌
Tim pool vibes 😂
Good Evening ! Way cool. I'd like to see a solar shower set up PLEASE. Thank You. TAKE CARE..
That sounds like a fun project, thanks for the feedback!
Did you like that flir camera and do you think it's clear? Does it show the ambient peak highs and lows too so people can understand scale?

Nope, the wires can be reversed and will work exactly the same way.
i would love to see a heater setup based on this.
I’d use three of those panels in series, but even better is 2 parallel sets of three panels. Keep in mind that voltage and current output can get dangerous when wiring solar panels together.
The noodles will cook in warm water with two panels in series, but will take longer.
Thank you!!! I almost understand solar electrical math now.
Nice video. Have you considered using a DC-DC boost converter? I wonder if the efficiency would be better and end up with cooked ramen sooner😉😀

Can't beat that from an efficiency perspective. 👍

You make your own vacuum insulated panels? What for?
You did a great job explaining the Ohm's Law section of the video. Good job!
Thanks!
since the panels are for 24v setup why not wire them in parallel to increase the amps?
v=ir. resistance is fixed so only way to increase amps is to increase voltage
@dalegawne5286 it is why it's important to increase wire size to reduce loss
Sorry what type of splices did you use on the wire to the hot plate? Thanks Richard
Those are WAGO 221-2401 (Inline Splices) geni.us/G0BW

How did the current increase in series? Shouldn't it be the same as 1 panel?
Series usually keeps the current the same but that is when you are using the full capability of the panels. In this case we were well under the amount of current each panel could produce so that falls back to the V = IR relationship so as the voltages doubles we also double the current.
@@everydaysolar silly me. Thanks
It might be worth it to search for a lower resistance heating element.
Some tweaks might include a water purifier.
Fun project

What an interesting and different video.
Thanks for the feedback!
I came for the solar. I stayed for the math.
😂
Why not just use female spade terminals instead of hacking up the burner to use wagos?
Pretty large spades, you could get a cooktop socket and wire it up.
Spoiler alert: Starving Amazon guy stops by and eats the noodles.

Now you can make a sand battery to heat a small area
sand battery part 2?
(As I'm sure you know) A submersible heater core would be more efficient without making it more complicated :)
Please compare to solar radiation oven parabolic dish
1 l? How many gallons is that
3.8 liters per gallon
Isn't solar providing D.C. power while a stove runs on A.C.
I would rather a link to a solar calculator that tells me what parts I need NOT one that wants to send me a quote
What brand of Ramen? Add Chinese and eggs please
let's just hope nobody wants ramen noodles anywhere outside the hours of 1130am-1230pm, sunny days only.
Simple solar cooker with aluminium foil is faster than this
No can do getting dumber everyday then again solar not for everyone
21st century cave man trying to boil water simply?? Some twigs/ sticks/Bic lighter, more simple to make fire to boil water.
