I wonder if the heating would be less with a load in the circuit? The multimeter measures amps and current, but how does that work if there's no load in the circuit? Wouldn't you need a load? Either way, there are cold places on the earth that get plenty of sun.

I had the same idea years ago. I tried this too. It didn't work in strong sun. Maybe it would work in low light conditions better. The first thing I learned using panels is that placement is most important. With the Fresnel lens maybe it will give you a better latitude in less than optimum conditions. I also thought of using a water bath to cool the panel. That does work but you cannot recirculate the water, you need to bleed off the hot or all you are doing is making a thermal heater.
I get the joke, but people in Antarctica (and the Arctic) actually *do* have an issue with cooling in the sense that those that have refrigerators have the temperature within them kept at a controlled level/range so that (for example) things don't freeze. :)
You could add a transparent IR blocking film. Depending on the type and quality it can block almost all IR (heat) rays from the sun and let through almost all of the rest of the solar rays.
For 4.5 x efficiency, you need to setup a magnifying lens, rack, and cooling device. Bravo!!! really smart, why don't you just set up 5 pieces of solar panels.
if you use a frensal lens on a pv-solar-thermal hybrid unit that heats water with energy lost as heat, it will cool the pv and stop its voltage from reducing
It would be good in Nordic countries which has low ambient temperatures half the year. There is not More light created in this experiment, the same amount of light but it is concentrated over the panel. Cool experiment.
Why not just use a solar panel as big as the lens? I am pretty sure that would be more efficient regarding electric output and it is certainly smaller, cooler. Probably also cheaper.
It'd be interesting to see how placing it on a passive heatsink might help. Being able to minimise the amount of silicon needed for a home array with heatsinks and lenses could be a great longterm investment.

@@electronicsNmore figured you'd notice, how hot is that spot? lots of ideas , how about using a radiator for thermal, they're putting together a solar thermal farm out west good idea. there's lots of ideas with the magnifier even magnifying the magnifier, if it helps would making a cone in between the panels and the magnifier might capture more.
So I had a shower thought about raising the output of solar panels with either a lens or mirrors or whatever, and obviously, there's a video on it. Absolutely brilliant! Thank you for making this and your other video with the cooling. So here's a follow-up thought: What if you were able to transfer the heat into a thermoelectric generator, rather than "loosing" it in a dispersing medium? Is that a possibility?
current thermoelectric generator tech has horribly low efficiency, converts 9% heat to energy at most, great idea but not worth while, better just warm some water with it in a heat exchanger and you put all the heat to use
Nice! I planned to do this test some day. Expecting those result. I was also thinking water cooled heat sink, like another commenter mentioned. Doing some mental math though, any setup will probably cost more plus take up more space than more solar panels, but maybe you could used the heated water for something.
you are losing efficiency, you rather just conver everything to heat and power a steam generator which in the correct scale is more efficient than solar panels and cheaper because you can use mirrors instead
The only worthwhile thing to do, would be to spray the panel with water every minute, or submerge the panel in a shallow pool of water. I have another idea for a future video. :-)
I raised the same question in seminar, but speaker avoided me saying it will burn little wire in system, so I said use wire according to that, finally he accepted that he never tried it

Is there a way to filter out some of the light (blue light for instance) that would help with keeping the solar panel cooler? Thanks for this research. I always wondered if using a large night security light could also be used to create more power using a Fresnel lens to offset the power loss by these power hungry night security lights. Anyone with knowledge please give me some feedback. Thanks.
You can buy blue light filters. I don't know what would happen. Maybe I'll try it. I made the video because I knew many people thought about trying the experiment. Thanks for watching!
The first time you read the current draw, you only change the rotary switch setting without switching the leads into the proper terminal. The second time you take a reading you do it properly.
What would be good is a way to use the energy focused by a lens or glass sphere without the need for a battery or solar panel. I imagine it must be possible to heat a body of water using focused light from a glass ball. Surely it would be possible to heat up copper that could transfer the heat to water or cooking equipment?
Nice! Thanks for the demonstration, mate! That theorical predicted results proves. It could be improve the experiment aplying a solar filter film in the range of infrared frequencies like passband filter to cut the hotests radiations and permits pass the light radiantions without affect the solar panel performance, theoretically. This experiment it was something i went to perform time ago, thanks for share. Regards
You dont have to try to maximize everything...just make 3 sets. back it off a little..so it wont damage the solar panels. as long as it stays above 4 Volts..it'll charge a 12v battery all day long for free. My lipo balance charger isnt exact...it just has to be above 12v input.

Run a PC or flat screen all day long or even charge cell phones. Just use a power converter for cigg litter..i use to charge or run my PC off of my truck (12v)
If you bring the panel toward the lens, you should find an optimal distance there the output is maximum, as the decrease of output due to less intensity is balanced by the increase of output due to decrease of heat, something like a bell shaped curve.
Try parabolic focus on panel combined with a solid state semi conductor generator (,Seebeck effect) to cool and use heat different to generate more power. Excellent work Thanks Shalom
what if you had water cooling it while the concentrated sun was on it? spray, mist, flow . . ??? The water would block some of the intensity, but not as much as the concentration provides. Would it cool enough to keep output high?
Obviously, to put a solar panel in water, it would need to lay flat. But then the suns rays wouldn't be perpendicular. Suppose we do lay them flat and submerged them in water? Then we used AND Fresnel lenses mirrors to reflect and magnify the sun rays perpendicularly to the panels? Then we automatically rotate and tilt the whole setup such that we get coverage the entire day? Have you ever seen that experiment?
Put a peltier device on the backside of the solar panel to act as a heat sink to keep the solar panel cooler. Also the peltier device will generate its own current to increase the over all energy output of your setup.

electronicsNmore You can get a very large Fresnel lens for free from an old rear-projection TV (ppl give them away on Craigslist). That should give you a huge solar panel equivalent area at zero cost. 👍🏼
Wonder if you had water in a container that the fresnel concentrated on brought to a boil - with the steam turning a tubine - then going through a cooling tube (like a still) but then somehow have it brought back into the original container (closed loop) to keep reboiling the same water - no water loss - without an explosion like a boiler tank explosion from excess pressure. Similar to the solar mirror concentrators inthe west...
Great experiment! Can you try using different filters to filter out different frequencies of light, for example an infrared filter? I'm wondering if filtering out a certain part of the light spectrum might allow the solar panel to operate at a lower temperature while maintaining 380mA.
Seen a number of vids on the subject, one a guy setup a parabolic reflector in a earthen pit under an array of collectors elevated about 10 ft. and he was cooking them! Read somewhere that it really shortens the lifespan of the collectors though with too much amplification. That would make for a good long-tern test as well.
@@electronicsNmore this would be interesting ...there seems to be several layers of diffusion material in an LCD TV...is one of them a Fresnel material and could it be used for this style of experiment?
solars panels are no use if you have efficiency loses inbetween. You'd be better taking some copper pipe, painting it black with candle wax sooth and making it give a few turns to maximize the surface the lense can heat and then use the steam to power one of those mini steam engines. Plus the advantage of solar farms like that is that mirrors are way cheaper than solar panels, and the system is overall just as efficient with the only disadvantage of a bit lower power density but space is way cheaper than solar panels, and the mirrors do not degrade over time nor need dangerous chemicals to produce.
@@WaschyNumber1 Condensation clouds from planes work and look the same as when i was a child in the 1970s. There are more airplanes in the sky these days and once you start to care about those could patterns, you will notice them more without trying. You can also see schematics for all planes that are approved for legal use and you will see that there is no space for giant tanks of chemicals other than the fuel and anyone can test the fuel that is being used... The notion of chem trails is just not a reasonable notion beyond a possible few black-ops missions with special planes, but those they would want to keep away from prying eyes and telescopes so you would not see those at all... In other words if you see those trails then it cannot be a black-ops mission because then they could be spotted and outed. And, regular planes could not hold enough chemicals to create clouds that size nor enough to have any effect on a populace below. It is simply condensation created by the plane moving through the atmosphere, now as it has been for decades.

I'm not sure what wavelength of light the solar panel uses but I think it's the infrared that causes it to heath up so if you get a infrared filter that is heat resistant & put it just in front of the panel would that stop the panel heating up but allow enough of the light the solar panel uses saving any sort of heat sinks etc? Just a thought would be nice to see what happens
I wonder if you could do some kind of either passive cooling system on the back like a heatsink and use the convection processto keep the air flowing over the heat sink. Or could you use a little bit of the power to run a small cooling fan over that heatsink enough that you still have a net increase in power but not damage the panel. I suspect ultimately it is simply more effective to just use more panels. But certainly an interesting experiment

You should be looking for the load that will result in maximum power output. You could do this using a variable resistor and calculating the power.
Voltage was too low. Next video will have water / heatsink cooling and USB power tests
Wonder if you had water in a container that the fresnel concentrated on brought to a boil - with the steam turning a tubine - then going through a cooling tube (like a still) but then somehow have it brought back into the original container (closed loop) to keep reboiling the same water - no water loss - without an explosion like a boiler tank explosion from excess pressure. Similar to the solar mirror concentrators inthe west...
use a mirror - and let smal lamounts of water stream over the panel with a transparent duct
Interesting Idea. Thanks for watching! Please share the video link.
Great experiment! Can you try using different filters to filter out different frequencies of light, for example an infrared filter? I'm wondering if filtering out a certain part of the light spectrum might allow the solar panel to operate at a lower temperature while maintaining 380mA.
Infrared filters block out too much visible light. Cooling is the only way to go.
I LOVE SCIENCE!!! LET'S BLOW SOMETHING UP! Haha.. I love building weird, fun stuff. I had a hydrogen powered lawn mower for awhile. Good fun.
I've been interested in this type of experiment for a long time. I have my Fresnel from a projection tv and a 200 watt solar panel. So ya nice job.
I need to find a few trashed LCD/LED big screen tv's. :-) Thanks for watching!
Seen a number of vids on the subject, one a guy setup a parabolic reflector in a earthen pit under an array of collectors elevated about 10 ft. and he was cooking them! Read somewhere that it really shortens the lifespan of the collectors though with too much amplification. That would make for a good long-tern test as well.
@@ThePreyMantas Clearly your not understanding the experiment.
@@electronicsNmore this would be interesting ...there seems to be several layers of diffusion material in an LCD TV...is one of them a Fresnel material and could it be used for this style of experiment?
@@mekuranda You can only find fresnel lens in older projection tv's
I wonder what the numbers would have been by changing the distance between panel and lens.
The lens was set at the best possible position for max power output. Thanks for watching!
solars panels are no use if you have efficiency loses inbetween. You'd be better taking some copper pipe, painting it black with candle wax sooth and making it give a few turns to maximize the surface the lense can heat and then use the steam to power one of those mini steam engines.
Plus the advantage of solar farms like that is that mirrors are way cheaper than solar panels, and the system is overall just as efficient with the only disadvantage of a bit lower power density but space is way cheaper than solar panels, and the mirrors do not degrade over time nor need dangerous chemicals to produce.
True, but if you can keep that solar panel fairly cool with using extra power, it would work well. Thanks for watching!
Try this in winter times with less sun light and this day overall this shit Chem trails clouds ect.
@@WaschyNumber1 Condensation clouds from planes work and look the same as when i was a child in the 1970s. There are more airplanes in the sky these days and once you start to care about those could patterns, you will notice them more without trying. You can also see schematics for all planes that are approved for legal use and you will see that there is no space for giant tanks of chemicals other than the fuel and anyone can test the fuel that is being used... The notion of chem trails is just not a reasonable notion beyond a possible few black-ops missions with special planes, but those they would want to keep away from prying eyes and telescopes so you would not see those at all... In other words if you see those trails then it cannot be a black-ops mission because then they could be spotted and outed. And, regular planes could not hold enough chemicals to create clouds that size nor enough to have any effect on a populace below. It is simply condensation created by the plane moving through the atmosphere, now as it has been for decades.
@@0ooTheMAXXoo0 you have no clue what you are taking about and the clouds don't look for me the same like in my younger times, I don't know how old you are, probably 16y in this case yes they would look similar but this days it's much worse times 1000000.

More Prof than you would ever need!
Cool
can u get fresnal lense from old tv?
So is it stronger or not? I’m not an expert on all the electronic jargon
What is the fire risk probability here? will it combust due to extreme heat?
Maybe melt the substrate, but no fire.
I'm not sure what wavelength of light the solar panel uses but I think it's the infrared that causes it to heath up so if you get a infrared filter that is heat resistant & put it just in front of the panel would that stop the panel heating up but allow enough of the light the solar panel uses saving any sort of heat sinks etc? Just a thought would be nice to see what happens
Infrared blocking filters are dark, so it would end up blocking too much visible light.
Great
What is the size of fresnel lens??
Will it destroy the pannel?
What happened if you used a lighting diffuser screen instead? It should increases the brightness. Would that not bring more power?
No good, it reduces intensity.
How did you get that fresnel lens? I need one for research at my university.
Not only heat lowers the voltage but the planet moving lol
Can’t you use this voltage and amps to power some robotic way to make this apparatus turn with the sun?
You mean a "solar tracker". Some of the solar panel's power output can be used, but you'll end up having much less power to use for other things.
I wonder if you could do some kind of either passive cooling system on the back like a heatsink and use the convection processto keep the air flowing over the heat sink. Or could you use a little bit of the power to run a small cooling fan over that heatsink enough that you still have a net increase in power but not damage the panel.
I suspect ultimately it is simply more effective to just use more panels.
But certainly an interesting experiment
Coming soon. :-)
Good
Random TH-cam recommendation led me here.
Clear and concise with units in both imperial and metric - thanks for that!
Interesting video with answer that I have wondered previously.
You got yourself a new sub!
Thanks for subscribing! I have to do both, I have viewers watching all over the world.
@@electronicsNmore Here France, be in restaurant, looking to your amazing development without sound, just looking , shared it already and at home I will look again with sound. 👍👍👍❤
Would you consider trying this experiment again with a peltier plate for cooling? Imam curious to know if it could be colored and still realize a performance increase.
I have a couple ideas planned for another video. Peltiers waste too much power.
What if you put a mini fan to help keep the panel cool, would that help bring the voltage up?
I'm thinking water or a large bonded heat sink.
That same Fresnel lens can be used for solar cooking.
Yes. Thanks for watching Chris!
amazing
Copper cooling fins on the back should lower the temp easy or just a fan
Watch the newer video, it shows cooling. :-)
Or increase the thickness of charcoal and put the silver deeper on bottom or vice versa would sure increase voltage because in high heat we neead more charcoal thickness to compensate for low contrast
