​@@electronicsNmoreSir, why don't you use flowing or stagnant water or a CPU cooling fan beneath the heat sink I hope that improvement could decrease the temperature by at least 20 - 25°C more. Anyways you did a great job by at least trying to conduct this experiment as I was longing for this since childhood. Thank you so much I hope you conduct future similar improvement experiments.

Great! That's about as much as anyone is going to squeeze out of that mini solar panel w/out an active cooling syst3m. I really appreciate your frequent monitoring.

@@brandonjohnson6645 I was thinking something similar... I built a 3 phase rectifying diode array that is rated for 600 amps/6000 volts and placed it inside of a sealed half gallon container full of mineral oil. Due to the super efficient cooling, I'm able to exceed the theoretical ratings to the extent that I can't get test equipment that will read that high. The voltage tested has been so high that the mineral oil has been used to suppress arcing between the leads... So immerse the aluminum heat sink in mineral oil in this solar panel experiment, then repeat it using a peltier device rated for about 5 volts in the same rig. The end goal is to see which is a more efficient method of passive energy generation. This could spawn a whole series of videos for an enterprising mind.

I have put some thought into it. I suspect that the biggest hurdles in scaling up would be optimization of lens orientation, light diffusion, and the implementation of adequate cooling. As you scale the size of the solar cell, the lens size and orientation changes. As the lens size increases, the need for cooling increases proportionally. The size and complexity of the cooling system also depends on the size of the panel and whether or not it is stationary or Sun tracking. Basically the platform has potential, but lacks easy implementation options. Large scale manufacturing would help to lower the difficulty of installation, but the cost would be prohibitive. Making modular systems with commercially-available parts could work, but then there is added cost in labor and materials beyond what a solar installation already requires. There is a tradeoff somewhere and then you get hit with the law of diminishing returns. For every extra dollar, resource, or unit of time/energy you put in, the extra returns are smaller than previous increases. This makes the system unlikely to be popular; at least until some brilliant chap sorts out a commercially-viable solution which bypasses a majority of the complexity and/or cost. TL;DR: Scaling this up would be a labor of love. Commercial implementations are possible, but not likely to be very practical. The cost and complexity outweigh the added benefit. Custom solutions will be difficult. God speed if you wish to try.

@yeah I'm John Assal Fresnel lenses maybe cheaper than solar panels but the sun moves and therefore so does the focus, so the panels would need to be mounted in a frame and track the sun, and that is definitely not cheap - especially as you would need one for each panel or pair of panels. I'm afraid that more panels is the appropriate solution to get more power, and/or watercooling them.

@ahaveland

@yeah I'm John Assal The subject was Fresnel lenses, they are flat by definition and only work well when rays are near perpendicular. A parabolic trough partially solves astigmatism in the azimuth axis, but as the incident angle gets further off-axis, the focus moves away from the target. Also, it would still need to track elevation, and the panels would be facing 180° from the sun. This is not so bad for oil filled pipes, but not for solar panels which need area and need to dump heat. Their capacity to generate also becomes saturated. All these ideas have been discussed and researched for over 50 years - if there was an easier, cheaper and more efficient way of doing things, then it would already have been done. Result - adding tracking is still more expensive than adding more panels especially when factoring in maintenance, and they offer no advantage in overcast skies because the light is diffuse and cannot be focused anyway!

Not cheaper by a long shot.

You're going to need a beam scatter, since the fresnell lens turns incoming light into a focal distance point, and that alone will coock the media of the cells (unfortunately) but with the propper fd and a diffuser employed, you might be able to concentrate the intense light into the shape of the pannel without it (the light) heating up the media, water won't cool the panel fast enough, but that's probably why solar city's tiles aren't that thick, because there's little to do to get more with an "appeal" aspect to solar panels on your roof. If you can work out the fd and the scatter pattern to less that 2" high, you got a good pannel idea for off the grid use. Awesome video! Love your enthusiasm 😊

As for liquid cooling: They even make generic 'stick on' water blocks that would work fine for this. For scavenging some extra work out of the fluid, you could use low-temp Sterling engines, but as they have so little torque, getting voltage out of them isn't too easy. You might be able to replace the flywheel in such a setup with a fan to get some air moving over the heat sink for 'free', but the pump is going to need power from the cells to run. As for how big a radiator would be required? with a .2 amp 12v fan and 120mm rad, it should be able to dissipate 80w-100w of heat from some off the cuff guesswork on my part. As concentrated photovoltaic systems benefit *greatly* from higher-quality cells, you'd want to use them to maximize the 'net' gain from the system. using liquid cooling allows you to use mirrors as well as lenses to get some pretty mind-boggling output out of the most expensive cells. At a certain point they'll just burn though.

I believe that solar panels get their energy from the ultra violet part of the light spectrum if your lens is made from plastic then you might get a better result with less magnification via a glass lens as I’m fairly sure that most plastics block out a lot more ultra violet light than glass.

I also thought using convex lens and Fresnel Lens to increase solar panel. However it is a hassle to set up them in the correct position. It is better just to buy more solar panel. The new solar panel product is half cell solar panel.

Exact same thing, but add a container of water under the bottomside of the heat sync? Can we get it cooler with "off grid" means? Cool vid

What about putting the F lens directly on the solar panel(s) and seeing how far away from 90º you can get from the sun, before losing output? Use those concentric rings to gather light from different angles and point it down onto the PV cells, ya know?

Would be very useful on a larger (house) scale. You could use water for cooling, then use the heated water for something else eg filling a hot water tank / central heating system.

I would say no. While you could theoretically increase the output, the loss in lifespan is so high, that it wouldn't be worth it. You are probably talking months, not years (lifespan.) Even with active cooling, the surface of the panel is going to be ridiculously high. There is also a lot of danger in Fresnel lenses.

Heat does NOT rise. Less dense materials rise. Most materials show decreasing density as temperature increases. That isnt the heat rising. Its the material. Heat simply flows to achieve equilibrium. No direction.

The fresnel lense is about 8x the area of the solar panel. Since the power developed with lense is 4x the panel alone, the system efficiency is about 50%. 8 solar panels in the same area of the fresnel lense would develop 2x the power at a lower temp at the panel

But solar panels are current devices? They have a maximum power point if you limit the current draw

Aluminium square tubes that are 8mm OD 6mm ID or 1mm wall using surgical rubber tubing to join ends so that the flow of water can go from top to bottom with a small circulation pump would cool a larger 200w panel with a Fresnel Lens. From a 200w panel you would normally get about 60% power or 120w without using anything else to get higher efficiency. If you use a Fresnel Lens & water cooling then perhaps you could get about 90% of 200w or 180w less 10w of power for the pump giving 170w which is still 85% of it's rated power.

interesting test. the heat sink would work better if you flipped the panel & heatsink so thr sink was pointing up & used a mirror underneath to aim light from the f, lens at it.

It's such low temperature that you could get away with prototyping in cardboard as it can take up to about 500 degrees.

I recon that water flowing over the panel would cool it down enough to allow for the wattage use of the said motor.

You wouldn't gain anything by adding a motor.

electronicsNmore that would depend power the motor consumed a extra power you got from cooling the solar panel

What if you placed a infrared filter in front of the freznel lens? Would not that reduce heating without reducing power too mouch?

Power would drop off bigtime. Thanks for watching!

is there a way to, somehow, tube airflow and improve cooling?

The heat sink used in this video worked fairly well, so the only other thing I'd do is water cool the heat sink. Thanks for watching!

If we use LED panel and magnigying glass may work well

Hi, I’m wondering if some sort of heat exchanger could be used to kill two birds with one stone. Cool the solar panel and charge a thermal battery?

Do you have a similar video with a spherical lense?

No, maybe in the future. :-)

Magnifiers and high lumens leds to charge at night would be a good experiment.

Did this ever get re-tried with water cooling?

At what height have u placed the fresnel lens above the solar cell.

High enough to ensure the entire mini solar panel had full concentrated sun exposure. Thanks for watching!

A fan on the coil solar driven might cool more like a computer cpu

where did u buy a fresnel lens? thx before *sorry for my bad english

The fins would cool substantially better if they run vertically instead of horizontally.

@@electronicsNmore possibly you could cut the heat sink in half with a hacksaw, and turn the halves 90 degrees? I've been really curious about this exact experiment, so I want to see it run with optimal execution to see if it can be effective enough to be worth it in a larger scale application. Next level after this would be heatpipe to a radiator in a water bath. Keep up the great content!

Has anyone taken a peltier module like is used on a wood stove fan and mounted them to a aluminum plate and laid it out in the sun light with a painted black plate on top. Hooked in series could get a new type of solar generation system. Even making floating solar barges could be a thing to slow ocean heating buy turning the heat into electrical current.

You work for free? I don't find it funny at all. The problem is, we live in a society where people are always looking for "hands outs", they think they're entitled to everything, and do nothing for others in return. My entire life I've helped others.

@@electronicsNmore what I thought is funny is that youtube is a platform where most of the people who create content receive no compensation for their work, youtube is basically a slave driver corporation, and you complain that you aren't getting payed in your video, also guilt tripping us isn't going to do anything, people know when they are being manipulated, and for me at least it's going to drive me away.

Won't that heat sync actually heat up in the sun. It would probably do better painted or covered, at least where the sun hits it.

It heats up, but also dissipates heat. Painting the heat sink is a bad idea because it would insulate the metal and make it harder to cool off. Thanks for watching!

Would the sink work better if The fins were vertical ?

@electronicsNmore

Harder to find those, but maybe a slight bit cooler because the heat can easily rise up and out.

What about water cooling? You could use a solar water pump to keep it cool.
