  • This is a fantastic video.

    Commercial Solar Panels are Expensive!

    Your Only Option is to Build Your own Solar Panels

    There is an Engineer from Chicago that explains it All

    You can find his web site by Searching Google for...

    "Top DIY Solar Panels"

    Go for the First Result (Ignore The Advertisements)

  • one word: COOL! =)

  • Направи следния опит: Постави фотоволтаичния панел в магнитно поле, произвеждано от самия панел! Или магнитно поле с постоянен магнит. Покажи ми какви са резултатите!

  • You should produce hybrid solar panels which create electricity AND hot water (by cooling the panel). I had that idea for years...

    It is definitely doable! Thanks for this video!

  • One panel points to the south, the other one to the north ;-)

  • very cool and significant experiment. congrats.

  • question, because of the higher optical density water relative to air and the higher index of refraction of water relative to air wouldn't there be some inverse effects? Thanks again for the great video by the way!

  • I must admit, I had not thought about solar panels getting less efficient as the sun heats them up ... very clever.

  • Good Observation Dan, cool video, thanks., I like the way you do stuff, "Very Real" & still put the message across, Nice 1 Dan...

    Thom in Scotland.

  • Voltage alone does not equate power or energy. Watts = Volts & Amps.

    Does cooling the panel produce more Wattage? THAT is the question, that remains...

  • ha, interesting!

  • it's so useless, 2volts is nothing. if there is a capacitor inside the solar panel it will be the reason it is not rising in volt that fast. when you walk by it only drops 2 volts too maybe because of the capacitor.

  • What if we use a water pump that pumps about 6 gallons per minute up to a soaker hose . The pump I looked at shows... Power: 25 watts * 396 GPH Output

    I'm getting 5 panels 135 watt each about 27" x 60" x 1 3/4". Could that pump of mist or recirculating water be worth the 25 watts used? IF 9% is accurate for larger panels then 135*1.09=147.15 next 147.15-135 = 12.15 x 5 panels = 60.75 - the 25 watts used by the pump = 35.75 per hr about 175 more for 5 hrs. Great tip if it works like this.

  • @km0veritasaequitas you will get water marks all over them and damage them. unless you use distilled water that is pure h2o

  • This is the 3rd video I have seen from you today. I appreciate your dedication and obvious passion! Great job...

  • GPS is the same as buying diet coke, you're getting some science, but its filled with crap. Its technically right, but its garbage.

  • =OoO=

    *HEAT* has always been the BANE & demise of Electronica.......

  • Dan, I have a question. Can these solar panels be connected in series and a series of panel chains connected in parallel to: 1)increase voltage to something that would be practical in terms of tying into house power to supplement what I get from the commercial power grid; 2) charge a large bank of deep cycle batteries that I can use in times of power outage which we get a lot in our rural area here in northern Virginia?

  • @lrb1e39 These can be series or parallel.

    watch?v=N86eHRGRJwQ

    

  • @lrb1e39 Also keep in mind that if your wiring the panels in series up to a commercial voltage such as 110V, the current from the panels is DC, not AC like commercial power.

  • No surprise here. Semiconductors lose efficiency as they heat up.

  • Merry Christmas Dude.

  • yay! 3volts....

  • @shithustler420 And how long did it take to put it in a tank? Its very easy to do, saves money; worth the 3 volts. Please don't be cynical of someone with good ideas and an honest pupose.

  • @shithustler420 just wait for it to be developed further. 

  • I Really wonder?, what this conceptual idea will look like in 3 years?? Remember the Bat-mobile In Car radar,, onStarr anybody Reference: Darmstadt University of Technology in Germany won the 2007 Solar Decathlon in Washington, D.C. with this passive house designed specifically for the humid and hot subtropical climate Renewable energy Ideas: Biofuel Biomass Geothermal Hydroelectricity Solar energy Tidal power Wave power Wind power
  • Water and electricity...what could go wrong?

  • I think a more practical option would be to use some kind of a heat sink/dissipation device at the back of it. But if it's only a volt or two ... then does it really matter? Interesting idea about a hybrid heat/pv system... that could totally work... if designed for this purpose.

  • Heat it up to separate the layers.

  • With all the comments here about people never seeing a liquid-cooled PVP, I'm not even going to waste my breath putting mine next! What about a seporate PV unit hat powers a DIY liquid cooling unit. This way, as the unit heats up, it can pump more coolent through the lines and become more efficient at monitoring the temperature of my larger pannel grid. This would probably increase the life-span of your standard pannel as well! Good job man! Absolutly fantastic scientific observation!

  • I'm thinking small artificial ponds with mirrors on the side walls...

  • Tiz good to see folk turn take a step back and not be so relient on big companies

  • Can you test it with ice in the water too? Would be interesting to plot Temperature ver power output. Grate vid thanks for posting.

  • Ok, I have a GLASS FUSION KILN used for artwork: 240 VOLT AC 2W. 1 PHASE 34.7 AMP, 8320 WATTS. Is it possible to use solar to operate my kiln(s)? What would it take and how much$ with all the parts if I did it my self? I can weld a stand for the solor to. whree does the energy store? Or is this just to much amps? Thanks call direct for guidence on this. I am serious about doing this. 6129684745

  • Hi, I am a glass fusion artist. Is it possible to run my glass kilns off solar? Here are the stats for my largest kiln. What would be the cost to build my own set up if even possible to produce enough electricity for a fire. I weld to if I need to build a big stand for the solar panels. Stats: 240 volts ac 2W, 1 phase, 34.7 amp. 8320 watts. How many solar panels and what do I use to store the energy and convert it into my kiln? 6129684745 to help guide me.

  • great vid...its so sad that our country has become a big currupt corporation...hemp, solar, wind and bringing back family farms can get our economy back on track and end food shortages and wars, but the banksters who make trillions off oil will never let it happen untill brainwashed americans wake up and take back the power....everybody go watch K-Rino - Grand Deception.....and Fall of the Republic

  • That one was COOL DUDE ! I like scored it and favorited it because it was suggnificant. A promising find. On a massive scale a pump trickling water down from the tops of every cell could be a voltage jump that is enough to be more than noticed. Keeping it clean and adding a small amount of water magnification distortion. Didn't Obama say he wanted to do a massive scale solar panel farm somewhere in Arizona ? I say leave a note for the president on his desk. GOOD LUCK !

  • So do you think you get a 9% increase bc of the surface area of the glass collecting more sunlight than the panel would in regular sunlight? I guess you could say it was like a square magnifying glass. Just a thought. Thanks. Great vids. Keep up the good work.

  • Could you not just submerge the panels in mineral oil like they do some custom computers since mineral oil or vegetable oil doesn't conduct electricity enough to cause harm and would greatly reduce the overall temp? just a thought. Let me know what you think. Thanks.

  • I'm thinking solar pool covers, or perhaps solar panels at the bottom of swimming pools :P

  • a 2 volt power loss is a b ig deal for me! i gotta try that!

  • can i has your broken panel?

  • Would the roll out pannels work under water and double for a pool heater?

  • more voltage because water creates lense effect increasing light to cells, not because its cooler!

  • Excellent! I've seen some comments that temp of the water will rise to 135 as well... well it is the minor problem. If you place a panel in the water tank which is connected to a bigger tank underneath that system trough heat pipes, you'll get much slower heating of the water... and also kind a temperature collector for heating water. If it is known that sun shines for about 10-16h a day (depends on the location) it could be easily calculated how big tank should be for optimal results.

  • And one another thing :) Did someone try combining this technique with a lens trick? :) Even water itself could be used as a lens... Unfortunately, I am not able to get one of these panels to try it myself... :(

  • Excellent video, My panels are starting to drop off because of the heat. I am building 40 cell panels to help compensate for the heat. keep up the great videos.

  • Great videos on your page:-) Excellent work on the DIY.

  • Great xperiment, 9 percent is a lot! This is money in the bank if you use it as an array for power production.

  • well want do you thank about putting them in a pool ? with wiring just out of the water ? I will see if this OK TO DO, Thank Dan , ty see ya

  • where are the fishes..........?

  • really cool

    i like how you test and prove all of your methods

  • Just a random thought here: But what about having the solar panels in water, then taking that heated water and using it for thermal?

  • can you make solar tracker using timer relay?i thing you can use 2electronic timer relay!!you know like the conveyor..

  • great experiment !!!!! i am just getting into solar energy, this video has been the most informative in heat variation so far. thank you for uploading :)

  • I think you're being a bit too simplistic about this. The problem isn't really so much to put it under water. It's that the panels need to be made with cooling systems.

    There are great PC water cooling systems that could be converted and scaled up fairly well to fix this problem. The problem is economies of scale. One would need to calculate the difference in power produced to power used by the cooling system.

    The main problem being that the temp of the water will eventually rise to that 135.

  • wow $25 sounds like a bargain

  • finally found some water proof panels for my solar submarine. Thank You

  • Put some ice into the water ;)

  • Could you attach a TEC to this and use the energy from the heat generated as well? Obviously not the one in the water. :)

  • WHAT IS A tec?

  • Looks like you came up with a water pre-heating photoelectric hybrid!

  • Then the increase in the output is due to the extra size of the Lens which intensifies almost double the radiation. My question thus is, if the size of the fresnel lens is the same as that of the solar panel, then what? will it still intensify the radiation? What if the focal length is shortened not by a lot but by a distance apt for a smaller lens? Will the output of the PV Cell be the same? or better...

  • Ok, after viewing this video a few more times, I have one more querry. In the video you have shown a fresnel lens which increases the output of the PV cell by a few extra volts. I was discussing this with a few of my engineering colleagues, and they say that in this case the increase is due to the size of the lens. Say the size of the PV cell is of an A4 sheet, and the size of the Fresnel Lens is of an A3.

  • I tried searching for these solar panels on ebay, unfortunately couldn't find any. I am doing my Masters in design in Milan and for my final thesis am looking for a small A4 size Solar Panel (if it exists), to try and build a small prototype, and show the usage of solar energy in a passive house. Building a home which is its own power house, and generates its own energy for consumption. Based on the 'passive house' could you help.!

  • "6W SOLAR PANEL"

  • But the aquarium glass and water in front of the panel also cut the light perhaps by 5-10%. If the panel would be cooled only on the back (like making an aquarium with the solar panel replacing the front glass) it will be both cool and receive more light than submerged.

  • @pisoiorfan oh man thats a wonderful idea :)

    must try this:)

  • How about building a Fresnel lens water tank and pointing a parabolic mirror into it with the photovoltaic panel collecting the most refracted light.

  • What about the light refraction is greater in water.

  • what it help if you used aluminum foil or and any kinda metal around it??

  • what you need to do is to use reflectors to concentrate more light and and cool it. now that would be really cool.

  • ok i got an ideal....the power plant should build 1 ft deep ponds and put solar panel in it 1" under water...the ponds could be as big as they want but the panels should last longer it they us on for couple air pumps...

  • @freakshowboy9 Then you have to counter evaporations.

  • Wow, im learning alot thank man

  • i like wat ur doin man. . thanx for ur lessons. .

  • Hey, The optimum temperature for solar panels is 25 degree centigrade

  • well its the same as puting a magnifing glass in front of it ,, or water ,,or even a thin piece of clear ice ,,in front of it ,,,only thing it makes cooler as water.ice has a cool quatiies ,, as magnifing glass makes it heat up more un less u might put the glass a lil more darker or tinted a lil bit but not sure on that

  • make a sandwich, botton, insulation material like .5 inch polystyrene, then plastic, like 2mm thick, then the solar cell, gap underneath for water flow, then a glass front, with gap to allow water flow, now you have the solar cell cooled back and front, and its also a solar water heater....

  • Yeah this is really good - there are a fair number of organisations out there pursing the issue of cooling the cells - and using really really intense solar concentration levels.

    Last time time I looked they were pushing up to around 2000 suns, and many of them were suspending the cells in a "sort of" fish tank, and pumping acetone over the cells as a coolant.

    The physical limits have kind of been reached there.

  • just make a spay nozzle to spray the panel thats what i do, putting it in water you have reflection and refraction of light as it passes through the water.not very good demo.

  • lol sorry didnt see you had put it under water damn you have done alot of vids man keep them comming.from watching you and looking at the FRESNEL LENS + the sterling engin and a invention of my own it get big power output makes them 150k macines look like there from the dark ages.

  • :-) Thank you for the great comments.

  • Cool Findings? No - it's an established fact - the HOTTER the solar cells get, the less efficient they get too (except for amphorous ones - up to a point).

    The BEST way to radically increase the output of a solar cell (again up to a point) is to concentrate the light on it, and heat sink the solar cell to a cold resivour - like a "hot water tank" and heat the water in the tank from the heat sink, up to about 40 - 45*C

  • Bingo - small and cheap solar cell unit making stacks of power and free hot water without a solar water heater.

    Not sure of the exact details in all of this in terms of electrical insulation on the underside of raw silicon solar cell slices (the qualification for the following statement); but one would need a thin film of silver based conductive heat sink compound to transfer the heat out of the cells, and into an aluminum heat sink with a water channel through it.

  • OR one could insulate the back of the cell with a a very thin film (? can't think of what) and then use direct water cooling on the back of cell surface it's self.

    OR even both sides of the cell......

    Dans idea is quite a good idea.... it would be interesting to see just how far one could reliably push a 2V single 100ma cell (making that value up), through a solar concentrator and a form of liquid cooling.

  • This video is not for electric engineers.

    Most people do not know that resistance of metals depends on temperature.

    The interesting fact in this video - very simple way for cooling solar panel, and even in the not clear water it gives more energy than the same heated panel.

  • who said you're smart? your grandma? :))

    "The physical limits have kind of been reached there. "

    lol, go finish school dumbass :))

  • Cool findings... it would help if you did some more control testing... and realized that watching a dark display with a bright background on camera does not work well.

  • Ha ha. You said "Cool findings", get it?!  Ha ha ha. Okay, not that funny.

  • to early 1900's

    the electic eel ieda will not work and is very dangerous the reason it won't work is because large amounts of electrity at a short rate cannot be harnessed 2-5 seconds the is the same reason as to why power station don't have long electic poles with wires ontop to harness thunder which is about 45 kv that power will simple blow a fuse or been disposed of usually though earth wire hope this helped to clarfiy few things.

  • I don't think its' because it's cool. I think it's because the water offers more reflection and more angles of light, and that offers MORE light at HIGHER doses. It's like holding a mirror up to a solar panel. I don't know if this is right, but I've seen this experiment done before with mirrors and water reflects light.

  • If that were the case, the voltage would have risen instantly. All solar panels and electrical devices work better when cool because of less resistance in the circuits.

  • Dan,

    Thanks for all the great videos!! What type (brand) of solar panels are you using in this video??

  • Hi Dan & Denise, not really related but I just read about an electric eel in Brazil that can produce 650 volts to stun prey and can stun a human.

    Do you think it would be possible to keep on in a tank and harness its power? Or am I just being silly? It was just a small 'did you know' article and didn't provide much more info, like how often it can shock in sequense. Would be good free power if it worked?

  • col discovery!

  • did the water give any prisum effect and if so would this aid the solar process?

  • it might be silly question.but can a magnifiy glass help focus solar energy towards the panels gerate more energy

  • Good question:-)

    watch?v=-yh1q59a1h0

  • Try a mirror instead, that way it won't burn out immediatly.

  • i see great future for the submersible solarpanel for marine and sea use, but wonder if marine water would affect it.

  • so in theory this panel can possible be made it to a marie or sea use. I would like to see a video of this and I see a great

  • really cool

  • If it was the light tank, the voltage would have increased instantly vs slowly. Poly Cells, un like these cells have a metal backing so heat sinking would make sense. This was totally the cool water

  • In electronics, as circuit temperatures rise, circuit resistance also increases. Heat will decrease the output voltage. Most passive cooling systems will help to increase the voltage output. The only problem with the water solution is that once the water heats up, it will retain the heat longer. If you could circulate the water it will increase the cooling capacity greatly. I realy enjoy your vids. Great stuff and thanks for sharing.

  • is he... sure.. That the glass in teh tank wasn't refracting more light toward the Cells? that would increase the voltage.. Same as replecting light from a mirror onto an already lit panel.. Or his fernel lense when he pointed it towards the cells.

  • I think that when distilled water is used instead of normal tap water, the results will be a little better because it is more clear. Also distilled water doesn't conduct electricity ...as far as I know.....so there is less danger of shorting out your solar panel.

    I don't have a solar panel, but I would love to see reactions from people that know more, or are willing to put up a test with distilled water and normal tap water to see if there is a difference in efficiency.

    Greets, InsAneTunA

  • I think you could get an even higher voltage with the cooled panel because :

    - part of the solar panel is shaded by the black edge of the water tank (5% shaded = 5% losses)

    - the panel is not exactly facing the sun (because it didn't fit in the tank, so you put it a bit side way)

    - your water doesn't look very clear on the video, maybe distillated water would be better

    - you don't need to have that much water in front of the panel, 2cm will be enough.

    great video, keep up the good work

  • to other people:

    - you don't need a pump to circulate water, you just need a deeper tank with a radiator at the top, to use the convection effect: (hot water rises)

    - using it to make hot water is not a really good idea, because you have to make a compromise between water temperature (higher the better) and solar panel temperature ( lower the better). it's more efficient to have 2 different systems.

    such a "hybrid system" would be good for pool heating because you don't need high temperatures.

  • Interesting but you will get plenty of algae within a weeks so I would reconsider whether to use water in a transparent tank.

  • two thumbs UP!!! ;)

  • amazing 5 stars!

  • Coal and Oil companies are PURE EVIL. There are so many amazingly smart people with incredible ideas that can improve the world. But, the political will is still not NOT where it needs to be...YET.

  • yeah!!! you are 100% right!!! politics all in all are all evil...

  • Hey the temperature difference is not the strict control of the voltage, you also have to take into account for the magifying of the light through the water.

  • Obviously, if you encase your PV modules in a water jacket, you will void the manufacturer's warranty. Using supplimental light gathering, such as lensing or reflectors to concentrate more sunlight on the module, will also void the warranty.

  • can you give an amp reading per panel and the actual ebay link to purchase a few?

  • personally, i'm sold on the higher volt readings of the wet panel, and it would have to be proven otherwise, to me at least, that the one in the sunlight can produce more power. although the ammeter theory does make sense

  • good shiza yo

  • curious research

  • The implications of this are quite astounding when you consider the kinds of super coolants that NASA uses on simulation supercomputers. If they can afford to build gigantic panels in the first place, it would be a small matter to run coolant tubing between rows of chips. If you put together the proper combination of conductive materials and coolants, some good engineering could reap almost 100% efficiency per panel. Makes the "bailouts" seem an even more pointless use of government funding, eh?

  • Sure...and to continue the idea: The "coolant" could simply be water that would also end up getting heated-up as a result of moving through the PV cells. POOF! Hot water for your shower!

  • Great video!!

  • At Solar Bike Rayce, we spray our panels down with water to make the batteries charge faster. Keeping the panels cool gives us higher current.

  • I don't want to put solar panels on my roof, I want to make a solar panel roof. If you were building a house, don't you think that would be better? You would save the cost of the typical paper/tar/nailed roofing costs.. Maybe a tongue and groove watertight panel 16" by 14'.

  • Hell ya. Randy know whats up. Thats one darn GREAT idea man.

  • The problem with Building Integrated PV Roofing Tiles is that they are made with thin film technology which is half as effecient as, say, monocrystiline PV. If you're going to be grid tied, your system has to be approved by the Utility Company, the Department of Building and Safety and the local Fire Department. If you're going off the grid, you'll need battery back up for night time, or a back up generator ad you'll want really efficient PV modules.

  • lol dan,

  • Thanks for destroying your panel for this lol

  • The one I ripped apart still worked.

  • i suppose one could just put the panel in a large clear plastic bag before submerging .

  • ρ = ρ0(1 + α(T − T0))

    The resistivity of a conductor increases with temp. Copper, which would normally be used in a cell like this for wiring will have a fairly linear reaction to heat.

  • In the tank faster + 22v reading

    No Tank slower 20v reading

    Amps have to be more, that motor is a load, it is geared, bet you could not stop it with your finger.

    I believe that particular motor is 15:1

  • Also, I should of not said "no load" but minimal load. High volts turn motors faster, and surge of amps is what gets a motor turning. This is why you need to use what's called a Linear Current Booster with PV to get motors (like in solar pumps) turning.

    Also, please check out the I-V curves for PV. What you'll learn is that in a near no load condition, voltage is maxed. But the point where the PV produces most power is at the knee of the curve - neither Amps or volts are at the highest.

  • In the video above the author makes a critical mistake - he assumes that since the voltage is higher in the submerged panel that it's producing more power. However, power is voltage times current and he hasn't measured current. A higher voltage will turn a DC motor (notice there's there's no load on the motor) faster but that doesn't mean the motor has more "umf" to actually move something. He needs to add an ammeter into his test to see what the real power production is.

  • You are incorrect and the host is correct. The motor is a geared motor and requires more power to accomplish simply spinning. There may be a bit of a difference in amps but the fact that the voltage reading is higher from the panel while spinning the Geared motor faster proves MORE AMPS and his point. 9%-8% it is still more and a fact. I saw a documentary on Discovery solar scientist stated "the North Pole is the MOST ideal because of clear sun, solar reflection and COLD - 25% more efficient".

  • Amps is the difference. Power = Volts x Amps. So the author can't claim more power is being created without showing us the amps. A typical silicon PV panel gains 0.45% efficiency for each degree C decrease. So minimal. And his panel looks to be thin film which has less gain/C. Single sheet of glass reduces solar radiation by 10%. Centimeters of water? Prolly lot more.

    For the sake and fun of science, I challenge the author to do the same experiment accurately measuring watts (IxV).

  • You are correct BTW in that colder temps do make a panel more efficient - and in arctic temps gains of prolly up to 20% can be had. Reflection off snow/water can probably boost by another 10-20% if shinning right. We've seen solar air heaters (not PV) increase in heat output by 50% thanks to reflectance off of snow.

    The catch to all this experiment is decrease in efficiency b/c sun ray's are traveling thru glass and then H2O.

    For the record, I think it's great Dan's doing these experiments.

  • Wow :) so how about a new design perhaps for a solar panel ? the solar panel could have an outer layer piece of glass(like double glasing) which would allow a tiny trickle of cool water to channel and flow over the panel surface to keep it cool. the water could be recycled from a large reservoir tank and filtered so to stop green alge or wat not from clouding the panel surface? i wonder if the energy needed to pump the water over the surface would still make the panel more efficient? :)

  • just an idea for roof top solar panels where a water cooling system can be installed ^ :) i wonder if a PC/computer water cooling pump,radiator and fan would be efficent enough to flow water over a panels surface? either way great video , and very inspiring. :)

  • Well, I guess power or Amps are the right units to compare, not volts...

  • I always enjoy your videos. I wish I had the talent to actually build the little projects you do. I have the ideas but mine never come out the way I want them to. Awesome vid!

  • Angle of the sun has nothing to do with this test. If that were the case, the voltage would have jumped instantly when placed in the water. Solar panels deliver more energy cold than hot. That is a known fact.

  • while i agree with his science, i think that it might show a better voltage based of angle to the sun. solar panels loose alot of power when the angel gets off at all

  • The amount of energy that the panels collect during the summer is definitely more than in winter, it has nothing to do with the hot/cold, its to do with our distance from the sun :/. Cold != less energy. Cold makes greater conductivity.

  • 4 acidhax yu r Grrwrong did you know that in the northern hemisphere winter, the earth is FERther away from the sun than in the summer!?!?/,./., get off the acid, read a book.

  • hey i cant find thos panels on ebay. what are those listed as.

  • EBAY SEARCH THIS "New 12V 6 Watt 400mA Solar Panel Power Charger"

  • thanks! i realy enjoy your show.

  • :-) THANK YOU

  • An interesting idea - could you not power a heat exchanger with solar panels, that draws heat from the panels and increase their efficiency and at the same time collect head for warming the house during the night?

    That way wouldn't you end up getting both more electricity, but also as a "by-product" heat that you could also make use of for other things, or would it just be crazy?

  • Now this was scientic. Great info.

  • that is true. any conductant's conductivity will decrease when heated. just like what happens with an old-fashion light bulb. solar panels have ALOT of silicon fibers and wires going through them so temperature really makes a difference when you have so many wires heated or cooled. and I have seen solar panels that will only heat water. they have a glass layer on top with water in between set at an angle with a water tank at the top of it. that way, the coldest water will always be at the panel.

  • Good video. And yes water actually absorbs light. So putting them deep underwater like in a pool will actually take away available power. At about 15 feet the red portion of the spectrum is completely absorbed. But from your experiment heat effect the panels much quicker. Not really sure how to keep the panels cool with water and not have to deal with adverse side effects like algae. Or having to run a pump all the time. Although it might be good to locate them on ground instead a hot roof.

  • thanks for correcting me. i like your vids by the way. peace :)

  • :-)

    Thank You

  • i got the same results as you but my reason was to cool down the panal by submerged it in the water, I wanted to ask you where can i buy a powerful stirling engine to buy of the shelf which is efficint ... usually i find very wqeak ones i want one which would generate about 5 - 1000 watts not less or more... i appreciate if you know it i need for experiments, thanx

  • the water acts as a lens right? so why not also use a magnifying glass or a fresnel lens?

  • Hi Mike,

    The water only absorbs the heat. Notice how the panel took a few seconds to raise the voltage 4:50 Also, I did use a Fresnel Lens towards the end 6:05

  • cdltpx has a point, and also doesnt evaporation remove a lot of heat ? if the timing and volume of water was calculated you may be able to have the surface of the cell being exposed to evaporation at all times , just a though.

    again great work Dan

  • Dan you have done it again !!! how good was that !!! do you think the gain would run a pump for water circulation ?

  • This panel can do a small pump. There is a nice power boost. You may run a slightly larger pump slower. There are fountain pumps that run on panels about half of this one.

  • Plate glass cut and bond to submerge each panel in running water1/4" top and bottom place each setup over a dish that can concentrate focal point to the bottom of the water tray panel face down the cooling needs to remove heat of all that power you need a decent flow we are talking flash boil temps. I bet you double output of each panel with a dish and some throw away glass and some silicone. Find a way to measure water flow needed to cool.

  • The sides can be anything as long as they contain the water &allow even water introduction like a radiator does these trays can be built quickly for cheap get each problem worked out then integrate the entire system with a sun tracker. Each panel will have such out put you will greatly reduce the cost of panels by making them so efficient at peak times when energy cost the most.

  • I wonder if the cooling water really makes a difference or is it that its behind the glass and makes it produce more power because the glass makes it like a magnify glass

  • interesting idea, excess heat diverted through a primary water heating coil and transfering excess heat to hot water system.

    One problem though may be biomass generation and build up of carbonates in hard water areas?

    Great video though, thanks

  • now cover the back with Tec modules and make electricity from the heat "Thermoelectric cooling"

  • Great video. Simple, yet very effective research with good results. Keep up the good work. :)

  • looked to be about a 10% increase. Not bad, thanks for the video :)

  • Dan,

    Great job I always wondered if the the refracting light in a swimming pool would increase the output of a solar panel. Thanks for your info, Mark Tahiliani

  • How about spray mist on it?
