Underwater SOLAR PANELS 9% Stronger PV Photovoltaic Sun Power
By Solar Expert
This test illustrates the efficiency drop from heat buildup in PV panels and how water can be heated while the panel produces a more efficient energy yield. Dunk at you own risk:-)
I must admit, I had not thought about solar panels getting less efficient as the sun heats them up … very clever.
@freakshowboy9 Then you have to counter evaporations.
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.
This is the 3rd video I have seen from you today. I appreciate your dedication and obvious passion! Great job…
@shithustler420 just wait for it to be developed further.
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…….
@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.
@lrb1e39 These can be series or parallel.

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?

No surprise here. Semiconductors lose efficiency as they heat up.
Merry Christmas Dude.
yay! 3volts….
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

Water and electricity…what could go wrong?
check out my channel for some nice solar powered revolving models. (all for sale too!)
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!
@pisoiorfan oh man thats a wonderful idea
must try this:)
