Underwater SOLAR PANELS 9% Stronger PV Photovoltaic Sun Power

January 8th, 2010 | by admin |

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:-)

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

    Then the increase …
    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 …
    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.!

    But the aquarium …
    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.

    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 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…

    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 …
    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.

    Video that – and it’s for idiots like you.

    Mention a few issues like gravity, wearing steel cap boots and pulling your feet away in time – and it’s for smart people like me.

    Shit for brains.

    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.

    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.
