Underwater SOLAR PANELS 9% Stronger PV Photovoltaic Sun Power

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:-)

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.

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.

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.

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 a fantastic video.

Commercial Solar Panels are Expensive!

Your Only Option is to Build Your own Solar Panels

one word: COOL! =)

@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.

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!

[bluediamond2077]

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

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

[1reneschlegel]

very cool and significant experiment. congrats.

[Rafreaky07]

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.
