with the lense it almost pushed, 50% to 100% more power… Interesting. What are the cooling methods?
it only works when …
it only works when there is sun… light from the sun..cold and rain and snow doesn’t affect it a lot.. but there should be sunlight.. and lots of it to work…
fuck pv lets think …
pv lets think of something else
dan here ^ placed …
peace.
dan here ^ placed a panel in a fish tank to cool it on another video, so i wondered maybe if you could place all the hot parts of the solar panel between two layers of glass ( like double glasing) and channel water through those layers?) I only say this because water draws heat away fast and can be taken far away ( piped), hek im no expert like you guys , but i just had this thought the other day an hoped to share
Would be nice but …
Would be nice but the electronics are on the underside and heat rises. You need to heatsync the bottom. The water however is good at keeping the pannel clean. I work with solar pannels and there are a lot of people working on effeciancy vs heat problems.

a trickle of cool water over the surface.?
what about in the …
what about in the snow..here in montreal
thw weather is really cold it will be good?
it seems to be a …
it seems to be a mixed solution: solar and lens heater .. yes it could be done… in way that heat is captured under the solar cell… yep … let’s do it !
It would be nice if …
It would be nice if the lens did not produce heat. Since heat increases resistance it isnt quite that great of an idea. However reflection inside the pannel with diffrent materials is being developed currently to increase effencincy. For now not much we can do to make em better untill that next big break through comes out. If you were to use that lens you would need a massive underground heat sync. Its already hard enough to keep big pannels cool.
I would attach an …
I would attach an aluminum block to the rear of the panel and run copper tubing between them. Using the city water as an input, you could direct the output into a hot-water tank, or a dedicated heating panel if the solar cooling was inadequate to heat the water to your liking.
I’ve seen friends machine their own water blocks for CPUs and such. They cross-drill the block and plug the holes where they don’t want water flow. Works like a champ for CPUs.
I love videos like this! Props + five stars

That would be cool but Spectrolab’s minimum order amount is $7500. Not exactly in the budget for the backyard experimenter.
To Dan: Great Stuff! Keep it comin’.
I’ve seen (on the ‘ …
I’ve seen (on the ‘net) power companies in California that have used Fresnel lens’s to increase power output with PV panels. They ran a cooling system on the backside of the panels, so they not only got more amps from the panels but also thermal energy from the cooling system itself.
well, the stirling …
well, the stirling engine might be nice but the efficiency of the thermal engine/cycle is quite low
omg, I just saw the …
omg, I just saw the next video lol. Sterling engine.. sure enough I was going in the right path.
Has anyone heard of …
Has anyone heard of a Sterling engine? It runs off the heat of objects around it. The most practicle thing i’ve seen it used for is to circulateing moistured hot air in attics. Whos to say that you couldn’t have a flat alluminum tube that could flow below the panels (connected metal to metal for better heat sync and have a small but effeciant air flow? My motorcycle has no water cooling. it’s metal design is to release the heat through rivits that extend out in rows. God this is a puzzle!

I love your videos – so informative! But the more I look at these technologies, the better the grid looks!

Most people use them to empasize a point.

For multiple units You’d have to space the cells out enormously if you had an array of fresnels touching. Not too disastrous but space consuming. What’s the price of a fresnel compared to a Phv chip?
yes, but for space, …
yes, but for space, they are using specially made solar cells. If you really want to get an idea of some super high concentration cells, and make that known to viewers, I’d spend a little money and buy some CDO-100 Concentrator Photovoltaic Cells from Spectrolab. Their efficiency is around 50 W/cm2. Their 1cm2 solar cell produces around 18watts of power if properly configured under a solar concentrator. I would attach this to a ceramic heat sink and do tests with your lens.
Heating of Solar …
Heating of Solar panel reduces its output,
Use this but remember to reduce panel temperature to get 10 to 18% more output, Use of MPPT charger also improves efficiency.

It is a tough fight and video helps solidify some ideas. Youtube like sites are speeding idea sharing 1000x over. Maybe we can all get our flying car soon:-) Hope to see some videos from you soon and please feel free to subscribe and or share ideas. I would like to hear more.

I was suggesting all this on my discussion board a couple years ago and the disinformation agents came out like th ecacaroaches they are, slinging all kinds of reasons why no idea on earth would work other than their puppet master’s decrees. Vile disgusting creatures they are. So glad a million more people have joined the Green Fight since then. Keep up the good work.

Not if you keep them cool and dont over do it. This is the new method everyone is looking at. especially for space.
This is 12 volt …
This is 12 volt loaded at 500 mAMP or .5 AMPS. So = 6 watts.
The load with the light on NO lens = 11 volts so it is 6 watts. The bulb is actually a bit much for this panel.
With the lens the bulb is full 6 watts with 2 volts extra. So it is about a 25% increase across the board.
