cpv with regular pv.

use a infra red reflective coating on the glass.

Liquid Submerged Solar Panels + Fresnel Lens. Liquid will dissipate the
heat and amplify the power of the Fresnel lens even more.

how about instead of focusing light directly through the fresnel lens onto
the solar panel why not bounce the sunlight through the fresnel lens onto a
mirror aimed at a solar panel? that way you can easily control the degree
of heat energy directed at the solar panel with filters along the lights
path to the solar panel.

How much energy able to generate by fresnel lens and heat produced?

When focus sunlight on a PV do not have to watch the voltage but the
current is much higher.

Why not let it heat a glycol solution to heat your inside water? The water
is heated and the panel is cooled at the same time!!

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…

@karma7463AndSomeMore : it would help if you’d give a practical example

Why can’t you use a passive cooling system, such as an aluminum heat sink?

I read about a missionary who took some solar panels with him to South
America. He made a mistake of taking the wrong kind with him. He found that
the panels were not putting out what he expected, but when he poured water
over them to cool them the output jump up to specs. Maybe if a solar panel
was made with a water heat sink on it’s back would be good.

Hey Dan. Nice idea with using the lens! There are some applications on the
web for a ‘stretched’ Fresnel lens solar concentrator for satellites. The
lense material is not suppose to be as fragile, but I’ve found no evidence
of it actually being used. Are you familiar with any of those experiments
or the results?

Damn it, I thought I had something! Oh well. It’s nice to see that it works
though. As far as overheating, that may not be an issue in a place with
cold weather 365 days a year. So one solution could be to move to Alaska,
for example! Just make sure to “utlra-weatherize” your home. That would be
an ideal setting for a business that needs to be cold inside too though,
like a computer data center. Just leave doors wide open! I wonder how much
land costs in remote areas of Alaska…

Cooling is ez for electronics….nothing a heat sink cant handle
considering its only heat from the sun and not heat from a processor which
can burn you badly…. as for the distance…well thats just an easy
mounting solution.

If you could use say the shape of a 50 sided die and cut in half as the
lense, that would create a lot of solar exposure to one spot. As for
cooling the solar panel, you could drill down deep with some pvc piping and
some sort of fan to accelerate the ground temperatures back up. On a hot
summer day everyone knows that the basement of a house will probably not
need air conditioning especially if it is more than 6 feet down. It
probably would not require that much extra energy.

Instead of cooling the cell down, why not use a molten cell with
electromagnetic controls in a municipal solar environment?

good demonstration =D r u working with any company developing CPV? need
some info with non-imaging optics but fresnel lens sure rocks!

Why not put the solar panel under flowing water (are they waterproof?). If
you get some decent flow you could probably focus many times more light
onto it.

this is a completely different use for the lens, but i saw some youtube
videos not too long ago about people making soda can heaters by removing
the bottoms of cans and caulking them together to make tubes, where the lid
of the cans compartment it so the sun has time to heat the air inside. just
painted black the system turned 40 degree air into 200 degree air. i hope
you see where I’m going with the focused lens… i also saw some of water
heaters working similarly. hope this sparks good ideas!

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

cool. i wanted to do this kind of test myself. for cooling i would use a
natural circulation copper piping that would also heat up some hot water
for your house at summer. and at winter ofcourse you have to drain system
because ice could damage your system. I think its worth to try since you
shown >30 % more output
