Peltier Generating More Watts Than A Solar Panel

[franco malgarini]

I assume at minus that one cell produces 10 W
400 cell (1 square meter) produce 4 KW
and cost 1.000$

There is a temperature difference factor that needs to be included


Not just rated output


But rated output per difference in temperature


we can realistically achieve ~230 degrees in full sunlight
with a simple solar oven


Upwards to 10K with an Eric Jacqmain (Archimedes) device
But this process is constricted by surface area


Ideally, we want to find the best performance per area, per temp diff. per cost

Want to make some real power

Hi Sm0ky

I do not understand why you prefer this TEG module? As i see it, your TEG modules have a bigger surface area and lower rated output in volt - same time i see no claim about Amphere so i have no clue how many watt it can output? Did you figure that out?

You like to make it important which temp diffrence is made, why? What is important to me is that i have a steady heat coming that i can convert to electricity.

It is not a question of making as much power as you can, it is a matter of producing energy so cheap as you can.

If I build a plastic box 1m2 and 10cm wide then i produce alot of heat like 60c and during day i just get new energy all day long - this box i can build at 450dollar.

You talk about building a reactor where you squeeze in my 1m2 to maybe 50cm2 that have heat at 300c - but you will not get more energy from the sun by using a reactor, sun adds like 2kwh of power per m2 - you cant get more out of it!!! but you reactor might cost 1000dollar while my plastic box might cost 20dollar.

And you TEG module cost 20-40dollar a piece, while my peltier cost 6,90dollar per module.

If my peltier module will work then i feel confident that this is the way to go...but i agree it would be a big help if someone could test what is best.

Temperature difference to Watts is how these devices are rated


Greater temperature difference = more power output


Hi-Z is the industry leader in TEG units.
Not the Chinese


You get what you pay for
They are more expensive, but can actually produce a useable output


The TEC's from China will barely run a small motor when you Light them on Fire
Pull one off a computer and stick it on the engine block of your car
You can meter it
Then watch it as the cold side gets hot and it almost stops producing power
Now you have to run a fan or liquid cooling system to make it work
you see the power produced - cooling power consumed
Leaves you with nothing compared to a TEG with the same cooling system.


There ARE some similar looking TEGs that work better than the TECs
But you have to know what you are looking at
