Hello,
I just went thru this part number specs sheet. I would like to ask if I understand this correctly.
Is this module able to produce near 300 watts of energy at 27 degrees operating temperature?
Many thanks
Greetings,
The device functions as a heat pump; it doesn’t produce energy so much as move it from one place to another.
This post discusses the specifications for this type of device in some detail.
When it comes to thermoelectric modules of this sort, if one’s asking the question the answer is almost always “no.” It’s a tricky subject to pick up on if one hasn’t taken a thermodynamics course or two.
Beyond that, the devices are so horribly, awfully, wretchedly inefficient that a people who don’t take time to run the numbers are almost always disappointed with the results of a “try it and see” design approach.
Hi Rick,
Thank you for your quick reply.
I have seen many videos with thermoelectric elements being able to produce electricity, so i was wondering if enough elements could be used to charge 10kw of batteries, like thermoelectric power plant…
Many thanks

Practically speaking, no. This post goes into detail as to the reasons why.
While a person can use the things to generate electricity, they’re even more hideously inefficient at doing that they they are at moving heat. Roughly speaking, it’d take about 100 watts worth of heat to end up with one of electricity. That may be good enough for plutonium-powered space probes, but there are very few applications on the surface of the earth where their use makes sense compared to the alternatives.
So, is this thermoelectric module able to produce 300 watts at 27 degrees operational temperature? As per the specs?
Many thanks
To verify, Were you able to read through both of the posts that Rick linked earlier?
