A solar photovoltaic system with hot air recovery: http://www.pvtsolar.com/more_energy.html

But still ?????

Hello,

A not at all clever "trick" which recovers heat from the back of the panels for air / air heating.
Z'en take the opportunity to double the price .......

Obelix

I have not understood everything: he wants to heat the house + pool and spa with a few m² of hot air? And what does the groundhog do?

Solar thermal PV combined systems are not new ... but it is quite limited I find or so I did not understand the principle?

Can not be clever at all for some.
For me, who loves innovation, the thermal coupling - photovoltaic is interesting and I had never seen this type of product, hence the post Elephant.

For the price of the material, I do not know it, and a single installation operation is necessarily economic Obelix.

Ben there is system combined PV water for a moment ... in my opinion it is interesting but may not be eligible for subsidies ...

So it's still marginal? Nothing prevents to make a system of "cooling" for its PV panels (in order to increase their output at high T °)

I have never seen this type of product, is it possible to get some links Christophe?

Thank you in advance.

Some no

But here is one already: http://solarwall.com/en/home.php

There is air so like at PVT Solar so not great in my opinion ... but as 80% of the Ricans get warm in the hot air ...

I will try to find another one with water.

Here is a nice report of solar test bench of a hybrid PV and water sensor: https://www.econologie.info/share/partag ... U6hA3w.pdf

And there, the corresponding technical sales doc

Performance: 140 Wc / m² of electricity and 650 Wc / m² of heat.

Surprising that we did not think about it sooner (it's still quite new) but in any case it's much better than the forced air system of PVT Solar (I still have not understood how we could hope to heat a swimming pool with hot air ...)

Yeahhh as they say in Kentucky.

Thank you very much Christophe.
