The Corner of the solar electronics:

The first solar thermal systems were governed by a simple physical principle of energy transfer, the thermosiphon.

Despite its benefits in terms of simplicity and especially the fact it does not require electrical power, (i) it is not suited to face the gain of efficiency of all the element of a solar system, and (ii) and dictate significant arrangement constraints (leveling, slopes of the connecting pipes ,...).

The addition of a circulatior overcomes these drawbacks and add a few points of efficiency. But to be truly effective, a bit of intelligence must be added to the system or at least a bit of automation ... That's where the electronics comes into play.

In recent years, I have been trying to put the Solar technique accessible to everyone by posting on the APPER forum electronic circuits. This circuit were inspired to me by the self-builders members, installers or DIY geniuses, and they are not necessarily knowledgeable to this a little bit obscure technique so-called electronics.

But this page is yours ... You who have hacked a little monting in your garage or a super card laser sight, and GPS card, please, share your experiences with everyone!
