My ESC buffer and rotating panels - autoconstruit

[Hot water]

Hello everyone, very nice project and thank you for sharing

[swallowtail]

bravo for this installation self-built , the only economical solution (inexpensive).

I seem to recognize in your order electronics a kit
"T ° differential switch" conrad at 20 € ???

I also use this kit (very satisfactory for its price) for the management of my ECS Laing 24V circulator for my Thermal panels and the recuperator integrated in the insert.
a single fault: burnt out transistor, replaced by a 2N2222A, + tolerant of overvoltages ... and added a green flashing LED when the relay is actuated (circulator ON)

I am also considering the manufacture of a tracker for 2PV 175Wp, on an equatorial telescope mount design (rotation axis combined with earth rotation axis)
I will get an intermittent drive (- greedy in W), and return by return spring and automatic mechanical disengagement, or drive by worm and cardan nut and return by reversal of rotation screw sf.
