Old house panels are very cheap or ewaste in many areas but they should still be functional for many years.
What are your thoughts for the best way to use them?
I'll nominate the ReneSola 125 Series 200w panel as the basis of discussion. STC:
Pmax 200W
Imp 5.41A
Vmp 37.1V
Isc 5.7A
Voc 45.3V...

Using a Drok DKP6012 converting 10V-75V down to 0-60V at 12A/720W works well as a nice cheap fully functional system for a house solar panel to 48V battery.
I'd like suggestions for a cheap programable buck converter to swap out the Drok...
