    Pro: Dimensioni, facilita di cablaggio. Contro: efficienza, prezzo potrebbe essere migliore (pagato 6 euro). Lo uso con un pannello fotovoltaico (di targa ha 45W a 18,6v) per alimentare un circuito a 20V; funziona bene, iniziando a funzionare a 3,4V dove fornisce solo 100-200 mA per arrivare a in...

This solar panel can not be used because of low internal resistance to completely overload the solar cell, the solar cell voltage drops to 1-2 volts on which this is no... Read more
