Schottky diode is preferable as a bypass diode than the normal pn silicon diode because it has less voltage drop of about 0 4v where as normal si diode has a voltage drop of 0 7v.
The schottky diode has lower forward voltage drop of 0 4v as compared to normal silicon pn junction diode which is 0 7v.
The schottky diode named after the german physicist walter h.

3 reverse leakage current inoperation reliability of bypass diodes in solar panel applications.
Just about any general purpose switching or other low power diodes can be used for these circuits however schottky diodes have lower voltage drops and work very well.
Schottky rectifiers feature low forward voltage drop offering higher efficiency and current density than traditional p n junction diodes.
Blocking diodes will be of benefit in any system using solar panels to charge a battery.
In normal solar panel operation the bypass diode.
