I'm building a small solar project and am trying to use a S8550 transistor to work as an on/off switch depending on how much light is hitting the solar panel.
I've attached my schematic to detail what I have done. But I am finding the S8550 transistor is cutting down the current going through so my light is very dim.
I'm very new to this type of work so any advice as to where I am needing up would be super appreciated.
