Using a Zener to protect devices from solar overvoltage
I am making some pretty crude devices that are directly powered from solar panels. The instability is not an issue, but I want to avoid over-voltage. I am using two 100W panels in series and want to If the panel can deliver, say, 3A @ 30V, the transistor will dissipate about 88W and the zener will dissplate about 2W. Share. Cite. Follow
