The NewPowa 75w high efficiency panels I am interested in might or might not come with bypass diodes, but after I read this excellent post
I think in my setup, 75wx3 in parallel, the bypass diodes are not useful anyway.
Most popular panels, like 100w Renogy has 2 bypass diodes in junction box, if a panel is partially and baded shaded, it would lose half of it's output voltage even with a bypass diode. which is ~18v/2 = 9v, this isn't high enough for MPPT SCC to charge my battery anyway.
Is this the correct understanding of bypass diode?
Thanks!
Crazy diodes and not useful videos on YouTube, Make a diode video Will
So as some of you may know I,m having some power issues with my system. Have two 150 watt panels in parallel but noticed low power even in direct sunlight. I did some research and found it could be a faulty blocking diode. but here are the issues I've had. Tested both panels in normal sunlight...
