I bought about a hundred cells. They are 6x6 inches. although I need a better multimeter in order to test them (I will have it soon) they are supposed to generate about 4.8 watts a piece at about .6 volts and 8 amps. I've been practicing soldering them together and I'm ready to get serious. I'm planning to building a panel of sixty cells, 6x10. I'm pretty sure I will wire them in series which should give me about 288 watts at 36 volts and 8 amps give or take a little here and there for resistance. My trouble is, with all my research I still can't figure out what I will need for diodes. I know that most good charge controllers have them to prevent my batteries from discharging back into the panel. But I also think I ought to have some inside the panel. Ive researched blocking diodes, bypassing diodes, and isolation diodes, among others. However, I can't seem to find any information describing what strength of diode I should use. I want to protect the cells from backflow and bypass cells that may be shadowed briefly. Does this make sense? Am I making a mountain out of a molehill? Also, how many should I use.
No announcement yet.
Diodes. How big and how many do I need?
