Powser Supply Size - P_10 p Panels

Recommended Posts

Source hardware for P10 panel built and up next, power supply.  First time I'm using 5v, so just want to confirm I on the right tract. 

 

Took some digging but found P10 16x32 output numbers on another forum.   For full white, it was measured at 1.38amp. 

 

Did a amp to watt conversion which was about 6watts at 5v.

 So for 6 P10 panels and the Raspberry Pi/PiHat, seems that a 100w-18amp power supply would be plenty? Can't ever imaging running all panels at 100 percent white.

I would have to measure mine again, but that sounds maybe a little low, but in the neighborhood.  BTW, you better check your math.  1.38 amps at 5 volts is just under 7 watts.  I do know that two P10 panels in full white will run on a five amp fuse (two P5 panels will not for very long).

When I had both my 6 P5 panel array and my 12 P10 panel array hanging in my family room for test, they were powered by one 350 watt supply with gobs of spare capacity.

I agree that number seems  really low. (~1/2)

BUT the bigger question. WHY are you trying for the smallest power level.  The price difference in the 100+W range  is small.  $25 for ~300W or $30 for weather resistant (fan dow, vertical mount)
