Solar Installation – Flying High and Far Away
The title reflects the unique install. The roof layout for the panels shows the roof vent and skylight. In addition there are the evil shadow producing A/Cs and ladder. Three 250W Cynergy polycrys...

Series panels with bypass diodes can provide more power with some shadow conditions than parallel panels with the same shadow. My panels are similar to many in that there are 3 bypass diodes and each one can bypass 20 of the 60 cells so you get the same amps and 2/3 the voltage when one bypass diode is operating. For parallel that panel would have no output. There is a thread with testing on series vs parallel that is several years old and I'll see if I can find the link.
Having said that there are other considerations and many opinions on serial vs parallel.
A disadvantage of the MPPT 60 is that the efficiency decreases as the difference between the battery voltage and the array voltage increases.
