Can I Combine These Trackers?
I have two separate manual trackers with two different brands of solar panels. Tracker #1 has eight  Arco 16-2000s (remember those?)- these are rated at 33 watts, open ckt of 21.6v, and rated at 16v. Tracker #2 has four (4) Siemens SR-90 rated at 90 watts, open ckt of 20v, and rated at 17v. They are 30 feet apart, are both wired in parallel for 12v with USE solar cable AWG10. Now, they will ultimately enter into a Xantrex C-60 charge controller, the battery bank, and finally a Exeltech XP1100. There are no fuses between any of the panels, but there are the appropriate breakers between the panels and the charge controller, breakers between the charge controller and the battery bank, and breakers between the battery and the inverter. I've read that you can combine different solar panels IF THEIR VOLTAGES ARE SIMILAR. So, what's the real story?
