Watts needed
I have read where folks suggest any where from 1 to 2 watts of solar per ah of battery. My question, is this based on battery rating (ie 215 AH) or is it based on useable amp hours(105)? All reply...

All right, I need some more help from the experts. I am looking at purchasing 2 residential panels with the following spec.;
Watts (STC) 285 W
Max Power Voltage (VMPP) 32.2 V
Max Power Current (IMPP) 8.84 A
Open Circuit Voltage (VOC) 39.2 V
Short Circuit Current (ISC) 9.61 A
Max System Voltage 1000 VDC
Am I correct in assuming that a mppt charge controller that will accepts 100 volts and 20 amps would work with these panels.
I am currently trying to get a better understanding of charge controllers so your help is greatly appreciated.
