Wow I didn’t know that! I figured all panels would all work and not loose voltage . So they all have to be the same watt to have no voltage drop. So am I better off selling the older panels and get another 2 100 watt renogy panels? I’m trying to decide how big of a solar system I need for lights...
I don’t understand . If I’m hooking these panels in parralel I will only have to worry about amps right because voltage stays the same ? And in series I have to worry about the voltage but amps stay the same . Just curious
Ok here is the specs off of the 75 watt panels
Maximum Power: 75Watts
Maximum System Voltage: 600V DC (UL)
Optimum Operating Voltage (Vmp): 17.0V
Optimum Operating Current (Imp): 4.4A
Open-Circuit Voltage (Voc): 21.7V
Short-Circuit Current (Isc): 4.8A
Here are the specs on the 100 watt renogy panels
Maximum Power: 100W
Maximum System Voltage: 600V DC (UL)
Optimum Operating Voltage (Vmp): 18.6V
Optimum Operating Current (Imp): 5.38A
Open-Circuit Voltage (Voc): 22.3V
Short-Circuit Current (Isc): 5.86A
Hey guys I’m new to this forum and im
Hoping to learn more about solar. I have (2) 100 watt renogy panels and I have 2 older panels that I got off of a friend they are (2) 75 watt panels so a total of 350 watts total in solar array. I current just have 6 heavy duty commercial batteries that are...
