Question:
I have 1 solar panel with the GP -PWM- 10 controller. Does that mean that I can only upgrade this system with an additional 90 watt solar panel?

Hey Todd. It depends on what size solar panel you have but that sounds correct. A 10 Amp Go Power PWM Solar Charge Controller like item # 34280503 is going to limit you to a couple of 80 or 90 watt solar panels or one 200 Watt Solar Panel like item # 34282182.
You can always upgrade or add a higher amp controller like the 30 Amp Go Power PWM Solar Charge Controller with Bluetooth item # GP76QR.
How many panels are you wanting to add?
