200 Watt Portable Solar Panel for Geo Pro RV

Question:

My Geo Pro 15TB has a 100 Watt panel on the roof and a 1000 Watt inverter. How will using your 200 Watt panel help me and do I need a separate battery for that?

You can additionally connect Go Power # 34282610 portable solar power system to your trailer battery. Your battery will see the total of amperage coming from both panels, with their respective built in charge controllers, which will recharge your batteries faster. A very loose rule of thumb is for 100 watts of solar power you will want 100 amp hours of battery capacity. So if you have 300 watts of solar panels, that will be rightly sized with a 300 amp hour battery. If you are off by a little that is not a big deal. Keep in mind that power used during the daylight hours takes away from the battery charging that would run things at night.
