Need a educational lesson on solar Panel

Question

Need a lesson on solar panel.Have a Fleetwood DP that has 4 6 volt house batteries in series and two 12 volt chassie batteries. The MH is not plug into shore power while sitting. I purchased on Amazon a 12 volt, 100 watt panel. Knowing very little about this subject, will this system be able to maintain my batteries. Nothing else on the MH will be on.Thanks for the lession.

A panel is not a solar system. Panels equaling at least one solar watt per battery amp, a controller from a known manufacturer and rated to at least the number amps put out at max by the panels, and adequately large wiring with your batteries is a solar system.

This tutorial is fairly good. https://roadslesstraveled.us/rv-solar-power-basic-concepts-components-and-installation-tutorial/

You will need at least 200W to maintain your batteries. I’ve learned quite a bit from this guy, DIY Solar with Will Prouse.
He has a lot of beginner videos that will give you a lot of info to start. Start from the beginning of his videos and go from there.

Personally I think at least 400W is the way to go with a good MPPT charge controller.

A 100 watt panel will do fine for just maintaining your batteries. You most likely will have a problem doing both the chassis and house batteries at the same time because typically there is a battery isolator in the system. You could jumper around the isolator while in storage. You will also need a charge controller. A cheap PWM type would work fine.

100 watts at 12 volts = 8.333 amps. Just be sure the batteries are fully charged before you park it. I would get something you can add on to....a larger controller that would handle a few hundred watts.
