Panels put out voltage. MPPT charge controllers deal with battery chemistry and charging requirements.

36"x 24" sounds about right for a 100 W panel. It's a pretty great deal.

I don't think you "power" anything with these. You use these to charge your batteries or a power station for energy storage. With batteries, you would use an inverter to convert that stored energy to usable 120v ac power (typical power stations have an inverter built in). So, the short answer is nothing and almost anything depending on how far down the rabbit hole you want to go.
