Most small battery maintainers are 1.5 to 2 amps and do the job quite well.
Yes but they are also charging 24 hours a day while solar not so much.
I plan on about 2/3 of the panel wattage for 4-6 hours a day for my flat mounted panels. Tilted panels are an improvement. Tracking panels are another step up but very few have that capability.
A 15W panel might not keep up with the self discharge of a battery.
You may be right, I just know the small panel on our MH keeps the batteries charged as long as there is no load. I say no load, the ECM is a load but the panel seems to handle that okay.
