Two questions... as the input I doubt would exceed the current used is
there any problem just hooking the panel direct to the house battery
without a regulator?



Not a 20 watt panel like you're looking at. 20 watts is NOTHING! 20
watts is an anchor light. Only problem with that is it's only 20 watts
at NOON on a bright, sunny day with no clouds and no obstructions shading
the panel. It's only 20 watts for a couple of hours. The anchor light
is from dusk to dawn, 10 hours to 14 hours.

Charging the battery with a 20 watt panel and the tiniest fridge running
off the batteries will kill the battery 2 hours later than without the 20
watt panel....if the sun is bright, of course.

We need KILOWATT HOURS, not watt hours....Big difference!
