solar back up power

Hi
I recently ask about solar power and got good suggestion with a 50w solar panel and 2 deep cycle batteries.

I saw on ebay some system ready to conne t with 100 or 150 w solar panel.

my question is :
if the number of watts is bigger
1) faster the batteries will charge
2) or more batteries I can charge in the same time

right?

It depends on your controller, but generally yes, you will either be able to charge faster or be able to charge more at the same rate. Though, as a side note, generally anything faster than a trickle type charge will end up shortening the battery life or even make it explode. J

watts=amps x volts

I used this video as a reference to build a small solar light and water feature for my house. It was in a location where running electrical would be way out of my price range for some weird permit/code issue. So i used some marine deep cycle batteries and a solar kit with inverter, It is low draw, so lasts all night, but I would imagine the concept would be similar. Myself, i woudln't do it this way to a building, since open electrical wiring like he has is dangerous for a bunch of reasons.

edit: oh, on the how quickly you can charge issue
