I've been researching solar and was reading old threads. Thought I'd pull together a list of all the solar threads we could find to make it easier for reference- similar to the Ultimate Awning Thread. I'm going to link to old solar threads and then another section for links to external websites with good solar info. So, if I've missed a thread or you know of something we should add, just post and I'll add it to the first post.

Very nice, thanks.

Remember, this isn't everything (yet!) Don't be shy about letting me know what else should be included.

Ok, so here's my first dumb question (you knew I'd have some right? )

If I bought a 65W panel like this one say, I'd have all the stuff I'd supposedly need. The description says this panel puts out 65W or in 8-hrs of sun it generates 206amps. I'll assume they mean amp hrs. I figure that I use up about 30AH per day. For example purposes, that means my 75AH battery would have about 45AH left after a full day. If this panel generates 200AH+, them my battery would be topped off and I'd "waste" the other 170AH right? In this case, wouldn't a smaller panel be sufficient?

Brett,

The way I understand it, the solar panel will generate 206 amp hours PER WEEK, not day...

Hope this helps

WHAT?! Who came up with this convention?

If so, that would be 29AH/day or 3.6AH per hr. So for argument sake, if I used say 15AH per had and this panel generates 29AH/day, the extra 14AH just goes to waste right? And the charge controller sees to it that it doesn't over charge the battery correct?

[randygirl]

That is the amps per hour the solar will produce in IDEAL conditions. As we know, conditions are not always ideal. Also take into account the voltage loss between the panel and the controller (depending on the distance they are from each other) and you'll be glad you have the 14 amps cushion!!

I hope I am explaining this right.

What are you running with the battery? Are you wired for the battery to charge from the truck while driving?
