Welcome to the Colorado AR-15 Shooters Club Discussion Forums.
Bueller? Sorry did not see your previous question: Yes 100w panel and the battery is 550/690/140 SRM24 type. Not my favorite, but it'll do until I can change it for an AGM or 2-6V deep cycle.Originally Posted by Irving

Nice!! Congrats!
Well, the 100 watt panel and controller showed up a bit ago. Inside the box, everything is soaked and covered in black mold. WTF. Box outside though doesn't appear to have been wet, must be humidity of where they are storing the stuff or something.
Panel appears to be ok, haven't checked the controller yet. Maybe later tonight. I'm still waiting on the extra long solar cables and the mounting brackets.
Two orders today from amazon, both have had some issue with them. ugh.

That doesn't mean "stairs are bad" nor does it make someone who pushes someone down the stairs any less of an asshole.
That sucks! Take pictures and contact them, they will overnight a replacement.

update; controller appears to be fine, panel works, so I'll just keep it and install it, i'm running out of time to get a lot of stuff done!
I wish it would stop raining for a few days, I need to pop up the camper and get some wiring done! I don't need the whole thing soaked and pack it back up so the mold starts eating the canvas.

CRUTCH!
At this time I've decided to not mount the solar panel on the camper, I'll just set it up outside. I can move it around if needed then and keep the camper in a shady spot if possible.
I was looking for something in the garage to make a set of legs to tilt the solar panel, well...

I did dry camp for the second time this week-end at twin lakes and with the amount of sun we had I was able to not only recharge the battery, recharge the phones / ipad, and get enough juice to recharge the "campground neighbor's" battery. Poor soul bought a harbor freight generator.... The thing nearly exploded on friday evening after 2 hours of bothering the whole campground at diner time..... I thought the guy was a jerk, but he just ended up to be ok, shared a couple of beers with me and his wife made a killer peach cobbler on saturday. He is returning the geni and ordering some panel.

Your panel doesn't really drive the size of your battery, Irving.
Figure out how many amps you will be drawing.
Then, how many days without sun do you need to support that draw.
Try to plan to never go past 50% discharge.
Buy your battery accordingly.
Rough guess for what it sounds like you guys are shooting for on the campers, I wouldn't run anything less than 100ah. I would actually suggest 2x of the Duracell SLICG110 batteries wired in series. Ends up being about 50% of the cost of a 12V deep cycle, and they handle the constant up and down better (in our experience)(We have solar arrays here, Wyoming, and ND, and not a single on has failed).
ETA:
Batteries Plus usually has those duracells in stock.
Helpful tool for all this kind of stuff, it may have already been posted, but I refer to it when I need a quick set of numbers. It's not perfect, but it will ball park stuff pretty well.

I'm asking what size battery they are using. However, given what you've assumed, it seems like everything drives everything a bit.
"There are no finger prints under water."
Battery I'm using is a BCI GROUP NUMBER: 27 deep cycle from Checker/O Reilley auto parts. My research on the internet said that their deep cycle battery was made by Deka. Which should be a good battery. The previous one I had was original to the camper, InterState Deep cycle, lasted 6 years. We camp a couple times a year, only a few times have I needed the heater all night long and the battery kept up.
I'll confirm the size/amp hour of mine tomorrow. But I'm just using the solar panel to replenish whatever we used during the night. The panel in good sun should put back into the battery at ~ 5 amps an hour. That's a decent charge.
