An excellent forum to consult is solarpaneltalk.com, go to the 12v rv and camping forum.

Lot of knowledgable people, number of engineers, but they can be grumpy when dealing with survivalists or environmentalists. Read the sticky posts on the various forums for a good education.

Myself, I have several small panels, 60 and 100 watt, some 40 or 50 Ah batteries, and charge controllers, plus D.C. Powered aa battery chargers etc. I standardized all my battery stuff on aa and have a supply of eneloop aa batteries.

Also a goal zero unit with some led lights. GZ tends to be expensive, so check out anker small solar panels.

Another source for,info might be modernoutpost.com, which sells stuff but has some educational articles. Also, thewirecutter.com has some ratings on some solar stuff.
