Jerry,
There are many sources now for solar equipment. And unfortunately, there are many shysters surfacing (like the guys who sell solar stuff from the back of their truck in Quartzite).
I will admit to being
slightly biased in my opinions as I sell and install products from AM Solar (
www.amsolar.com). You can go cheap or you can go quality. In the end, quality will rule every time!!!!
The heart of any solar charging system is the charge controller. AM Solar manufactures their own design controllers which are made right here in the USA! (imagine that!)
The next important piece of equipment is your battery bank. AGMs are the best for use in a solar charging system as they have the lowest internal resistance of any battery and will re-charge with the least effort from the solar panels.
Let me know if you need more info on a custom system....but definitely check out AM Solar's web site!
