Hello,
I would like to compliment you guys on the site. It seems very informative and I look foward to going over the site in the next few days.
Now for my question: Basically, i'm planning on building some homemade solar panels. Most likely they will be made from pre tabed factory blemished ebay cells. I'm sorry to be so vague, but i am unsurea exactly what cells and contoller i will be using. I know that i am shooting for a twelve volt setup to charge car batteries and a few small deep cycle batteries. I will most likely build a panel under 100 watts and use about a 10 amp cheapo solar controller.
What i'm unable to figure out though, is how many volts my panel needs to make. I've asked a few people and have gotten answers from flat 12v all the way to 18+. I'm sure that it will mostly depend on what the controller will handle. But basically i just want a great functioning and portable way to charge batteeies from boats to cars to laptops while i'm away from a power outlet.
Sorry if i confused anyone. It's late and if i need to clarify anything feel free to let me know.
Thank you all for taking to time to read my post. And hopefully i can get this last hurdle beat.
