I'm working on Solarizing my Scamp 16. I need something like 250 - 300W, and after extensive study, I determined that I can do it with a single panel if I use 24V. But I'm finding 24V panels to be much less available than the 12V. One source that has some choices wants $210 to ship me a $250 panel. I balk at that. Many other vendors have minimum orders - they won't sell just one.
What sources does the collective web-wisdom suggest for panel purchases?
